XGL notes from Dr. Red (Latitude D600)


Dr. Red installed XGL on a Dell Latitude D600 running SUSE Linux 10.0 and shared his experiance with the Moose.
Thanks for this post, Dr. Red

His advice: Forget it...... 2 slow.....get a new machine
But wait...read the comment on this post...

Notes:

Dell Latitude D600
32 MB DDR video and ATI Mobility Radeon 9000 E
Suse Linux 10.0
KDE

First of all I installed the rpm's found on en.opensuse.org/Using_Xgl_on_SUSE_Linux, also needed to install the compatibility packages because i'm running v10.0. No problem so far...

I added the Load "glx" option to my /etc/X11/xorg.conf, (Module secion).

After this, trying to run "compiz" gave me the message that double buffering was not supported. Tried to tweak my /etc/X11/xorg.conf, but that made no difference. After getting the latest linux ati driver from their homepage,

The second message I got was an composite message. I added the Option "Composite" "true" to my xorg.conf section "Extensions" so i looked like:

Section "Extensions"
Option "Composite" "true"
EndSection

(the website is stating that this option is not needed, but i could not get it to run without).. I got rid of this message when added this option, and restarted kde.


The third message I got, was: (When running from my kde desktop)..

GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No managable screens found on display :0.0


I logged out of Kde, and logged into a console session.

I ran the command: Xgl :1 -fullscreen -ac -accel xv -accel glx:pbuffer & DISPLAY=:1 xterm

This gave me a graphic shell, with a single xterm..

From this xterm i ran: startkde..

Kde started and the response was very very very very very... I meen, very slow....

After this I decided not to go further because the lack of graphic capabilities of this laptop. One positive thing, the windows where wobbly, due to the response of my system... ;)

sync
reboot

Thanks Dr. Red for this post

The redrawing in XGL is a lot slower than in the regular X server, for some reason. So it seems very very slow.

However, once you start Compiz, the redraw problem goes away completely, and everything's very smooth.

My laptop is (I believe) slower than yours - P4M 2.0 GHz, with a 32MB GeForce MX440. And Compiz runs well on it while using nvidia's binary drivers..

In this stage of XGL development, GEFORCE chips do work a lot better.

If you're thinking about installing XGL, I would go for a GeForce 6600 or 6800 with NVidia prop. drivers. These are quite affordable aswell.

Do these cards fit into my laptop?

Starting compiz did not make it go any faster.. After this I tried to tweak the setup, and wrecked my configuration..(Again) (and why make a backup?).

I got Xgl and compiz running, but still huge performace problems. I'm currently reinstalling my system and give it another try,. I was using the driver downloaded from Ati, I think that was/is the problem....
