radeon 7500 works bad with Mandrake 9

[Louis Coilliot]

I got a problem with an ATI Radeon on a notebook Compaq Presario 2822ea.

X starts, but the display is ugly.
(it's the same with RedHat...)

Could somebody tel me good modelines/horiz-Vert frequencies for this notebook under linux ?

What are the resolution specs of this screen ?

Thanks
Louis

Radeons can be a pain to configure, especially on a notebook. As long as you are running XFree86 4.0 or greater (hopefully 4.2.x), you shouldn't need to use modelines. In fact putting in the wrong ones just makes things worse. You should be able to just use 'Generic Laptop Display Panel' for your monitor and specify radeon as your driver. In fact you can see the /etc/X11/XF86Config file I use at

You will probably be able to enable hardware acceleration with your hardware. In any event, the XF86Config file I use should at least get you started. If you continue to have problems, post the lspci output for your hardware and maybe a copy of your /var/log/XFree86.0.log.

Hi Louis,

I had a similar experience, but with an nVidia GeForce2 card on SUSE 8.1

I had to go to nVidia's web-site and install it's specialty linux driver.

Might be something to check.

HTH,

Than you but it's specific to Radeon.
I know how to do it with nvidia cards: ither nv or vesa, or much better, the nvidia proprietary driver.

I'd like to have an nvidia card !

Now I know it's better to avoid radeon 7xxx on compaq linux notebooks.

I managed to to it with:
http://dri.freedesktop.org/wiki/

and Xfree 4.3, with linux kernel 2.4.26

OpenGL works well now:

glxinfo says:
OpenGL renderer string: Mesa DRI Radeon 20040929 AGP 1x x86/MMX/SSE2 TCL

and glxgears says:
5617 frames in 5.0 seconds = 1123.400 FPS
