Mouse/Keyboard Capture key failure

Try restarting the X server instead of powering off. I also find pressing CTRL+ALTT+DEL then clicking cancel makes mouse pointers appear. Can you give the output of:

uname -a; lsb_release -a; dpkg -l | grep -i virtual; sudo lshw -C display

Thanks

Thanks for reply.
I have no idea how to restart the X server. Sorry, however the requested output is as follows, & I hope that helps. Will try Ctrl-Alt-Del, but unless my memory fails, I don't recall anything coming up, forcing me to power down. After power request, a window does appear which offers options besides shut down. Will repeat sequence and try to finds a cancel option.

One problem solved, by one of your ingenious wizards who noted somewhere, (I cannot find it again) that if mouse config in host system, is set to have control key locate mouse pointer, the key cannot perform any other function. By deselecting that feature in Ubuntu, the right control key released the mouse pointer in guest Win7!!!!!! Bravo I wish I could find that posting again to thank the appropriate genius.
