Bug ID: 507997
Summary: Warn user that VirGL is not enabled when running
inside a VM
Classification: Plasma
Product: kwin
Version First 6.4.3
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: performance
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Current versions of virt-manager (5.0) and gnome-boxes (48) don't enable
hardware OpenGL acceleration through VirGL by default. Other software like
VirtualBox might not even support VirGL.
If Plasma detects that it's running inside a VM and VirGL is not enabled, it
should display a warning about reduced performance and recommend to the user to
run a KVM+QEMU+VirGL based VM software.
While this might not solve the performance problem for users coming from
Windows (but at least they know the cause), it could improve the impression of
Plasma by users coming from other Linux desktops environment who want to try it
safely in a VM first.
