Fedora 16: How to diable boot splash screen?

attempt #1: removing all packages found by “plymouth” with “gpk application / Package Manager for GNOME” => fail boot splash screen still appears.

attempt #2: edit kernel command line options, remove “rhgb”:

$ sudo vi /etc/default/grub

GRUB_CMDLINE_LINUX=”rd.md=0 rd.dm=0 rd.lvm.lv=vg_sommer/lv_root KEYTABLE=de quiet rd.lvm.lv=vg_sommer/lv_swap rhgb rd.luks.uuid=luks-***** SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8″

GRUB_CMDLINE_LINUX=”rd.md=0 rd.dm=0 rd.lvm.lv=vg_sommer/lv_root KEYTABLE=de quiet rd.lvm.lv=vg_sommer/lv_swap rd.luks.uuid=luks-***** SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8″

$ grub2-mkconfig -o /boot/grub2/grub.cfg

=> This leads to success!

edit: replaced hdd id with *****

Linux: XFCE desktop environment: No borders around the application windows and how to fix it

mgmechanics — Sun, 20 May 2012 07:24:12 +0000

Problem: After log in a XFCE session the borders around the application windows were missing. There is also only one desktop available.

Reason: The xfwm4 window manager (= the application which provides the borders araound the windows and more) isn’t running. This usually happens after a session was not closed properly.

Solution:

(1) Go to Applications menu > Run program or press Alt+F2.

(2) Type “xfwm4 –replace” in the input field and press run. Do not toggle “Run in terminal”.

(3) Log out from current session making sure “Save session for future logins” is toggled.

Everything with XFCE should be fine even after reboot now.

A fool issue with Swing / Open JDK 1.6

mgmechanics — Sat, 19 May 2012 09:34:38 +0000

A fool issue with Swing / Open JDK 1.6
current package (Fedora 16): java-1.6.0-openjdk-devel-1:1.6.0.0-65.1.11.1.fc16 (64-bit)

My application [1] uses a class which handles the data (storing + calculation) [2], a JTable the present it and a JTableModel to connect data and JTable: JTable -> JTableModel -> data class. When removing a data set the application tells the JTableModel which calls the data class to remove the data set and runs the fireTableRowsDeleted(…) method to tell the JTable to remove the corresponding row.

This works fine if there is no cell in the edit mode. Otherwise – if a cell is in the edit mode – an exception (java.lang.IndexOutOfBoundsException) thrown from JTableModel telling that the JTableModel tries to read an index at data class which does not exist. I.e.: data class has 3 items (0..2) the removing item 2 raises the exception “java.lang.IndexOutOfBoundsException: Index: 2, Size: 2″ while the data class has now two items and JTable has now 2 rows => JTable and data class removed the items as it should but JTable did not recognize the change. A similar issue appeared when adding rows. Adding / removing columns is not a problem in my application because my application because adding or removing columns is allowed only in a JTable which can not be edited but if your application permits it the same problem would occur.

The solution was to kick all cells out of edit mode by running the JTable.editingCanceled(ChangeEvent) method for the JTable object i.e. (“table” = JTable object): “table.editingCanceled(new ChangeEvent(table));” before removing or adding items.

Linux, Fedora 16: How to turn Advanced Power Management less aggressive (only if you really afraid about your hard disk)

mgmechanics — Sat, 19 May 2012 08:07:19 +0000

Some people hear a click-clack noise while working on their notebooks running linux. The reason was found to be a too aggressive power management which could cause the hard disk die prematurely. Here is an article about this problem and possible solutions (in german): “Linux User” 2012-01 “Bund fürs Leben” page 66 ff..

On a ASUSTeK Computer Inc. notebook model A54C (see last recent article in this blog) which comes with an “Seagate Momentus 5400.6 / ST9320325AS” hdd and runs Fedora 16 I decided to turn down the power mangament. There was no need for it (see this recent article). I just see no sense in a aggressive power management since I use to work when notebook is on power and switch it off when finished working. Furthermore, aggressive power management was used when the notebook runs on AC!

The Advanced Power Management was set to 128 by SMART software (that means by the hdd itself). I found this by executing:

$ sudo hdparm -I /dev/sda | grep “Advanced power management”

Advanced power management level: 128

The value can range between 1 (= VERY agressive) and 255 (Advanced Power Management off). I decided to reduce it to 240. Don’t ask why this value – I just guessed. One one hand I want the hard disk to be capable to do some Advanced Power Management but I dont want it to be agressive. I avoided a value of 254 because someone observed his hdd running hot.

To have the change permanently we need to set it again after each power-off (I observed that this change was still available after reboot). _This is done by placing a command into the file /etc/rc.d/rc.local and run it as root. Running as root is done in my solution by setting the “s-bit” for the /etc/rc.d/rc.local (for the user only, the file is owned by root of course). (The s-bit is a flag which allows a program to run with the rights of it’s owner.)

This are the steps I made to change the level of Advanced Power Management permanently (lines starting with $ means that I typed a command into terminal, lines without $ right below tell what the command print out):

1) Looking for file /etc/rc.d/rc.local:

$ ls /etc/rc.d/rc.local

ls: cannot access /etc/rc.d/rc.local: No such file or directory

/etc/rc.d/rc.local didn’t exist.

2) Find out how your hard disk(s) is (are) mapped. If you have only one hard disk in your computer it should be mapped as “/dev/sda”. Launch GSmartControl to check. I can see two drives:

(A) “ST9320325AS” (text following “Drive information” starts with “/dev/sda”)

(B) “CDDVDW SN-208BB” (text following “Drive information” starts with “/dev/sr0″)

Drive (A) is the hard disk. I did not try this with external drives!

3) Create a file named rc.local in your home folder. Use you favorite text editor e.g. Acessoires -> gedit for it. Put this two lines in the file (if your hard disk is mapped on “/dev/sda” otherwise replace “/dev/sda” by the mapping for your hard drive!!!):

#!/bin/bash

hdparm -B 240 /dev/sda

“240″ is the level of Adavanced Power Management you wish. Please note the the command “hdparm” could kill your hard disk if used without knowledge. Thus I use the -B parameter with values greater than the default value only.

4) Open a terminal e.g. System -> Terminal and change into the folder there the file exists.

5) Give the file the proper owner and read-write-execute rights. Note that we need :

$ chmod 755 rc.local

$ chmod u+s rc.local

$ chown root:root rc.local

6) Now check the file. Mine looks like:

$ ls -l rc.local

-rwsr-xr-x. 1 root root 36 May 2 23:12 rc.local

7) Now copy this file into the folder where it will run when the machine boots. This command ask for the root password (the paasword you use to change something on the operation system e.g. install a printer):

$ sudo cp rc.local /etc/rc.d/

8) Reboot your machine.

9) Check if it has effect:

$ sudo hdparm -I /dev/sda | grep “Advanced power management”

Advanced power management level: 240

If you want to try it just until next power-off:

$ sudo hdparm -B 240 /dev/sda

Check as written above.

With this value I observed counting the value of “193 Load / Unload Cycle” (by GSmartControl) in 41 hours from 1080 to 1102. I could not observe any effect on battery runtime. This notebook (Asus A54C on Fedora 16) runs still 2 hours on battery. In opposite, turn down screen brightness has an effect on runtime for sure. One could also switch off wireless network if not needed (See installation report for Dell Latitude E4300 in this blog).

Linux on laptop: Fedora 16 on Asus A54C

mgmechanics — Fri, 18 May 2012 08:22:44 +0000

Install Fedora 16 on an ASUS A54C notebook

Build-In hardware overview

Hardware overview taken from manufacturers description or Windows 7 hardware info (this one in “”):

Vendor: ASUSTeK Computer Inc.

Model: A54C-SO325V, version K54C

Display: 15″ NON-GLARE, resolution 1366×768, LED-Backlight

Battery: The battery is quite tall. I don’t know the capacity but my Dell Latitude E4300 has a bigger battery and I knew this is a 6-cell battery.

CPU: Intel B940 (2 x 2,0 Ghz)

RAM: 4 GB / 1333 MHz

Mainboard chipset: “Systemdevices”: “Intel(R) HM65 Express Chipset Family LPC Interface Controller – 1C49″ + “Intel(R) 82802 Firmwarehub”

Graphic chipset: “Intel(R) HD Graphics Family”

Sound: “Audio-, Video- und Gamecontroller”: “Intel(R) Display-Audio” + “Realtek High Definition Audio”, on the case is “ALTEC Lansing”

USB: USB 3.0 is available says the sticker on the notebook. The left hand USB port has a blue plastic part inside, the right hand port a black one. Left port = USB 3.0 and right port = USB 2.0? Windows 7 tells: “USB-Controller”: “Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller – 1C26″

Ethernet adapter: “Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)”

WLAN: “Atheros AR9285 Wireless Network Adapter”

Hdd: Windows 7 tells only the Device Model thus here is more info by Linux/GSmartControl: Model Family = Seagate Momentus 5400.6, Device Model = ST9320325AS (same as Windows 7 tells), capacity 320 GB

DVD-RW drive: “TSSTcorp CDDVDW SN-208BB”

SD-Card drive: I don’t know.

Mouse: “Synaptics PS/2 Port TouchPad”

Webcam: “ASUS USB2.0 WebCam”

OS: sold with pre-installed Windows 7

Price: 379 EURO (Germany April 2012)

Additional hardware tested here:

- usb surf stick (usb device for UMTS connection): “XS Stick (r) W14 / http://www.4g-systems.com”; (there is “klarmobil.de” printed on it)

Notebook

This machine is not made for shining but for working. I use it mainly for developing and office. It has a NON-GLARE display. Even the case and the frame around the display are “non-glare”. The display provides a bright, sharp picture and text is good to read even if some sunlight is shining on it. Usually I turn down brightness. The case is made of black plastic with a surface which comes with a texture so that it is not smooth (“it has grip”). The case is stable. Touch pad buttons are of black plastic (also not smooth) which make an audible click sound when hitting it. This sound could annoying people around you. Mouse clicks can be – with Fedora 16 – send only by this buttons. Think twice before using it in the “Ruhebereich” at Deutsche Bahn :-) The fan is audible when I use the nootebook in silent room but not when there is other noise e.g. in a office. The keys on keyboard has some space between – good for typing. “Delete” key is above backspace key and “End” (go to end of line) key is in the upper right corner. The arrow keys (move up-down-right-left) are far away from page-up and page-down.

Size: The size of screen and case is suitable for work in the ICE-trains of Deutsche Bahn (= German Railways).

Operation System

First i installed and run the pre-installed OS to see if all components are working. Everything was fine. Windows 7 (without additional software) runs fast und boots quickly. Then I tried a Fedora 16 live system because an article in the press (c’t 2011, Heft 20, Thorsten Leemhuis: “Arbeitspinguine” used Fedora and Ubuntu to test some laptops and found that Fedora has better results). It worked fine especially the x-Window system worked fine. The whole screen was used to display. Then I installed Debian testing snapshot (dated by Debian to be of 2012-04-23). I toggled the XFCE desktop to install and the “expert mode”. After install the system booted only into text login. Command “startx” seems to lock the termial but no X-Windows system appeared. (Did I make a mistake during install?) I logged in on another terminal and shut the system down. The I rebooted Fedora 16 live demo again. It worked fine and due lack of time to try other options I installed it. After installing I found all the hardware listed above working perfectly even webcam and microphone.

Build-In hardware test

Function keys like making screen brighter/darker, sound louder/quieter, switch wireless network devices on/off: works.

Touch pad: Scrolling by moving the finger on right border doesnt work but gestures works! To scroll just put one finger on touch pad and move another finger up-/down or legft/right. Mouseclicks works only by touch pad buttons which produce a noticeable “click!”-noise when hit. This could annoy other people next to you.

Battery: The manufaturers says the laptop should run about 3 hours. Running XFCE4 with reduced display brightness let it run out of power after 2 h. No tweeks were made. My Dell Latitude E6400 with 13″ Screen has a bigger (6-cell) battery and runs 4.5 hours with XFCE + debian testing (coming Debian 7). Compared to screen size (15″ vs. 13″) and prize the 2 hours seems a good deal for me.

The battery applet works. Runtime seems to depend very on screen brightness. Loading the battery while the notbook is running (with reduced screen brightness) takes about 1.5 hours.

Hdd: The hard disk runs quiet. I can’t hear any noise from it. There was no “click-clack” noise with default settings. The Advanced Power Management was set to 128. (As I understood it this value came from hard disk and Linux is not in duty to change it.) The value of “193: Load / Unload Cycle” reached 1000 in about 24 hours running (value of “9: Power-On Time”). The 24 h splits in running 22 h on AC and 2 h running on battery. Its about 42 Load / Unload Cycles per hour. This means a runtime of about 14286 hours until reaching the value of 600k which some people see as being maximal number of Load / Unload Cycles which most hard disks can reach before get broken. Assuming that you are using your laptop 10 h per day and 360 days in a year that would mean you can use it about 4 years. Basing on this calculation there seems to be no danger that this hard disk running Fedora 16 will die prematurely when using Linux. “Linux User” 2012-01 “Bund fürs Leben” page 66 ff. provides an article about it. There is an easy way to turn the power management less aggressive. I will describe it for Fedora 16 in the next article on this blog.

Usb surf stick: The usb surf stick works out-of-the-box. When the usb surf stick is sticking on left usb port I need to remove it before power-off the notebook since I the notebook reboots instead going power-off. When the reboot finished the system runs stable. When power-off it reboots again running stable after reboot! I tried same with this usb surf stick sticking in the right usb port: When I select power-off the notebook is going power-off. Another issue with this usb surf stick: When first trying it didn’t work. I found the reason to be as the SIM Card wasn’t sticking deep enough in the stick. I used a knife to push it deeper into the device. Then it started working.

External VGA connector (analog): Very good result on a flatscreen @ 1920×1080.

SD-card drive: Tried 16 GB SD-card: Worked out-of-the-box.

Sound: Internal speakers and external headphones are working. Internal speakers are off when external headphones are plugged in.

Notebook

This notebook is a light-weight high-end notebook. Of course it was expensive. But I travel a lot and I wanted to get rid of the bigger and heavier Toshiba A100-589 (reported earlier in this blog) AND I wanted a high-end machine to work quickly with Windows.

WHY I WOULDN’T BUY IT AGAIN: Mine seem to have a hardware fault. It was delivered with Windows Vista Ultimate SP1 (90 € extra to pay). With this the system freezed from time to time as we know from Windows 9x. I (this was an error) blamed Windows Vista for the freezes and deleted it in favour of Linux after I sucessfully tested Linux about 3 months. Later Linux started also from time to time esp. when watching flash movies with Adobe(R) Flash(R). Now I blamed Adobe Adobe(R) Flash(R) and this was wrong again. I realised that crashes occurs when the system asked for extra power. I called Dell service. After changing the whole mainboard no freezes happend! Sorry Microsoft + Adobe, that I blamed your software. It was an error. I didn’t buy an warranty enhancement thinking the issue were fixed – after time of warranty was over the system started to freeze again. I found a feature in the BIOS named “Intel speed step” and disabled it because I observed the freezing when the system need extra power. This fixed it – almost (two freezes in 8 months). I always used the Ext4 file system with encrypted home directory (ecryptfs) which always protected my data (truecrypt drives among it). I found no file damaged or lost. MANY THANKS the people who made the Ext4 file system!!! Because of the descripted behavior this notebook was replaced by a Asus A54C (also reported in this blog). After there is no need for running Windows because I am happy with Linux I feel no need for such a high-end machine. For Linux and what I am doing with it (developing and office) a low-end machine is good enough.

Operation System

I installed Debian 6 “Sequeeze” stable, updated it and switched then to the testing branch of upcoming Debian 7 “Wheezy” (both 64 bit). Earlier I had Ubuntu 8.10 – 10.04 (32 bit) on it but this is not the scope of this report.

Build-In hardware test

Keyboard, mousepad, USB: Works out of the box. Localisation is de_DE_UTF8 (I selected german localisation). Pressing “Y”-key prints an “Y” not “Z”. Can type Euro-Sign €, |, @, \, ÄÖÜäöüß (AOUaou-umlaut + sharp s). Mouse moves, mousekeys works, (after changing the configuration through the graphical program which come whith Gnome for this purpose) double-hitting the mousepad works also. Can connect and disconnect USB-devices.

Network: Ethernet + WLAN works out of the box. Internal USB-modem needed use of wvdial for Ubuntu 8.10 only, later I could do out of the box with Gnome’s and KDE’s graphical network managers.

Graphics: Resolution of built-in screen is 1280×800. This laptop comes with an external VGA-connector (analog). Connecting it to a Flatscreen it shows a very useable view. I had resolutions up to 1920×1080 on Ubuntu.

Sound: Works out of the box, very good. Even the volume-control shortcuts on keyboard works.

DVD: Can burn DVDs even video DVDs.

SD-Card drive: Works fine (read/write).

ACPI: Fan runs only short from time to time. If the machine has to work harder, the fan starts running (in two steps) but stops running withinsome time after work load is done. The machine did never overheat.

Battery: It runs 4.5 hour while developing (writing, compiling, running).

Debian testing: Can’t log in to Xfce – and how to fix this

mgmechanics — Sun, 01 Apr 2012 14:20:16 +0000

Last Wednesday I turned on my Laptop and tried to log in to Xfce desktop as usual. But after typing in my password and hitting Enter the system worked a moment and then a saw the window for graphical log in again. For cases like this (or when I like a change) always have a second desktop installed (LXDE). I could log in using LXDE without problems.

With Google I found this Can’t log in to xfce. It says: "Recently I solved this by deleting /~/.ICEauthotity ". OK, I renamed this file in my home directory to _ICEauthotity, made a fresh backup (one but not the only reason is that I use an encrypted file system to protect my data ;-))) and rebooted.

I was able to log in to Xfce again!

What may happened?

.ICEauthority file when I was unable to log in to Xfce (renamed to _ICEauthority):

-rw------- 1 michael michael 0 Mär 28 18:46 _ICEauthority

.ICEauthority file when I was able to log in to Xfce:

-rw------- 1 michael michael 330 Apr 1 16:54 .ICEauthority

The .ICEauthority file was empty!

Conclusion:

1) You may delete the .ICEauthority file – Linux can restore it on next reboot

2) When the .ICEauthority file is empty it may cause trouble like you can not log in to your desktop.

3) It was a good idea to have a second desktop already installed.

Debian GNU/Linux: How to open a JNLP – file from Iceweasel

mgmechanics — Sun, 25 Mar 2012 18:01:48 +0000

I just wanted to start a Java application from a website from Oracle Java examples – and Iceweasel offerd me to open the JNLP – file with Iceweasel or to download it. How load and run it automatically? Solution: Just install the icedtead-netx package. It installs javaws (which was missing) and configures Iceweasel so that it offers you "open with: IcedTea Java 6 Web Start (default)" without any further effort.

SourceForge.net: Trouble with connecting via SFTP using FileZilla after password change

mgmechanics — Fri, 23 Mar 2012 22:25:12 +0000

Recently I changed my password on SourceForge.net. After the change I wasn’t able to connect to the Developer Web using FileZilla. FileZilla just said: “Error: Authentification failed” (and so on). I found neither help nor any information what the reason could be. Of course I tried the old and the new password. After hours of searching and trying I found a solution:

(1) I generated a new SSH-Key of type RSA (using a nice tool named “Seahorse” on my Linux) wich doesn’t require a password .

(2) I uploaded the public part of the key to SourceForge.net (log in and go to Account -> Services, there is a link named “Edit SSH Keys for Shell/CVS” – click on it and insert the key).

(3) I told FileZilla about the private part of the key (its in a hidden folder named “.ssh”, the name of the file is the same as of the public part but without “.pub” at the end) by going to Preferences -> Connection -> SSH. FileZilla complained that it can not deal with keys which need a password (we set up the key such that this is true for our key: I we don’t need a password to use it) and that it need to convert the key. Just convert it – the original file will be not overwritten.

Now I can access SourceForge.net’s Develeoper Web again.
