Schlechte Bildschirmauflösung auf Ubuntu16 (im UEFI-Modus installiert); GTX 1080TI auf einem Supermicro-Motherboard

Erstens konnte ich den nvidia-Treiber nicht von ppa installieren, da dies zu einer Anmeldeschleife führte. Ich musste die .run-Datei mit der Option --no-opengl * verwenden, wobei im TTY-Modus die folgende Befehlszeile verwendet wurde:

$ sudo ./cuda_9.2.148_396.37_linux.run --no-opengl-libs 

Dies scheint den nvidia-Treiber richtig zu installieren. Wenn ich einen der von der Ausführungsdatei installierten Beispielcodes verwende, erhalte ich Folgendes:

sudo ./bandwidthTest  [CUDA Bandwidth Test] - Starting... Running on...  Device 0: GeForce GTX 1080 Ti Quick Mode  Host to Device Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 12040.7  Device to Host Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 12875.9  Device to Device Bandwidth, 1 Device(s) PINNED Memory Transfers Transfer Size (Bytes) Bandwidth(MB/s) 33554432 347433.7  Result = PASS  NOTE: The CUDA Samples are not meant for performance measurements. Results may vary when GPU Boost is enabled. 

Hier finden Sie Informationen zu den beiden auf meinem Computer installierten GPUs

Ich habe jedoch eine sehr schlechte Auflösung, obwohl ich versucht habe, die xorg.confDatei, die ich hier poste, "abzuspielen"

Ich verstehe auch

Irgendeine Idee zum Problem? Benutze ich eine falsche BusID in der obigen Datei?
