Description of problem:
New installation of FC2 with Matrox G200 with 8MB and Viewsonic p815
but only options in system-config-display are 640x480 and 800x600. I
know it will do 1600x1200 and 1280x1024 since I was using this same
hardware on RH9. If i manually change the xorg.conf file to add
1280x1024 and relogin it works. I think system-config-display should
do a better job.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install FC2 with matrox g200 and viewsonic 9815
2. firstboot setup shows only limited options -> choose 800x600
3. system-config-display also shows limited options
4. modify /etc/X11/xorg.conf to add 1280x1024 mode.
5. log out and log in
6. display now at 1280x1024
What is the output of running (as root)
kudzu -p -b ddc
kudzu -p -b ddc output is:
desc: "Matrox MGA-G200"
desc: "ViewSonic P815"
We're only getting 2MB of memory indicated from DDC probing not the
8MB on the card. This is why we don't show the higher resolution options.
Just for completeness can you attach the generated xorg.conf (backing
your one up) and paste in a comment with the output of:
system-config-display --verbose --reconfig --noui
I'll try and investigate why this might occur
Command fails as follows:
[root@curlyjoe root]# system-config-display --verbose --reconfig --noui
Traceback (most recent call last):
File "/usr/share/system-config-display/xconf.py", line 412, in ?

Not good. What version of s-c-display are you running there? I'll
verify that seperately and try and get an update out.
Can you update to the system-config-display in rawhide please (just
that package should be fine), and try to rerun the above.
FC2 RPM package:
Where's the rawhide package?
Created attachment 103515 [details]

Trying with card: Matrox Millennium G200
Backing up /etc/X11/xorg.conf to /etc/X11/xorg.conf.backup

Creating /etc/X11/X symlink
Bill, any idea why we might get back less memory than is on the card
via ddc probing?
I thought at one point all Matrox cards returned 2MB. :/
Thanks to the above comment it sounded like a bug in the Matrox
firmware. I found a bios update on the Matrox site and installed it.
That has fixed the problem. Thank you.
