[Openchrome-users] openchrome driver problem on Amilo Pro V2030 Laptop

[Coady Buckley-Zistel]

I have run a number of Debian based distributions of GNU/Linux on my
laptop (it is a Fujitsu Siemens Amilo Pro V2030 laptop with a VN800 VIA
integrated chipset). However, when I have recently installed new
distributions I have had a nightmare with the getting the screen
resolution set. There appears to be a bug which will not recognise the
latest openchrome driver (having compiled and installed it). The result
is the X server and desktop will only run with "Display > Modes" set a
"800x600". I can confirm that X server will not run with these settings
(Modes "1024x768" "800x600" "640x480") in the 'xorg.conf'. It will only
run if Modes "800x600". Any attempt to manually edit the 'xorg.conf'
file to include, for e.g., Modes "1024x768" "800x600" "640x480" causes X
to fail to load and no possibility of loading a desktop. It does not
make a difference if 3D is disabled or not. It also does not matter if
"Depth" is set to '16' or to '24'.

I have this problem in Ubuntu 7.10 and Fedora 8. In older versions of
these distributions I have not had a problem compiling, and installing
the openchrome driver and running screen resolution at "1024x768". I
assume it is a problem that results with either the new openchrome
driver, or current release kernels. In Debian 4.0, I can run "1024x768"
using the generic "vesa" driver but I suppose I will not be able to
playback video, etc.

I have posted this problem in the Ubuntu forum (along with files such as
'xorg.conf' and 'xorg.0.log'). Here is the final response to that thread:
----------
(--) VIA(0): Virtual size is 800x600 (pitch 800)
(II) VIA(0): Trying VBE Mode 800x600 (0xc115) Refresh 60.31:

I don't see the exact problem right know, the openchrome driver is
loaded. Please subscribe to the openchrome mailing list and post your
info there.

I have the suspicion it has something to do with wrong DDC of your panel
and the VDE modes of the driver. You can try a manual modeline, manual
panel freq ranges and disable DDC.

I have attached the config and log files for both Ubuntu and Fedora as 
well as some output below. Any help to resolve this would be greatly 
appreciated. Thanks...
