Hi there. It's been about 8 months now since I had installed linux for the first time. And generally i'm happy with the OS. But there is one thing that consistently gave me problems and that is shutting down X. Sometimes, when I shutdown my computer, my screen goes bad (it's hard to explain what exactly happens) and my computer locks up. It's not a kernel panic, but no key combination works any more.
I have searched the form and it turns out other people have the same problem. See this thread.
This happens once in about 20 shutdowns so it's not a big deal. But this should not happen to an OS that is (supposed to be) legendary stable.
I heard his could be a hardware problem. Here are my system specs :

OS1 : windows XP prof. edition
OS2 : Linux kernel 2.4.10-4GB
HD : seagate 60 GB 5200 rpm
CPU : 900 MHz AMD atlon
mobo : asus (don't know exact specs)
graphics card : nVidia gforce 4 mx, 64 mb( )
soundcard : als4000
modem : don't know, it's a internal, non-winmodem.

I have recently re-installed my system and the problem is still there.
Does any one what could be wrong ?

By goes bad, do you mean you get all sorts of funky colors and such? If
so, I would guess that you don't have the correct video module installed.
Maybe check out nVidia's website, they apparently have linux drivers for
their newer cards. Also take a look at the XFree86 website
http://www.xfree86.org

You could also be having memory problems. If the above doesn't work,
go to http://www.memtest.com and read about their memory test kernel.

O, I forgot to post my XFree86 version. It 's XFree86-4.1

Yes, by going bad mean I see all kinds of strange colors.
I don't think the videocard is causing the problem. The reason I think this is because i have just recently installed it. (About a month ago). Before I had a savage 4 card and it gave me the exact same problem. But I it's generaly a good idea to install the latest drivers so i'l install them any way.
O, and I have 160 MB's of ram installed which should be good

I'l checkout the sites and report back

Yeah, I was having a similar problem with an ATI card. It was being caused by the wrong module, and incorrect options in my etc/X11/XF86Config file.

The amount of RAM wasn't what I was questioning, it was whether it was
all good. Since you had a problem with a different card, I think you may
really want to check your RAM to see if it's bad. However, I don't think I've
ever seen bad RAM cause video problems like this, it usually causes a
segfault and a core dump (or a complete system lockup). . .

He, I think you are right. Come to think of it, I don't think I had the problem when I installed the nvidia drivers. I't hard to tell since the prob. didn't happen that often.
You see, I had to re-install my system a few days ago and I have yet to install my nvidia drivers again. Maby my old card was also installed wrongly.
Thx for the reply.

Well, if you get it working, let us know. . .
