Laptop 3D PerformanceI have been playing around with a bunch of different things trying to improve the 3D performance of the Radeon 7500 mobile in this laptop. I've seen glxgears scores up in the 1000 range, and even saw one guy scoring 1400+... I am getting a mere 220fps right now so I figured I'd document my journey to better fps. In the past I have seen big gains by enabling SBA and FastWrites, but this was on desktop Nvidia cards (a 6600gt and 6800)... This mobile 7500 probably won'ttake to overclocking very well (and I'm not going to overclock it to wring another 30fps out) so I'll have to focus on driver compatibility and tweaking. BTW, my A643200+@2.5ghz/1gb pc4000/gf6800@450/850 yields about 12000fps, and my Semp2800@2.0ghz/1gb pb4000/gf6600gt@536/974 averages around 7000fps. When I started they were 8000fps and 5000fps respectively. UPDATE: I've just gotten the DRI on my laptop working properly. I am now getting 1800+fps running glxgears (up from 220 a half hour ago). I simply went to http://dri.freedesktop.org/snapshots/ and downloaded the most recent radeon package (it was built this morning). I untar'ed it, ran the install script, killed gdm, unloaded the radeon driver, and restarted gdm... Problem solved! A little tuning with driconf (enable HyperZ and change TCL to software) is giving me a solid 2045fps.. wow, that is almost a 1000% improvement! The preceding has been an excerpt from 8cylinder.org

AWESOME - I would like to do
AWESOME - I would like to do this with my 3ghz celeron and 9800 Pro. Now, I just installed Ubuntu a little bit ago, and I am a complete noobie. How do I: "I untar'ed it, ran the install script, killed gdm, unloaded the radeon driver, and restarted gdm..." ?
Would appreciate a step-by-step. Thanks!!!!
evil: I believe a 9800 pro
evil: I believe a 9800 pro would use the radeon driver, available at http://dri.freedesktop.org/snapshots it might use the r300 driver.. in which case you would download the newest r300-xxxyyy-xxxxxxx snapshot.
These files are stored in a bzip2 tarball which can be extracted with the following command:
tar jxvf radeon-xxxyyy-xxxxxxx.i386.tar.bz2
then cd radeon-xxxyyy-xxxxxxx
sudo ./install.sh
sudo modprobe -r radeon
sudo /etc/init.d/gdm restart
r300-xxxyyy-xxxxxxx is obviously supposed to be replaced with the actual filename and directory name
voila
kernel modules error
thanks bob, I believe the right drivers are the r300's...
after following ur instructions i get:
Compiling...
ERROR: Kernel Modules did not compile
The DRI drivers can not be installed without the latest kernel modules. Installation will be aborted. See the dri.log file for information on what went wrong.
And so the dri.log says
./install.sh: line 678: make: command not found
and so i'm like... wtf
I tried some input from these forums: http://www.ubuntuforums.org/showthread.php?t=7200&page=2
and went ahead and tried what post 19 read. I also tried it with 386 instead of 686.
NOW not only does the ./install.sh give the same error, but i have 3 different versions of ubuntu listed on grub... a;lsdfkya-0357235
any help would be appreciated!

wow, sorry for the delay in
wow, sorry for the delay in response, but on ubuntu you must install the build-essentials package to get gcc/make/autoconf etc. good luck!
