I fresh installed ubuntu 20.04 today and found the alt+mouse drag for move and ctrl+mouse drag for resize doesn't work. How can I turn the function on? (I don't know why ubuntu people didn't set it as default).
ADD : I found under setting-keyboard short - windows, the default window move is Alt+F7 and window resize is Alt+F8. I want to change it to Alt+mouse and Ctrl+mouse which is quicker. How can I change it? (I tried but didn't work)
Someone thought that changing the key to Super was a good idea to resolve some other conflicts for the design crowd. Frustrating. To restore the Gnome 2 defaults of Alt:
If you want to use Ctrl then you can substitute
<Ctrl>
above, but I think you might be mistaken, chances of conflicting key combinations involving that are even higher.
