I am learning something through this effort of making these isos available to users. They were introduced here. The first post stated:
These ISO’s are labeled Alpha mostly because LXQt desktop has not had a lot of testing.
The LXQt isos were not meant for people to use for production work they were meant as a test to see if they worked. So in the sense that it boots and installs it works, but the desktop has enough problems that most users won’t use it. There are people in developer group looking at this.
We thank all of you that reported problems with the LXQt Rolling isos. And there were significant issues. We thank all of you for reporting that the isos boot and install.
The main bug from user perspective is that the task manager does not work as reported by @epp and also here and here. The user configs reported here are very easy to workaround. But we would certainly want those fixed before releasing any LXQt iso for production use.
Apologies for any inconvenience or confusion.
Note: KDE Plasma 5 is the officially supported desktop for OMLx. As far as I know at this time all other desktops are alternative desktops. Using an alternative desktop for production implies that you can deal with problems that may arise.
