I've read some questions, like #1297875, but finally not found how to replace graphics driver i915 with the iris driver on Ubuntu 20.10 running on a i7-1165G7 that bring a Intel Iris Xe Grahpics PCI id [8086:9a49].
- Should I use https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers ?
- some changes in X11 config ?
- Or perhaps I misunderstand... kernel use i915 and iris driver is only for user-space OpenGL with MESA ... As I read at https://linuxreviews.org/Intel_Iris
Any idea please ? Thanks.
UPDATE after installed oibaf drivers
I miss understand something ... As we can see below, the i915 driver is used but for OpenGL it is a "Mesa Intel Xe Graphics (TGL GT2)"...

After reading this page at intel.com Intel® Iris® Xe MAX Graphics with Linux it seems "normal" that driver "i915" is used for Xe Graphics as they say:
While support for the Intel Iris Xe Graphics processor has already been integrated into Linux* and integrated into Linux-based distributions such as Ubuntu 20.04.1, enabling work for the Intel Iris Xe MAX graphics processor in Linux* is ongoing.
