Martin,
Looking at some Fedora sites, I see where there are many post of problems with
the Eee PC
and backlighting. Based on what I read, I decided to update the BIOS, and
although it didn't fix the
problem completely, the screen now has about 10% brightness, so I can actually
read it if the room
is not too bright.
some people have reported a fix in fedora that uses grub kernel options:
acpi_osi=Linux acpi_backlight=vendor
I will try putting these in the /boot/grub/menu.lst file.
Is this the right place? Any suggestions?
