--- Comment #59 from Robert Wolf <wolf+freedesktop at abanet.ch> ---
One more note.

As workaround we use VESA mode (we have disabled KMS and installed VESA Xorg
driver), but the default timings are so low, so X can start only in 1024x768. I
have created /etc/X11/xorg.conf.d/monitor.conf file with content:

Section "Screen"
        Identifier "Default Screen Section"
        Monitor "default monitor"
EndSection

Section "Monitor"
        Identifier "default monitor"
        HorizSync 70000
        Option "MaxClock" "143978000"
        VertRefresh 60
EndSection

and now X can start in 1920x1080 in VESA mode.

But we cannot activate DP-1 on external monitor with xrandr in this VESA mode.
Probably with BIOS 2.10 the DP-1 was activated on boot, but with 2.18 is not.
And we can now downgrade BIOS only to 2.17, older BIOS "is denied by system
policy".

Regards,

Robert Wolf.
