Because people here accuse Poettering of being an asshole: I've read some of his blogposts and seen some talks of his and him doing Q&A: He answered professionally, did his best to answer truthfully, did acknowledge when he didn't know something. No rants, no opining on things he didn't know about, no taking questions in bad faith.
As far as I can tell all the people declaring him some kind of asshole are full of shit.
Ok that's weird. My first guess would be something kernel-related, so maybe try booting the old kernel if you still have it, or just try a different kernel.
Really long freezes, while it could be something else, are often caused by the RAM being full, this is called thrashing.
Big memory hogs like the browser or discord could trigger thrashing behaviour if you're already low on RAM. Since this happened after an update, the most likely cause is a bug in any one of the many processes that are running on your computer. That kind of bug is called a memory leak, where a process is requesting memory for something, but then fails to give it back when no longer needed.
You should monitor memory usage to see if it is that, and to find out what process it is.
Bill Gates is a monopoly capitalist with zero scruples. He screwed over so many people, vacuumed up so much wealth from all other sectors of the world economy. He has zero qualms about doing this either: There's video of his depositions in the anti-trust case against Microsoft, and the whole fucking time he just argues semantics in response to the questions, and when pressed after five minutes of defining every fucking word in a sentence, almost always claims he doesn't know or recall. Obviously a guy that thinks being as dishonest as it is possible to get away with is perfectly good business. And he does that despite whatever the outcome of the case, he'd be richer than billions of humans collectively. What pathology is this?
There's so much more shit, like the incessant lobbying for medical patents worldwide, or how, according to Melinda, Gates loved hanging out with Epstein.
Now, why would anyone want to have their picture taken with that guy? Torvalds is such an unprincipled lib.
Edit: Listened to some of the deposition in the background. Here Gates is being extremely annoying for example: The interviewer reads back an email from Gates saying something like "browser share is a very, very important goal for this company", and then asks what other companies he's comparing browser share with. Gates goes several minutes arguing he's not talking about any other companies, since literally there are no other companies mentioned in that very sentence, obviously pretending like he doesn't understand the question. If you listen to all the shit before, they have to go over whether "browser share" means "market share" (Gates says no), whether "very, very important" and "important" have different meanings (Gates says not necessarily, could be hyperbole), and that sort of stuff for minutes on end. Like seriously listen to this, I cannot even describe how stupid it is.
Yeah that stuff I myself got rid of back in the Gnome 1 days when you could still customize all that. I appreciate that the Gnome devs came to the same conclusions as me.
- Desktop icons are usually hidden behind windows. It makes more sense to put launch icons in front of everything else, like Gnome does when you hit the Win/Super key.
- Minimize is unnecessary when you have workspaces and efficient window switching methods. Same for the task bar.
- A long time ago, when I was young, I played around with themes and shit, when that was still supported. There were always problems. Theming any complex set of applications yourself is basically impossible without causing issues, and themes made by others also exhibited this problem. You need a concerted long-term effort, plus buy-in from basically all app development teams, to make a comprehensive theme. Note how Microsoft/Apple don't want to support theming either.
- Systray was always some excuse for apps to just keep running in the background while not taking up taskbar space. Steam can go fuck itself, just please exit when I ask you to, and don't treat the close button as "minimize". If I wanted Steam running in the background I would just put it on another workspace.
I have this working on Debian like how you have it set up, everything on an encrypted lvm volume, except for boot and efi. Just one disk though. When waking up, it asks for the password like it does during normal bootup. It then restores RAM from the encrypted swap after you type the password. I think it worked out of the box, but it has been a while, so not 100% sure if I had to enable this somehow. Anyway this looks good to me.
If you manually run systemctl hibernate, does that work? Assuming this also does not work, you need to look at the logs during the failed hibernate attempt. Probably something like sudo journalctl -f and/or sudo dmesg -wH (for kernel logs). Open this up in two terminals, run systemctl hibernate and observe any errors or warnings.
It's possible this is a hardware/driver issue, i.e. a driver prevents hibernation or fails at it. You may be able to figure out which driver/device is responsible by looking at the logs.
Interesting, thanks.
The tokens can be worth different amounts. There can be 1 ¢ tokens, 10 ¢ tokens, 1 € euro tokens, 10 € tokens, whatever. Your wallet app will, when withdrawing, generate various tokens worth different amounts.
Using those tokens will be somewhat like paying in cash at a store that does not return any change. You gotta pay the exact amount. In order to facilitate that, you'd withdraw tokens worth only small amounts. There wouldn't be like be any 50 € tokens in practice. If you wanted to withdraw 50 €, you'd get 1000 1 ¢ tokens, 100 10 ¢ tokens, and the rest 1 € tokens or something like that, to make sure you always have the exact amount ready to pay for anything.
I looked at this a looong time ago, but the basic idea is that the tokens (equivalent to cash coins/banknotes) are generated on the end user's device, through some public-key cryptographic back-and-forth protocol. The issuer (bank/central bank/payment provider) does not see these tokens (they're only on the end users device), but can verify that they're legit (i.e. issued by them) somehow.
You can take one of these tokens to them, and deposit it in an account. They won't know who it's from but they know it was legitimately issued by them. Depositing a token is also supposed to be the only way of figuring out if it is a legit token, the bank will not tell you if a token is legit unless you deposit it.
When someone pays with these tokens in a shop, the shop will want to immediately (during checkout) deposit them, to make sure they're legit, and also to make sure the token hasn't been double spent. A shop that doesn't do that makes itself vulnerable to fraud. This means shops will have a hard time hiding their revenue (to dodge taxes) compared to cash.
If someone you trust gives you a token (birthday money from your grandma, say), you don't have to immediately deposit said token, since presumably you trust your grandma to not give you fake or double-spent tokens. Since you trust you grandma, there is no need to deposit the token and involve the bank, and that transfer would be untraceable (it's literally just copying a number from her phone to yours).
The idea is that shop owners would have a hard time dodging taxes without opening themselves up to fraudsters using fake tokens, while the customer cannot be identified. You'd also be able to exchange tokens with family and friends in a way that isn't traceable, as long as you trust them to not screw you over.
Ok so it's not the uinput permissions.
When you use lightdm, do you use it to log into a Gnome wayland session, same as with GDM? Or is there any other difference between using GDM and LightDM? What exactly is/isn't working, and how can you tell it is related to the XTEST extension?
Also I can use the PS5 controller as a mouse just fine.
Ok, this could maybe be the kernel driver creating a "real" touchpad device. Steam is able to create fake/virtual mouse and keyboard devices, I suspect that's what steam uses XTEST and/or uinput for. So even though your PS5 touchpad works, that does not invalidate my theory that steam wants XTEST for mouse/keyboard input fakery, because that's what exactly what XTEST is for.
So technically, Steam wouldn't require XTEST for controller input, it would require XTEST to map controller inputs to fake mouse or keyboard inputs. I don't know what exactly steam does if XTEST isn't present, like what exactly doesn't work?
And XTEST is an X11 protocol extension, it probably doesn't work properly under Wayland anyway.
The null here is concerning to me.
Dunno, '(null)' might just refer to the default connection (or server or screen or whatever X11 object this refers to), so not sure if this something to be concerned about. I presume X11 clients in general do work? Like xterm or xeyes work, right?
I am having the same bug as in here :/
The fact that you cannot log in may seem/look like that exact issue you linked to, but that's from 2019 and may have a different cause. In general, GDM will start some executable, (i.e. gnome-session or something like that, or at least it used to be gnome-session, haven't used gnome in a while) which if it exits/crashes this will kick you back to GDM. It could crash for many reasons.
You should check the logs for sure for both issues. X11 session logs (relating to Gnome X11 not starting), should be in ~/.xsession-errors (or ~/.xsession-errors.old for the previous session, I think). There may be a /var/log/Xorg.0.log for xorg, which I guess could also be the thing crashing (maybe). There may be other things logged with journald that could be relevant. journalctl --user should show all the logs for the user session. Logs from Gnome, since it runs as your user, would presumably show up there. My guess is all the relevant logs for a Gnome wayland session would also be there, as well as (hopefully) Xwayland errors/warnings, since Xwayland is actually the thing that would report it doesn't support XTEST.
Note that journalctl likes to show the oldest logs first, so look at the timestamps. You can press G to scroll to the end. There are various ways to filter messages, look at journalctl --help. You might want to use --grep to look for anything related to XTEST or xwayland.
Lightdm and GDM are systemd units (systemctl list-units), the logs would show with something like sudo journalctl -u lightdm.

On Linux/Unix (not sure about other platforms), you can configure a "Compose key" (people usually use something like the Menu key, or the right Alt key).
You can then hit that Compose key, followed by multiple other keys and they will be combined into a character, usually roughly relating to the shapes.
etc. There's a big table somewhere where all these are defined.
On android keyboards you can hold down the letter and get a list of "alternative" letters (seems to depend on the keyboard and keyboard layout configured what you get), you can also configure multiple languages/keyboards and then switch between them, by holding the spacebar.
