Red Hat Bugzilla – Bug 450845
Fujitsu-Siemens with S3 Unichrome chip detects wrong screen resolution
Last modified: 2010-05-05 03:12:35 EDT
Description of problem:
On GDM screen and in GNOME laptop has wrong resolution detected (see the
attachement). After setting resolution in "System /
Preferences / Hardware / Screen Resolution" then in Gnome after login I see the
correct resolution but still on each GDM I see that the correct resolution is
not detected (look at the attachement).
Version-Release number of selected component (if applicable):
Steps to Reproduce:

gdm login with wrong resolution set.
Rather than a screenshot, I'd like to have the xorg conf and xorg log, please.
This can probably be worked around by setting the correct resolution in the xorg

As a workaround, in the Display SubSection of your xorg.conf, add the following
I'm afraid there's not much that can be done for this bug until some development
around the panel code happen upstream.
Sorry for my ignorance, but what do you mean by "upstream panel code"? Do you
mean that I should report this bug to upstream unichrome project? X11? Or
Sorry for not being clear. Upstream is currently working on improving the panel
code. This code is not completely stable yet, but I hope it will be in the
coming weeks. I'm following openchrome development very closely and the new code
will be in Rawhide soon after it is in openchrome subversion repository.
Actually, there is already a pre-version of this code in Rawhide, but I can't
promise it'll work. For the time being, the only possible solution to your
problem is probably to work around it.
One other possible workaround could be to use Option "PanelSize" "1024x768" in
the Device section of xorg.conf, with or without Modes "1024x768" in the
Oh, thank you.
I can live with this bug and if you need I can test the new openchorome driver
code if it will be pushed into Fedora 9 testing-updates repo. Just tell me if
you would find my feedback helpful or if you got everything under control :)
Valent, can you please give the latest rawhide package a try ?
ok, I'll try it...
It is still the same. I'll upload Xorg.0.log a bit later.
I tested xorg-x11-drv-openchrome-0.2.902-10.fc10.i386 and I still see the same issue.

I tested this laptop with Fedora 10 beta and still no change, the screen is set to much higher resolution than it really is and I have problems even login on because I see only 1/4 of the screen :(
Unfortunately, the new upstream panel code doesn't support the CN400 chipset, it's aimed at K8M890, P4M900 and CX700. I had a try at enabling the panel code for CN400, VM800 and P4M890, but the test wasn't fully successful on a VM800, so I reverted the change. You'll have to live with the old modesetting method (VBE) for now, sorry about that.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
I found this problem still exists in Fedora 11.
I had to install using text mode and a just my xorg.conf file manually.
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.

Now that F12 is branched, I'll start to add more patches to the devel branch once openchrome 0.2.904 is out (should be real soon now).
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions).
Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
[This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
