I have installed ubuntu 11.10 on my laptop hp 6735s. The screen is often too dark and i want to make it brighter, although the hotkeys Fn+F7/F8 are not working.
I have tried some things:
- Firstly it appears that sometimes they are in fact working, after reboot they either work and continue to do so or they don't.
- I've read about a brightness applet; but where can i find or install it?
- I have tried some grub options;
acpi_osi=Linux and acpi_backlight=vendorbut nothing changes.
- I don't want to add another question but since it might be related: my laptop also gets quite hot, i'm having doubts whether ubuntu connects to the available sensors and cooling plans (or how does it work???); sensors (or psensor) only shows 2 sensors both named temp1.
Any help is greatly appreciated!
