Description of problem: I've got a Thinkpad T410, docking station, external monitor connected to HDMI3. F14 with all updates applied. When X starts it extends the desktop across both monitors just fine, but when I run: xrandr --output LVDS1 --off --output HDMI3 --auto --primary the laptop monitor switches off as expected, the external monitor continues running but only displays black and the mouse cursor. Otherwise the machine acts normally and the mouse cursor moves if I move the mouse, and I can change VT to and from X. When I issue CTRL+ALT+BACKSPACE, the expected X display flashes up very briefly before the X server dies and re-inits. Version-Release number of selected component (if applicable): kernel-2.6.35.10-74.fc14.x86_64 xorg-x11-drv-intel-2.12.0-6.fc14.1.x86_64 How reproducible: Always. Steps to Reproduce: 1. Log in 2. Open terminal, type xrandr --output LVDS1 --off --output HDMI3 --auto --primary Actual results: Blank screen on external monitor, but with mouse cursor. No obvious errors in dmesg or /var/log/Xorg.0.log. Expected results: Normal desktop on external monitor Additional info: Please let me know what steps I can take to submit extra debugging info and I will do so.

I'm not seeing this with F16 or F17 - closing bug.
