Comment 1 Søren Sandmann Pedersen 2005-05-03 11:06:32 EDT
Should be fixed in Rawhide. The packages you need to upgrade to check are "rhpl"
and "xorg-x11".

Please reopen if this is still a problem.
Comment 2 Martin Welss 2005-05-03 11:40:22 EDT
I updated the packages with "yum update rhpl xorg-x11".
Configuration now lets me select Resolution 1280x800, but after save and
restart, the resolution ist still at 1024x768
i810 Driver Problem?
Comment 3 Søren Sandmann Pedersen 2005-05-03 11:57:03 EDT
Can you attach (not inline) the generated xorg.conf file please.

(Also please make sure that you actually restarted the X server with
Ctrl-Alt-Del - logging out/logging in is not always enough).

Comment 5 Martin Welss 2005-05-03 12:32:26 EDT
Even after reboot, X comes up with 1024x768
see attached xorg.conf
Comment 6 Søren Sandmann Pedersen 2005-05-03 13:57:12 EDT
What exact release of X do get? Ie., what does "rpm -q xorg-x11" give you?
Comment 7 Martin Welss 2005-05-03 15:14:42 EDT
I got it by doing "yum update" some hours ago.
Comment 8 Søren Sandmann Pedersen 2005-05-03 16:36:13 EDT
The latest version in rawhide is -29. The latest rhpl version is -161. These two
together should fix this problem. You can get them at 


for example. I don't know if there is a yum command that will do it automatically.

xorg logfile from xorg-6.8.2-29

please note the two lines "Not using Mode ..." 
the resolutions are definitvely supported, because Redmond XP can use them :-(

Comment 10 Søren Sandmann Pedersen 2005-05-04 10:21:50 EDT
What does the generated xorg.conf file look like with the upgraded rhpl and the
upgraded server?

Comment 12 Søren Sandmann Pedersen 2005-05-04 11:08:10 EDT
Could you check if the problem is fixed if you change the modeline from

   ModeLine "1280x800_60.00" 83.5 1280 1344 1480 1680 800 801 804 828 -hsync +vsync


   ModeLine "1280x800" 83.5 1280 1344 1480 1680 800 801 804 828 -hsync +vsync

Ie. delete "_60.00" from the name.
Comment 13 Martin Welss 2005-05-04 11:24:26 EDT
no difference (after reboot)
Comment 14 Martin Welss 2005-05-13 08:53:44 EDT
it works now:
- the real resolution is 1280x768 not 800 (my fault)
- I must use the tool "855resolution" by Alain Poirier to patch the buggy bios
to allow this resolution (http://perso.wanadoo.fr/apoirier/)
Comment 15 Søren Sandmann Pedersen 2005-05-13 13:32:41 EDT
In that case, I'll close this bug as RAWHIDE.
