Is there any possibility to get OpenChrome to support 1920x1080 via
DVI/HDMI on a VX900 (I'm using the latest trunk from git)?
I've got a Zotac ZBox VD01 wit a VX900 nd a 1920x1080 TFT connected
via HDMI. 1440x900, 1400x1050 and some other resolutions are
working perfectly when I use the ForcePanel and the PanelSize options,
however 1920x1080 doesn't work. The card seems to try to set the mode,
the TFT doesn't switch into standby mode (as it would when
trying for instance "1680x1050"), but it stays all black nonetheless.
I've aleady tried adding the mode (both correct resolution and panel)
to ViaResolutionTable[] in via_mode.h, but without success... :/
Any hints?
Thanks to schlobinuxes help in IRC, I've got 1080p to work via HDMI.
You need to use openchrome-drm from git (so essentially, you have to
build the whole kernel unless you're already running some Linux 3.9
RC). 1080p also works with KMS enabled (via.modeset=1 in cmdline), but
with KMS enabled, there's no XV support and (as schloblinux explained)
just very little 2D acceleration (it's fast enough for "standard office
work" though).
Just a note, you need the drm-openchrome kernel, not a "standard"
kernel, even 3.9 rc, nothing has been included in upstream kernel yet.
There are a couple hints on KMS there :

Thanks for the great efforts all of you are putting into this driver
anyhow. You folks are terrific! :)
Thanks for testing and reporting back :-)
