Public bug reported: If I carry my suspended laptop into work and then connect it to the external Dell U2410f the monitor seems to be identified (visible in Grandr) but activating it doesn't cause any image to appear (it seems the signal is not sent).
In order to succeed at seeing anything, I have to reboot the machine entirely, with the monitor attached, at which point it not only sees the monitor, but also sends it a signal.
