Perhaps you are right, the pause was about 10 minutes.
During the first boot after the procedure with the battery, the computer beeped something about a checksum mismatch.
Maybe I’ll get around to repeating it, it takes relatively few screws to turn, a lot.

@Mike

Maybe you should have just used the old profile instead of the new one?

about:profiles

and look at what profiles are there.

Regards.

@GlennW

I'll try.
Although, in my case the problems are due to a specific BIOS.
During the OpenSuse installation, the /boot/efi partition was explicitly specified, so it booted. The rest of the distributions that I tried selected MBR, but when I tried to select efi they reported an error

grub-install: warning: Cannot set EFI variable Boot0007.

It's already mounted, there are 50 files in this folder.

root@devuan:/# mount -t efivarfs none /sys/firmware/efi/efivars
mount: /sys/firmware/efi/efivars: none already mounted on /sys/firmware/efi/efivars.
       dmesg(1) may have more information after failed mount system call.
root@devuan:/# 

@stargate-sg1-cheyenne-m...
Maybe something has changed since 2012.

In fact, as I understand it, it’s a crooked BIOS and that’s what causes all the problems.
On another laptop, everything is installed correctly, regardless of the number of OS, including Win.

@fsmithred
I used devuan_daedalus_5.0.0_amd64_desktop-live.iso, everything is default.
Devuan is installed and updated.
/sys/firmware/efi exists, that's the reason

root@devuan:/# grub-install
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
root@devuan:/#

In fact, there is such a section and in it there is an opensuse boot record through which the devuan is loaded.
The size of this partition is 1.8GB.

@rolfie
No, this is an old computer, Devuan is already installed on it, with
there are no problems with this.

P.S. It’s even more interesting here, another Linux is installed - PSlinuxOs. The one by default, without asking where the bootloader was installed, it works, but it’s not in the EFI section. It looks like it's written into the MBR and my computer can load any version.

Yeah, and Google also killed cameras by releasing its Google Pixel.

@alexkemp
The main thing is that everything works for you and you are ready for the hearings.
The rest is little things...

Good health alexkemp !
I don't know when v4l was included in the kernel. My desktop has an ancient (10 years old) usb webcam, still 640x480. Even in those days, she worked without problems and I observed my face in some KDE3 program.

Regards.

Maybe I don't understand something.
The v4l subdeck is included in the Linux kernel. Usually webcams use its driver and there are no problems, at least I didn’t have any problems with them.
In addition to the site gov.uk, there are many others that allow you to check the camera, for example
https://webcamtests.com/
Or just turn on the video from the webcam in the media player, without any Internet connection

P.S. Lastly, I don't think it's a good idea to use the site gov.uk unnecessarily. Government services have enough to worry about without DDoS attacks.

Quite seriously - this is wonderful!
Freedom of choice is what makes Linux so attractive.

Good health to everyone!
I'm doing great, we are more writers than readers.

Therefore, I will repeat what I wrote in my post above

From this point of view, I would be interested to see comparisons of the loading speed of different alternative init systems.
Win is of little interest to me; on a computer with i7, SSD and Win8 the difference is even more noticeable (but you need either a stopwatch or something similar to measure fractions of a second).
This is easier to measure on an older computer.

But from a purely practical point of view, ten seconds of loading is not a problem for me; I’m more concerned about the number of running system processes.

@Aliz24
The point here is rather not in a specific DE, Synaptic is a GUI for the command line, allows you to edit repositories and is tested by developers. If I may, Synaptic is the main course, and the beautiful programs in DE are the dessert.
