Description Neal Gompa 2021-07-27 01:05:36 UTC 
+++ This bug was initially created as a clone of Bug #1986222 +++

Description of problem:
Linux 5.14 introduces the new SimpleDRM driver as a generic fallback driver that supports KMS. GNOME Wayland does not support non-KMS graphics for rendering, and KDE Plasma's non-KMS (fbdev) rendering mode pretty much does not work. This driver makes it possible for desktop environments to *always* expect KMS to work, even if a native driver isn't available, which makes it simpler to support Wayland.

Please enable SimpleDRM so that it becomes achievable to use Wayland for "basic graphics mode" fallback configurations.

Version-Release number of selected component (if applicable):
5.14.0-0.rc3.29.el9

Additional info:
The lack of this driver led to bug 1952431 happening during Fedora Linux 34's development and I would really like SimpleDRM to be enabled so I can make more progress on solidifying Wayland support and remove hacks to disable Wayland in "basic graphics mode".

After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.

Re-opening since this is just our stale bot being too eager

Again, please don't mind our overeager stale bot at times.
