radeon driver
Status in “linux” package in Ubuntu:
Expired
Bug description:
CID: 201307-13904 HP Pavilion 14
Steps:
1. Install 12.04.3 + update (3.8.0-33), boot to desktop
2. Adjust the brightness with hotkeys
3. Adjust the brightness with the brightness applet.
Expected results:
- Brightness could be controlled.
Actual result:
- The brightness level indicator will change with hotkeys, but brightness
won't be changed, it can't be controlled by the brightness applet as well.
