- The login page (gdm3) does not detect when I touch the touchpad. I need to press it hardly to get a click. I read somewhere that it is a feature for tablet-like devices.
- For some unknown reason, gdm3 is listening for click events. As a result, I cannot use my touchpad in i3. The only fix I've found is to install Xubuntu. So I end up installing Ubuntu, i3, and Xubuntu in that order. The login page of Xubuntu (lightdm) does not mess with the touchpad in i3. You can say, just install lightdm alone. However, that does not work, though.
- Regarding snaps, my only complaint is the file dialogs of Firefox (file chooser, save as...) in i3. Again, some process is capturing events. Every time I want to type a file name when saving a file, the dialog instead trigger the autocomplete menu. So instead of typing the name for saving the file, the dialog shows me file matches. Very annoying. That only happens in i3.
