Note: Also applicable for Ubuntu 10.10/10.04. If you are running Ubuntu 11.04/11.10 and your computer stops making sound for no reason, then I suggest that you follow the instructions given below to restore sound back to your computer. Before we start, you should know that these solutions are some from many solutions available to fix sound issues. So, they may help some users, and some not. Unmute Sound With AlsaMixer 1. Launch the Terminal and issue this command: alsamixer If AlsaMixer it is not installed, then install it with this command: sudo apt-get install gnome-alsamixer 2. Using your keyboard arrow keys (Left/Right/Up/Down), unmute PCM and Front: 3. The sound should now work fine. Press Esc to exit AlsaMixer. Restart ALSA Audio Driver If your audio device is not listed at all in the Hardware section, then try to restart your ALSA audio driver with this command: sudo alsa force-reload Note: Sound may disappear after rebooting your system. Reinstaling Missing Sound Modules If your audio device is not listed in the hardware tab of your sound manager, then your sound modules are not installed. To fix this, run this command via the terminal to install missing sound modules: sudo aptitude reinstall linux-generic Reboot now your system. The sound should now work fine. Onboard Realtek ALC887 If your motherboard has an onboard Intel HDA audio (ALC887), then follow these instructions: 1. Open the Terminal and run this command: sudo gedit /etc/modprobe.d/alsa-base.conf 2. At the end of the file, add this line: options snd-hda-intel model=generic Save the file and reboot your system. Good Luck! wifix is an installer for FLOSS Wireless drivers under a Linux -based system.

All you need is an Ubuntu Live-CD and you're good to go! sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install boot-repair-ubuntu The trick is when you run ubuntu as a live cd and going to install it make sure you go to software center and install calibrate touchscreen and calibrate it. Then you install ubuntu and do the same thing! sudo apt-get install xinput-calibrator or go to software center you can then run it from System > Administration > Calibrate Touch-screen after you have calibrated it will show a terminal output that looks similar to this Warning: multiple calibratable devices found, calibrating last one (eGalax INC. USB TouchController) use --device to select another one. Calibrating EVDEV driver for "eGalax INC. USB TouchController" id=12 current calibration values (from XInput): min_x=0, max_x=4095 and min_y=0, max_y=4095 Doing dynamic recalibration: Setting new calibration data: 77, 3935, 115, 3984 --> Making the calibration permanent <-- copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' Section "InputClass" Identifier "calibration" MatchProduct "eGalax INC. USB TouchController" Option "Calibration" "77 3935 115 3984" EndSection in terminal type: gksudo gedit /usr/share/X11/xorg.conf.d/99-calibration.conf and copy and the paste the calibrations and save it. For eGalaxTouch on Ubuntu 11.10 and 12.04 LTSYou guys might have been running into problems with eGalaxTouch. The trick to get this to work you have to download the eGTouch Daemon driver extract it to home folder open terminal and enter "cd /home/user-name/eGTouch_xxxxxxxxx " then enter "sudo sh setup.sh" reboot calibrate then your done!!
