Dear all,
When I use SW cursor on XServer 1.6.0, there is a segment fault when
display rotation (xrandr --output xxx --rotate left). But it's OK on
XServer 1.5.2.
I trace the codes and find the cause. The function xxx_crtc_commit will
call xf86_reload_cursors().
In xf86_reload_cursors(),
cursor_screen_priv = dixLookupPrivate(&screen->devPrivates,
xf86CursorScreenKey);
/* return if HW cursor is inactive, to avoid displaying two cursors */
if (!cursor_screen_priv->isUp)
return;
In fact, if use SW cursor, I find the cursor_screen_priv is NULL.
And X accesses the null pointer. That's why segment fault come out.
Maybe we can change it to if(!cursor_screen_priv).
Is it a bug on XServer 1.6.0?
Thanks!
Best wishes,
Gordon
