Thanks for your answer.I am on 21.04 Xorg and it's ok
I hope that This Gamma treatment will appear on The next ubuntu Wayland version. Especially on The 22.04.
xgamma and xrandr control the 'Xorg' process. There is no Xorg process
in a Wayland session so xgamma and xrandr will not work. That's not a
bug. If you need them then you should log into 'Ubuntu on Xorg' instead.
** Summary changed:
- Ubuntu 21.04 No alarm when Battery under 10%
+ Ubuntu 21.04 No notification when battery under 10%
