[Pkg-tigervnc-devel] Bug#929410: RANDR extension not present

[Floris Bos]

Package: tigervnc-scraping-server

Version: 1.9.0+dfsg-3


Seems the tigervnc package is missing randr support.

$ x0tigervncserver -SecurityTypes none

Wed May 22 22:20:30 2019
  Geometry:    Desktop geometry is set to 1024x768+0+0
  XDesktop:    Using evdev codemap

  XDesktop:    XTest extension present - version 2.2
  XDesktop:    RANDR extension not present
  XDesktop:    Will not be able to handle session resize
  Main:        Listening on port 5900
^C

While my system/X server certainly has the RANDR extension:


==

$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 7680 x 7680
HDMI-1 connected primary 1024x768+0+0 (normal left inverted right x axis 
y axis) 0mm x 0mm
    1024x768      60.00*
    800x600       60.32    56.25
    848x480       60.00
    640x480       59.94

Think you are missing a build dependeny on the libxrandr2 library.

If HAVE_XRANDR is not set at compile time, it always prints the message
