Today I was in a Zoom call, my mic stopped working so I rebooted my computer (sudo shutdown -r after I previously had not rebooted my computer for 7 days), and then after that looks like X no longer starts upon successful login anymore? My desktop interface no longer displays my desktop icons or anything upon successful login, it just loops right back to the LightDM login prompt after successfully logging in.
I have tried uninstalling my NVIDIA driver (460) and just using Nouveau, I have tried using gdm3 instead of lightdm, I have tried using Ubuntu (Gnome) instead of Xfce 4.12 DE, nothing seems to work. In order to get into my graphical desktop, I need to log in via TTY (crtl+alt+f1 IIRC) and then I must manually type startx as my regular user ken and then I can now see my desktop GUI with all my desktop icons, etc. I never had to do this before, though? My computer had an uptime of around 7 days before rebooting it today. Creating a new user account also did not help.
I booted at February 1, 2021 successfully, here is the uprecords proof:
37 6 days, 19:30:11 | Linux 4.15.0-135-generic Mon Feb 1 19:47:34 2021
Here is a list of automatic upgrades my automatic upgrade script has done since February 1 2021: https://pastie.io/zlzpvu.sql
Also, I have a file called core in my home, sudo file core reports the following:
core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from '/usr/lib/xorg/Xorg -core :1 -seat seat0 -auth /var/run/lightdm/root/:1 -noliste', real uid: 0, effective uid: 0, real gid: 0, effective gid: 0, execfn: '/usr/lib/xorg/Xorg', platform: 'x86_64'
Running gdb /usr/lib/xorg/Xorg $HOME/core then bt returns this:
