Description Stuart Fairley 2001-06-27 12:33:29 UTC
Description of Problem:
Running on an IBM ThinkPad 240, after starting X the system appears to
pause every few seconds (most noticeable when using the mouse, which just
stops moving).

How Reproducible:
Run a laptop install on a ThinkPad 240, run X, move the mouse around

Steps to Reproduce:
1.  Start X on IBM ThinkPad 240
2.  Move mouse around

Actual Results:
Mouse stops moving for a moment every few seconds (system stops

Expected Results:
System should run smoothly all the time and mouse motion should be smooth.

Additional Information:
After some investigation it appeared to be the battery applet which was
causing the problem - increasing the time between updates caused the pauses
to happen less often. Disabling the battery applet fixed the problem

Arjan, could this be kernel related?

Comment 2 Mike A. Harris 2001-06-29 21:54:11 UTC
Or more likely, a bug in the applet causing it to consume CPU and slow X
down.  Most probably not an XFree86 bug.

Comment 3 Arjan van de Ven 2001-07-02 08:46:05 UTC
Bios bug; some biosses take forever to determine batterystatus and the
battery applet then causes evil things ...

Comment 4 Stuart Fairley 2001-07-02 15:45:57 UTC
After Arjan's comment I checked the BIOS version and found there had been 14
releases since the version I had. I upgraded to the latest version (1.16) and
the applet doesn't appear to cause any degradation in performance now.
