Xubuntu has been my go-to so I installed 23.04 on both my wife’s new computer, her netbook and our htpc recently. Turns out it ships with a broken xfce4-screensaver that crashes when you try to unlock the computer and you get stuck (unless you switch to a virtual console and kill the process). A xubuntu dev was helpful and directed me to a ppa that had a patched version, but I was still surprised that such a central feature wasn’t working.
In addition there appears to be some kind of screen blanking that I haven’t been able to disable. At first I just turned off the screen saver and all power saving features in the control panel, but the htpc would still turn off the monitor if left alone for some time, and then refuse to turn it back on unless I switched back and forth between virtual terminals while the TV was turned off. It got a little bit better after uninstalling xfce4-power-manager, and now the screen can be woken by moving the mouse, but it shouldn’t turn off at all since it’s supposed to be disabled.
I hope they manage to sort all those things out. I used Xubuntu for 5+ years with almost no issues.
