How to enable "Direct Rendering Display Compositor"?
-
My current system is:
Distribution: Archlinux Kernel Version : 6.3.1.zen2-1 Plasma Version : 5.27.5-2 KDE Version : 23.04.1-1 Frameworks Version : 5.105.0-1 Qt5 Version : 5.15.9+kde+r9-1 Wayland Version : 1.22.0-1 XOrg/Wayland Version : 23.1.1-1 Mesa Version : 23.0.3-1 LibVA Version : 2.18.0-1 VDPAU Version : 1.5-1
My browser is
vivaldi: 6.0.2979.18 (Stable channel) stable (64-bit)
I managed to enable most of the hw acceleration but there seems to be no way to enable "Direct Rendering Display Compositor" (aka dr-dc).
The flag should be the one labelled as "Enables Display Compositor to use a new gpu thread."
But, no way.I do know that all this doesn't mean hw acceleration is actually used.
Is this a limitation due to my architecture (64bit Linux)?
If not, how do I enable that missing feature? Is there any pre-requisite or dependency to be satisfied?Thanks.
