Re: [Xen-users] Show DomU login dialog instead of Dom0's

[Markus Mehrwald <mehrwald@xxxxxxxxxx>]

I tried this and it looks like as it will work but I have still some 
problems.
I boot my system like every day and run the commands provided:

X :1 vt1 &
vncviewer -display :1 -FullScreen localhost &

and everything works fine. I have my Windows running on tty1 and the 
Dom0 on tty7 as I wanted it. But using the same commands in 
/etc/rc.local the vncviewer says that he could not connect to the 
server. Sometimes after this error I cannot use my PC locally and I have 
to kill all running X servers via a ssh connection.
Maybe the hvm is not running when the commands from rc.local are 
executed but in my mind it should because rc.local is the last script 
running during boot time.
The second thing which is not that important (maybe I can use another 
implementation of vnc) is the point curser shown in addition to the 
native cursor of Windows. The problem is that both cursors do not have 
the same speed so sometimes the X cursor stops at the border of the 
screen and the Windows cursor is elsewhere on the desktop. I tried 
DotWhenNoCursor=0 but it had no effect.
Greetings,
Markus
