Alright. I managed to fix this subject on (mostly) my own during the day that passed so I figured since so many people experienced these kind of problems, I might as well write a few lines.
Continuing from where I left off from the previous post, I first thought I should have a go at the thing many people here recommended, the XF86Config-4 -file in /etc/X11 .. I added (in the device section) :
Option "NvAGP" "1"
And when I restarted X glxinfo said I at least had DRI. glxgears still ran in about 20fps and my other gl apps ran slow, and even the demos I tested.
Btw version 61.11 of the NVIDIA driver was installed, uninstalling (NVIDIA-x.x.x..run --uninstall) and reinstalling solved this problem for a friend of mine!!!
I tried numerous things which I don't think were of any good at all, including looking around in the kernel config to see if something was missing.
A friend of mine with the same problem pointed out that a demo of ours (Outbreak, a demo group) worked perfectly although the rest of GL apps were lacking. The demo was "autumn dreams" and I knew we didn't infact use SDL there but raw x and gl calls without wrappers. So here I started to get a good feeling, perhaps it was SDL which was outdated, but I thought I had at least a reasonable good version.
It turned out I had some version from like 6 months ago, I changed the cd medias in the media manager (welcome icon on your desktop->configure tools->enter password for root->software->media manager). CD1-3 are the ones which comes with your dist, change them into:
CD1:
ftp://mirrors.secsup.org/pub/linux/m.../Mandrake/RPMS
../base/hdlist.cz
CD2:
ftp://mirrors.secsup.org/pub/linux/m...Mandrake/RPMS2
../base/hdlist2.cz
CD3:
ftp://mirrors.secsup.org/pub/linux/m...Mandrake/RPMS3
../base/hdlist3.cz
Make sure you EDIT the cd 1-3, not add new resources. These ftp directories represent the same files you have on your CD's that came with the distro, only updated.
Go back one step to the "software" category, choose install option and wait a while while it reads the packages, search for sdl and select the package which I recall was named something like "sdl-devel-x.x.x.x" .. sdl-devel is the important part. Install that package and hopefully your sdl apps will run like a charm
At least glxgear did go from 20fps to 2500fps on my system, so I know I'm on the right track now :-)
I don't know if I solved that nvidia driver causes kde to crash but if not I still think I have enough info on nvidia's developer forums to solve that one (nvidia.com -> download/drivers -> left side of the page is a forum).
Good luck with your system and please write if I helped you with anything!
Cheers
