[Gentoo] DisplayManager userland crashing, no displays

[maggu2810]

I rebooted my machine to find the simple steps:

• loading evdi kernel module before X has been started
• start X server (GNOME session at my current setup)
• start "DisplayLinkManager" (currently using root privileges)

Now xrandr shows the provider (listproviders).

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel
Provider 1: id: 0x11c cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

After that is used

xrandr --setprovideroutputsource 1 0

and activated the output "DVI-1-0" after all (in the run before it has been named "DVI-1-1").

All fine.
