External display stops responding after rocket

[dr.robot]

Updated to beta 3 and now I can’t seem to get my external monitor to work. Once it gets to the “rocket” icon, the screen flickers and then quickly returns to the icons, permanently stuck with that boot screen. If I unplug the monitor from the laptop and reboot using the internal screen, everything works fine. Tried safe mode and VESA drivers, same result.

Device name: Mobile 915GM/GMS/910GML Express Graphics Controller Manufacturer: Intel Corporation

Syslog? Please.

Please upload a syslog if possible for both a working revision and a non-working revision. It might be that the driver selects another mode than before, because ProposeMode is called from SetMode (and should be called indeed), but ProposeMode should check refreshrates (which is does not yet).

Would this external monitor, if it gets out of bounds signals, stay displaying old content? So has a dynamic refreshrate control? Never seen such a situation myself yet, but who knows in these modern times ;-)

Anyway, could be something different as well I guess, but can't hurt to check if the modes set are the same or not, to rule the above problem out for you.
