Linux "crashes"


Hi all,
I installed Linux quite happily a few months ago and I've had no problems with it, until last night. After leaving the PC unattended for a few hours, Linux crashes. It has done this twice now.
For instance, I click on "kppp" on my toolbar.
The toolbar the vanishes;
I can't right click on the screen - nothing comes up;
the mouse cursor becomes very sluggish and sometimes remains stuck;
then the screen icons (Netscape, Star Office etc.) vanish.

The only way to restore the situation is to switch off the PC and back on again.

Has anyone else had this problem: as I say it has only just started to happen but is very annoying.

Thanks for your help

Paul

I'd guess it's just X that is having a problem, not linux as a whole. You should restart teh X server, and NEVER turn it off at the wall...
Ctrl+Alt+Backspace should kill the X server, or Ctrl+Alt+{F1-F6} should take you to a shell, where you can do whatever you want.

You've not given enough details about what manager you're using when this happens. gnome? kde? windowmaker?

Whoops, sorry I forgot to include my windowmanager: its KDE.

What mystifies me is why this has only just started to happen;
it makes Linux inconvient to use (almost as bad as Windows ME which crashes every other day)!

Should I juist restart the Xserver with "startx"?

It has now "crashed" for the third time, requiring
me to shut the PC down completely and start up again.

I tried "ctrl + alt + <-", but all the icons disappeared, and the screen went a mottled green colour. Imagine what happens when you log out, and the screen loses its icons and the colour screen goes muted: thats what it looked like.

Using ctrl + alt + anything else resulted in nothing happening.

Help!

Sounds to me like you have an X problem not a linux problem. What video card and mouse do you have? Also, have a look at /var/log/XFree86.log for any errors and post them here.

Even more serious!

I've had a look in the XFree86.0.log file, and also /var/log/messages. Theres nothing in
there that suggests a problem.

A more serious crash happened just now. The system
locked up in the middle of a kppp session. Killing the X server, and switching to a shell didn't work (the screen had locked up completely). I HAD to
switch the PC off, after waiting a while.
When I rebooted, the PC just hung after the
memory check.
Using the SuSE bootdisk, I managed to log in,
and for one heartstopping moment, it looked like
my lilo.conf file had been gobbled up! I then used my own boot disk, and after the 10th attempt, managed to get linux nearly up and running. The
bootup sequence reported many many fsck problems, so I had to log in and hit yes when prompted to
fix/ignore etc. inodes etc. Its now up and running
and I suppose the inode problem is due to the forced shutdown, but just what the hell is going on here?

Cheers

Paul

You could have a hardware problem, is there any one thing that causes the lockup and can you make it happen with this action or is it a random thing?

Hi,
Well, I've been using SuSE since July, but have only had internet access for the last three weeks
when I bought an external modem. This is the only new piece of hardware added.
The problems only started 2 days ago, and if theres one common factor, its when I am launching kppp, or, in the last case, in the middle of an internet connection.

I am confused - and increasingly annoyed! Its tedious performing fsck.ext2 every few hours due to the crash.

Cheers

Paul

The first thing would be to test the modem on another computer and/or OS, it seems to be the first line of enquiry. If it checks out ok then I'd be looking at your video card for possible problems/conflicts.

I'm sure that the modem is OK because I got it from a friend who'd used it with his Linux setup.
He didn't need it anymore because he's switched to
ADSL.

By the way, my mouse is just a "standard" one, and
my video card is a NVIDIA TNT2 make if this helps.

And yes, Linux has crashed again- I'd left the machine for a full day and when I went back to it,
the desktop + icons appeared very sluggishly, mouse movement was slow and attempting to kill X or switch shells resulted in nothing happening.
So, I switched off and got the familiar {DriveReady SeekCompleteError} and {UncorrectableErrors} during fsck.

Bah!

By the way, almost forgot, the modem works fine with Windows ME.

Are you using the NVIDIA drivers or the nv driver that comes with XFree86? and what version of XFree86 are you using?

I'm using the NVIDIA driver that came "as is" with XFree. The version of XFree86 is the same that comes as default with SuSE 7.2; 4.0.3

Ok, this is a long shot but worth a try, if it dosn't fix the lockups you'll at least have hardware 3d. Go to http://www.nvidia.com/view.asp?PAGE=linux and download the official drivers in tar.gz format, _follow_ the install instructions to the letter and see if it helps. Make sure you read the TNT notes in the README file. I've also got a copy of a script that checks the install of the nvidia drivers, its too big to post here but if you send me an email I'll sent it to you.

it sound's pretty unlikely to me that the video drivers would really have anything to do with a lockup during a kppp session. although, i wouldn't rule it out completely.

have you tried using wvdial to connent? it's a command-line program, but it works as well as kppp - and if it works without crashing the system, then you can pretty much narrow the problem down to kppp. that would be my best guess.
