I've just installed Ubuntu 10.04 LTS 64bit on my i5-2400 system, and I'm experiencing very laggy keyboard and mouse input.
I have to type really slowly or I some keys will not get registered. Also, the mouse cursor moves around very slowly at a very low frame rate.
I've checked my keyboard and mouse settings and they seem to be fine. System monitor doesn't show any processes taking up significant CPU utilization. What else could be wrong?
Anyway, I'm using 10.04 LTS since I'm building the Android source code and that's the official supported version. I tried using 12.04LTS but it didn't work.
And my keyboard/mouse are both USB, not PS/2.
I suspect it's a driver issue, probably something to do with my USB drivers, but not sure where to get updated drivers backported for 10.04?
