For remote desktop, I turn off the effects in plasma. They are turned off throughout the system, but only the screen blocker continues to work with effects. This makes some operations very difficult.
What becomes difficult with effects active? How are you turning effects off? Can you verify whether you're indeed talking about the screen locker, or is it the login screen?
For example, take remote work via krfb-krdc over a slow connection. In this case, a reduced palette of colors is used. If the effects are turned on, I see a lot of color spots running around the screen, not adding beauty, only taking up the channel and time. For the desktop, I can turn off the effects and everything works fast. But it doesn't work for the blocker. I observed a similar picture on atomic netbooks, the plasma speed there is quite enough to work, but the effects have to be turned off. Unfortunately, this is impossible for a blocker. Another braking element is logging in via sddm, but I solve this problem by switching to lightdm. Otherwise, KDE plasma with disabled effects is comparable in speed and resource consumption to LXQT. This allows it to be used on weak machines, in the remote use option, for the graphical interface of servers in a virtual environment. Disabling effects gives a lot of options for using KDE Plasma, I would like this shutdown to apply to all elements of the system.
Thanks for the explanation. How exactly are you disabling effects that isn't working on the screen locker?
System settings-compositor Compositior: enable on startup This setting enable-disables effects for the entire system, except for the screenblock
Thanks. And what specifically would you expect to be disabled on the lock screen when compositing is disabled? Do you see *any* effect, or does literally nothing change on the lock screen when compositing is disabled for you?
You need to disable the smooth change of background brightness before the password entry line appears when you press any key on the locked screen.
All right cool, then this all makes sense, since none of the effects on the lock screen are provided by compositing! :) In general you'll run into a lot of visual effects and animations that don't change when you disable compositing in KWin because they aren't provided by the compositing system, so turning it off isn't guaranteed to be a fix for performance issues. In addition, on Wayland it's not possible to disable compositing. So in general, I would recommend that you submit bug reports for the actual performance issues you're facing, rather than submitting bug reports about workarounds for those performance issues not working.
Oh! I see now. In my localized version of KDE, "compositing" is translated as "effects". I think this is a more correct name, the user is not required to know the algorithms of effects, but should be able to disable them in those scenarios where they are not needed.
Ah yeah, that's not the greatest translation of the word "Compositing". Frankly it's not a great word in English either, but at least it's not something actively misleading like "Effects". This is probably worth a bug report for the Russian translation team. Can you submit one at https://bugs.kde.org/enter_bug.cgi?classification=Translations&component=ru?
