Linux?

Still trying to wake up a ten year old laptop, possibly having motherboard issues (and with DVD and maybe even with Graphics card, but these might all be related to one corruption in the chipset, maybe?)

Some humor inserted, many of the 'star names' might be in wrong places and might have totally forgotten about some. Distrowatch says I forgot about (2021.08.21) Endeavour, Solus, KDE neon, antiX, Puppy and Kali, but it's possible there are some more. (Addition:FreeBSD should probably be somewhere right of the constellation β Gru?, as it tries to do much in direct binary, like unix, Linux is more lenient in the use of programming languages i guess.) Various free operating systems have stable and rolling releases, that is, those that are tested more and updated not too frequently, and those that are receiving updates frequently, but on occasion might cause issues. Once a rolling release is rolled far enough away from the release it started people might give it a separate name, so there are probably other popular releases about if you read this far im the future. 

Anyway, the look and feel of a Free OS depends much on the Desktop Environment it's using.  Some distributions allow systemic changes only through the Command Prompt, while this is a good precautionary method to prevent the user to do harm to important System Files, many commercial OSes have much prevented the user to touch these files almost wholly (if the user is not a professional). At least the few Free OS systems I've checked use the master password user himself has set to allow changes in the System Files. Just remember not to touch files outside your home directory, if you're unsure what you do. Of course if you want to change the system in some way, f.e. to run some programs not within the Free OS point and click system, you have to go there. Some distributions have point and click menus for some settings, but not all mac and windows programs will run their installation programs on Free OS, nor install properly if they do run. Ask the program vendor about a version that could run or use an alternative. Sometimes an older version of a program might run on another OS.

Mind you, the 'constellation' presented is only visible totally from quite southern latitudes. (~20N southwards). The stars belong to several existing constellations Ara, Pavo, Octans, Tucanae, Indus, Telescopium and few additional stars. The Penguin stares ~ South Pole. The moon never goes as near of the South Pole as the penguins eye.
