1. On the laptop with Intel graphics card, when i915kms is loaded, vt
resumes without problems. On the laptop with the ATI graphics card
(Radeon HD 8240), I use vesa driver at the moment, and it does not
resume the screen.
2. I wanted to make sure, that the problem has nothing to do with my
local system settings, so I dd'ed 10.1-RC1 image onto memory stick,
added `kern.vty=vt' to /boot/loader.conf and booted both laptops with
it. After they started, I suspended them, tried to resume and there was
the same problem: blank screen, but system seemed to be
running. (syscons resumed properly with the same method. There were
problems with the USB stick and root partition, but I think that's
normal and irrelevant.)
Thank you!
