I'll check this on an amd64 machine, i think i have one that also needs -p -s, but IIRC this worked. Something worth a try would be to use plain vbetool (there is also a newer vbetool available for ubuntu than the code base included in s2ram) if it happens there also. The "Get video state buffer size failed" adn "base is 0x0" looks suspicious to me. So if "vbetool vbestate save > /tmp/foo" works on this machine, but s2ram fails in __save_state, something is wrong with s2ram... -- Stefan Seyfried | "Please, just tell people QA / R&D Team Mobile Devices | to use KDE."
