I finally found a solution/workaround (I can't believe it)!!! A thread on the nvnews forums discussed a similar problem. One comment suggested setting the option NoExtendedGpuCapabilitiesCheck in xorg.conf to disable mode validation (http://www.nvnews.net/vbulletin/showpost.php?p=2039336&postcount=11).
I can now use both monitors at full/native resolution :) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/727112 Title: nvidia-current does not detect hardware capabilities correctly Status in “nvidia-graphics-drivers” package in Ubuntu: Incomplete Bug description: nvidia-current is unable to use two monitors in full resolution (wuxga + full hd), one will always stay blank. looking into xorg.log, i can see something like: [ 89444.991] (WW) NVIDIA(0): Due to hardware capability constraints, disabling display [ 89444.991] (WW) NVIDIA(0): device Seiko/Epson (DFP-0) in MetaMode [ 89444.991] (WW) NVIDIA(0): "CRT-0:nvidia-auto-select@1920x1080+1920+0,DFP-0:1920x1200@1920x1200+0+0". the same configuration works with nvidia-173, so nvidia-current might not be detecting hardware capabalities correctly. nvidia-173 feels a bit slower than nvidia-current, so i'd like to use nvidia-current. my graphics card is `01:00.0 VGA compatible controller: nVidia Corporation G86M [Quadro FX 360M] (rev a1)` i'll be glad to give further information, this has bugged me for quite a while. i'm currently running natty, but i've seen this bug since nvidia-current was introduced ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: nvidia-current 270.29-0ubuntu3 ProcVersionSignature: Ubuntu 2.6.38-5.32-generic-pae 2.6.38-rc6 Uname: Linux 2.6.38-5-generic-pae i686 NonfreeKernelModules: nvidia .proc.driver.nvidia.gpus.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86 Kernel Module 270.29 Wed Feb 23 16:16:53 PST 2011 GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-3ubuntu3) Architecture: i386 CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,scale,session,unityshell] CompositorRunning: None Date: Tue Mar 1 12:34:01 2011 DistUpgraded: Yes, recently upgraded Log time: 2010-12-25 19:00:20.784814 DistroCodename: natty DistroVariant: ubuntu DkmsStatus: virtualbox-ose, 4.0.4, 2.6.38-5-generic, i686: installed virtualbox-ose, 4.0.4, 2.6.38-5-generic-pae, i686: installed nvidia-current, 270.29, 2.6.38-5-generic-pae, i686: installed GraphicsCard: nVidia Corporation G86M [Quadro FX 360M] [10de:042d] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:01ff] MachineType: Dell Inc.
