From 1d3323de5fe5656844ea57a16eb432f09a366140 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 8 Mar 2012 11:19:19 +0100 Subject: [PATCH] implement vnc_dpy_setdata The comment is wrong, we have to do something in the setdata callback.

Trigger #2: std vga + http://patchwork.ozlabs.org/patch/145479/ Signed-off-by: Gerd Hoffmann Signed-off-by: Anthony Liguori --- ui/vnc.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/ui/vnc.c b/ui/vnc.c index 8ee39bc..bdec33a 100644 --- a/ui/vnc.c +++ b/ui/vnc.c @@ -1936,7 +1936,10 @@ static void pixel_format_message (VncState *vs) { static void vnc_dpy_setdata(DisplayState *ds) { - /* We don't have to do anything */ + VncDisplay *vd = ds->opaque; + + *(vd->guest.ds) = *(ds->surface); + vnc_dpy_update(ds, 0, 0, ds_get_width(ds), ds_get_height(ds)); } static void vnc_colordepth(VncState *vs) -- 2.7.4
