cannot set the DRM interface version
cannot open a connection with the DRM

from xorg-docs
ReleaseNotes.html:323: Of note is that this release supports building the X server using
ReleaseNotes.html:324: the system-wide libdrm. Previously, drm was kept in the server's
ReleaseNotes.html:325: tree and loaded as a module, rather than using the standard OS
ReleaseNotes.html:326: mechanisms for managing shared libraries of code. This requires
ReleaseNotes.html:327: that the server be built using a version of libdrm of 2.3.0 or
ReleaseNotes.html:328: newer if it is to use DRM.

is this going to cause a lot of work?

Is this back far enough?

Have you installed those two packages?
xf86-video-armsoc-rockchip
veyron-libgl

[WarheadsSE]

Check the permissions, or use something like lightdm

[taoist]

k -- the 2 packages are installed.

w -- lightdm has the same problem... I'm setting this up as root.

xdm actually gives me graphics, but doesn't accept root/root as a login. I'm going to research that.

This is what xdm reports.

[taoist]

xdm requires a root startup and a user login... and crashes anyway.
It fails looking for some key authorization. I know: wrong forum. fyi

[taoist]

Other then xdm, I still have the DRM problem interfacing with X (build date 5 Apr).
