Hi,
I jut got a new powerbook and I installed Debian/Sid with the most
recent version of the distributed Linux kernel (2.6.8). It works fine
but I cannot control the screen brightness. I tried to configure the
framebuffer in the XF86Configure-4 (please find attached my
configuration file) file but the X system gives the following error:
(II) Module fbdevhw: vendor="The XFree86 Project"
compiled for 4.3.0.1, module version = 0.0.2
ABI class: XFree86 Video Driver, version 0.6
(WW) open /dev/fb1: No such file or directory
(WW) open /dev/fb2: No such file or directory
(WW) open /dev/fb3: No such file or directory
(WW) open /dev/fb4: No such file or directory
(WW) open /dev/fb5: No such file or directory
(WW) open /dev/fb6: No such file or directory
(WW) open /dev/fb7: No such file or directory
(EE) Unable to find a valid framebuffer device
(EE) NV(0): Failed to open framebuffer device, consult warnings and/or
errors above for possible reasons
(you may have to look at the server log to see warnings)
I didn't load the rivafb module. It use the offb driver.
Thanks your help,
Zoltan
