Description of the issue (you can include screenshots): In Windows 10, the same tablet is working fine. But when I use with Ubuntu 21.10, every stylus drawing is very very light. Is there anything I can do to fix this? Thanks.
The obvious questions are: Are you using the same brush preset each time?
Which brush preset is it? (Try testing with Basic-2 Opacity or Basic-5 Size.)
With Windows, have you adjusted the tablet driver settings utility to vary the pressure response curve in any way at any time?
In Windows or Linux, have you made any changes to the Input Pressure Global Curve?

These include the pressure signal P=xy.z%
You should be able to easily make that signal go from a very low value to 100% in a controlled way by varying the stylus pressure. e.g:
