I want to use the native resolution (854x480) of my BenQ PE5120 beamer.
I generated this modeline
ModeLine "854x480" 45.86 854 896 1096 1176 480 482 494 520 #75Hz
which seems to work in Xorg's nv-driver, but then I don't have 3d-acceleration and somehow the beamer never registers a change in the resolution (it always reports it at 1024x768).
When I use the nvidia-driver (1.0.7676 and 1.0.6629) I get this message in my /var/log/Xorg.1.log:
(WW) NVIDIA(0): Not using mode "854x480":
(WW) NVIDIA(0): horizontal resolution (854) not a multiple of 8
(WW) NVIDIA(0): horizontal blanking width ((max(1176,1096) - min(854,896) =
(WW) NVIDIA(0): 322) not a multiple of 8
is it possible to disable this multiple of 8 check or does anyone know of another way of using this resolution?
