Thanks everybody for reading my first post.


On booting I can hardly take a photo of errors in loading system.

Is there a way to slow all process in order to read single lines ?

I am writing down some lines :

[ 1.57636 ] i915 firmware failed to load ...
.......

[ 5.666105 ] usb cannot get freq at ...

..........

Some errors are at beginning, others at the end of long list , showed
very quickly.

I am using Debian Bullseye , system works. (For internet surfing, writing, printing). There are still problems (as reported above ) to solve.

Use journalctl after logging in to view messages produced during boot.

You should find Xorg.0.log either in /var/log/ and/or ~/.local/share/xorg/ to find some specific to Xorg error messages. Share the log this way, e.g.:Provide here the URL resulting from that command. Also paste here using code tags the input/output from:

Thanks for your answer, beyond my expectations.

I upgraded to debian 11 (but .. with problems : you may see on root I am still on Debian 10 ! )

Up to now ''using code tags'' not clear to me . . How to use them ?

R.E. using code tags:
<CODE> insert here the output from the former command 'sudo inxi -SGayz' </CODE>
Have a great day. Peace

Did you open the using code tags link I provided in post #2? There's an icon # above the input window to click on once you've highlighted what you wish enclosed in them. Or you can simply type the tags [code] to start & [/code] to end.

Looks like debian 11 (bullseye) to me? Although your hostname is debian-10.... but you picked that.

Many thanks to all members for explanations. By means of your help I noticed non-free firmware were missing.
Now my computer works much better.

Minor (may be equally important) questions in separate posts.

I also learned how to use ''codes'' as below :
