Hi
I am currently trying to get a device with an Intel GMA 500 graphics
chip to run with Debian Wheezy. However, I don't seem to be able to get
anything other than a standard VGA console out of the hardware.
Basically, these are the issues:
- The proprietary Intel driver as well as the psb driver don't seem to
work with / compile against Wheezy's version of Xorg. I am not
particularly saddened by this though since I'd rather get the new,
in-kernel driver to work.
- Which brings us to the next issue: as soon as I load the gma500_gfx
kernel module my screen goes blank. I have no idea whether this is
because of a wrong display resolution, because the backlight misbehaves
or for some other reason. Attached you will find the kernel output that
I get when loading the module.
- Since this may very well be an issue with the display resolution I
decided to try and just run X, hoping for things to magically start
working. With the vesafb driver X does indeed loat but it only runs at
640x480 (according to the log) and I still don't get any video output.
With the modesetting driver X fails to load, the xorg.conf and
Xorg.0.log files for this setup are also attached.
It might be worth mentioning that I have tried kernel 3.2 from Wheezy as
well as 3.12 from unstable and I've also replaced the modesetting driver
from Wheezy (0.3.0) with 0.8.1 from unstable. None of that changed any
of the symptoms.
I am now wondering whether a) the combination of gma500_gfx and
modesetting Xorg driver is the currently recommended way to use GMA 500
chips with Debian and b) what I could be doing wrong, i.e. why my screen
remains blank and Xorg fails to load.
Any hints and suggestions would be appreciated.
cheers
