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).

i had used fglrx driver before and also use the proprietary driver on ubuntu as i found it more responsive than the opensource,
also some features enable to use AMD VCE encoding in Handbrake (which is similare to quicksync and nvidia enc)
which opensource don't yet enable.
