[Nouveau] Problems with dual head on NVidia Quadro NVS 295
Hello, I'm having problems configuring the dual-head display using an NVidia Quadro NVS 295 display card. It uses two identical LCD monitors (model HP LP2475w), connected using DP cables. If I connect one single monitor (either to the DP-1 or to the DP-2 output), the desktop shows up correctly. If I connect both monitors, only the left monitor shows the image, and the desktop is extended as if the second monitor were showing something. But the right monitor remains blank. I am using OpenSUSE 11.3, with the nouveau drivers included in its kernel (kernel version 2.6.34). The relevant parts of xorg.conf.d are: Section "Device" Identifier "Default Device" Option "SWcursor" "true" Option "monitor-DP-1" "LeftMonitor" Option "monitor-DP-2" "RightMonitor" EndSection Section "Monitor" Identifier "LeftMonitor" Option "PreferredMode" "1920x1200" EndSection Section "Monitor" Identifier "RightMonitor" Option "RightOf" "LeftMonitor" Option "PreferredMode" "1920x1200" EndSection Section "Screen" Identifier "Default Screen" Device "Default Device" Monitor "LeftMonitor" DefaultDepth 24 SubSection "Display" Depth 24 Virtual 3840 1200 EndSubSection EndSection Section "ServerLayout" Identifier "Layout0" Screen 0 "Default Screen" 0 0 EndSection Note that I had to set the mouse cursor to software rendering because it was not showing up at all when using hardware rendering (cursor was entirely invisible but the mouse was operational). The output of the "xrandr" command is: Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192 DP-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 546mm x 352mm 1920x1200 60.0*+ 59.9 1920x1080 60.0 1600x1200 60.0 1680x1050 60.0 1600x1000 60.0 1280x1024 75.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DP-2 connected 1920x1200+1920+0 (normal left inverted right x axis y axis) 546mm x 352mm 1920x1200 60.0*+ 59.9 1600x1200 60.0 1680x1050 60.0 1600x1000 60.0 1280x1024 75.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 I have also attached my Xorg.0.log file.

Using gentoo and I tested the kernels 2.6.34 2.6.35 and the 2.6.36_rc nothing changed. Until now I had the two screens connected via a DVI-to-VGA adapter and there was another problem, there was some static on the second screen, but the nvidia proprietary driver did the same thing. -------------- next part -------------- A non-text attachment was scrubbed...

But the right monitor remains blank.This is expected. Nouveau can't fully program a native DP output on its own yet, and relies on assistance from the video BIOS. As such, only displays which have previously been initialised by the VBIOS will work. Ben.> > I am using OpenSUSE 11.3, with the nouveau drivers included in its > kernel (kernel version 2.6.34).
