[Solved]enable Dri3 intel-nouveau

I wanted to ask if you can enable Dri3 on intel and nouveau,and what file should i modify,since xorg.conf.d is in /usr/share.
Or this is not possible on bl.

Re: [Solved]enable Dri3 intel-nouveau

Is it capable?

LIBGL_DEBUG=verbose glxinfo | grep libgl

Interesting info here: https://bbs.archlinux.org/viewtopic.php?id=211792

Re: [Solved]enable Dri3 intel-nouveau

Thanks, but if you do the command:

ettore@ectorpc:~$ LIBGL_DEBUG=verbose glxinfo | grep libgl
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 8086:0166, driver i965
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/i965_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/i965_dri.so
libGL: Can't open configuration file /home/ettore/.drirc: No such file or directory.
libGL: Can't open configuration file /home/ettore/.drirc: No such file or directory.
libGL: Can't open configuration file /home/ettore/.drirc: No such file or directory.
libGL: Can't open configuration file /home/ettore/.drirc: No such file or directory.
ettore@ectorpc:~$ 

In arch linux is enabled, I do not understand why it does not work here!
The file 20-intel.conf,can i put it in /usr/share/X11/xorg.conf.d/?
Or should I create the directory in /etc/X11?
regards

Re: [Solved]enable Dri3 intel-nouveau

I could not tell you, possible reason that BL is based on debian jessie stable and these kinds of upgrades may only available in testing. Arch is bleeding edge so...

What is the pros and cons of having Dri3 enabled?

As poronix you have better performances in rendering and more

I added the file 20-intel.conf, now the command from these answers:

ettore@ectorpc:~$ LIBGL_DEBUG=verbose glxinfo | grep libgl
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 8086:0166, driver i965

libGL: Can't open configuration file /home/ettore/.drirc: No such file or directory.

ettore@ectorpc:~$ cat /var/log/Xorg.0.log | grep DRI

Re: [Solved]enable Dri3 intel-nouveau

To take advantage of DRI3, install Debian testing/unstable and use the modesetting DDX driver.
