So I was on my dell inspiron 910 mini computer, running Hardy Heron at work. I left for a minute, came back, and a coworker had pressed a button or something, and the panel normally at the top was at the right. To fix it, I had to remove some of the objects to right click it since they were in the way. While trying to put them back on after moving it back, the computer froze and I restarted it. When restarting, I get the following message:
The GDM group 'gdm' does not exist. Please correct GDM configuration and restart GDM.
After a few minutes, a login window appears, and I try to log in, but it doesnt seem to work. It just keeps telling me my password is incorrect. Any help would be greatly appreciated. Thanks for your time everyone.
