View Full Version : [ubuntu] Recent upgrade from 8.04 to 8.10 is causing random change in brightness

hi after recently upgrading from 8.04 to 8.10 i noticed some changes on my Sony Vaio VGN-NR110E.

First off, my volume up/down keys dont work anymore and thats pretty annoying.

Now, the real bizarre thing is that my screen randomly changes brightness. while im working, my screen goes up and down in brightness levels and i cant control it as my brightness up/down keys dont work anymore when this happens. Strangely however, after the brightness reaches 100% i can control it once again. I am checking brightness using xbacklight. And the brightness increases/decreases at increments of about 0.5% but changes very rapidly

Hi I also have this problem, I have a NR498d. This problem only occurs for me when I am running on battery power and for me, the brightness goes to 0% before I can use my brightness keys (the upgrade to Intrepid actually fixed the fn + F5/F6).
