Bug Description
Brightness control is broken on Acer Aspire 6920G using 2.6.27-11-generic x64 GNU/Linux.
It's not an applet problem, since I updated linux to JAUNTY and applet works properly and is responsive to hotkeys. But even on JAUNTY, brighness can't be controlled and is not responsive.
Actually when I start the system under 2.6.27-11-generic x64 GNU/Linux (on acer aspire 6920G)
- my directory '/proc/acpi/video' is EMPTY
- and LCD brightness can't be changed, both from terminal and FN keys.
- Plus, if I use FN keys, the applet reacts to Brightness- but doens't react to Brightness+
when I start the 2.6.27-9-generic, instead, I have the proper directories and the system (and applet) working.
It's a pity the acpi has broken in this last kernel release.
I have this problem also on my aspire 6935g
