You're spot on, that does the trick. # cat /sys/module/nouveau/parameters/agpmode -1 # cat /sys/module/nouveau/parameters/runpm 0 v3.13-rc1-95-gb975dc3 + http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=0397aaaa009092427dc60aea8b3c21c00526d8ba + nouveau.runpm=0 is now stable, with and without a monitor attached; as is 3.12.1 || v3.12.1-62-g4615252 (stable-queue.git) + nouveau.runpm=0 I don't need to override the agpmode parameter. Thanks a lot! Regards Stefan Lippers-Hollmann
