If the Wayland compositor sets a rotation on the output, Xwayland translates the transformation as an xrandr rotation for the given output.
However, if the rotation is not supported by the CRTC, this is not a valid setup and xrandr queries will fail. Pretend we support all rotations and reflections so that the configuration remains a valid xrandr setup. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=99663 Signed-off-by: Olivier Fourdan <[email protected]> --- v2: We don't need to support all rotatons and reflections, just one (RR_Rotate_0) and use it in the current config for rrGetInfo() v3: Split the patch in two as there two issues. One being the config set by Xwayland when there is a transformation not supported by the CRTC, this is this patch. hw/xwayland/xwayland-output.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/hw/xwayland/xwayland-output.c b/hw/xwayland/xwayland-output.c index f3ce763..bdf270a 100644 --- a/hw/xwayland/xwayland-output.c +++ b/hw/xwayland/xwayland-output.c @@ -31,6 +31,12 @@ #include <randrstr.h> #define DEFAULT_DPI 96 +#define ALL_ROTATIONS (RR_Rotate_0 | \ + RR_Rotate_90 | \ + RR_Rotate_180 | \ + RR_Rotate_270 | \ + RR_Reflect_X | \ + RR_Reflect_Y) static Rotation wl_transform_to_xrandr(enum wl_output_transform transform) @@ -266,6 +272,7 @@ xwl_output_create(struct xwl_screen *xwl_screen, uint32_t id) ErrorF("Failed creating RandR CRTC\n"); goto err; } + RRCrtcSetRotations (xwl_output->randr_crtc, ALL_ROTATIONS); xwl_output->randr_output = RROutputCreate(xwl_screen->screen, name, strlen(name), xwl_output); @@ -317,7 +324,7 @@ xwl_output_remove(struct xwl_output *xwl_output) static Bool xwl_randr_get_info(ScreenPtr pScreen, Rotation * rotations) { - *rotations = 0; + *rotations = ALL_ROTATIONS; return TRUE; } -- 2.9.3 _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
