Description Geoff Gustafson 2008-04-25 13:44:37 EDT
Description of problem:
I installed 5.2 Snapshot 7 x86_64 on a Intel Tylersburg EP / Nehalem B0 SDV. It
came up in 1024x768 according to s-c-d. But the display was oddly squished
horizontally as if it was really a widescreen resolution being displayed on my
4x3 screen. It looked bad as if the refresh was very poor as well.

I switched to 800x600 which came up fine, restarted X. Now 1024x768 is not an
option in s-c-d.

Version-Release number of selected component (if applicable):
mga driver version 1.4.2-7.el5, but not sure what component this is really in

How reproducible:
Only saw once on install so far.
Comment 1 Geoff Gustafson 2008-04-25 14:29:33 EDT
Same thing on i386. Running xclock with -geometry I've convinced myself that the
actual resolution is 1280x768.
Comment 2 Geoff Gustafson 2008-04-25 16:28:01 EDT
Same thing on Fedora 9 Preview i386, FWIW.
Comment 3 Geoff Gustafson 2008-04-25 16:31:44 EDT
Ah, sorry, on F9p s-c-d recognizes the resolution as 1360x768. Can't seem to
successfully change to lower res with s-c-d.
Comment 4 Matěj Cepl 2008-05-03 09:08:04 EDT
Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

X log after starting with no xorg.conf present

This reproduced the problem, the resolution X decided to run at was weirdly
Comment 9 Adam Jackson 2012-04-26 13:51:55 EDT
Almost certainly fixed since.
