On Ubuntu 18.04 (64-bit)
Hello, I uninstalled my amdgpu driver along with my video card and it bricked my GNOME session - I get an endless login loop. My unity session works fine. If I try to reinstall the classic session, I get:
sudo apt install --reinstall gnome-session-flashback Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: linux-headers-4.15.0-91 linux-headers-4.15.0-91-generic linux-image-4.15.0-91-generic linux-modules-4.15.0-91-generic linux-modules-extra-4.15.0-91-generic Use 'sudo apt autoremove' to remove them. 0 upgraded, 0 newly installed, 1 reinstalled, 0 to remove and 8 not upgraded.

Setting up gnome-session-flashback (1:3.28.0-1ubuntu1.4) ... gnome-session-flashback.target is a disabled or a static unit not running, not starting it. I've installed the card again, with the exact same amdgpu-pro driver, but this error continues to persist.
Any help is appreciated!

I managed to fix it by:
sudo apt-get purge gnome-session-fallback sudo apt-get autoremove sudo apt-get autoclean sudo apt-get install --reinstall gnome-session-flashback sudo apt-get install --reinstall ubuntu-desktop Note: the penultimate command will fail again, but ignore this. I suspect that only the last command is really needed, but this is what I did as a sequence exactly.
I followed this post: How to fully remove all packages installed by 'gnome-session-fallback'?
