Resolution problems when default is not used (for example in some fullscreen games)

[pacho2]

After updating to 169.09 drivers from 100.14.19 I have problems with my monitor for displaying games in 800x600 fullscreen mode

My monitor is a Samsung SyncMaster 910MP, it uses 1280x1024 as default resolution. When I start a game (like enemy-territory, pingus, extreme-tuxracer...) in 800x600 resolution, monitor blames that a bad resolution is being used, and monitor preferences say that 1600x1200 is being used

My nvidia card is:
01:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)

And I am under Gentoo Linux

Thanks a lot

nvidia-bugreport added

Also same problem with 640x480 games. Monitor is really set to 1280x960 :-/

I have added nvidia-bugreport

Also 169.07 is affected (but 100.14.19 works ok)

100.14.23 works fine too

I experience this problem as well with 169.09.

I think the automatic mode selection is choosing refresh rates that are too high. In nvidia-settings Display Configuration, the refresh rate drop downs for many modes under 1024x768 contain "DoubleScan" modes of 120 or 130 Hz above the more reasonable modes. If I set any non-Auto, non-DoubleScan refresh rate through nvidia-settings, the low-resolution modes work fine.

Attached nvidia-bug-report.log, and edid.bin exported from one of my two identical monitors exported via nvidia-settings.

Hi, situation is different for 169.12, but not fixed.

1024x768 modes don't report DoubleScan modes, but 800x600 still has 65 Hz (DoubleScan) and 60 Hz (DoubleScan) refresh rates.

896x672 (which is a weird resolution, i think) is the largest res with one of these modes, and it only has one refresh rate: 60 Hz (DoubleScan)

All modes 800x600 and below have DoubleScan refresh rates, all of which have only DoubleScan refresh rates, except 640x480.

Nothing?

I still have to use 100.14.19 and it no longer builds with kernel-2.6.25 :'(

Thanks

Well, now the situation is becoming dramatic. There is thousands of ubuntu users, owning a nvidia card, which cannot anymore play their games ! Ubuntu 8.04 has the 169.12 drivers implemented, and the issue is debated on all forums.

Is any nvidia dev willing to answer to these people?

In the Device section:

Option "ModeValidation" "NoXServerModes"

That's in a thread somewhere in here. It fixed my ability to have games switch to various resolutions and use the correct refresh rate.

Note that nvidia-settings needs DynamicTwinView to be left alone (not specified) for the display area tab to function. Folks without dual-monitors can, if they wish, do:

Option "DynamicTwinView" "Disabled"

That'll get the refresh rates to show up properly and be detected in stuff like Compiz Config Settings Manager and KDE's KRandR Tray. By default, with it enabled, we need to uncheck Detect Refresh Rate in ccsm and specify the refresh rate you want in there (use the slider). With DynamicTwinView disabled, ccsm can auto-detect the correct rate.

Other than that it's only cosmetic. I leave it enabled as I don't care what RandR shows as the refresh rate as long as it's set properly. But in 169.12 drivers we do need that NoXServerModes in Option ModeValidation for correct refresh rates to be applied. Not sure why, but we do. Seems to me that's a bug as we shouldn't need to turn off stuff like that manually in xorg.conf. It's supposed to work automatically.
