linux slow display response

Has anyone else noticed slow display response on linux systems

Using dual processor opterons
RedHat linux
5.033 tools

Screen response is slow especially for layout. If anyone has found any
fixes I would appreciate info.

 

This is most likely a display driver problem. Display drivers often need
tweaking to get the best performance, and the drivers for some graphics cards
leave a lot to be desired.

Andrew.

 

I had also such stange effects with a Matrox Video Card.
I got better behaviour with Nvidia (FX) and best with Intel
onboard graphic card (865G).
Hope this helps.
Thanks to share your conclusions.

Hm... you aren't, perchance, using a dual-headed setup? (Just seeing
the configuration and imagining a pretty nice setup...)

I have personally seen severe issues with the IC tools and
Xinerama-enabled displays (i.e., where you have a single X desktop which
spans multiple monitors) where multiple cards were involved. There was
no easy solution here except to disable Xinerama.

 

At this time the main suspect is the video card. I will post info on what
card didn't work and what did when we get an improved setup

 

Relevant startup/debug information can usually be found in
/var/log/Xorg.0.log (or something similar: XFree86.0.log, X11.0.log,
X.0.log, X.log, etc.).

Just be sure to check the timestamp on the log file so you're not
reading an older version! (Yeah, I've been burned on this one...)

 

Which version of 5.0.33 are you using? Also, are the licenses located
locally, or served from a remote location. If remote, there is a bug
that is fixed in 5.0.55 USR3 that fixes a license access speed problem
which does show itself in startup and general slownes.

 

Switched to NVIDIA QUADRO NVX280 64MB, and problem has gone away, or atleast
been greatly reduced
