hmm no that did not work :-\. i tried both xrandr and xvidmode for resolution change, it seems to change nothing (beside i cannot change the resolution in nvidia-settings anymore). now here is my xorg.conf: Code: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" Option "NoLogo" "true" Option "RenderAccel" "True" Option "NoRenderExtension" "False" Option "NvAGP" "0" Option "AddARGBGLXVisuals" "True" Option "AllowGLXWithComposite" "True" Option "DynamicTwinView" "False" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" SubSection "Display" Depth 24 EndSubSection EndSection
