X11 crashes on boot or when a USB video device is plugged in.

I have a new MIMO UM-760CF.  I have tried three different 42.1 computers.  X11 crashes on each one if the MIMO monitor is plugged in.  X11 dose not crash on 13.2, still working on getting the driver installed and working on 13.2

Comment 1 Egbert Eich 2016-08-01 13:53:08 UTC
Your combination is invalid: you cannot combine NVIDIA's proprietary libGL with glamor.
Glamor is used by the modesetting driver which is loaded for you extra device.
The only this *might* work is by disabling glamor for 'modesetting'.
Comment 2 Forgotten User PzXOktpH6D 2016-08-01 17:49:16 UTC
Had to create a static xorg.conf. I created 20-modesetting.conf but then I got no devices found.

Section "Device"
    Identifier  "MIMO UM-760CF"
    Driver      "modesetting"
    Option      "AccelMethod"    "none"
EndSection

Xorg.0.log shows that it see the USB monitor but I am not getting anything displayed.  I posted to a thread in the forum.

Thank you for pointing in the right direction.
