Q: Why are the VAST Transcript icons black and white?
Problem
When I launch Vast Platform (VA Smalltalk) on Linux, the icons on the transcript are black and white.
Explanation
The black and white icons show up on some Linux platforms where Wayland instead of X Windows is used to display the user interface. Although Vast Platform (VA Smalltalk) displays well under these general conditions, specifics the configuration lead to the black and white effect.
For some combinations, like Wayland-powered Ubuntu 19.10 or OpenSUSE and GNOME, The VAST IDE icons appear in color. For others, like Fedora 28, the icons are shown in black and white.
If you have a virtualized Linux operating system, and you are using Wayland to display the user interface, enabling ore disabling the 'Accelerate 3D graphics' in VM guest display settings changes what drivers are loaded. Disabling results in the vast IDE appearing gin color. Enabling results in icons show in black and white.
Solution
You can disable Wayland. Once you use X-Windows, the icons will display in color.
To do so .take the following steps to revert to X.
Edit /etc/gdm/custom.conf file
Comment out the line
# nano /etc/gdm/custom.conf
And uncomment those lines
# GDM configuration storage
[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false
Another possibility is to leave Wayland enabled, but to disable 3 D graphic acceleration.
