Please help me find the cause of freeze ups

Post by Daan » Fri Nov 22, 2013 9:16 am

Hi,

My HP desktop at work freezes regularly, and I don't know how to find out what is causing it.

The freezes occur when I've been away over night, either after I suspended the system to RAM or when I've left it running, and no CTRL+ALT or SysRq key combination does anything. After suspending, normally touching the mouse is enough to get back to my work, but not when it is frozen. All I get then is a black screen. Yesterday I left it running, and this morning I found it frozen, with the screen saver displaying the time as 00:14. I pushed the power button for a couple of seconds to reboot the system.

Where can I look to see what causes the freeze ups?

Thanks,

Daan

Daan,

Try going into power management and turning off suspend / Hibernating settings. Let it run over nite and see if you still are having this problem. You can look in /var/log/kern.log and see if something points it out but the freeze up might prevent logging anything to kern.log.

Should the freeze up stop after power management is turned off then its a problem with suspend / hibernate. If it doesnt and still freezes up, I would start looking at the screensaver. perhaps change it to just a blank screen.

Hope this helps...

You can try getting kernel 3.11 from Testing and see if the problem goes away.

Hi coffee,

Thanks for your suggestions.

Under gnome-control-center -> Power, "Never suspend" was already set. Under Brightness and Lock, lock was switched off and turn off screen was set to 30 minutes. I would set it to never, but there is no such option.

Under cinnamon-settings, there is Screensaver & Lock settings, but it only has an option for an away message.

(So confusing, these settings in different places.)

I have now uninstalled (purged) cinnamon-screensaver, I hope that helps. (I will switch off the monitor manually when I leave.)

/var/log/kern.log's oldest entry is from this morning, when I booted the system.

Monsta, thanks for the suggestion. I'll try if other measures do not succeed.

So,...

My system has been running uninterrupted and without freeze-ups since I've uninstalled cinnamon-screensaver. I haven't tried suspending it. The screen switches off automatically if I have been away for a while.

So cinnamon-screensaver has found it's way back onto my system, probably during a large software upgrade, and the freeze-ups are reoccurring. I would uninstall the screensaver, but aptitude then wants to remove mint-meta-debian-cinnamon, and I do not know whether is is save to proceed.

Can I do without mint-meta-debian-cinnamon?

Code: Select all

$ sudo aptitude remove cinnamon-screensaver

Metapackage can be safely removed (it's there for convenience), but I heard that cinnamon-screensaver is an essential part of Cinnamon 2.0, and the latter may cease to function without it. Be careful.

Then why doesn't cinnamon depend on cinnamon-screensaver?

Is there a way switch off the Cinnamon screensaver? I don't see such option in Cinnamon Settings.

Thanks!

As Monsta suggested earlier, a newer kernel could fix the problem - it did for me.
You can try getting kernel 3.11 from Testing and see if the problem goes away.
These suggestions may help, if that doesn't work.

Thanks for your suggestions.

I think I already have kernel 3.11:

I just found out that I can login on my frozen computer through ssh. I thought I checked before, but I only succeeded just now. Apparently it's not as frozen as I thought. Still, the computer does not respond to mouse or keyboard input (including sys rescue key combinations). And the screen is frozen. This happens once in while, either when I am working on it or when the screen saver is on.

Now I tried killing several of the Cinnamon processes that showed up with ps aux|grep cinnamon. A few seconds after the last one I tried,

Code: Select all

daan@lophelia:~$ killall cinnamon-session
the screen went black and then the graphical login screen appeared. :)

How can I now find out the cause of the freeze-ups and a way to prevent them?

Here's kern.log in case that helps.
