First is rev a1, next is rev ff.

'lshw -c display' first show 2 display (nvidia, intel), next resume and i have
only one display intel.

In xserver nvidia driver 390.25 work when reset, login, startx, but when suspen
and resume system crash, black screen.

In multiuser mode console startx work before suspend. When in multiuser mode
first suspend and resume and startx don't work "no screen found".
