GUI Session Fails to load after updating to 20.1~git2002041930.b06469~oibaf~b
After recent system update, system freezes to a black screen with cursor and lightdm-greeter does not appear. Booting in recovery mode works. Purging ppa oibaf sudo ppa-purge ppa:oibaf/graphics-drivers
and deconfiguring mesa to Mesa 19.2.8 solves the issue temporarily, re-adding the ppa and updating results in same problem.
- Dmesg shows no error.
- i386 and amd64 both drivers are installed.
- Xorg logs show no error.
