Problem with ATI X300

KarlHungus · 11-23-2006, 04:49 PM

Hey,

I am running FC5 on a inspiron 9300 with 1.7GHz Centrino and X300 64MB graphics card. I have installed the fglrx driver from livna using: yum install kmod-fglrx.

'rpm -qa | grep fglrx*' gives me the following output:
kmod-fglrx-8.29.6-1.2.6.18_1.2239.fc5
xorg-x11-drv-fglrx-8.29.6-1.lvn5

My xorg.conf file looks like this (I haven't shown the stuff I thought was irrelevant such as Input Devices):

Section "ServerLayout"

It seems to be set up but when I run glxgears maximized to full screen I get about 180FPS! This seems very slow in comparison to what other people are getting from similar systems. Could someone please help me out to find where my problem is since I'm very new to linux and totally new to FC.

Any help would be appreciated

To find-out if direct Opengl rendering is enabled:

Code:

glxinfo | grep direct

Try running:

Code:

fgl_glxgears

[brendanm@localhost ~]$ glxinfo | grep direct
direct rendering: Yes

fgl_glxgears is giving me about 150FPS when maximized. It used to be 180FPS so I'm not sure why its gone down even lower.

You are not suppose to maximize-it, what does it give you when run at it's default resolution?

It gives me about 280FPS. Thanks for the help.

That score is about right for an x300 card. It should be good enough for ut2003 in 1024 and ut2004 in 800x600.

KarlHungus · 11-24-2006, 03:06 AM

Ok, I thought it should have got a higher score than this. Thanks for the help.

Just a comment about glxgears, the scores from that test programs have dramatically gone down since the 8.25 drivers. For example an x600 which used to do between 2400 and 2700 with the 8.25 drivers do now between 250 and 500 on glxgears with the 8.31 drivers. But, the actual performance is everybit as fast as it was in the past, even if the new glxgears results took a huge drop.
