Just downloaded Xfree86 4.0 and installed from source (that takes a long
time). I am trying out the glx module that it has and would like to get
SDL 1.1.1 eventually running. The only problem is all the GLX
screensavers redraw the entire screen on the visible “page”. This makes
them look really bad. Some of them flicker and the others can be seen
drawing because they are more complex (The gears demo for instance).
How can I fix this or who do I ask? I have looked at the XFree86.org
website and it explains lots of things but not this.
Any pointers?
I have to add that it is quite a bit faster than Xfree86 3.3.5 that I had
before. The integrated Hardware acceleration is a vast improvement.
Everything is great but GLX.
I have an Nvidia TNT card in case that helps.

I was looking how to do that too, but I found out its really quite pointless.
Xfree4 uses Mesa for its OpenGL support already. In your XF86config files just
put the line Load "glx"
You can upgrade the Mesa libraries Xfree uses too when new versions come out.On Sun, 12 Mar 2000, you wrote:

It’s possible that setting MESA_DOUBLE_BUFFER, MESA_BACK_BUFFER and
MESA_RGB_VISUAL might fix the problem (if X 4.0 relies on Mesa to do its
GLX drawing which seems to be the case).
Try:
export MESA_DOUBLE_BUFFER=1
export MESA_BACK_BUFFER="XImage"
export MESA_RGB_VISUAL=“TrueColor 16” # or 32 as the case may be
Then startx as normal and have a look.
I don’t know whether this will work but it might. I’m waiting for XFree
4.0 to get released as a set of RPMs and I also have much time and
effort invested in the hardware-accelerated Utah-GLX module for the TNT
and G400. It will be interesting to see whether 4.0 and XFree 4.0 play
nicely together

Actually no, X 4.0 should not use Mesa’s dummy glx implementation anymore.
As far as I know it uses the glx implementation that SGI released some time ago.--------------------------------------------------------------

Don’t use glx, use dri. And proper (full) support for the nvidia
chipsets under dri isn’t quite out yet.=====

There won’t be DRI drivers (at least not very soon). The Utah glx project is waiting for
some issues in the DRI to settle and nVidia/SGI won’t be using DRI. They will however
(or so it seems) implement a direct renderer of their own.--------------------------------------------------------------
