Bug#589348: xorg: Jerky cursor and keyboard lagging, slow rendering speed for 5-15 seconds after changing screen
Package: xorg
Version: 1:7.5+6
Severity: normal
After activating a screen the following symptoms happen (usually) less
than 10 seconds:
-the cursor is jerky
-moving a window or clicking does not seems to happen immediately
-shortcuts (ex. Alt+Tab) do not work, and typing is lagging.
This is not caused by intense disk activity, which usually freezes Xorg.
It happens even though
there's absolutely no disk activity.
Reproduce:
-login to desktop session
-Ctrl+Alt+F1 to change to a terminal (or suspend to RAM, swith to
another X session etc.)
-go back to the desktop session (Ctrl+Alt+F7, resume from suspend, etc)
-notice the lag described.
This happened in Unstable for a long time, I believe regardless of
driver version and other Xorg components.
Please ask for any other needed information.
