System frozen randomly

[Walkinraven]

Ubuntu frozen randomly, when it happening, all hot key is not work, I have to forcing power off.

This happened even with a fresh installed system, so I prefer to thought it may be caused by some hardware driver.

I install Ubuntu 11.04 64 desktop on Dell Latitude e6520 laptop.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please run the command 'apport-collect 839774' which will attach necessary information for debugging this as an Xorg problem.

If you could add more information about the freeze that would be great, like if you can move your mouse, switch to a VT (Ctrl+Alt+F1) or even if you can ssh into the machine.

Thanks in advance.

Sorry, I'm afraid I can't give any more info. for I've reinstall with a 32-bit system, hoping this is a 64-bit only problem.

And, If you mean when it happen, I may:

Run 'apport-collect 839774' to provide more info.

I think it impossible, for I can't move my mouse, my keyboard is inactive, Ctrl+Alt+F1/T ... no even Caps Lock is unavailable.

And it may take many hours to happen the accident.

I guess it may be caused by Adobe Flash plug-in, for right now it happened again on 32-bit system. It seems each time, there is a firefox with flash page opened.

[Walkinraven (walkinraven)]

No relationship with flash, 32/64 system ... no particular high-level application, for it happened several times with no particular application.

After several system updates, (automatic update, with LTS-only setting), when it happening the mouse could move, but others keep the same.

After updating to 11.10, the problem disappeared.
