Public bug reported: After the upgrade to Lucid, my laptop does no longer resume from suspend.
Whenever I start a suspend cycle, the machine seems to suspend without trouble (at least it seems to go to sleep and reports no error). When I press the power button to wake it up, I see some disk activity, the power LED is lit but the screen remains blank and I must end up keeping pressed the power button to shut down. I use the 'nvidia driver', but I've been able to reproduce it with the 'nv' driver as well. As for the questions on https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume: * I've got o encrypted swap * The machine never wakes up * Reproducible every time, I've tested it about 10 times by either calling Suspend... from the GUI, by letting the machine suspend on inactivity and by using 'sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend"' * Suspend and resume worked fine in Karmic * I do not end up with flashing caps-lock * This seems to be a regression from Karmic on this particular machine, where the suspend/resume process had worked without trouble Suspending from text mode I did not get any error messages, either. I also tried https://wiki.ubuntu.com/DebuggingKernelSuspend, but the hash did not seem to match any device, here are the relevant lines: [ 0.570639] Magic number: 0:202:348 [ 0.570641] hash matches /build/buildd/linux-2.6.32/drivers/base/power/main.c:430 Let me know if you need more info.
