Am 23. August 2016 habe ich über das Standardpaketverwaltungssystem von Ubuntu ein Nvidia-Paketupdate erhalten.
Nach diesem Update funktionierte das X-Windows-System nicht mehr.
ABER - der Reihe nach:
Verwendete Hardware:
uname -a
Linux studio16 4.2.0-42-lowlatency #49-Ubuntu SMP PREEMPT Tue Jun 28 23:12:17 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Das Hauptproblem:
part of /var/log/kern.log:
NVRM: API mismatch: the client has the version 352.99, but
NVRM: this kernel module has the version 352.93. Please
NVRM: make sur that this kernel module and all NVIDIA driver
NVRM: components have the same version.
NVRM: nvidia_frontend_ioctl: minor 255, module->ioctl failed, error -22
Für mich bedeutete dies: Die Installation war nicht in der Lage, den gesamten alten Code – insbesondere das Kernelmodul – zu bereinigen, damit er mit der neuen Version 352.99 funktioniert.
Also habe ich alle CUDA- und NVIDIA-Pakete bereinigt und NUR NVIDIA installiert:
dpkg --list | fgrep nvidia
ii nvidia-352 352.99-0ubuntu1 amd64 NVIDIA binary driver - version 352.99
ii nvidia-opencl-icd-352 352.99-0ubuntu1 amd64 NVIDIA OpenCL ICD
ii nvidia-prime 0.8.1 amd64 Tools to enable NVIDIA's Prime
ii nvidia-settings 352.99-0ubuntu1 amd64 Tool for configureing the NVIDIA graphics driver
Es gibt zusätzliche Pakete mit 352,99 wie:
ii libcuda1-352 352.99-0ubuntu1 amd64 NVIDIA CUDA runtime library
ii libxnvctrl0 352.99-0ubuntu1 amd64 NV-CONTROL X extension (runtime library)
In dieser Konfiguration bekomme ich
nvidia: module license 'NVIDIA' taints kernel.
nvidia: module verification failed: signature and/or required key missing - tainting kernel
in /var/log/kern.log.
Anschließend werden nur noch Meldungen dieses Typs aufgezeichnet:
NVRM: RmInitAdapter failed! (0x2d:0x63:1406)
NVRM: rm_init_adapter failed for device bearing minor number 0
NVRM: nvidia_frontend_open: minor 0, module->open() failed, error -5
Was ist das Problem, dass die Installation des Pakets nicht ordnungsgemäß durchgeführt werden kann?

Lassen Sie uns nun das Problem mit weiteren Informationen analysieren:
Welche Paketaktivität gab es am 23. August?
Ein Blick in /var/log/apt/term.log

Liegt ein Problem vor aufgrund von:
Stopping nvidia-persistenced^M
nvidia-persistenced: Kein Prozess gefunden^M
Als Ergebnis:
Der NVIDIA-Grafiktreiber kann NICHT geladen werden.
... fällige Teile des Kernels werden nicht aktualisiert – es wird das alte Kernelmodul 352.93 verwendet.
