I'm posting this to see if this has occurred for anyone else and to get any suggestions that might help. Since installing Mandrake 9.2 I have not had the Xserver run while being used for more than 5 minutes. Every desktop locks up solid. No keyboard response or anything, completely locked.
-I thought it was bad NVidia generic driver. I updated and got a whole new mess of problems on top of old ones.
-I have run XFdrake about 100 times and tried all options available, including going from XFree 3.xx to 4.xx and back.
-Thought it could be my USB mouse, swapped to PS2 mouse, no change.
-Have been unable to reinstall the NVidia drivers because the thing crashes before I can get it done, and I can't work well enough at the command line to do it.
-I have tried KDE,Gnome, IceWM, WindowMaker and whatever else came with this release of Mandrake. All lock up the same. Mozilla seems to work longer than anything, konqueror crashes as soon as it's opened.
-Command line functions all seem to work, but I don't work deep enough to really stress test things.
-I've read and reread XFree86.x.log.x and seem to have standard faults, kernel module wasn't installed at first, then failed to initialize GLX extension.
-Modified config file manually about 5 times.

I'm now wondering if there was a problem with my install, although it went easier than I had anticipated.
Are there crash logs anywhere? Aside from the XFree86.x.x.x bunch?
Is there a way to completely delete X and all things associated for a fresh reinstall? Would complete reinstall of Mandrake be better.

I will skip posting my XFree logs because my errors have been duplicated numerous times elsewhere, but their fixes don't seem to help me.
Thanks,
Dan
P.S. Not sure if this is affecting it at all but, I've never gotten sound to work yet. I always see some ALSA fault but haven't tried a fix yet.
3 hours later Instructions from another Mandrake guru--------------
The sh*t just keeps getting deeper.
I followed your instructions and this is what I got.
When running the first rpm NVIDIA_kernel-1.0-3123.mdk81up.i386.rpm I got this:
"kernel=2.4.8.26mdk is needed for installation"

And then the install dropped back to the prompt.
I'm running, kernel 2.4.22-10.
I will say that I downloaded my Mandrake 9.2 ISOs off an Asian server about two weeks ago, is there a possibility that I have been doing all this with an outdated kernel or something? Or is Mandrake not identifying my kernel right?
Anyway, I'm out of ideas for now. I was going to go out and look for other NVIDIA rpms but thought better of it. I was running the "nv" driver with the original problem. However I did try the XFree86 4.x.x GeForce3 (generic) driver at one point and got the same results so I switched back to the "nv"

P.S. The NVIDIA rpms require that the basic driver and the GLX be installed seperately. However this was not the case with the tars I loaded the other night, or I did it wrong from the beginning.
Remember though that I originally started trying to update to cure the same problem I have now (lockups).
