I decided that I might as well upgrade the RagePro card and replaced it with a Radeon 7000. Now hardware accelleration worked but I faced nasty lockups and intermittant loss of video. The 7000 and the 7500 belong to the same family of 1st generation Radeons and I suspect that we have the same problem. In any case I have traced the problem to OpenGL and the XFree Mesa libraries. If I disable the GLX module in the XF86Config-4 file the problem goes away. But of course then hardware accelleration no longer works. Hardware accelleration works fine but slow when using the generic Mesa library and extremely fast but crashes with the XFree Mesa library. The problem is somewhere in the XFree Mesa library distributed with Mandrake. It would be interesting to compare the XFree Mesa library shipped with RedHat and the one shipped with Mandrake.
And the supermount problem? I upgraded the whole system to 9.0, but retained the 8.2 kernel. The system works fine so far, with the exception of the Radeon accelleration problem. So at this point I am waiting for XFree to be updated. I may try the current version on Cooker at some point in the near future.
Oh and the reason some responses are not showing up on Cooker is that when people do a reply, it gets addressed only to the poster, not to the list. You have to manually cc to the list.

I am the guy who has the problem with the Radeon 7500. If anyone has any suggestions, I will be happy to try them, (but note the crt_screen option suggested elsewhere did not help).
Rather confused, because there seems to have been a flurry of correspondence on this topic, but only 3 messages showed up on the Cooker list. Where can I find the rest of the correspondence?
Cheers,

I have someone at mandrakeexpeert, paid incident, that has a problem with a
Radeon 7500, the card does not work (locks up) if he uses hardware acceleration,
switching of hardware acceleration with "Option NoAccell" will make the system
work, I adviced him to get the latest packages from cooker since I saw there
have been fixes for dri applied, but his problem still persists, however RedHat
8.0 will work just fine with hardware acceleration.
Oh and if I had the money I'd buy up Mandrake as their about the best commercial linux vendor out there, unlike some m$ wannabes wearing coloured hats :-)
Maybe you can check if there are more patches available or maybe remove some
that don't work.
The incident number is : 37844
So if you need more infos just stop by and ask.
