Very Computer

Hello Linux people,

I have the problem (on a 486DX2/80 SuSE5.0) that under X11, when
running CPU intensive applications like gcc, the mouse cursor is
jumping over large distances if the mouse is moved a very little
amount. This means that moving windows/resizing windows etc is only
possible with a little bit of luck (at least if the target position
should should be determinant). I have the feeling that it might be an
interrupt problem, an interrupt request which does not get
acknowledged fast enough because this error does only appear when
there's no idle time on the CPU, but I'm not sure. Does anyone know a
solution?

Thanks for any hints and answers,

 -Rainer

Greetings,

I had the same problem on my 486DX2/66 with Slackware.

When there was a lot of drive activity going on, the cursor would

jump to the left side of the screen. I was using an IDE drive.

I switched to a SCSI drive with an Adaptec 1542 controller, and

I no longer see the cursor jump. It will freeze when there is a lot

of activity, but it will go where its supposed to after things get

less hectic. Something to do with the IDE controllers/drivers ? I

don't know.
