nvidia-settings no longer changes screen mode

[Rocko]

Binary package hint: nvidia-settings

The latest nvidia-settings in Jaunty can no longer change screen modes.

When X starts, xorg.conf (attached) is configured to display the laptop screen and an external monitor side-by-side.

When I run nvidia-settings and try to change the external monitor to either be disabled or to be a clone or the laptop screen, I just get the error:

"Failed to set MetaMode (1) 'DFP-0: nvidia-auto-select@1680x1050 +0+0 (Mode 1680x1050, id: 51) on X screen 0"

or

"Failed to set MetaMode (1) 'DFP-0: nvidia-auto-select@1680x1050 +0+0, DFP-1: nvidia-auto-select @1680x1050 +0+0 (Mode 1680x1050, id: 52) on X screen 0."

nvidia-settings (for driver 180.22 or 173.14.12) using the same xorg.conf file work fine in Intrepid and Hardy.

Running sudo nvidia-xconfig does not fix the problem.

Confirmed on my Thinkpad T61p with Jaunty, and:

nvidia-173-kernel-source (173.14.16-0ubuntu1)
nvidia-173-modaliases (173.14.16-0ubuntu1)
nvidia-180-libvdpau (180.27-0ubuntu1)
nvidia-180-modaliases (180.27-0ubuntu1)
nvidia-71-modaliases (71.86.08-0ubuntu1)
nvidia-96-modaliases (96.43.10-0ubuntu1)
nvidia-common (0.2.6)
nvidia-glx-173 (173.14.16-0ubuntu1)
nvidia-glx-180 (180.27-0ubuntu1)
nvidia-settings (180.25-0ubuntu1)

xorg.conf is a copy of xorg.conf.failsafe, with 'Driver "nvidia"' as the only change.

Thanks for reporting this. I tracked this down to a regression in the X server caused by commit 56f6fb [randr: Avoid re-querying the configuration on everything but GetScreenResources]. The problem is that the DIX and DDX get out of sync with respect to the mode pool, so the DDX knows about the new configuration but the DIX doesn't. I started a thread about it on the X.org mailing list, so hopefully it'll get resolved before 1.6 comes out. In the meantime, you can work around the problem by hitting the apply button, dismissing the failure dialog, running "xrandr" in a terminal window, and then hitting the apply button again.

Workaround didn't work... It results either in reboot or distorted compiz windows. One time everything was good till I started firefox - then in hanged...

[Rocko (rockorequin)]

The workaround has so far worked for me, thanks.

Confirmed on 8800 gts. Not sure if this has anything to do with it, but video playback "lags" after upgrade to 9.04

[agren (andreas-gren)]

Works here too. Ti4200, driver 96. Cheers!

Fixed upstream:

commit 660c2a7d4c6cb52fd0992e9d2008a24805dc8c02
Author: Aaron Plattner <email address hidden>
Date: Thu Feb 12 18:27:48 2009 -0800

    Query the DDX in ProcRRGetScreenInfo.

    This is the RandR 1.1 version of GetScreenResources and needs to re-query the
    DDX to see if the mode pool changed.

    Fixes Launchpad bug #325115.

Thanks, Aaron. And thank you for the work-around. T61 with nvidia 180.29.
