ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded

Found the answer after a bit of web searching here: https://github.com/PX4/Firmware/issues/9409

Solution

If you update your .bashrc with the below line it should fix the issue:

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0

In addition, you may need to install the following package:

sudo apt install gtk3-nocsd

Another user reported installing the following package fixed their issue:

sudo apt-get install libgtk3-nocsd0:i386

Running

$ sudo grep -r LD_PRELOAD /etc $HOME

I found lots of configuration files of the removed package gtk3-nocsd like

/etc/X11/Xsession.d/51gtk3-nocsd-detect: export LD_PRELOAD="libgtk3-nocsd.so.0${LD_PRELOAD:+:$LD_PRELOAD}"

Just remove those old configuration with:

$ sudo apt-get purge gtk3-nocsd
