the same issue with Intel Atom x5-Z8330 and

For N5105 it helped to set i915.modeset=1 as it -1 by default, which means "force vga console preference"

Though only once, after next reboot, it fails:

for x5-Z8330 i915.modeset=1 changes nothing:

next try: I removed i915.modeset=1 on N5105 and this time it started:

-1

wow, this error happens when no monitor is connected (x5-Z8330 in my case) or it's suspended (N5105)

and here's why rebooting helped

chvt 1 / chvt 7 also makes it work

532910 commented 2 days ago

with Matrox G200eW it works even with no monitor connected
