Description Jethro Beekman 2013-11-09 22:10:29 UTC

When I activate intel-virtual-output, the cursor becomes invisible when showing the context menu (right-clicking) in certain GNOME/GTK applications. See https://bugs.kde.org/show_bug.cgi?id=327118 and https://bugzilla.gnome.org/show_bug.cgi?id=711582 . This is caused by intel-virtual-output resetting the source display root window cursor through display_flush_cursor(). I fixed this locally by changing "for(...) display_flush(...)" on line 2720 to start at i=1. This fixes this issue, but I'm not sure about the overall design of this tool and whether this fix will cause other issues.

    intel-virtual-output: Do not hide the cursor on the local/source display
    
    Whilst we want to take over and hide the cursor on the remote displays,
    on the source we need to not interfere with the host.

Works. This also fixes the cursor jumping around when starting i-v-p. Thanks a lot for the quick response and fix!
