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".
