I'm using the nv.o driver. Perhaps nvidia's driver handles it > right, dunno. Aha, so you do not have s2ram from suspend.sf.net installed, do you? Restoring the screen is done by either a) kernel/bios (acpi_sleep=..., or better s2ram -f -a X ) b) vbetool c) X . s2ram should detect your machine, and automatically set acpi_sleep and/or perform vbetool magic. Please try s2ram, there's good chance it will just work. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
