Frederic,

Have moved the old/ modules into drivers/ (and commented out Option
"NoAccel"). When I first went to restart the X-server, the whole
computer rebooted. But now the reboot has finished, X seems to be
working OK. I don't get the KVM freeze like before.

I'm not sure how I test whether hardware acceleration is working, but I
tried running ArmageTron and TuxRacer. ArmageTron was running at 1fps,
which is unbelievably poor (I think I get around 150fps on my laptop).
TuxRacer also appeared to be running at only 1 or 2 fps. Would I be
right in guessing either that hardware acceleration is still not
functioning, or that the hardware acceleration is broken and actually
making things slower? I'm almost inclined to the latter, as this is the
worst graphics performance I have ever seen on a linux computer - far
worse than you would expect from just missing hardware acceleration.

Have you seen the message on Cooker suggesting the problem is in
OpenGL/Mesa libs? Could this be connected to this FAQ issue I have just
found at the DRI website:
http://dri.sourceforge.net/faq/faq_display.phtml?id=42
I appreciate that this is for PCI, whereas my card is AGP, but could
they be related, and could this be a clue to why Mandrake's default
Radeon drivers sometimes don't work with the Radeon 7000/7500?

I've tried to find where I can get info about the X-server process. The
best I can find is under Information in the KDE Control Center.
Unfortunately, this doesn't seem to give me any cut-and-paste option.
I've typed out as best I can whatever looks like it might be significant
information, and attach it below.

Cheers,

Bruno Prior

When Mandrake 9.0 initially came out, I gave it a test drive on my hardware before upgrading. In the process I encountered two showstoppers. The first was the famous supermount fiasco redux. The second was the fact that hardware acceleration no longer worked on my ATI RagePro card.

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.
