My issue with this update:
I was running the old linux60 kernels (that aren’t supported anymore but I was unaware because I forgot to check) and when updating something went wrong with the kernels and GDM.
I was made aware of the fact today, when the screen lock activated when I was AFK for a while. The DM was throwing an error and not giving me the option to enter a password and unlock.
I rebooted and reached a tty. I logged in from there and using startx I could log in to a GUI.
I researched the forums extensively to understand what was wrong.
- Old not supported kernel still active
Solution:
I cleaned up the kernels (I am now on linux62) and but the issue was there again.
I tried a systemctl on GDM and an error occurred stating there was no GDM, I, therefore, installed and enabled GDM following this guide in the Wiki, and my laptop boots correctly and GDM works.
For some reason being on older kernels when updating deleted GDM from my system or an older version was still there active and prevented the new one to work even if I had the new latest kernel.
Note to self, always check kernels before upgrading and read the release notes so that you know what to expect.
There it is. I did remove the orphans! So in fact it was me who removed it… unwillingly. Thanks @kevin77 for this explanation on how it was magically gone.
