Get a Lenovo ThinkPad X220 with Intel graphics (PCI ID 8086:0126, rev 09) 2. Get a DisplayPort -> DVI cable, plug the DVI end into a monitor (Samsung SyncMaster 193p+) 3. Plug the DP end into the ThinkPad What I expect: - hotplug is detected within a reasonable time, GNOME automatically extends my desktop What actually happens - nothing Things that work: - if I run 'xrandr' in an xterm, the monitor is detected instantly and GNOME reconfigures the screen. - if I open System Preferences -> Display, it does an xrandr probe behind my back and instantly detects/reconfigures the screen. - if I plug the DP cable before I open the laptop lid to wake it up from S3 sleep, the external monitor is detected. - if I use a VGA cable instead of the DP -> DVI one, hotplug is detected within seconds - 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.
