The title about sums it up.... I'm running Redhat 8
with the 2.4.14-18 kernel, on an AMD K6-2 450 with 256Mb of RAM.
Any time I try to log into KDE/Gnome/Windowmaker, It comes up and
will return a segmentation fault, and will then spit me back out
into the login (Except windowmaker, which asks me if I want to load
it again, which results in an endless loop of segmentation faults)
I tried deleting all the users, and creating new ones -- with no
luck. I don't *mind* running as root for daily stuff, but I do spend
some time online, and I don't want to expose myself to any programs
that might take control of my processes. I'm loathe to reinstall,
and am wondering what, if any, options I have, or if any of y'all can
tell me how to go about fixing this?

How are you creating your users?

This is definetaly odd.

**also** , a segmentation fault is often caused by not a corrupt program, but a program that isnt compiled properly, or memory related.

But doubting that you compiled any gnome or other things you are using, (I dont know, did you compile the program that is giving you a segfault?) +TRY+
to run 'setup' from the command line. or redhat-config-services as root.

Turn off a lot of services that you don't need.
I know right about now you are thinking, WTF, are you some kinda Microsoft representative?
But, no I am not, just thinking that maybe you have no swap space, very low memory, may even be causing the error.

So how are you creating your users?

I've tried using KDE/Gnome's User creation tool, as well as doing it from the console...

And... I'll give that other stuff a shot. I'll try to post back later, but I'm dead tired...

Sounds like a permission problem. Did you compile from source the window managers?
