I second this, I use it with a Dell docking station at work (90% sure it's the same model) and updates for firmware just work on Kubuntu.

It's the moderation staff's responsibility. Sorry for nitpicking, I understand in this case it's likely the same people.

I just get triggered when I hear that an open source software developer should have any responsibilities at all (maybe apart from some extreme examples), and I wouldn't like this idea to stick in anyone's head.

From what I understand, the RISC-V ecosystem is not polished enough yet, so the state of PineTab-V roughly represents the state of the entire platform for desktop Linux.

My personal workaround is a smartphone book case with a spot for the debit card.

The entire idea of Ubuntu Touch device support, was to be based on Halium. It's a bit different than regular mobile Linux (outside of Droidian, of course), where mainline is a requirement.

It won't be much of help, but I have a few devices:

• Xperia X which so far works well, except that it feels like the phone's internals are a bit too slow for today's standards, so even if I will use it for the time being, if I were yo,u I would pick something more powerful.
• OnePlus 6 which would be very cool (especially that it's one of the best phones for regular 'mobile Linux' so far), if not for shutdown being bugged, which results in time getting reset on every boot. But it's fast enough, and I hope the bug will eventually get a fix.
• last time I tried PPP was not good enough, but it's been ~2 months ago and support was quite fresh. Might need to check again.

I looked through the posts.
Explanation of the issue: the userspace implementation of OpenGL for Xorg, called GLX,does not work, maybe it isn't loaded. From what I see, /usr/lib/nvidia/xorg/libglx.so is no longer included in nvidia-utils package, the new name for it is probably libglxserver_nvidia.so

Did you have any lines with (EE) in Xorg.0.log?
Do you see if this log says, if libglxserver_nvidia.so was loaded correctly?
Wouldn't hurt to check, if nvidia kernel module is loaded: lsmod | grep nvidia
Maybe reinstallation of nvidia-utils package could help, although I am pretty sure this was done already when you removed and added nVidia driver again.

Feel free to PM me, whenever you give it another go, even if it's half a year from now :) I'll do my best to provide you some advice.
('nv' is an old driver for old nVidia cards, you shouldn't look in that direction, it's normal that it doesn't load, if nvidia driver does)

Looks like they have valid reasons for doing this - also, remember: they still allow selfhosting. It's less about what they want to do, and more about 'people are shit, as usual, and this is why we can't have nice things'.

• KeepassXC should just work, if the browser's key was added to your KDBX database successfully. Other than that, I am surprised.
• Yup, the motherboard clock thingy is a consequence of Windows storing local time, vs Linux storing UTC. It's a minor thing to fix in any of these systems, though.
• Shortcuts thingy - never had a problem, although I did have a problem with KDE's keyboard shortcuts to run a program, which may be related workflow and maybe both were/are broken.
• KDE Connect is surprising, as at least for me it worked flawlessly
• The reboot thingy must be related to Linux Mint. I saw similar thing in EndeavourOS. One nice thing that some distributions implemented, is the ability to apply updates when you poweroff - from my point of view it's a less annoying solution than what you describe.
• I can't comment on the 'cherry on top' one without more details.
  I had a somewhat similar issue on my work laptop a short while ago, when I installed a program, which included a bugged XML settings file, then ran system update. When the updater tried to rebuild some caches (related to ie. icons, MIME etc.), some programs which use these caches simply stopped working. Reinstalling all packages with apt was the only thing that helped, to this day I do not even know all of the parts of my system that were broken.
  But this was one of these issues that happen once per 5 years, and leave you scratching your head and asking "what the hell is going on here?". The difference from Windows is that in Linux, you can have a high understanding of system's internal modular components (at the cost of time needed to learn it), and regular system issues can be identified after a few minutes of Googling.

I'm as skeptical as you are, but at least they automatically preinstall a few useful gaming apps by default, ie. LatencyFlex.

Mobile Linux distributions for smartphones might offer some hints on how to tackle your problems - these apps are created in a convergent way, which makes them work well on laptops, tablets and PCs alike. Look for an alternate file manager, for example, to replace Nautilus. Check out https://linuxphoneapps.org/apps/

Maybe it's obvious, but how about Kodi?
It has support for CEC (for utilizing your TV's remote through HDMI), of course there are other input options as well.
There's plenty of plugins to support online video services. Needs some work to configure them, and sometimes it requires maintenance when a plugin stops working, but I was in general happy with the way it worked while I used it for a few years.
