Hi, I'm using Ubuntu 10.10. I'm experiencing frequent crashes to my distro for a while now.A black screen shows up out of nowhere and i have to press the power button to restart my system.
I can't even open up the virtual terminal when it is hung.That Ctrl+Alt+F1 to F7 combinations does not work.Nor does the Ctrl+Alt+Del.
Here is a few line from my /var/log/messages file after the reboot
Code:
