Description of problem:
My custom xorg.conf ensures the DELL-recommended refresh rate, which
is lower than the default. It's attached and it works just fine.
Rerunning system-config-display (just out of curiosity) resulted in
the attached failure. I guess it just fails to parse my file
properly, i.e. some python scripts are broken or something.
If I remove xorg.conf, it works.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. add a custom Mode to Monitor section in xorg.conf
2. rerun system-config-display
Actual Results: Failure/crash
Expected Results: Either backup to xorg.conf.bak and continue
parsing out what is necessary, or gracefully exit with a warning.
I added Mode to Monitor section to override the default mode order
from the highest down. DELL 1703FP prefers 1280x1024@60Hz over
allowed 1280x1024@75Hz. Hence, I need my xorg.conf.

xorg.conf using UseModes
OK we assume that you use mode of the form of 1280x1024 rather than arbitrary
strings. We need to fixup it barfing, we also need to fix it so that if we
lookup modes and get the resolution info rather than assuming it's in the name.
A workaround may be to use a Modes section (using resolution with Identifier
"Optimum" and UseModes Optimum. Does the attache dxorg.conf work for you - it
may need some tweaking, but it should override the default 1280x1024 mode for
There should be no quotation marks in the ModeLine, ie, +HSync
instead of "+Hsync". It works then.
Using "1280x1024" string overrides the whole set of default modes,
effectively killing off 75Hz completely. You have to also add 75Hz
ModeLine in the Modes section after 60Hz to revive it. Using
"Optimum", we do not change default resolutions but rather just move
60Hz ahead of 75Hz effectively. Therefore I still prefer using custom
I can understand that. I need to fix s-c-display to deal with this
though. I was just suggesting a work around off the top of my head
until I can release an update which will handle custom names correctly.
Thanks for the feedback
On a side note (worthy of a separate bugreport), shouldn't Xorg-x11
pick up the correct optimum resolution itself without customizing
xorg.conf? After all Dell monitor communicates it via ddc. For
example, read-edid-1.4.1 recognizes the optimum resolution. Why can't
Xorg do the same? This whould spare us a lot of trouble, and custom
Mode strings could be just ignored by system-config-display.
