Remember Me

OK, so you want to uninstall unwanted program(s) in Ubuntu? After you try it from GUI ways (Application>Add/remove or System>Administration>Synaptic Package Manager) you failed (the program is not listed there). Then you need to do it from command line (Terminal) at last: sudo apt-get remove pdfcrack (uninstall program called pdfcrack) or sudo apt-get --purge remove motion (uninstall program called motion including the configuration files) Happy uninstalling!

My widescreen has gone after updating kernel 2.6.24-19-generic. I don't know why. After trying to fix it by following some links, finally I made it back to the original screen resolution 1280x800. My Sony Vaio VGN-NR120E comes with Intel Graphics. If you have similar problem, you can try this (it worked for me but not guarantee will solve your problem). 1. Open Up Your Terminal 2. Run this command: sudo apt-get install xserver-xorg-video-intel 3. REBOOT your system 4. Edit the screen resolution: System>Preferences>Screen Resolution In my case, after choosing the correct resolution, the screen still behave wierd. Then I reboot the second time. Tha dha, it's solved.
