dual monitors not working on upgrade to karmic

Same exact issue here with GeForce 8400 GS

Workaround: switching to nvidia 173 driver in jockey fixes the issue.

Note: Manually downloading and installing the latest driver from nvidia (190.42) does NOT fix the issue.

Thanks Maxim, that fix works for me too.

I have same issue, GeForce 8600 GT + Samsung 2232BW + TV Samsung 32", it used to work on jaunty simply setting twinview and I had both monitor working. Now with the 18x driver the TV get blank and with the 173 driver any video that I play fills both the screens instead of filling just the screen it belongs.

I've tried removing the xorg.conf and setting it with nvidia-xconfig.

Same problem not solved by driver 173 on Karmic; second monitor blank with GeForce 8400GS. Have tried Nvidia drivers 173, 185 and 190. Worked fine on Ubuntu 8.10 with same xorg.conf file.

So... Does this work in Lynx?

I can only get it to work with the 173 drivers, which is a bit of a step backwards really. With the 185/190 drivers I can not overcome the widely experienced 'black screen' issue which seems to be something to do with Plymouth. Anyone else any better luck?

Tim

OK, managed to get it working with lucid. Needed information from this thread: http://70.87.46.147/vbulletin/showthread.php?p=2252094

The important bit was using 'connectedmonitors' only once.

My xorg.conf now looks like:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildmeister@builder58) Thu Apr 22 20:36:15 PDT 2010

Thanks, Tim.

Just upgraded to Lucid, but, unfortunately, was unable to get two monitors working with 180/190 drivers, even with hell of a tweaking, using your config and the link you provided, so I'm stuck with 173 for like, forever, I guess, since nobody else cares about this bug.

I'm sorry to hear that. It is very frustrating. Can you post your tweaked xorg.conf and information from /var/log/Xorg.0.log after booting up? This might pinpoint where the problem is.

Tim, thanks for you concern, but the machine in question is my $work machine so the time available to play with it is somewhat limited (ironically, this is why I've chosen Ubuntu in the first place). It works OK now with 173, so I'm going to stick with it for sometime...

I have Lucid amd64 with Geforce 9300 GS. A monitor in VGA plug and a TV in S-video plug.

With driver 173.14.22 works fine. nvidia-setting show the two screens, monitor and tv:

But with "current" driver (195.36.24), nvidia-settings only detect the monitor on VGA plug:

I try this: http://70.87.46.147/vbulletin/showthread.php?p=2252094
and to many xorg config, but don't work.

I stick with 173 too :(
