Red Hat Bugzilla – Bug 102036
graphical login sometimes has screen moving instead of pointer
Last modified: 2007-04-18 12:56:45 EDT
Description of problem:
When logging into KDE with KDM, sometimes the mouse pointer stays in the top
left corner and the screen moves around instead, when moving the mouse. The
parts of the screen that scroll off the edge wrap around to the other side. Once
logged in, KDE starts up with no problems. Usually happens when I log out to relog.
Don't know if this is a problem with xfree, KDE or kdm.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Log into KDE using KDM
2.or log out, then log in as another user
Actual Results: Mouse pointer stays locked in top left corner. Screen moves
around with mouse instead. Pointer is actually in the correct position relative
the the moved screen. (ie screen move in opposite direction to mouse)
Expected Results: Mouse pointer should move.

attach your X server log file and config file to the bug report using the
Also, after attaching the files, try using the option "swcursor" in the
Device section of the config file to test if my assumption is true. We
can troubleshoot further after that.

Sorry for delay. HD crashed. Just re-installed.
Also, using SWCursor does inhibit the bug.
