Description Jon Z 2009-02-25 05:03:01 UTC 
I've tried to setup Nouveau with a dual screen configuration, but I haven't been very successful doing that. I've connected two monitors to my onboard Geforce 7050  PV graphics adapter (NV44), one through DVI the other through the VGA connector. While the monitor connected through the DVI connector works fine at its native 1920x1200 resolution, I'm not able to use the other one at its native 1280x1024@60 Hz resolution. The only resolutions that work are 640x480 and 720x400. Maybe 320x240 as well, but that one is not supported by the monitor (the monitor detects a signal but tells me, that the resolution is not supported).

The system is an Arch Linux 64 Bit machine running Xorg X Server 1.5.3 on an ASRock mainboard with the Geforce 7050 PV chipset, a Athlon 4850e CPU and 8 GB of RAM.

Does the VGA screen work at the desired resolution when the DVI screen is not plugged?  If not, does the VGA screen work at the desired resolution when you add `Option "randr12" "off"' to the device section of your xorg.conf?

Please also make a new xorg.0.log with `Option "ModeDebug" "On"' added to the device section (without the randr12 option) and attach it to the bug (rafb posts expire after 24 hours and there's no guarantee someone will read the bug in that time).

Finally, if it works in single head, attach your xorg.conf in case it's a configuration issue.

No reponse from the reporter for more than a year. Closing.
If the problem still exists on current version, please reopen with new set of logs.
