Thanks for the tip, I've tried that, unfortunately without success. I'm going to describe, what happens, when I suspend and resume and I would be glad about every help. My laptop is a Samsung X30 with nvidia geforce fx go 5200 vga-adapter. - Booted normally to console (no framebuffer, no X), only module loaded is evdev. - saved vbestate: # vbetool vbestate save > path/to/vbefile - # sync - suspend to ram: # echo -n mem > /sys/power/state === Now the Laptop properly suspends! === - wake up the laptop by pressing the appropriate button, now display stays black but I can type commands blindly - # sync - try to post video-bios # vbetool post === Now the screen turns white with strange couloured lines. The white screen slowly gets darker and darker... I took a photo: http://bugme.osdl.org/attachment.cgi?id=4029&action=view - # vbetool vbestate restore < path/to/vbefile has no visible effect :( Switching terminals and starting X works (according to the logfiles), but has no effect on the display!
