I didn't think that SELinux was the problem. But for the purposes of
troubleshooting, I turned it off - though it had absolutely no
effect. This isn't a server nor is it really used for anything
important at the moment, so I'm unconcerned.
The problem is that, I can't make any progress in resolving these
problems. It seems to not be the player per se - VLC, Xine and
MPlayer all segfault when trying to output this resolution via
XVideo. This suggests it's a problem with X. Apparently, the only
thing I can do is debug with gdb and builds of X and VLC with
debugging enabled.
But I don't know how to properly build RPMs with debugging turned on.
I'm fairly new to RPM package management. I really don't want to try
and hand build X and VLC with debugging. Then I would have to remove
the old X and VLC and replace it with the freshly built version. Then
somehow I would want to remove the debugging versions and install the
proper versions again. Sounds like a mess to me.
All of this is why I have a love-hate relationship with Linux. I
don't have unlimited time and these little problems appear and
require immense amounts of time and energy to resolve. I could have
installed FC5 ten times over with the amount of time I've spent
battling this graphics card - and it still doesn't work right. And I
specifically bought a board with Intel graphics because the drivers
were open source.
