When I right click a file with my file manager, I am unable to take a screenshot.
Other print screen attempts do work.
Is there a fix?
It is absolutely normal.
In such case I use delayed screenshot as follows:
mate-screenshot -d 3
above -d
is for
-d, --delay=seconds Take screenshot after specified delay [in seconds]
and 3
is 3 seconds delay. You can use this delay for doing right click.
