From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Or try using any form of desktop automation... which is a show-stopper and it doesn't look like Wayland plans to do anything about it any time soon.
I don't see how this is a Wayland problem. X11 has no desktop automation integrated either. You had to use third party tools for that like Autokey. And admittedly, there is still no comparable replacement for Wayland as far i know (maybe KDE scripts? https://develop.kde.org/docs/plasma/kwin/api/ or https://github.com/ReimuNotMoe/ydotool ?). But that is because nobody has fully build one yet, not because some inherent absence of necessary wayland functions.
It actually is because of Wayland design. In their quest for "security" they've made it impossible for automation and accesibility tools to do their job.
It's a glaring omission in Wayland going forward, for zero gain. Most of the touted Wayland security advantages are hogwash.
I mean if it’s goal was to prevent scripts from using the graphics env maliciously then it seems to have made some progress if you can’t even automate it with good intentions
We need to keep a balance between security and convenience, to avoid systems becoming too awkward to use. Wayland tipped this balance too far on the side of security. Malicious local exploitation of the graphics stack has never been a big issue; consider the fact that someone or something would need to compromise your own account locally, at which point they could do much worse things than moving your windows around. It's not that the security threat doesn't exist, it's that Wayland has approached it at the wrong end and killed a lot of useful functionality in the process.
Also consider that this issue has existed for the entire history of desktop graphics on *nix and nobody has ever deemed it worth to destroy automation for it. If it were such a grave security hole surely someone would have raised the alarm and fixed it during all this time.
My opinion is that Wayland has been using this as a red herring, to bolster its value proposition.
Technically i think the worst they could do would be to record your screen. (Barring some extra fancy exploits or something.)
People often think that things like recording your screen or keylogging are the worst but they're not. These attacks would require you to be targeted by someone looking for something specific.
Meanwhile automated attacks can copy all your files, or encrypt them (ransomware), search for sensitive information, or use your hardware for bad things (crypto mining, spam, DDoS, spreading the malware further), or most likely all of the above.
Automated attacks are much more dangerous and pervasive because they are conducted at massive scale. Bots scan massive amounts of IPs and try all the known exploits and vulnerabilities without getting tired, without caring how daunting it may be, without even caring if they're trying the right vulnerability against the right kind of OS or app. They just spray everything and see what sticks.
You're thousands of times more likely to be caught by such malware than it is to be targeted by someone with the skill and motive to record your screen or your keyboard.
Secondly, if someone like that targets you and has access to your user account, Wayland won't stop them. They can gain access to your root account, they can install elevated spyware, they can patch Wayland and so on.
What Wayland is doing is the equivalent of asking you to wear a motorcycle helmet 24/7, just in case you slip on some spilled juice, or a flower pot falls on your head, or the bus you're in crashes. All those things are possible and the helmet would come in handy but are they likely? We don't do it because it's not, and it would be a major inconvenience.
Yup, or even a simple
notify-send. Trying to work out which environment variables are needed to get the damn thing to focus on the window in question which may or may not be an X11 window within Wayland. The magic formula I've learned so far:(oh and sometimes you might need to preface that all with a
sudo, oh and there's no guarantee that the Display is at:0, even if no other display is in use). Eaaazyyy peaaaazyyyI will say that
wtypeis the one wayland automation tool that does not need any preamble. It just works out of the box, genuinely good engineering by the developers on that project.
