Thanks for your reply. By "switching to a VT", did you mean pressing CTRL-ALT-<number> to switch to a virtual terminal? That doesn't work for me, due to the grab. Pressing those keystrokes is unresponsive, thus for a standalone system in a location where there are no other computers, it still appears that the only option in the situation of hitting a breakpoint during a grab, is to force a power down and reboot. Do you know of any other options? Thanks, -- Dave _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
