OS: openSUSE 12.2 x86_64 Video card: NVIDIA GeForce 6200 Graphic driver: nvidia graphic driver (x11-video-nvidiaG02-304.88-26.1.x86_64, nvidia-gfxG02-kmp-desktop-304.88_k3.4.6_2.10-25.1.x86_64, nvidia-computeG02-304.88-26.1.x86_64) Display: Samsung SyncMaster 720N Native resolution: 1280 x 1024 at 75 Hz 1:00.0 VGA compatible controller: NVIDIA Corporation NV44A [GeForce 6200] (rev a1) VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 disconnected (normal left inverted right x axis y axis)
This looks like it could be a kernel/framebuffer bug which I just saw again on Monday with a slightly newer PCI GeForce and 12.2 but Nouveau instead NVidia driver. Please beg, borrow, steal or buy a DVI cable to substitute at least long enough to see if the behavior changes. If it's the same problem I saw, there might not be any other fix or workaround short of a different gfxcard. I didn't try too hard. Instead I replaced the card, which I was only trying out anyway. It was available here to try in the first place because I had removed it from another system where it was also producing out of range black LCD screens using a VGA cable but not DVI cable.
Other things to try: remove quiet from kernel cmdline change kernel cmdline from splash=silent to splash=verbose
Hi Felix: I have deleted the nvidia proprietary driver (x11-video-nvidiaG02-304.88-26.1.x86_64, nvidia-gfxG02-kmp-desktop-304.88_k3.4.6_2.10-25.1.x86_64, nvidia-computeG02-304.88-26.1.x86_64 packages) to see how linux nv driver works. Now (after rebooting) both the graphical display and vt terminals work, that is I can switch to vt1, vt2 etc. But there is something I don't understand: lsmod does not list nv module for video:
lsmod|grep nv sata_nv
But it lists nouveau driver: lsmod|grep nouveau nouveau 845145 0 ttm 91975 1 nouveau drm_kms_helper 51053 1 nouveau drm 272559 3 nouveau,ttm,drm_kms_helper i2c_algo_bit 13414 1 nouveau mxm_wmi 13022 1 nouveau video 19401 1 nouveau wmi 19071 2 nouveau,mxm_wmi button 13907 1 nouveau Package xorg-x11-driver-video-nouveau is not installed, xf86-video-nv package is installed. glxgears works as well which is not expected with the nv driver. But a lot of Mesa packages are installed, maybe it compensates? xrandr gives:
xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 60.0* 75.0 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.0 60.0 832x624 75.0 800x600 75.0 72.0 60.0 56.0 65.0 700x525 75.0 60.0 640x512 75.0 60.0 640x480 75.0 73.0 67.0 60.0 720x400 70.0 576x432 75.0 512x384 75.0 70.0 60.0 416x312 75.0 400x300 75.0 72.0 60.0 56.0 320x240 75.0 73.0 60.0
This is openSUSE 12.2, KDE3, xorg-x11-server-7.6_1.12.3-1.41.1.x86_64, without /etx/X11/xorg.conf file. I am confused. Would be grateful if you explained what is going on. I attach the last Xorg.0.log file. Thanks, Istvan
