Public bug reported: After upgrading from Maverick to Natty (clean install, not a dist- upgrade) I've noticed that every few days my laptop's X screen stops updating.
This happens when system is left idle for certain period of time, like 20 minutes. So I turned off the screensaver, but this didn't help. I have a power management setting to put display to sleep after 15 minutes, which I am now turning off (setting to 'Never') to see if that helps. When the bug occurs: I would get back to my laptop and find it's screen blank (which is expected after a while being idle,) hit a key to wake it up and get back to where I've left. However, the screen is not updating anymore: e.g. gnome-terminal cursor doesn't blink, cpu load graph applet doesn't tick, etc. If I move the mouse, it will update the cursor position and shape (e.g. turn to beam cursor when over text input area, and back to arrow then leaving the area.) If I try to click at any point or type something on the keyboard, nothing seems to happen. A gdm restart helps to regain X w/o rebooting the system. I've looked up X, kernel and gdm logs but didn't seem to find any clues. This doesn't happen every time I wake the laptop--not even every day, but sometimes it happens 2 or 3 times a day. The laptop is running on AC power most of the time, and every time the problem occurred it was plugged into wall charger. I've been running Ubuntu since version 8.10 on this same machine and never experienced this bug before Natty.
