Ok, Thank you, I downloaded the sources for x-on-resize [1], got it to
compile with clang, but I do not receive events.
Clang line:
clang -v -L/usr/X11R6/lib/ -lX11 -lXrandr
-I/usr/src/lib/libX11/include/ -I/usr/src/proto/xorgproto/include/
-I/usr/src/lib/libXrandr/include/ -I/usr/src/lib/libXrender/include/
x-on-resize.c
I modified the source a bit to get some output:
```
for (;;) {
int configed = 0;
int resized = 0;
printf ("in for\n");
do {
printf ("in while\n");
printf ("XNextEvent\n");
XNextEvent(dpy, &ev);
printf ("ev.type: %d\n", ev.type);
switch (ev.type - event_base) {
case RRNotify:
printf ("in RRNotify\n");
nev = (XRRNotifyEvent *) &ev;
```
But I only get "in while", then "XNextEvent" and nothing more, it sits
there. If i execute Xrandr, change Xrandr configuration, disconnect
HDMI port, reconnect HDMI port, I do not receive any events.
Does any one have any thoughts? Could it be my graphics card?
