 Posted: Fri Oct 26, 2007 9:38 pm Post subject: Flickering in X on a TV |
 |
|
I have a machine running MythTV connected to a TV via the TV-out on the nvidia 5200FX gfx card. At some point in the last couple of months X has slowed down its refresh rate or something, because although glxgears still returns the same results I now get visible flickering watching dvds in xine or (less noticeably) in MythTV. I tried writing an interlaced ModeLine for X but it didn't make any difference.
I'm wondering what other things I could check for this.
Relevant snippets from files, XOrg.0.log

This is XOrg server 1.3, nvidia drivers 100.14.11 (release after has a XV bug), 2.6.22 kernel (CONFIG_HZ_250=y) on a 64bit P4-EE. I don't want to spam with information at this point so request anything else relevant. I might nip back and try lowering from 24bit to 16. Even firefox can demonstrate the flickering so I don't think it's an application thing or a "use xvmc" type problem.
Should I try again with an interlaced modeline? |
