A lighter-weight kscreenlocker alternative (kscreenlocker uses a lot of VRAM) (lemmy.ca)

According to nvtop, on both my nvidia and AMD computers, kscreenlocker_greet uses 200-400MB of VRAM while the screen is locked -- doesn't that feel excessive for a simple screen locker (I do realize that it's QML and thus in theory can use as much VRAM as say plasmashell).

This is kind of annoying as I was trying to set up a chatbot using my main desktop while it's idle, and would like that extra 400MB back for a higher context length.

Wasn't sure if this was a bug or just how software is nowadays so I opted to start a discussion rather than finishing filing a bug at bugs.kde.org.

Anyway, anyone know of an alternative screenlocker for kwin_wayland?

I thought I would disable kscreenlocker completely (by setting the screen to never lock?) and use something like swayidle and swaylock, but it doesn't look like kwin supports the wayland extensions required to use swaylock.

I'd be surprised if there was any alternative, to be honest.

I'd file the bug - your case is not common. I run kscreenlocker just fine and it's not such a ram hog here.

VRAM or regular RAM? It doesn't use that much regular RAM.
