Re: gpm and X mice jitter
In my experience, it depends on the video card. I had problems with
the mouse in X with a Nvidit TNT Riva card until I used gpmdata. With
gpmdata, I found that often after using X and switching back to a text
console that gpm would not paste correctly.
When I switched to a new motherboard with onboard video (SiS 630ET) the
mouse acted strangely in X with gpmdata used, so I tried using
/dev/psaux. Now the mouse works fine and I no longer have any problems
with gpm either. I needed to revert to xserver-svga (3.3.6) with this
chip (the 4.1 driver has problems) which may (or may not) be a factor.
