I have two different QNX-6.1 boxes here that are connected to
Aten MasterView Plus 8-port KVM switch. When I bring up Photon
on either of these boxes, I can see that any movement of the
mouse puts a huge load on the CPU. System monitor shows that
CPU is busy for few second after I move mouse by few inches.
Both systems become essentially unusable after I start Photon.
One box has got P2-400MHz CPU, 512 MB of RAM, “rage” video
driver and 1280x1024x16 display configuration.
The other box is P2-333MHz, 128MB of RAM, and “rage” driver
as well, in the same configuration.
The mouse is the simple PS/2 Microsoft mouse.
Here is output of ‘uname -a’:
QNX unix-1 6.1.0 2001/08/10-15:17:25edt x86pc x86
All the other [non-qnx-6.1] boxes connected to that KVM
switch work just fine. There is system monitor in QNX-4.25,
but my feeling is that this problem doesn’t happen when I
boot either of these boxes with QNX-4.25.
Could anybody please provide me with any idea of what
could possibly cause this problem.
