Public bug reported: Hi! I am using Xubuntu 11.10 x86-64, German Localization. When I close the screen flap of my Acer TravelMate 5740G Notebook the system goes to sleep as it is supposed to (which didn't work under 11.04), but when I reopen it the wake-up fails: I get the login screen and can enter my password. But instead of coming back to the desktop then I get a black screen and the system freezes: It doesn't respond to any type of input anymore. I have to reboot the system after forcefully shutting it down (pressing power off for 5 seconds). This problem is reproduceable and occurs since I upgraded to Oneiric. Under 11.04 the system failed to fall asleep at all.
