Resuming From Suspend on a Dell Latitude D400
Resuming from suspend on a Dell Latitude D400 does not work out of the box in SLED 10 SP1. When you try to suspend a dialog pops up saying you have to force it, and when you do, the video card isn’t initialized correctly when the laptop comes out of suspend.
Edit /etc/powersave/sleep with your favorite text editor (such as gedit, vi or nano).
Set SUSPEND2RAM_FORCE="yes" and set SUSPEND2RAM_VBE_POST="yes"
Then restart powersaved with ‘/etc/init.d/powersaved restart
Suspend to disk and suspend to RAM now both work perfectly 🙂
SLED 10 SP1, brand new clean install. Tested this on two different Dell Latitude D400s (mine and a friend of mine)
