Followup-For: Bug #978192 Control: reassign -1 libxnvctrl-dev Control: affects -1 + src:xfce4-sensors-plugin
NVCtrlLib.h uses macros from X11/Xlib.h but does not include that header. So including NVCtrlLib.h only worked if X11/Xlib.h was accidentally included earlier, which no longer is the case: rebuilding xfce4-sensors-plugin/sid fails in sid and bullseye, but works in buster. In buster the include chain was /usr/include/xfce4/libxfce4panel-2.0/libxfce4panel/xfce-panel-macros-46.h /usr/include/gtk-3.0/gdk/gdkx.h /usr/include/X11/Xlib.h but in bullseye /usr/include/xfce4/libxfce4panel-2.0/libxfce4panel/xfce-panel-macros.h no longer includes gdkx.h And nvidia.c itself includes NVCtrlLib.h and X11/Xlib.h in the wrong^Wunlucky order.
