Video working after a hibernate/thaw cycle is the usual thing -- the BIOS fully reinitializes the video hardware when you boot the system to wake up from hibernate, so we don't have to with the various quirks. > - s2ram and pm-suspend from X work *only* when resuming from hibernate Hmmm... I am not parsing this correctly. Are you trying to say that you are able to suspend/resume using s2ram or pm-suspend only after a hibernate/thaw cycle, or something else? > Invoking s2disk or pm-suspend on a normal boot seem to suspend the laptop > correctly > but on resume, no matter what quirks I try, laptop is freezed with blank > screen and no > keyboard control.

Hmmm... vanilla pm-utils does not use S2RAM_OPTS.

Do you have some hints? pm-hibernate and s2disk don't do any handling of the video card at all by default. > Thanks, > leonardo > > PS is posting allowed for suscribers only?
