It seems to me, that a plain freebsd r315141 does not resume completely. The display is still staying black after resume but the laptop is acces= sible via ssh.=20 2. After installing xorg and starting X on r315141, resume works correctly.= =20 Not having a running X results in not resuming the LCD. 3. setting the value hw.acpi.reset_video=3D1 results in continously resetti= ng the machine. Only pressing the powerbutton for a long period of time di= srupts this cycle. 4. r317559 with X running does not suspend at all. Stopping x and try to su= spend then results in similar behaviour as described in 1.
