One day booting my PC I noticed that only one out of two monitors displayed the signal/data from the PC. Switching cable, ports and rebooting I realized that every of the three display ports of my trx 2080 ti were working fine but not at the same time. At maximum one port/display shows the PC's output data. Further when calling nvidia-smi I had the following result: "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."
Going to "settings"->about I found out that the Graphics are managed by "llvmpipe (LLVM 7.0, 256 bits)". Seems to be the fallback variant of the Mesa 3D graphics library when no GPU driver is available. Ubuntu 18.04.2 is currently installed on my machine.
Reinstalling the NVIDIA driver serveral times and using different methods (e.g. by execeuting run_file {NVIDIA Driver, CUDA 10.0 including driver installation}, using the graphics driver ppa from Ubuntu, .deb packages for CUDA 10.0 and CUDA 10.1 including driver installation) did not solve the problem.
After removing the old driver and re-installing the latest versions of the driver (418 and 410) I will get always the same message when executing nvidia-smi:
"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running." Further, only one monitor works while the other does not a signal.
I also tried another GTX graphic card (different model) and got the same issue.
The strange thing is, that I did not change anything on my system when problem has occurred the first time, besides some regular Ubuntu updates. Could those have been affected the NVIDIA driver?
