I thought it'd be better to put all my current problems in a single thread.

I've searched for almost 3 days trying to fix my issues. I failed.

  1. I can't change the screen brightness, the bar changes, but the brightness does not. The screen can however dim when inactive for a few minutes.

  2. The GUI crashes sometimes when I drag Chromium to the top. I can fix it by going into ttyX and restarting lightdm, but this kills all my windows and work!

  3. I can't resume from sleep/hibernate: it just shows a black screen on restart and does nothing. (I also get a thaw error -19 when going into hibernation)

  4. The mouse pointer speed can also not be slided, I have to run a script myself. If I go into tty and come back, the mouse is slow again.

3 is my largest concern: It's a laptop and I sometimes have to carry it around for 3 min and then continue work.,

  • This is probably an issue with your graphics drivers. See this post, this post and the "Additional Drivers" tab in the application "Software and Updates". This might also we worth a read. – Seth Nov 17 '13 at 02:02
  • Thank you so much, I hope most issues will be resolved by following these threads. I apologize for not being able to find them and cluttering the forum. –  Nov 17 '13 at 13:15
