If wlan0 is listed in /etc/network/interfaces then connman will ignore it. Use either ifupdown or connman, not both.

EDIT: if you're running chimaera then I would recommend iwd instead:

# apt install iwd orphan-sysvinit-scripts wpa_supplicant- connman- dhclient-
# cp /usr/share/orphan-sysvinit-scripts/iwd /etc/init.d/
# update-rc.d iwd defaults

Then use iwctl to configure your wireless connection and add this to /etc/iwd/main.conf:

[General]
EnableNetworkConfiguration=true

And add a network configuration stanza to /var/lib/iwd/<name of SSID>.psk, for example:

[IPv4]
Address=192.168.0.23
Netmask=255.255.255.0
Gateway=192.168.0.1

The wlan0 lines can be removed from /etc/network/interfaces once iwd is configured.

Can you share the full error?

4GiB is certainly enough for Firefox, even for my Arch box with 32GiB of RAM available:

737.1 MiB +   1.0 GiB =   1.7 GiB	firefox (15)

I think you'll have to tell the Pale Moon developers about their broken POS software

You can generate a stack trace for them by following https://wiki.debian.org/HowToGetABacktrace but I don't know about the relevant debug symbols. Ask on their forums.

So the problem must have been caused by a different missing dependency for the desktop task. Reinstalling the entire task would have pulled it back in and been quicker and more convenient than reinstalling. Remember the trick next time this happens, as it probably will because you didn't get to the root cause and instead papered over the problem by reinstalling.

Maybe I'm just plain wrong about the www-browser dependency then but I do seem to remember this cropping up before. Perhaps it only happens if the full desktop environment is installed with tasksel (which is used in the netinstall ISO).

Lots. Debian has *many* obscure abstractions which complicate the experience massively compared to (for example) Arch.

I agree but I think it should be part d...

SLiM is ancient, unmaintained and it doesn't support login sessions correctly. It probably has several other bugs as well thanks to 8 years of code rot.

Do you still experience the delay with (for example) GDM? How about a plain console login?

Have you tried <Mod4>+<shift>+<return>? Mod4 is also known as the "Windows" key.

And is a terminal emulator installed?

update-alternatives --display x-terminal-emulator

Otherwise check ~/.xsession-errors for any clues.

That's not a solution, it's a (poor) workaround. A number of possible solutions are listed in my provided link which you clearly couldn't be bothered reading.

For the benefit of anybody else who encounters this problem the actual solution would be to reinstall the desktop task so if you're using Xfce the command would be

# apt reinstall task-xfce-desktop

I don't think so. If you're setting the time ahead by more than the timeout value for the screensaver then activation would be expected.

Why are you attempting to set the time manually? Can you not just install the ntp package and rely on the interweb instead?

Your desktop task has a dependency on the www-browser virtual package, which is provided by firefox-esr but not Brave. Installing something like w3m or elinks will supply the dependency.

See https://github.com/edio/intelpwm-udev for a script, configuration file and udev rule to set the PWM frequency automatically.

You could report the issue to the Vivaldi developers, perhaps they can do something about it.

The real problem here is that Google are now driving website development through their browser dominance. Classic EEE behaviour. That's why I use Firefox even though Mozilla make *terrible* management decisions — it's the only real alternative to a standards monopoly.

I don't use uBlock so I'm sure golinux is correct.

Note that the big G doesn't need the browser to track you because their ubiquitous Analytics tools already do that. Be sure to install the Analytics blocker extension that Google try to hide as best they can:
