13.10 - Screen Brightness, GUI Crash, Sleep/Hibernate Resume, Mouse Pointer Problems with Lenovo IdeaPad Y500

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.,
