I am running Mint 3.1 with Nvidia driver. For some odd reason, my screen resolution changed from 1680x1050 to 1024x768. I used the Nvidia settings to change it back to 1680x1050, and all works well...until I log out. then upon next login, i am right back to 1024 resolution. Yes, i have checked /etc/X11/xorg.conf and the resolution is set for 1680x1050. That in itself is odd, but even more so...every other user logs in with the correct resolution. I am the only one it does this to. I am the SUDO user.
