Default Re: X slowing down, and locking up with NVRM Messages on Quadro NVS140M

Section "Monitor"
Identifier "Generic Monitor"
ModeLine "1280x720_60" 74.5 1280 1336 1472 1664 720 721 724 746 -hsync +vsync
ModeLine "ATSC-720-60p" 74.16 1280 1320 1376 1648 720 722 728 750
Option "DPMS"
EndSection

From the bug report xorg.conf file....do you think there could be some sort of vsync issue causing this? Do you want me to try to reproduce with opengl vsync off in 1280x720?

So at this point, you've determined that the instability is only triggered with __GL_SYNC_TO_VBLANK turned on, while running a fullscreen application using your "1280x720_60" modeline?

If so, yes, I'd be curious whether disabling __GL_SYNC_TO_VBLANK has any impact.

Also, how did you obtain those custom modelines?

I got them from the internet or a modeline generator.
The drivers don't detect 1280x720 as a mode without them, the windows drivers do, and 1280x720 works w/ this modeline and ignoring bits of EDID as shown in the bug report.


I have to head to work, I'll be able to test this in about an hour and a half.

If that mode isn't a native mode from the EDID, then I'd have doubts on whether it would produce optimal results. Granted, you shouldn't be experiencing instability, however at the same time its not really a configuration that is expected to work well.

Is there a reason why you're not using the native modes as defined in the EDID of the DFP?

Yeah, my projector runs in 1280x720, and I generally run clone across both displays. The windows drivers have 1280x720 listed for my laptop's lcd panel.


Also, I tested with vsync disabled and enabled, it doesn't matter, it still happens. I also was able to reproduce this pretty much every time in 1024x768 as well...I still have not been able to reproduce in 1440x900.

Interestingly, once this happens, and I kill -9 the program that causes it several times and repeat it locking with the XID messages, it won't happen again until I reboot my PC. I believe it holds the ability to not lock up fullscreening gl apps through a suspend, but X slows down due to the known issue so I avoid suspending in general.

What do the NVRM: XiD (0001:00):37, CMDre 00000001 00000080 00000000 00000000 5 00000009 messages mean, anyway?
