WIth my Lenovo ThinkPad X220 I am unable to hotplug a DisplayPort-2-DVI cable,
plug the DVI end into a monitor (Samsung SyncMaster 193p+), and plug the DP end
into the ThinkPad, and it is detected within a reasonable time, with GNOME
automatically extending my desktop. If I *unplug* the DP cable, the unplug is
detected instantly.
I once waited ~5 minutes without running xrandr, and it actually detected the
monitor and reconfigured.
WORKAROUND: If I run 'xrandr' in an xterm, the monitor is detected
instantly and GNOME reconfigures the screen.
WORKAROUND: if I open System Preferences -> Display, it does an xrandr
probe and instantly detects/reconfigures the screen.
WORKAROUND: if I plug the DP cable before I open the laptop lid to wake
it up from S3 sleep, the external monitor is detected.
WORKAROUND: if I use a VGA cable instead of the DP -> DVI one, hotplug
is detected within seconds.
