In commit f175cf45aebcdda53f3ae49c0eaf27da1f194e92 Author: Olivier Fourdan <ofourdan@redhat.com> Date: Wed Feb 10 09:34:34 2016 +0100 vidmode: move to a separate library of its own the verbosity of some old debug messages (which print the reply to every GetModeLine client request and others) was increased leading to lots of log spam. Downgrade the logging back to DebugF.

2016-03-01vidmode: build without xf86vidmodeprotoOlivier Fourdan1-0/+4
git commit f175cf45: vidmode: move to a separate library of its own introduced a regression where the xserver would not build when xf86vidmodeproto is not installed even if the configure option "--disable-xf86vidmode" is specified. Fix build failure when xf86vidmodeproto is not installed. Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>
2016-02-29vidmode: move to a separate library of its ownOlivier Fourdan1-0/+2147
XVidMode extension might be useful to non hardware servers as well (e.g. Xwayand) so that applications that rely on it (e.g. lot of older games) can at least have read access to XVidMode. But the implementation is very XFree86 centric, so the idea is to add a bunch of vfunc that other non-XFree86 servers can hook up into to provide a similar functionality.
