OS: Kubuntu 19.10 (earlier versions’ installers end in a unusable state from garbled X server output)
(OpenSuse 15 Leap will install beautifully but upon startx, the X server shows garbled graphics, even in recovery mode, leaving the installation unusable.)
nvidia-settings says this system is ineligible for the NVidia Prime switch to Intel graphics. The mobo has integrated VGA graphics but the BIOS has no selection to select them if a card is installed. So one would need to remove the RTX400 card to get Intel graphics, AFAIK.)
This a dual boot machine; the graphics work well in Windows 10 without incident, as well as with with the nouveau open-source driver in Linux.
Note that the display port “1” is covered by part of the case so the cable is plugged into display port “2”. (Just in case that may be affecting anything.)
The symptoms are that the X server freezes completely and nvidia-smi says something akin to “the device has fallen off the bus”. (Please see the end of my log file ‘nvidia-driver.log’). Also find the ‘nvidia-bug-report.log’ attached. I wrote a script that runs nvidia-smi every five seconds and runs the crash report if smi says the GPU is missing.
The computer and RTX4000 card were selected to work together for high-performance computing using OpenCV with CUDA. But in a Linux platform.
It’s a six-core Intel® Xeon® E-2276ME CPU @ 2.80GHz, on a Adlink motherboard.
The issue occurs with the proprietary nvidia-drivers-430 -435, and -440. It does not happen with the nouveau driver. But the nouveau driver does not support the resolution of the monitor I happen to have attached. Additionally, the nouveau driver cannot be a fallback solution over the long term because we need to have CUDA working on this machine.
Thank you for your help.
