Thank you for the explanation :)

I had a stressful week with setting up Linux and I'm not ready yet, but
the only thing I didn't get working is the mouse. I replaced it with an
USB mouse, anything else does work. Now I only need to set up
nonessentials.
Most things seems to work better, than they have ever worked before.
Regarding to the Internet it could be issues caused by my provider, I
don't know.

The computer now seems to be in a good shape and my systolic blood
pressure was at 154 in the morning and is at 142 now ;), if I reach 139
Linux and I are ok again. Oh, this is for the imaginary OT blog.

I did expect trouble with audio, but not with anything else.
Still euphoric, but not pissed of.

My impression is that audio reached a very high quality state, but that
the environment, desktop, X etc. might do a small step in the wrong
direction, but at the moment I'm unable to see it dispassionate.

Hm, ok, time to stop writing OT, but I liked to reply.

Should do a backup now.

Best,

Ralf
