ok, it seemed the very first thing to do would have been

sudo apt install -t beowulf-backports linux-headers-amd64

but in my case it was already installed , maybe because i had installed the "Nvidia-Linux ..run" previously or maybe installing "nvidia-driver" via backports installed those aswell?

@GlennW , thank you, i tried your method, and it brought me a functioning desktop. However there were some error messages, one notably

on beowulf i had to first fix pulseaudio , dont know if this sitll applies

@yes, it is functioning, but i would like still to install driver package, for better options etc. also duplex is otherwise sometimes greyed out.

hello,

i am having the same problem.

is there a solution yet?

it happens after coming back from suspend; if i just disconnect the ethernet cable and reconnect, nothing happens, and wicd manager shows no ethernet connection at all.

my ethernet seems this one

       product: 82567LM Gigabit Network Connection

sorry, but the camera shows only "USB-Mode   PTP/MTP"
                                                      "Speicherkarte - Wiederg. per "Wiedergabe" - Tastendruck" eg. "Memorycard - Playback via "Play" - Buttonpress"

if playbutton is pressed, the only think happens is that the internal display on the camera is being changed from the above message/statusscreen to the active fotomanager on the camera, eg. the photos are being displayed on-cam.

lsblk is giving the following output

will check the next days on ubuntu after iget my cmputer back to see if it behaves there differently, but i believe so.

hmm, strange, the sony mp4 player gets recognized and is shown in file manager xfce , the camera however not.
will do some more testing.
thanks for your help.

i have upgraded the system on the laptop from Ascii to Beowulf, but that should not make a difference in recognizing the Camera;

the update process proceeded without any errors,

Thank you very much.

@head_on_a_Stick, thanks, good suggestion.

@blackhole, yes, probably unsupported, as i just installed devuan beowulf anew (with nividia 1650)
and it would not go into "X"; so i was greeted with terminal window instead;

installing

nvidia-driver

does not resolve, well at least it gives a graphical desktop, but blocks the terminal thereafter with "nvidia-persistenced".

if i need backports, i will try those.

EDIT: tried also installing the drivers from bakcports,
i am still getting "nvidia-persistenced" error.

please someone write a small guide on how to properly install nvidia-drivers, not just the legacy ones.

on another laptop i have also problem with hibernation. it is running on devuan beowulf

sudo hibernate
hibernate:Warning: Tuxonice binary signature file not found.
Some modules failed to unload: nvidia
hibernate: Aborting suspend due to errors in ModulesUnloadBlacklist (use --force to override).
