Any software in Linux can be used in education, as long as the schools invest the time:

• LibreOffice can create really nice documents and presentations too. Heck, some tasks are more straightforward in LibreOffice than MS. 99% of schoolwork is done in Office suite, so this is nice. Win for Linux

• For stuff like coding in C or Python, it is even easier in Linux: download a compiler, open a text editor, type some codes then use terminal to run the codes in 10 minutes. In Windows, you need to download the stupid Cygwin and mess around with environmental variables to get Cygwin to recognize the libraries… Or if you want to automate things, MS Visual Studio will do that. The only downside is you will lose > 10 GB of space. Linux wins here again.

• Anything more advanced will unfortunately Windows land. I’m talking about advanced image programs like Photoshop or professional video apps. But again, if you need them then might as well get a Mac. Another hiccup would be in CAD software: Linux just doesnt have a good app.

Hmm let’s try to isolate the bug to know if it’s sway or gdm messing up:

Try to disable gdm: sudo systemctl disable gdm.service

Logout/restart. You should be at the TTY, enter username and password to login. Then simply type sway

Now, test your sudo commands within this sway session. Do you still get the same bug?
