Twice Frozen Like A Block Of Ice

[notabug]

I have Saucy installed, upgraded from the 2nd beta. This install usually runs well, but the last two mornings when I get up, my computer has been frozen solid, requiring a hard reboot. I don't know what to check, i.e., log files, whatever to find out what the problem may be. I probably wouldn't understand it if I did. So where do I look for something I can show here? I don't have a problem reinstalling, been there done that plenty of times, but this one time I'd like to take a chance that I might learn from this problem.

Laptop? Desktop? What are your Power Settings? System Settings > Power Management

[notabug]

Desktop. Power settings have been disabled as much as I can so everything remains operating. I have everything unchecked. Also, my video card is an Nvidia GT430 w/1 GB RAM. The PC is of 2009 vintage.

Edit: I should mention that this didn't happen in prior Kubuntu versions and doesn't happen in Windows.

[Snowhog]

So that I'm clear; does the display show your Desktop, but *nothing* works; no mouse movement, no keys, etc., or the display is black with no mouse movement (not even the mouse cursor), and nothing you try gets the Desktop to display?

[notabug]

I'm sorry, yes, a normal desktop, the cursor is visable, but not movable. Nothing moves or is active. No keyboard or mouse.

[Snowhog]

Well, try an experiment. Tonight, before you retire, open a console and run top:

top

Go to bed. In the morning, if frozen again, what's listed under the COMMAND column in the top output?

[notabug]

Thanks Snowhog. I'll do that. Kind of like setting a trap for a "rat".

[notabug]

I apologize for taking up so much of your time today, but I just read another users reply to a thread that mentions Compositing Type: OpenGL 3.1 and I was still using 2.0. After changing to 3.1 I notice an increase in speed. If this might interfer with the experiment, I'll gladly revert to version 2.0. Thank you.

[Snowhog]

Nope. Won't interfere. Are you also using Raster for the Qt graphics system? The notes suggest to use Raster when using OpenGL. Again, these changes won't hurt the experiment.

[notabug]

I have the QT graphics set to Native, but I profess I don't know what that means. I think that was the default setting along with the OpenGL 2.0. Do you recommend a change to Raster?

[Snowhog]

Try. If it accepts, I'd stick with it (that's the combination I'm using on both of my laptops), as again, the recommendation is to use Raster with OpenGL.

[notabug]

Changed to Raster and nothing blew up. Thanks

Oh come on notabug, you're still going to run top right? The suspense is killing me! I gotta know what happens!

I'll tell ya one thing, this is making me more and more glad I am sticking with LTS releases, the forum activity spikes after each release, lol.

[notabug]

Top will be at the 'top' of my list of things to do before heading to bed.

Nice computer BTW, I'm jealous, I so want an i7.

Edit: You can keep the WinDOHS though, lol.
