Bug ID: 387469
Summary: Compositing does not work with Nouveau
Product: kwin
Version: unspecified
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: nuor...@gmail.com
Target Milestone: ---
On a laptop with both integrated Intel and an Nvidia card, Kwin cannot enable
OpenGL compositing on the Nouveau driver. OpenGL compositing also works when
using the integrated Intel. OpenGL compositing also used to work with the
Nvidia drivers, but broke sometime this year.
