I don't know with 22.04 and with the current, but on the first XPS developer models (I believe 9370 and 9380), there was an issue with the power consumption in standby mode, which required a workaround. Tracking bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808957 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808957. It's a bit mad - even if the fix has been released, it seems to still affect users of other XPS models. Other bug, affecting keyboard lights: https://ubuntu-mate.community/t/keyboard-light-keeps-turning-on-after-login-and-or-unlock/6914 https://ubuntu-mate.community/t/keyboard-light-keeps-turning.... On the other hand, the recent XPS 13 Plus, is officially certified by Ubuntu, so there's hope :)
