I have tested here with Xdummy and that worked fine.
Can you share your Xdummy command if different from the one in the
wiki?
I am using the one that gets generated in the xpra.conf like so:
export DISPLAY=:10
xpra_Xdummy -noreset -nolisten tcp +extension GLX +extension RANDR
+extension RENDER -auth $XAUTHORITY -logfile
${HOME}/.xpra/Xorg.${DISPLAY}.log -configdir
${HOME}/.xpra/xorg.conf.d
-config /etc/xpra/xorg.conf $DISPLAY
Thanks for sharing, but ould not figure out 'xpra_Xdummy' :
http://xpra.org/trac/browser/xpra/trunk/src/scripts/xpra_Xdummy
Thanks for very useful pointer:
But how to specify the screen resolution with xpra_Xdummy (as you have
suggested as quoted below)? In my case I need 4K in the virtual x
server in server and 1K in the client, fyi
export DISPLAY=:10
xpra_Xdummy -noreset -nolisten tcp +extension GLX +extension RANDR
+extension RENDER -auth $XAUTHORITY -logfile
${HOME}/.xpra/Xorg.${DISPLAY}.log -configdir ${HOME}/.xpra/xorg.conf.d
-config /etc/xpra/xorg.conf $DISPLAY
Use xrandr to change the resolution.
How to make changes in the virtual X server with xrandr. It could be
possible with xrandr, however my requirement is 4K in the server while
displaying the same content in FullHD or lower in the clients. It is a
bit confusing how to use xrandr to get two different resolutions in
server and client! Would you mind elaborating?
Using xrandr to change resolutions can be useful in two cases:
* you start the Xvfb yourself and use xpra in shadow mode, in this case
xpra does not try to change the resolution for you
* you tell xpra not to do randr (with XPRA_RANDR=0)
If you are certain that you will only need a single resolution, then you
could also use a customized xorg.conf
The "desktop-scaling" option in 0.16 looks easier to me than either of
those options.
That's assuming that you are using Xdummy. If you use Xvfb, then this is
all moot.
Cheers
