[nvidia-glx] Feisty upgrade broke a working dual monitor setup and required nvidia-glx-new to be installed to work again

Thank you for your bug report.

Djihed:
Please can you upload the following filesfrom a run where it fails:
/var/log/Xorg.0.log
Could you also upload the output of:
dpkg -l nvidia-\* | grep ii
?

Settings to needsinfo pending reply from Djihed.

X log is attached.

$ dpkg -l nvidia-\* | grep ii
ii nvidia-glx 1.0.9631+2.6.20.5-15.20 NVIDIA binary XFree86 4.x/X.Org driver
ii nvidia-kernel-common 20051028+1ubuntu7 NVIDIA binary kernel module common files

Thanks for looking into this. Let me know if you need any more info.

For the record, X runs, it just won't use both monitors, only the primary one.

Djihed:
(WW) NVIDIA(0): Option "UseDisplayDevice" requested "DFP", but no unused DFPs

The driver was complaining that you don't appear to have any monitors hooked up via DVI to your machine (thus this configuration file appears to be incorrect). Can you back up your /etc/X11/xorg.conf file and try removing the Option "UseDisplayDevice" lines?

Done that, same problem. Attaching new Xorg.0.long

Djihed:
Are things any different if you install nvidia-glx-new?

Yes they are different: it works now. Thanks Sitfofe.

Djihed:
Thank you for sticking with this bug for 4 days and replying.

Hi i happened to have the same problem and with the instalation of the nvidia-glx-new everything worked, but uppon rebooting the settings went away and everything got back to before.
Also when i let the nvida-settings write the xorg file i get windowless programs.

Thanks

Same problem here, only I had nvidia-glx-legacy installed (NVIDIA NV25, Geforce4 TI4200) and it stopped working. the X.log file said something about "no working modes", it failed to detect my two 19" screens' DDC settings (ie. refresh rates etc), and so refused to go up in 1280x1024, only offered 800x600, which wasn't a mode I configured.

I installed nvidia-glx instead, which worked right out of the box with the old config.

IMHO this is quite a critical problem, although maybe not easy to solve, since losing the GUI and installing stuff by command line isn't for the faint of heart. Maybe one could do something like https://blueprints.launchpad.net/linuxconsoletools/+spec/console-menu.

Hi Guys,
I managed to overcome the Dual-Display Twinview Problem however...
GLX /Xgl still crashes horribly...

I tried the 2.6.20-16 & 2.6.20-15 kernels with all proprietary & non-proprietary Nvidia drivers...Xgl goes to 100% CPU and dies.
So although we still have dual display, no more compiz nor beryl in the twinview config.

To Reproduce:
Stop all X instances:
/etc/init.d/xorg-common stop && /etc/init.d/gdm stop
or
/etc/init.d/xorg-common stop && /etc/init.d/kdm stop #for kubuntu
then in the console run:
export DISPLAY=:1
sudo /usr/bin/Xgl :1 -fullscreen +xinerama &
glxgears &

...after a few seconds of spinning the Gears will slow down, XGL will go to 100% CPU and a few more mouse clicks will kill the X session completly.

heres some of my system info:
lspci |grep -i nvid
01:05.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600/GeForce 6600 GT] (rev a2)

howtoforums.net:
I suspect your problem would be better asked in a separate bug report. The open source nv driver does not do accelerated 3D at all so I would not expect XGL to work with it in any shape or form. Further, on your NVIDIA card (with Ubuntu 7.04) you do not need to use XGL to use compiz etc. In the new bug report please indicate how you installed the NVIDIA binary drivers and please attach (using the web interface) your /var/log/Xorg.0.log , /etc/X11/xorg.conf along with the output of grep NVRM /var/log/messages .

Is this symptom still reproducible in 8.10 beta?
