I am a beginner.
I had a working system with Nvidia drivers installed until some recent driver nvidia-driver-440 messed up the system.
Unfortunately, the regular gdm stopped working and I had to install lightdm.
When I execute:
nvidia-smi I get this:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
And for detecting the cards in the system, I ran this:
lspci | egrep 'VGA|3D' 00:02.0 VGA compatible controller: Intel Corporation Device 3e9b 01:00.0 VGA compatible controller: NVIDIA Corporation GP107GLM [Quadro P600 Mobile] (rev a1)
I tried installing CUDA Toolkit hoping it might help to detect my external monitor. Unfortunately, that didn’t help.
Secure-boot has been disabled in BIOS.
Also, I tried to troubleshoot by myself in getting the external monitor to work and in the process, I believe the KDE related packages also got uninstalled. I can switch to the default login session but it goes into infinite login loop with this message:
Failed to start session Also in the process of fixing the display manager, I lost Nautilus as the default file manager. I had to install a new file manager called Nemo. Other KDE based software (Kalc) have been missing from my system too. I want to avoid a clean install again, since I have a lot of data on the drive and taking backup will be a time consuming task.
I have attached the bug report with .log extension. This forum didn’t allow me to upload the original generated and gunzipped logfile named: nvidia-bug-report.log.gz
SO PLEASE RENAME BACK THE FILE WITH EXTENSION: .gz
Please let me know how I can use the external HDMInvidia-bug-report.log (100.3 KB) monitor and use Nautilus and KDE based software.
