Enabling Glamor/DRI3 Fedora 29

Hello, I am pretty new to Linux and i have literally tried every major distro out there and all seemed to have tearing/bad performance except Fedora 29 after updating it. Everything is working exceptionally smoother and i can see immediate increase in FPS. However

  • How do i know which graphics driver is used and how could i configure it.

Running inxi -G yields:

Graphics: Device-1: Intel Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics driver: i915 v: kernel Display: x11 server: Fedora Project X.org 1.20.3 driver: i915 resolution: 1920x1080~60Hz OpenGL: renderer: Mesa DRI Intel Haswell Desktop v: 4.5 Mesa 18.2.6

Which seems to indicate that i915 driver is used. But if i try to create a config file to enable DRI3/Glamor at /etc/X11/xorg.conf.d/20-intel.conf and set the driver to i915 GDM fails to login (returns to login screen). if driver is set to modesetting or intel it doesn't have effect but i guess that's due to neither modesetting nor intel driver is used.

  • In inxi output there;s no OpenGL specified so i guess there's something wrong with OpenGL, How could i further diagnose this issue?
