View Full Version : [ubuntu] Occasional Complete Lock Up / Freeze

September 23rd, 2008, 12:28 PM
Hi Guys,

I have been using Ubuntu now for a little over a month and I have to say it is quite an impressive OS. However, occasionally (maybe once a week) my laptop randomly freezes and there is no way out of it apart from doing a hardware restart.

I have a Dell XPS M1530 and I notice that when the computer freezes both the CAPS LOCK and NUM LOCK LEDs are flashing, now I'm not sure what significance this has in working out what is going on, but I'm hoping someone out there knows.

Apart from that, I can't think of anything that would be causing this (this is my second installation of Ubuntu, and it happened in my original installation of ubuntu also)

Any Knowledge on the situation would be rather helpful

it depends a bit, is there anything in specific you remember doing when your computer crashed?

there are a lot of possibilities here, for one it could be a hardware related problem.

there are number of things you could do, these are pretty much summarized in this post: http://ubuntuforums.org/showpost.php?p=5839686&postcount=2

generally the usual suspect here is compiz/graphics card drivers, if you re up to it, perhaps disable compiz for a bit and see if the freezes return.

also some laptops have troube with sleep/suspend...

there was a thread related to your laptop, from experience it is handy to find people with the same computer as you.

I googled around and I found this thread:http://ubuntuforums.org/showthread.php?t=652364


I also found this manual of ubuntu specific for your laptop.


good luck

I don't know if this can help (probably not...) but I had the exact same crash last week (with the LEDs blinking). I was using amsn with webcam (with the video settings window open) and was typing like a madman, I put it down to some buffer overflow of sorts as it never happened again...

Bottom line, do you have any devices that eat a lot of system resources? If they are external, you could unplug them and see if it gets better, if they are internal, maybe you can turn them off by a switch or in the BIOS?

Best wishes,

I also experienced system freezes on my Packard Bel bg46 notebook about twice a day or so. After I turned off wifi in the system settings, I've had no freezes anymore....
