ThinkPad T500, Natty 64bit: I turned off the screensaver entirely & set the screen to sleep after 5min. Now it doesn't lock up every time, but still locks up. Often, the screen will wake up & the GUI will all be frozen.
I just tried the "Alt + SysRq + r + s + e + i + u + b" trick & it wouldn't reboot. All the steps appeared to work until the "b" for reboot. Bug 303601 might be relevant here. I don't have time right now to learn why it didn't reboot for me just now, but I'll do that next. Also, there's another key combination with "Alt + PrintScreen + r + e + i + s + u + b", which is the way I always remember it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762918 Title: Natty Screensaver freezes system after some period of inactivity -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
