The problem seems to be different since I'm not able to deterministically start my X even with above mentioned workaround.
The manually changed xorg.conf yields to the same X-window-not-working- handling. Neither trying to create a new config nor default low-graphics mode is working. A service gmd restart seems to work randomly - sometimes the screen remains black. Last dmesg output is: [ 64.086516] mtrr: no MTRR for f0000000,1000000 found After that I changed a section in my xorg.conf to: Section "Module" # Load "glx" # Load "GLcore" # Load "v4l" EndSection an rebooted. This yields to the same X-windows-not-working-screen. But now "Start ubuntu in low-graphics mode" is working.
