<pre>I presume the difference is that sna disables the primary plane on the CRTCs
prior to VT switch (so that we do not leak information to the next client).
If you did
diff --git a/src/sna/sna_display.c b/src/sna/sna_display.c
index 53eb9ca..af44dbc 100644
--- a/src/sna/sna_display.c
+++ b/src/sna/sna_display.c
@@ -7347,6 +7347,7 @@ void sna_mode_reset(struct sna *sna)
xf86CrtcConfigPtr config = XF86_CRTC_CONFIG_PTR(sna->scrn);
int i;
+ return;
if (sna->flags & SNA_IS_HOSTED)
return;
then you will get the same behaviour in sna as uxa on VT switch.</pre>
