--- Comment #7 from Elmar Stellnberger estellnb@elstel.org --- Comment #6 is now resolved: Please excuse the panic; I think that there was just a temporary configuration issue with Arch Linux (see also: https://bugs.freedesktop.org/show_bug.cgi?id=93405); i.e. /dev/card0 needs some time to appear; now let us go on with the s2ram issue as the issue with enabling the monitor after boot is already resolved!
