Warzone 2100 Forums

Xlib: extension "RANDR" missing on display ":0.0".

I would like to have that ignored as a build option. I've played warzone for years using 2 nvidia cards and 4 monitors using xinerama. It hasn't worked for months now giving me that error. Can I defeat that?? Thanx for all the good work!

We've been linking against Xrandr for a very long time (unconditionally since 2011), so no idea why it should suddenly stop working now. Did you upgrade Warzone? If so, which version last worked?

I've kept all of my builds since back when, they all stall now with that error. Including the latest. I'm running Ubuntu 17.04 (zesty) 16 gigs of system ram, 4 gigs video ram with two nvida GTX 750ti cards using nvidia driver 375.66 and xinerama. No clue. We had this problem in the past but it was "fixed" somehow. Thanks for all you do. Ric

You can try to change the line

X_LIBS="-lX11 -lXrandr ${X_LIBS}"

to

X_LIBS="-lX11 ${X_LIBS}"

in configure.ac and recompile, see if that helps.

I got the same error again, but at least we know it is not from the edited code. I wonder if qt is a problem?? Ric

From what I have googled it is more of a display problem with qt5 when it was upgraded from qt4.
