Hi,

correctly). Gen4 was released in 2006:
https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Gen4

From the Xorg logs attached to bug 1820815

[  7821.744] (--) PCI:*(0@0:2:0) 8086:a011:1043:83ac rev 2, ...

So that's a GMA3150, as found in Pineview chipsets circa 2010 according to the wikipedia page linked above.

"a011" is precisely the last entry found in https://src.fedoraproject.org/rpms/xorg-x11-server/blob/HEAD/f/06_use-intel-only-on-pre-gen4.diff which explains why Xorg picks "intel" as seen in the Xorg logs:

[  7821.917] (==) Matched intel as autoconfigured driver 0
[  7821.917] (==) Matched modesetting as autoconfigured driver 1
[  7821.917] (==) Matched fbdev as autoconfigured driver 2
[  7821.917] (==) Matched vesa as autoconfigured driver 3
 
  Additionally, Xorg is also non-default, we use Wayland since some
  time.

That's correct, on the Fedora Workstation using GNOME - But Wayland is a protocol, just like X11, it requires a display server which is gnome-shell, and Alexei mentioned in the bug he's using another spin instead, so no Wayland there.

So indeed, that bug would unlikely affect the default Fedora Workstation.

HTH,
Cheers
