Hallo, Felix, what about an xorg.conf with a minimum configuration, i.e. disable all extensions: Section "Module" Disable "glx" Disable "dri" Disable "dri2" Disable "dbe" Disable "record" Disable "extmod" EndSection ... and then limit the display to moderate resolutions: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" "800x600" "640x480" EndSubSection EndSection It is unlikely that the problem is monitor related, but maybe you also put in Section "Device": Option "DDC" off (But then you have to provide HorizSync and VertRefresh values in the "Monitor" section.) If this works, you can step by step find out which setting kills your GPU.
