2.5.44: Still has KVM + Mouse issues
Quoted 8 lines · Jon Grimm
If a fix is available I'd love to test it out as I still see strange
behavior
with an Intellimouse and my MasterView CS-104 KVM switch (yep its old).With a few trusty printks, it looks like after I switch away & back
into 2.5.44, the mouse is now sending 3 byte packets instead of the 4 it previously was.
I had the same problem also with an MasterView KVM and intellimouse. They seem to have some problems in the mouse protocol implementation in the switch.
The mouse can be identified through the KVM as a Intellimouse, but when actually talking later some bytes get dropped. It actually said on the wrapping that it should work with Intellimouse, but I think they lied (or Windows uses some different way to initialise the mouse that works)
Boot with psmouse_noext, that should fix it. It runs the intellimouse as a plain PS/2 mouse. You lose the additional mouse buttons and the scroll wheel, but they never worked through that KVM anyways.

Thanks Andi,
The workaround sounds reasonable.
