I’ve tried to add ScreenShots using file:// but I don’t think this will be a successfully embed.

Upload screen shots (and very long listings) to https://susepaste.org/.

I think you do not need to upload screen shots. Your two commands show what you mean.

  • dmidecode shows 4+2+4+2=12 GB.
  • free shows 3.4 GiB.

Thank you all so much for showing interest in helping with this issue. I just went in to the BIOS to enable fan control to stop them from going all full blast all the time, and after rebooting and booting into the desktop I noticed the memory now is

Strange but not sure why, possible theory a hard reset etc. I also looked into kernel memory Parameters, added “cma” (without the quotes) into GRUB commandline (got an error though as it requires a string i.e. =“”). and Was going to experiment with another parameter known as mtd (memory technology device).

But anyways, in the meanwhile the systems quite zippy at this stage flipping from a window to window even on seperate desktop/workspaces is just smooth. I’m going to enjoy that, for the rest of the day. and then perhaps tomorrow (Saturday) will see if entering in to the BIOS kinda solves the prob or something.

Ok, thus for the moment we can treat this as solved I assume.
