This was the sequence I followed to update the Nvidia drivers (previously NVIDIA-SMI 430.40 Driver Version: 430.40 CUDA Version: 10.1) on my REMOTE Ubuntu 18.04 workstation: sudo apt-get purge nvidia* sudo apt-get autoremove sudo add-apt-repository ppa:graphics-drivers sudo apt-get u…

libglvnd0 is not part of the nvidia driver but an essential part of the OpenGL driver stack. So the whole desktop and graphics stack got purged. Please try just sudo apt-get install --reinstall ubuntu-desktop

Looks like you’re using a broken xorg.conf again. Please delete all xorg.conf files and use only the one I gave you.

Darn, yeah, in one of the iterations I tried after TeamViewer is detecting the workstation again I did restore the old xorg.conf just to see whether that worked. I tried with the one you gave me first though. I’ve restored that now (below), and it has improved resolution! It even detects both monito…

So now xorg and teamviewer are fine, don’t touch their config. The message “Failed to start session” points to an issue with gnome. When switching from gdm to lightdm, did you additionally install lightdm or did you remove gdm an accidentally also gnome? Please check lightdm logs.

I only did the purge commands in one of the messages above (purged nvidia, cuda, libcudnn, and libglvnd0). Did not intend to mess with gnome or to switch from gdm to lightdm. In the middle of the purge, the terminal asked me to pick a DM, and gdm was not in the list. The only one I recognized was l…

So I do that and then reboot, and everything else we’ve fixed should remain normal? (Xorg and TeamViewer configurations). I have several conda environments set up and can run various software packages to analyze data fine -it’s just visualizing the results that has become an ordeal, having to trans…

By uninstalling libglvnd already all applications using opengl have been uninstalled. Your home directory should be untouched so all things you installed using anaconda (if it resides in your home directory) should still be there. Installing ubuntu-desktop should not remove anything, just check the …

You can also use the --dry-run option for apt to check first what’s going to happen.

The conda environments are set up within my home directory, but there’s one piece of software that I did install with sudo so that it’s available system wide (this one is easy to reinstall though). TeamViewer is also installed with sudo so that it’s available to all users (occasionally other people…

[image] generix: sudo apt-get install --reinstall ubuntu-desktop Done, TeamViewer works as normal again! THANK YOU SO MUCH! Glad the hellish conditions didn’t go beyond10 days. (I wonder whether I should upgrade from Ubuntu 18 to Ubuntu 20 when I’m back in town in January…). Also, not dir…

Hard to say something about the network issue, ip4/ipv6, different subnet, router involved, checked iptables output?

You could use traceroute to check if the expected routes are taken.
