Please help me
I have an integrated intel xtreme graphics card (i810 or i845, cant tell, please tell me how to find out)
I have quake 3 installed also. When I play games, I have an extremely low framerate, and
when I check glxinfo, I see
[root@LinBox medicicle]# glxinfo
name of display: :0.0
Loading required GL library /usr/X11R6/lib/libGL.so.1.2
display: :0 screen: 0
direct rendering: No


How do i enable direct rendering,
when I load quake 3
I get this message when it crashes on loading.

Please help me enable hardware acceleration

this might not be of much help, but it's all i know to tell you:

http://dri.sourceforge.net/

Maybe see also the advice on:

http://www.xfree86.org/~dawes/845driver.html

on making sure you have the latest kernel modules.

Use "lspci -v" to find out whether you have an i810. I have i810, and I have never gotten direct rendering to work. I believe my problem is a mismatch between versions of the drm driver in the kernel and in X Windows, which mismatch has persisted though three kernels (2.5.8, 2.5.66, 2.6.1) and three versions of X (4.2.0, 4.3.0, 4.4.0 snapshot).

On my last try, a couple weeks ago, I installed an X 4.4.0 snapshot binary from Dec. 19, which came with source for a kernel drm module, presumably matching the X driver. But when I stuck it in the 2.6.1 source, it wouldn't compile. Lots of errors.

So, good luck, but I wouldn't be very hopeful of success.
