I've had similar things happen to me. 1. When the screen is black, can you still see the mouse arrow? 2. Can you switch to the console? To see if you can, use Ctl-Alt-F3 to bring up tty3. 3. If you can get to a console, log in and issue the shutdown command, like this:
ubuntu login: yourusername Password: yourpassword <-- Nothing will show here when you are typing yourpassword. Just trust your typing and then hit enter. <the boilerplate yada-yada-yada> [EMAIL PROTECTED] sudo shutdown -hP now Password: yourpassword 4. If you cannot get to a console, does the machine respond to a Ctl- Alt-Del reboot (The infamous "Three Finger Salute")? 5. If the machine does not reboot after Ctl-Alt-Del, does your keyboard NumLock LED light respond when you hit the NumLock key? 6. Post as an attachment /var/log/Xorg.0.log. 7. Post the RELEVANT portions of /var/log/syslog. The relevant portions are those lines with the timestamp of around the time you tried to shutdown. DON'T post the entire syslog, which would probably be an enormous amount of irrelevant information. (Unless your system just reloaded the logs.) 8. Is this a Dell computer? I have several Dells, and they all have weird hardware issues. I've figured out solutions for all of them, but they are strange until you get them figured out. Post back with the answers. It will help troubleshoot where the problem is.
