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 2:02
