So, my computer froze and I had to restart it manually. Normally, this has never been a problem, but this time Mint didn't start up correctly. Everything up to and including the loading bar works correctly, but after that, instead of seeing the login screen, I see a command line asking me to do a login- this disappears after about 30 seconds, and is then replaced by a window that says Ubuntu can't detect screen setting and must start in low-graphics mode; at this point, the only way I can get to the Mint login screen is to click the configure button, then click cancel. After that, the Mint login screen shows, and I'm able to log in, although the bottom gnome toolbar is blurry. Can anyone help me fix this?
