Hi, Currently mousedev combines all hardware motion data that arrivers since last time userspace read data into one cooked PS/2 packet. The problem is that under heavy or even moderate load, when userspace can't read data quickly enough, we start loosing valuable data which manifests in: - ignoring buton presses as by the time userspace gets to read the data button has already been released; - click starts in wrong place - by the time userspace got aroungd and read the packet mouse moved half way across the screen. I am seeing the second simptom on Fedora Core 2 in X. ( I click on a windows title, move the mouse and what happens is than a selection rectangle is drawn on the desktop, starting a few inches away from the real click position ) Is this the cause ? Regards, David P.S.: Is there a bug about this in bugzilla.redhat.com ? ( or elsewhere ? ) ---------------------------------------------------------------------------- ----------- http://noepatents.org/ Innovation, not litigation ! --- David Balazic mailto:david.balazic@xxxxxxxxx HERMES Softlab http://www.hermes-softlab.com Zagrebska cesta 104 Phone: +386 2 450 8851 SI-2000 Maribor Slovenija ---------------------------------------------------------------------------- ----------- "Be excellent to each other." - Bill S.
