Description Tom Horsley 2006-10-30 20:22:30 EST
Description of problem:

See https://bugs.freedesktop.org/show_bug.cgi?id=8790 for all the
gory details.

Version-Release number of selected component (if applicable):


How reproducible:

Random, but so frequent as to be unuseable.

Steps to Reproduce:
1. Try to use radeon driver with Westinghouse LVM-42w2 monitor at
native 1920x1080 resolution.
2. Watch display turn on and off.
Actual results:

At random, the display turns off, then turns back on, then turns off,
etc. Cycle time ranges from a fraction of a second to sometimes
stabalizing and staying on. Even if it is in a stable mode, if you
turn the monitor off and come back later, or let the screen power saver
kick in, you are likely to see the unstable operation again when you
turn monitor back on.

Expected results:

Nice stable picture like I had in Fedora Core 5 with the xorg 7.0
release on x86_64.

Additional info:

The main new piece of information that led me to submit this as a fedora
bug (instead of sticking with xorg) is that (so far - knock on wood), the
i686 version of Fedora Core 6 has been running on the same hardware with
a rock solid display. This leads to lots of wild conjectures like x86_64
build problem, or compiler problem, or 64 bit porting problem in the code.
Since some of those conjectures fall in the fedora domain, I decided to
add this fedora bug.

I'll update the info in the xorg bug if the flickering crops up in the
i686 version.

Apparently you forgot to add this promised information and I suspect that this
all should be UPSTREAM bug. Correct me if I am wrong, but for now, I am closing
this as an upstream problem.
