Public bug reported:

Steps to reproduce:
1. 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.
