If you copy the fimware manually, a manual update-initramfs -u -k all is mandatory.

rolfie

Ahh you mean the bios.

First of all you should load the latest fimware-linux-nonfree from backports. I guess that is missing, your amd-graphics firmware package is outdated for this new HW.

What do you mean by:

What package is that?

When I summarize the feedback received on lsusb and lsblk, the camera is found on the usb subsystem, but the product id seems to be unknown. Contrary to my Panasonic which is working fine there is no sign of any memory. Looks like its not recognised at all. Strange for a product that is more that 6 years on the market. On the other hand I am not familiar with Sony products, I avoid them whereever I can.

@OP: when I read what you wrote in your first posts it is very interpretable if the camera worked under ASCII. I would assume when it worked under ASCII it also should under Beowulf. Buuuuut: we have the proof that there is no memory recognised. Very strange.

So  please give Magnus' suggestion a try. Maybe a dedicated udev rule fixes the issue (have you optimised something?).

Isn't that camera an USB device? I would suggest first of all to check on the console if and how the camera re. its memory stick? shows up when plugged in. lsusb

Have you tried all available USB ports on the laptop?

rolfie

Give firmware-amd-graphics and the 5.7 kernel from backports a try.

Cinnamon and old style frames etc:

You might also consider installing cinnamon-themes and mate-themes.

What the resizing etc is concerned, I think its related to a change in FF 78ESR.

Because I was looking for a way to scale LightDM only.

Some further mining in the net brought me to these pages:

Well, the xft-dpi tweak just has the effect that the fonts on the greeter screen are scaled with the dpi setting. Nice, but not what I wanted to see. The login window keeps its size, everything looks very squeezed in with 144dpi.

Looked at the available modes on the system.

Setting LightDM to 1920x1080 would be nice. The mode is already available, so I don't need to add this.

But: Looks like both the selivan and the evren-yurtesen blogs aim at Ubuntu. When looking at the file system I found that the directory structure and at least some of the file contents of lightdm.conf is different under Beowulf as described.

In the moment, I am lost. Maybe I need to go down the route to use a xorg.conf for a general scaling of the graphics mode. Needs to settle a bit.

Well, I also found a rant in the German Debian forum where somebody tried to scale a 4k monitor and gave up. Was about xfce.

Thank you for your input. rolfie

When I condense that correctly, a new /etc/xprofile should do the job. I added a simple line with xrandr --dpi 140, also tried 70 instead of 140, added the full path, with no effect.

BTW, here is the output from 3 of my PCs with various monitors. First iof all my X470 workstation with a 27" monitor, no tweaks.

:~# xdpyinfo | grep -B2 resolution
screen #0:
  dimensions:    2560x1440 pixels (677x381 millimeters)
  resolution:    96x96 dots per inch
:~# xrdb -query | grep dpi
Xft.dpi:	96.0234375

X570 with ordinary 24" monitor, no tweaks.

:~# xdpyinfo | grep -B2 resolution
screen #0:
  dimensions:    1920x1200 pixels (508x317 millimeters)
  resolution:    96x96 dots per inch
:~# xrdb -query | grep dpi
Xft.dpi:	96

And finally the object of interest, first with settings tweaked to 140 dpi with MateTweak, then reset to default.

:~# xdpyinfo | grep -B2 resolution
screen #0:
  dimensions:    3840x2160 pixels (1016x571 millimeters)
  resolution:    96x96 dots per inch
:~# xrdb -query | grep dpi
Xft.dpi:	70

:~# xdpyinfo | grep -B2 resolution

What have I overlooked/misunderstood?

rolfie

I must admit that I am not happy with that decision. It should be my responsibility how to deal with my posts. Gives me a strange feeling of being controlled/limited?

I still belong to the working class, I am not sitting on the computer all the time. I reserve the right for me to think about my threads for more than a day. I consider myself to be a sensible guy, under normal circumstances I wouldn't try to delete my complete history or pul away useful information from others, but .... no I can't accept that approach.

Devuan was something about freedom, and if this forum is cutting of from my personal freedom I must consider to retract. I am sorry,

rolfie

Edith: added some of my thoughts about the dicussion.
