Description of problem:
With a Matrox G400, the display is often (though not always) garbled on X
startup (basically, the display is split in 3 parts horizontally, all of which
display what should be on the screen).
Pressing Ctrl-Alt-+ and Ctrl-Alt-- gets the display into a sane state - looks
like some initialization code is wrong.
Happens about 80% of the time at 1600x1200, 16bpp
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. On a box with a Matrox G400 AGP card, startx
Actual Results: garbled display about 80% of the time
Expected Results: working display
Details of the card:
Matrox MGA G400 AGP revision 4, 16 MB SGRAM, PCI ID 102b:0525, Subsystem
Intel 440BX chipset
Please attach your xfree log and config files so this can be better
diagnosed. Should this be closed since Bero isn't following Red Hat now or
still want to troubleshoot it?
I haven't tried to reproduce yet, since it is low priority only reported
by one person, but when I do my next G400 brouhaha, I'll probably test
it, so it's ok to keep open until I've tested it or someone else can.
If I can't reproduce it then, I'll reassign it to bero for laughs. ;o)
He'd probably get a kick out of that. ;o)
We believe this issue to be resolved in our currently shipping
OS releases. Please upgrade to Fedora Core 2 or later, and if this
issue turns out to still be reproduceable, please file a bug report
in the X.Org bugzilla located at http://bugs.freedesktop.org in the
Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes
that become available for consideration in future updates.
