** Description changed: I may need some help gathering necessary information for this as I am - not sure what component will be affected, I'm only guessing it is nvidea + not sure what component will be affected, I'm only guessing it is nvidia as that is the video module loaded. symptom: on changing users, only sometimes, the HDMI connected screen goes blank and the monitor hardware reports a resolution mismatch. Restarting X does not fix the problem, the only solution I've found is a hardware reboot. The monitor itself only has one resolution so it cannot be adjusted. this is a new problem, only since upgrading to 11.10 and persists in 12.04.1 xorg.conf: Section "Monitor" - Identifier "Monitor0" - VendorName "Unknown" - ModelName "FNI LCD TV" - HorizSync 15.0 - 49.0 - VertRefresh 57.0 - 63.0 - Option "DPMS" - # HorizSync source: edid, VertRefresh source: edid + Identifier "Monitor0" + VendorName "Unknown" + ModelName "FNI LCD TV" + HorizSync 15.0 - 49.0 + VertRefresh 57.0 - 63.0 + Option "DPMS" + # HorizSync source: edid, VertRefresh source: edid EndSection Section "Screen" - Identifier "Screen0" - Device "Device0" - Monitor "Monitor0" - DefaultDepth 24 - Option "TwinView" "0" - Option "metamodes" "1280x768 +0+0" - SubSection "Display" - Depth 24 - EndSubSection + Identifier "Screen0" + Device "Device0" + Monitor "Monitor0" + DefaultDepth 24 + Option "TwinView" "0" + Option "metamodes" "1280x768 +0+0" + SubSection "Display" + Depth 24 + EndSubSection EndSection Section "ServerLayout" - Identifier "Layout0" - Screen 0 "Screen0" 0 0 + Identifier "Layout0" + Screen 0 "Screen0" 0 0 # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Keyboard0" "CoreKeyboard" # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Mouse0" "CorePointer" - Option "Xinerama" "0" + Option "Xinerama" "0" EndSection Section "Device" - Identifier "Device0" - Driver "nvidia" - VendorName "NVIDIA Corporation" - BoardName "GeForce GT 220" - Option "NoLogo" "True" + Identifier "Device0" + Driver "nvidia" + VendorName "NVIDIA Corporation" + BoardName "GeForce GT 220" + Option "NoLogo" "True" EndSection Xorg.0.log report: everything looks normal booting up [ 46.951] (**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32 [ 46.951] (==) NVIDIA(0): RGB weight 888 [ 46.951] (==) NVIDIA(0): Default visual is TrueColor [ 46.951] (==) NVIDIA(0): Using gamma correction (1.0, 1.0, 1.0) [ 46.951] (**) NVIDIA(0): Option "NoLogo" "True" [ 46.951] (**) NVIDIA(0): Option "TwinView" "0" [ 46.951] (**) NVIDIA(0): Option "MetaModes" "1280x768 +0+0" [ 46.951] (**) NVIDIA(0): Enabling 2D acceleration [ 48.517] (II) NVIDIA(GPU-0): Display (FNI LCD TV (DFP-0)) does not support N VIDIA 3D Vision [ 48.517] (II) NVIDIA(GPU-0): stereo.
