Description David Woodhouse 2009-11-30 15:55:54 UTC

On HP6930, X runs _extremely_ slowly. Closer inspection shows that it's probing the TV output over and over again. I have this output from the kernel...

[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0
[drm] TV-20: set mode NTSC 480i 0

And Xorg.0.log contains this, over and over again.

This is the same box that oopses with 2.6.31, and other reporters of that problem have also seen this behaviour.

Comment 1 H. Peter Anvin 2009-11-30 16:16:12 UTC

Similarly, with a 2.6.31 kernel the Acer 1410 locks up when X starts unless the TV out is disabled.  The lockup seems to happen significantly quicker when equipped with 4 GB RAM.

Comment 2 Wang Zhenyu 2009-11-30 18:18:06 UTC

Originally we have quirks for this in user modesetting driver, we probably need to port it to kernel if current detect method can't help.

Comment 3 Jesse Barnes 2009-12-10 14:43:22 UTC

This one should be fixed in drm-intel-next.
