Q: Why is the Defold editor super small when run on a 4k or HiDPI monitor when using GNOME?
A: Change the scaling factor before running Defold. source
$ gsettings set org.gnome.desktop.interface scaling-factor 2
Q: Why does mouse clicks on Elementary OS go through the editor onto whatever is below?
A: Start the editor like this:
$ GTK_CSD=0 ./Defold
Q: Why does the Defold editor crash when I try to create a new project, or open an existing one?
A: On certain distributions (like Ubuntu 18) there is an issue with the version of jogamp/jogl Defold uses vs. the version of Mesa on the system.
See the following reports for more information:
- https://github.com/defold/editor2-issues/issues/1905
- https://github.com/defold/editor2-issues/issues/1886
If this is your problem try the following workaround:
$ export MESA_GL_VERSION_OVERRIDE=2.1
$ ./Defold
And if that doesn't work then try (or some other version number matching your driver and larger than or equal to 2.1):
$ export MESA_GL_VERSION_OVERRIDE=3.1
$ ./Defold
Q: Why am I getting "com.jogamp.opengl.GLException: Graphics configuration failed" when launching Defold on Ubuntu 20.04?
A: On certain distributions there is an issue with the new Mesa drivers (Iris) when running Defold. You can try using an older version when running Defold:
$ export MESA_LOADER_DRIVER_OVERRIDE=i965
$ ./Defold
Q: Why doesn't my Defold game start when I try to run it on Linux?
A: Check the console output in the editor. If you get the following message:
dmengine: error while loading shared libraries: libopenal.so.1: cannot open shared object file: No such file or directory
Then you need to install libopenal1. The package name varies between distributions, and in some cases you might have to install the openal and openal-dev or openal-devel packages.
$ apt-get install libopenal-dev
