[pve-devel] [PATCH qemu-sever v12 1/6] enable VNC clipboard parameter in vga_fmt
Markus Frank

Fri Sep 8 13:05:59 CEST 2023
added option to use the qemu vdagent implementation to enable the VNC
clipboard. When enabled with SPICE the spice-vdagent gets replaced with the QEMU
implementation.
This patch does not solve #1406, but does allow copy and paste with
a running X-session, when spice-vdagent is installed on the guest.
