I have the same problem on a new Thinkpad T40 laptop -- sometimes on unsuspend, I get to see the cursor for a second or so, and then it vanishes and the laptop goes back to sleep. It's not easy to reproduce -- the first time I managed to reproduce it while acpi_listen was running was today after a week of occasional trying -- but it does occur quite regularly. Relevant features:
* Suspend was with a power cable plugged in and batteries fully charged; unsuspend was on battery power 45 mins later. * The wireless network changed between the suspend and unsuspend locations: on the second (successful) resume attempt, I got a dialog saying that the authentication credentials had been forgotten for the new wireless network (which I've used many times before) * This laptop has two batteries, which I've noticed has confused Ubuntu before (I get "critically low battery" warnings when battery #1 is near empty, even though battery #2 is full) I think this may be related to bug #31935, but was urged to submit a new report rather than reopen that one... this one seems to be such a new bug on the same issue. I'll attach an acpi_listen log from this double- unsuspend in a moment. -- Laptop automatically suspends right after resume https://bugs.launchpad.net/bugs/492649 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
