Description N. W. 2016-11-27 17:30:31 UTC
Hi,

does anyone know how to enable DRI3 for xf86-video-modesetting?

Regards
Comment 1 Timo Aaltonen 2016-11-27 22:04:33 UTC
it's on by default

> it's on by default

But Xorg.0.log only mentions DRI2, see:

user@machine:/var/log$ grep DRI Xorg.0.log
[    13.309] (II) glamor: EGL version 1.4 (DRI2):
[    13.952] (II) modeset(0): [DRI2] Setup complete
[    13.952] (II) modeset(0): [DRI2]   DRI driver: i965
[    13.952] (II) modeset(0): [DRI2]   VDPAU driver: i965
[    13.976] (II) GLX: Initialized DRI2 GL provider for screen 0

Why doesn't it say anything about DRI3? When enabling DRI3 in xf86-video-intel for example, Xorg.0.log lists DRI3, but with xf86-video-modesetting it does not (see above).
Comment 3 Mike Russo 2017-01-11 19:42:10 UTC
Try running this command from a bash prompt:

LIBGL_DEBUG=verbose glxinfo | grep -i libgl 

Whether I use modesetting or intel with DRI3 enabled, I get:

libGL: Using DRI3 for screen 0

(BTW I was just as confused as you about why I didn't see DRI3 in the Xorg log before I found someone who quoted this command. I think that the modesetting driver just isn't programmed to print it out properly.)

While a cosmetic issue, it is very confusing indeed. Please keep this bug open. It needs fixing.
