Constant freezes in KDE under Mandy9
 

I'm not sure it happens to others, but for someone reason my computer freezes quite often running KDE. SOmetimes as often as 4 times especially when i'm using konqueror and i'm scrolling through /dev. Whenever this happens i have no choice to hard boot the computer which i really dislike doing. Isn't there a way to kill a task when this happens. i try Cntrl-Alt-Escape but not even that works. I think the GUI is frozen for good. WHy could this be? Are others experiencing something similar?

Thanks for your input!

I'm not really sure that ctrl+alt+esc does anything when it's not locked up


try alt+F2

or ctrl+alt+bksp

try ping or remote login from another system on the network if you have one

ctrl+alt+backspace is to kill X so yeh that should work, or try to change to another tty (not sure what it's called) by pressing ctrl+alt+f6 and see if you can get into that...if you can't then it's really frozen...

we've had similar cases like this - on machines with Intel based NICs using the buggy eepro100 module. Do you have eepro100 loaded?

just a hunch.

yeah i've tried cntrl-alt-bksp but not even that worked which i find weird. i don't know if i have the buggy eepro100 module loaded, how can i find out?

Thanks for the help! :cool:

Yea, it is hard locked then.

list modules with this

lsmod

if it only locks in X I would suspect a graphics problem, maybe check your XFree logs

thanks. i'll check my logs when i get home, but what do you mean a graphics problem--could it be a conflict perhaps with my graphics card. it works fine most of the time with the exception of those relatively few lock-ups.

there are some issues with certain cards locking up

try another window manager to see if maybe it's only kde

i ran lsmod and i didn't find eepro100 listed--so i guess i can rule that out.

but where can i find my X free logs? i looked but didn't find them

thanks!

looks like your nic is a tulip most likely linksys


ls -l /var/log/XF*
-rw-r--r-- 1 root root 48196 Nov 11 20:11 /var/log/XFree86.0.log
-rw-r--r-- 1 root root 35521 Oct 12 22:16 /var/log/XFree86.1.log
-rw-r--r-- 1 root root 35339 Oct 12 22:14 /var/log/XFree86.3.log
-rw-r--r-- 1 root root 35471 Oct 12 22:15 /var/log/XFree86.4.log
-rw-r--r-- 1 root root 34947 Oct 14 22:27 /var/log/XFree86.9.log

ok i found 2 of them, but what exactly should i be looking for. there is quite a bit of data in those files. thanks!

.....and yeah my nic is linksys...... i read those are pretty compatible with linux though, right?

Linksys is good.

look for errors in the files, but it's really hard to find a lockup problem.

If you have hardware with known issues then I would look into that.
The other thing is to try another window manager or updated version ofd Xfree.

Make sure you are not running out of memory, or disk space

maybe echo some stats like memory and system load to a file so when it locks up you can go back and look at it


And rebuilding a kernel may solve the problem if you get the kernel right.
Then again it could be that some piece of hardware is croaking.

I had a system that locked up all the time. I never found the problem, but it died one day and now it is in motherboard heaven.


This really does not seem to be your case since you say it only locks in KDE

I would think it's KDE related.

i'm not positive its kde--it was just an asumption. i haven't tried other window managers for long periods of time to confirm this, but when it freezes, i still have mouse movement but nothing else works.

none of the special button combos work to get me out so i figure its frozen for good or its just the XServer--there really isn't a way to find out, either way i have to hard boot which i really hate to do. btw what is the worst that can happen when i hard boot linux?

this is really the only error i found when scrolling down the log

(II) R128(0): [drm] drmSetBusid failed (11, PCI:1:5:0), Device or resource busy
(EE) R128(0): [dri] DRIScreenInit failed. Disabling DRI.

can't make anything out of it though.
