So at this point your environment should be active - type qgis in the
terminal and it should start.
I ignore the ICD warning. I think at some point I actually installed
something to make it go away but it doesn't stop qgis from working.

Soooo,
I thought to share my steps so far, so I will not have to ask again in
some weeks ;)
terminal:
$ curl -L -O
"https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname
-m).sh"
bash Miniforge3-$(uname)-$(uname -m).sh
was asked to deactivate the base environment and confirmed, but
somehow this did not happen, so:
$ conda config --set auto_activate_base false
$ conda create --name qgis_3.34
then I got warned that there is a newer version of conda (strange, why
isn't the new version installed right away?).
So done as told:
$ conda update -n base -c conda-forge conda
$ conda activate qgis_3.34
conda install qgis=3.34
stuff is installed, but again the warning to update
finally:
WARNING: No ICDs were found. Either,
- Install a conda package providing a OpenCL implementation (pocl,
oclgrind, intel-compute-runtime, beignet) or
- Make your system-wide implementation visible by installing
ocl-icd-system conda package.
That stuff is exactly what I was messing around with for the past week
to get the graphics card support in QGIS. Gnrrr...!
So, what to do now? I feel like panicking ... ;)

Don't feel dumb, it is all written and spread out in super
complicated ways but once running, it's alright-ish.
Normal Miniforge3 should be fine unless you know you want pypy.
Unless you know differently, try the "Miniforge3-Linux-x86_64" version.
Mamba is something hidden in the background, for you it will pretend
to be Conda. Conda is the original project, mamba is a faster,
compatible alternative.
Miniforge is something that comes with mamba "as conda" and
automatically uses the big "conda-forge" repository where lots of
software and libraries are available, packaged by the community.
You can use the command lines from
https://github.com/conda-forge/miniforge?tab=readme-ov-file#install
After installation I recommend: $ conda config --set
auto_activate_base false
Otherwise every terminal/shell session will run using a conda
environment instead of your standard system environment.
Once installed, you can use the "create" line from other previous
mail to install a QGIS environment. Then "conda activate qgis_3.34"
to activate it in a terminal session, "qgis" in that same terminal to
launch that QGIS and just close the terminal or enter "conda
deactivate" to deactivate it again.

Hi Hannes,
Thanks for you answer. I played around before with those snakes and
that's what maybe brought me into trouble.
And again, this zoo of species starts to confuse me, starting with
the installer:
Miniforge3 or Miniforge-pypy3 ?
And when does the mamba come into play instead of the conda?
Sorry for me playing the dumb, but I almost spent a week trying to
get things back to normal here at my desk.
Cheers,
Bernd

Hi Bernd,
a pragmatic solution which I have grown to like is using conda
environments. Using mamba instead of the default conda via
https://github.com/conda-forge/miniforge to reduce annoyances and
then it is for example a simple "conda --create qgis_3.34
qgis=3.34" to get a nicely isolated QGIS 3.34 with pdal etc.
Just make sure to deactivate the base environment in your
terminal/shell, otherwise you are trading one potential mess for
another ;)
Cheers, Hannes

Hi,
using QGIS on the "normal" ubuntu-based Linux Mint for years, I
again managed to render my system unusable by playing around too
much, resulting in ever crashing QGIS so I even had to reactivate
a Windows Virtual Box to be able to work!!
After a hell of problems with NVIDIA graphics drivers (opencl
support in QGIS), I finally managed to get everything to work with
Linux Mint Debian edition ... but now had to learn that Debian
does not provide PDAL for point cloud stuff in the repositories.
Long story short: Can anyone give me recommendations how to get
PDAL working with QGIS that do NOT include building PDAL and QGIS
by myself?
Though I USE Linux for over 15 years,I would prefer avoiding that.
Fumbling around with too less insight on what I am actually doing
just led me here...
Cheers,
Bernd
