I just installed 12.04 on an old Lenovo T60 Thinkpad. I'm mostly really liking it, except several times in the last two days I've gotten into a state where all user input is rejected. The mouse moves (both from the touchpoint and touchpad) but I can't click on anything. Key presses are also ignored. All I can do is reboot. Being a Linux newbie, I have no idea of what debugging strategy I might use to try to figure out what's going on. Pretty much all ll I'm running is firefox, and this is a vanilla clean install. The lock-ups seem fairly random. One time it definitely happened when I was trying to drag a firefox window between workspaces.

I had a similar problem with several old Thinkpads.Try removing the battery. It seems that a dead battery (no longer holding charge) can cause this issue under Linux on the thinkpad.

Hey, thanks for the input. The battery seems OK. I can run on battery power for five or six hours of moderate use including wireless networking.

One other data point: I can boot into Windows XP on the same system, and I don't run into this behavior.

Just out of curiosity, if you boot into an Ubuntu Live CD do you have the same issue?

Dunno. I'll give it a shot and report back. That's a mode the original install CD I made can run in, right? I seem to remember a "try ubuntu without installing" option.

Yes "Try without installing" will boot into a live system that runs right off the cd/dvd.

I played around with the live CD for about a half hour last night. I didn't get the lock-up, but I'm not sure it's a great test, because its too slow to really use, and the timing is completely different because it keeps hitting the CD.

More testing with the live CD last night did not turn up any freezes. Someone in another thread mentioned this might be related to X windows. This is possible, since I installed Gimp.
