Subject: [PATCH] utils: add new gdm-disable-wayland binary
|
|
|
675525 |
|
|
|
675525 |
We currently disable wayland for cirrus by calling printf
|
|
|
675525 |
from a udev rule. This works, but it's a little too open
|
|
|
675525 |
coded to easily write SELinux policy for.
|
|
|
675525 |
|
|
|
675525 |
This commit introduces a new program, gdm-disable-wayland,
|
|
|
675525 |
that does the same thing, but in a dedicated binary.
|
|
|
675525 |
|
|
|
675525 |
A future commit will change the udev rule to use the binary.
