For one of my attached USB devices (2773:0104) I see no description in lsusb command output:
user@Thinkpad-Laptop:~/binaries$ lsusb
Bus 008 Device 002: ID 0a5c:217f Broadcom Corp.
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 036: ID 2773:0104
Where USB description is comming from, is it from device driver or is it stored in the hardware itself ?
After trying to fix my subwoofer problem sound indicator icon is always showing dashes and Sound Settings panel is empty (no audio profiles available, screen attached). Strange that the sound itself is working, I am able to play files. I tried to google but couldn't find the solution. Any ideas ?
My application running on a laptop-like device is controlling battery status on its own but when laptop battery is critically low Gnome Power Management message box appears:
As my GUI style is totally different I would like to permanently disable / uninstall this Gnome feature. How to achieve this ?
EDIT:
I am on Ubuntu 10.04 LTS
I have a usb stick with two partitions FAT 32 adn ext3. First one is used to boot from using SystemRescueCD. Second one contains the image I use with image recovery tool.
I have to copy such an usb 10 times so I thouhgt maybe there is an easy way to do this,
something like cp /dev/sdb ?
Is there a simple way to check whether or not my Ubuntu machine is part of a botnet?
I have a problem on my Ubuntu 10.04 machine with audio output. When playing audio with a headset connected it can be heard on speakers and headset in the same time. It is similar to other questions I found on internet. But what is different is that when I change channel balance to left then only speaker is used. When I changed it to the right only headset is used. It looks like speaker is treated as left channel and headset as the right channel.
My machine is a custom build Intel Atom based PC.
Audio driver snd-intel8x0

I have many files with .abc extension and want to change them to .edefg
How to do this from command line ?
I have a root folder with many sub-folders, so the solution should work recursively.
Is there a place where I could check what are the differences between kernel in version 10.04 and 10.10 ? The reason is that from time to time I have total system freezes with 10.10 on Dell Inspiron 1501 which was no the case on 10.04.
My Ubuntu 10.10 sometimes totally freezes. I suppose that it is somehow related to my graphic card and would like to check Xserver log. Where is this file located ?
I have an embedded battery powered device running Ubuntu and want to reduce power consumption. The idea is that if a user does not use a device for ca. 30 min. then the device will automatically shutdown or hibernate.
Is it possible to automatically shut down or hibernate Ubuntu after spending x minutes in suspend?
Is there a tool like Windows DependencyWalker for Ubuntu ? I would like to see all shared libraries my executable depends on.
From one of my customers I got an application. When I try to run it I got following error
error while loading shared libraries: ./libvtkWidgets.so.5.4: file too short
In my project structure I see following:
-rwxrwxrwx 1 tomasz tomasz 20 2011-02-01 10:44 libvtkWidgets.so
-rwxrwxrwx 1 tomasz tomasz 22 2011-02-01 10:44 libvtkWidgets.so.5.4
-rwxrwxrwx 1 tomasz tomasz 2147103 2011-02-01 10:44 libvtkWidgets.so.5.4.2
Is my shared library libvtkWidgets corrupted ? How to solve that error ?
When I type
set | grep -i proxy
I see all environmental variables which refers to proxy settings. I understand the meaning of http_proxy and ftp_proxy but what is all_proxy used for and where can I change it ?
It has been added to my environment variables when I used gnome-network-properties application. Why socks is specified there as a protocol?
all_proxy=socks://my_proxy:port/
For the command
sudo apt-get update
I get following error:
W: Failed to fetch http://ch.archive.ubuntu.com/ubuntu/dists/maverick-updates/multiverse/binary-i386/Packages.gz
407 Proxy Authentication Required (The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )
I am running Ubuntu 10.10 installed on Windows XP using VirtualBox. For Internet connections I am using proxy server with an authentication. I tried to use gnome-network-proxy tool to set proxy settings system-wide.
After that /etc/environment has been updated by http_proxy variable with the format http://my_proxy:port/, there were no authentication data.
I checked this with Firefox. Browser asked my for login and password and everything was working fine. It was unfortunately not the case for apt-get. I have also tried to do as described here. Unfortunately it does not work.
May it be somehow related to the fact that a proxy is in a Windows domain, any ideas?
My proxy name is http-proxy. Is '-' a special character here?
