Now it happened again. dmesg was not very verbose this time. It just says: NVRM: GPU at 0000:02:00.0 has fallen off the bus. But from /var/log/Xorg.0.log I could get these lines: [ 5371.634] (EE) NVIDIA(0): Failed to determine chip graphics capabilities [ 5371.634] (II) UnloadModule: "nvidia" [ 5371.634] (II) Unloading nvidia [ 5371.634] (II) UnloadModule: "wfb" [ 5371.634] (II) Unloading wfb [ 5371.634] (II) UnloadModule: "fb" [ 5371.634] (II) Unloading fb [ 5371.634] (EE) Screen(s) found, but none have a usable configuration.
