Was looking through some old CD's, trying to find a backup I needed, clicked in an old .avi file selecting "Open with..." Mplayer - the system crashed instantly - blowing out of X and triggering a re-boot of the system.
When I tried to restart, Cinnamon (the default) GUI would not start. Mate and all the other GUI's work fine - but Cinnamon just paints the background, and then rolls out to the login prompt. Occasionally an error message box will appear directing me to look at ~/.xsession-errors a 54.2Kb file (this time, it varies by +/-4Kb or so each time I try and bring up Cinnamon) that reports my entire system is a mess and nothing is working (and nothing mentions Cinnamon, just Mate) - but pretty much everything it reports as broken is working fine for Mate, or anything else I run. I know that in the hundreds of lines there is one or two lines with the actual problem, but I don't have the experience with Cinnamon/Gnome 3 to spot it right off.
Can anyone save me having to become an expert on this subject so I can get Cinnamon, which is the first GUI I have actually been excited about since I got a NeXT back in 1988, to start up and run again! Cinnamon takes full advantage of my Nvidia A
Tried to upload the .xsession-errors file, but am told "the extension .xsession-errors is not allowed". Huh? Will be happy to upload, transmit, or cut and paste to the editor - but it's obscenely HUGE. Let me know...
