I'm using this for kiosk type work, so no window manager. I just start X with the following line in the inittab (same line I used in previous FC5 builds that all work normally):
nce:su --login --command xinit codec >/dev/null 2>&1
However, to go ahead and anticipate the next question, I went ahead and changed the line back to the original stock fc6 line:
And then telinit 3 and 5'd the system, logged in through gdm, and checked the situation again. Still no XVideo and still no DPMS.
Is there a package during the FC6 install I might have missed that is needed for the nvidia module to support dpms and xvideo which is not needed by nv to to do the same?
