Hi all, I have a Thinkpad X200 (Librebooted) that I'm faffing about with. Everything works as it ought, except I get some odd behaviour when I plug in a VGA connector. A moment after it is plugged in, the screen on the laptop goes black, except I can still see (and move) the cursor within the bounds of the laptop screen. The external monitor is also completely black. The cursor flickers a little bit. After I unplug the VGA connector, everything goes back to normal. This only happens when there is an actual monitor on the other end of the cable. Plugging in a loose cable does nothing. I haven't yet tried to connect to a different monitor. I have the output of `journalctl` during the behaviour here: http://susepaste.org/39924818 Particularly, this line sticks out to me: Sep 23 21:31:02 carmen-thinkpad kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun But it's not something I know how to interpret. I have tried: - Using IceWM instead of Gnome. - Using LightDM instead of GDM. - Using the VGA port on the dock instead of on the laptop. None of the above yielded positive results. Maybe someone can help me? Yours with gratitude, -- Carmen Bianca Bakker en eo fy nl
