Windows are tracking mouse in a jerky motion.

[shuster]

I have a fresh install of Red Hat 8.0 on two systems. One has a Quadro4 750 and the other a GForce2MX. Based upon results from running NVChooser.sh, I installed

NVIDIA_kernel-1.0-4191.rh80up.i686.rpm
NVIDIA_GLX-1.0-4191.i386.rpm

on both systems. I made the appropriate change to XF86Config file using the nvidia driver instead of the nv driver and everything works quite well except for one annoying problem.

After I log on, when I drag a window around on the screen, it does not track the mouse movement in a smooth motion. It is real jerky on the screen. If at some point I run an application called ABAQUS (a finite element post processor) the problem goes away and everything tracks real smooth. The problem stays away until I log out and back in. It's as if the ABAQUS program initializes something.

How can I get the smooth tracking without running ABAQUS.

Thanks
Jeff

Known problem with 4191 and 2D. nVidia replaced the X Render extension with something else that seemingly doesn't work as well.

Back down to driver 3123, or maybe try adding Option "RenderAccel" "true" to your XF86Config Device section, that might help.
