Package: hibernate Version: 1.94-2 Severity: normal Tags: patch I have a new approach for getting suspend to ram working on my p7120 lifebook. Stockholm suggested that simply dumping a file from proc before suspend and loading it afterwards worked better than using vbetool (which fails to turn the backlight back on on this laptop). I believe that the /proc file contains the first part of the video memory, so loading it resets the video card to the pre-suspend state. Or destroys your machine, if you're unlucky, but it works well for me. ;-)
I've attached a scriptlet I wrote to do this, and it can be enabled as
follows:
# Dump video card memory. If vbetool doesn't work this just might. Or it
# might hose your machine, so use with caution. Do not enable this
# option and Vbetool at the same time.
EnableVideoDump yes
(PS, is the s2ram -n in the info below supposed to print the help text?)
