Threaded Input Finally Lands In The X.Org Server

[starshipeleven]

probably because security through obscurity is a bluff, like pretending a closed source program can be secure at all

Well, no. Ok for the closed source, but it's not always so clear-cut.

Why military stuff and people are usually painted camouflage instead of let's say BRIGHT PINK?
Because camouflage will make them harder to detect and thus reduce the times they actually get hit.

Security comes from layering different things, so that if one fails there are others still in the way. Any defence will fail eventually, but its job is to slow down and dull the attack so the responders can react.

In the case in point, yes, moving the port to an arbitrary high number is good enough to reduce dramatically (like by 2 orders of magnitude last time I tried a honeypot on port 22) the attempts to hammer it. Making a bot that instead of scanning only port 22 needs to scan up to port 50000 or whatever carries a major performance penalty, not many do.

Because ssh itself isn't invulnerable even if the algorithm itself is and the admin chose a good long uncrackable password (or even better just the key and turn off the password, only the one with the key can login at all). There was Heartbleed for example.

This trick would buy time to get the server secure again, unless someone was targeting *specifically* that server it's wildly unlikely to actually find the ssh port at all in a reasonable time if it has to scan a zillion ports in all servers around.

Then OK, sure, not having ssh open on the outside at all and connecting only through a VPN is better (no duh) but you can't always do that.

isnt this one of the reasons why peple always complain about csgo on linux?

Peple lol wut. But seriously, I can feel that there's more input lag with multicore rendering enabled, even though FPS doubles.

So I just tried xorg server git afa9ae306b3e78abba1bbd111d5bf70b8e9adaf7 with modesetting on intel and some gtk programs like thunderbird don't update the window content correctly anymore... Anyone else seeing this?

xf86-video-intel doesn't compile for it:

because of https://cgit.freedesktop.org/xorg/xs...666c32d68a9d99
Replacing it with input_lock(); and input_unlock(); seems to work though and thunderbird works properly again.

Edit: Played a bit csgo. The performance with radeonsi still doesn't even reach stable 60 fps. It feels a little bit easier, but that could be a placebo. Especially with the low fps.

Just to be clear, I’m not a professional ‘gamer’. I’m just an casual gamer who greatly values his low latency and fps over any silly skill acquired 13 years ago. This being said, I am open to any and all criticism.
‘In this moment, I am euphoric. Not because of any phony skill's blessing. But because, I am enlightened by my threaded input.’

So I'm pretty sure that xorg git causes random stutters in the input (with xf86-input-libinput). Every time it prints "SYN_DROPPED event from "Razer Razer DeathAdder 2013" - some input events have been lost." to Xorg.0.log. So I think it may be related to the threaded input.
Anyone else sees something like that with xorg git?
