The drawing mode provided by zoomit is wonderful during a presentation. Is there any software on Ubuntu that provides the same functionality?
You might want to give Gromit-MPX (which I authored) a try:
Gromit-MPX is an on-screen annotation tool that works with any Unix desktop environment under X11 as well as Wayland.
It's hotkey-based so there are no widgets in your way. Also, you can configure colors, mouse button mappings and hotkeys. No zooming though, only annotations. Go here for details.
You can install it through Flathub.
If you have Ubuntu, you should have
compiz, so use
compizconfig-settings-manager to turn on some plugins. This manager is in
software-center with plugins too.
When you will have some problems with crashing of compiz because your testing, install
fusion-icon to quick reloading it.
compizconfig-settings-manager can be launched by command
Annotate (under Extras): Drawing on the screen.
Enhanced Zoom Desktop (under accessibility): Does that zoom.
Set-up shortcut as you like and enjoy. :)
In Linux Mint KDE there are:
Meta= to magnify
Meta- to reduce magnification
Meta0 to go back to normal
They are under KWin shortcuts in settings.
I understand that is no ZoomIt, but I haven't found anything close. Most software is just a window showing a magnification which is quite useless during presentations.
I understand that it's not Ubuntu either but, it's close and maybe Ubuntu has similar settings.
