Xorg, mesa, libdrm

Xorg, mesa, libdrm

[Andreas Enge]

I just came across these lines in the new package xf86-video-modesetting:
    (inputs `(;; FIXME: This is a libdrm version incompatible with that of
              ;; MESA, which xorg-server uses.  Therefore, using this driver
              ;; leads to "unresolved symbol drmModeSetCursor2".
              ("libdrm" ,libdrm)
Could we not simply use libdrm-2.4.33 as in mesa? The same should hold for
xf86-video-intel. Or probably better yet, as in the other xf86-video-*, 
use mesa as an input.

No, this driver requires the latest libdrm.

The long-term solution will be to use the same one in MESA, but I’d
rather not do it too close to the release.  :-)

Thanks,

And the intel driver? I think that may have been my mistake in the first
place to not use mesa.

Yes, update to a newer mesa - but they have this unpleasant infinite
configure loop.

I pushed after swapping libdrm with mesa. It still compiles, at least.
