Ubuntu login circle: type userid+p/w, wait a few seconds, returns to login prompt
I was working on my .profile; it worked fine in an xterm. Rebooted. Now I can't get past the login screen. Accepts my userid&password, blinks a bit, then returns to the login screen. The only other "user" is guest, which apparently is useless for su. I'm sure that if I could disable my .profile (ie. move it, etc), I'd have it working again. Ideas?
