From 443a38bd3f62864677779e983d7f565d41054d25 Mon Sep 17 00:00:00 2001 From: emersion Date: Sun, 28 Oct 2018 23:43:21 +0100 Subject: backend/drm: add WLR_DRM_NO_ATOMIC_GAMMA env variable This allows the legacy interface to be used instead of atomic if needed. This is a workaround to make some Intel GPUs work (if this variable is unset) as well as to make some AMD GPUs work (if this variable is set). --- docs/env_vars.md | 2 ++ 1 file changed, 2 insertions(+) (limited to 'docs') diff --git a/docs/env_vars.md b/docs/env_vars.md index 1b1a5fd6..b67d1652 100644 --- a/docs/env_vars.md +++ b/docs/env_vars.md @@ -7,6 +7,8 @@ wlroots specific considered the primary DRM device. * *WLR_DRM_NO_ATOMIC*: set to 1 to use legacy DRM interface instead of atomic mode setting +* *WLR_DRM_NO_ATOMIC_GAMMA*: set to 1 to use legacy DRM interface for gamma + control instead of the atomic interface * *WLR_LIBINPUT_NO_DEVICES*: set to 1 to not fail without any input devices * *WLR_BACKENDS*: comma-separated list of backends to use (available backends: wayland, x11, headless) -- cgit v1.2.3
