My 5 year old grand-daughter likes playing with tux paint on her pc (peppermint 3), the program works fine however when she’s in the tux paint screen an annoying box floats around the screen saying input not supported, I think this is coming from the monitor but it only occurs in that program,
has anyone any idea how I can sort it, any help would be much appreciated
It could be down to the mismatch in resolution (which your monitor cannot handle)
Try creating ~/.tuxpaintrc in the home folder to override the defaults:
gedit ~/.tuxpaintrc
Add the following line:
fullscreen=native
Run the program in full screen mode. Additionally, it will assume the screen’s current resolution (set by the operating system).
