I have xubuntu install on 2009 toshiba portege r600 10q
When I connect external display to the VGA port the new screen is detected, but no signal is sent to it - the screen stays blank and goes to power save mode. I have tried all options in display menu but nothing works....
....If I reboot the computer, however, the second screen starts working immediately.
So my question is the following.
Is there a background process I can restart of something else I can do to get the second screen working without a reboot?
Many thanks in advance ( and yes I have tried to look through questions and answers here and elsewhere to find solution to this problem )
Edit with output of
xrandr --query
Note that identical output is obtained after reboot (with screen working) and after connecting screen without rebook (with screen not working...)
