From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: Display behaves erratically after returning from suspend. For example, clicking on main menu will not reveal pulldown menu unless mouse moves over it. Also, screen saver kicks in even though mouse was in use. Switching between virtual desktops does not work. Restaring X does not fix the problem. Problem started recenlty, after applying updates, but not sure which one. Rebooting fixes the problem. Version-Release number of selected component (if applicable): XFree86-4.3.0-2.90.43, 2.4.20-20.9 How reproducible: Always Steps to Reproduce: 1.Suspend 2.Resume 3.Try to use X Actual Results: X behaves erratically Expected Results: X should behave normally Additional info: I use Cisco's Aironet 350 wireless card.
Update: I think I found the problem. the video memory was set incorrectly to 64MB. Changing it to 32MB seems to have fixed the problem. Steps to correct: - From main menu select System Settings->Display->Advanced - Select Configure and set custom memory size to 32MB. You will need to restart X and perhaps reboot the machine.
In general, you should never set the memory size. The video drivers autodetect the proper amount of memory on almost all hardware with very few exceptions, and specifying the memory can cause problems in particular if you get it wrong. Thanks for the update, setting status to "NOTABUG".
