New to the forum, and i will probably not post that much but i thought i may provide valueable information for other users :
So after ages i rebooted my old MSI CX720 laptop to Linux as my wife has been using this laptop with windows until recently when she got a new laptop.
Obviously i want the best and latest software so i updated Mint. I came from 18.something and went on to 19.0 when i thought i was up-to-date. I fiddled around a bit, noticed there was a MATE option which i did not have so i got it installed and played around with it. Then i noticed (While on MATE) that there was a 19.1 update available which i instantly ran.
After reboot I tried logging into MATE again just to see the screen flicker once or twice to return to the login screen. surprised i tried it again with the same result.
Tried CInnamon and that was no problem. Tried updating again > rebooted a couple of times while removing and installing mint-mate-meta but MATE would return to the login screen so that left me with Cinnamon. not that bad, but when things are broken i want to fix stuff.
browsing google for CLI troubleshooting i stumbled on a forum thread somewhere where it was encouraged to do :
Code: Select all
cat /var/log/syslog | grep fail
cat /var/log/syslog | grep mate

VINO turns out to be a remote desktop viewer from VNC or something like that.
So i tried locating org.gnome.Vino which gave me some results :
Code: Select all
locate org.gnome.Vino
cat /usr/share/glib-2.0/schemas/org.gnome.Vino.enums.xml
cat /usr/share/glib-2.0/schemas/org.gnome.Vino.gschema.xml
Locating Vino even more :
Code: Select all
Diet@DietLinuxMint19 ~ $ locate vino

using vim I removed MATE from the red line, just to notice after reboot MATE has returned. and obviously a flickering login screen.
Then i figured I had never used vino (hell, i even had never heard of the program) so i decided to remove Vino.
After :
Code: Select all
sudo apt-get autoremove vino
Although autoremove removed a lot of programs i still think that vino may not have been to happy on my installation.
