Xpra: Ticket #395: Xpra session not wide enough for my screens

Hello

When I'm running the Xpra client on my primary workstation, I get the following warning:

2013-07-19 13:14:07,353 Server's virtual screen is too small -- (server: 5120x2160 vs. client: 5760x2160)
You may see strange behavior.

My workstation is equipped with 6 monitors in a 3x2 configuration, so my resolution really is 5760x2160. Any way to fix this? It means that any mouse actions on the rightmost 640px are put on column 5120, which forces me to place the window on either the center or left-most screens for it to work.

Any workaround that I can use on my server, to have it allocate a larger working area?

Short answer: bump the Virtual size in xorg.conf, and maybe the RAM too.


Long answer:

It looks like you are that you are using wiki/Xdummy (good), most of the resolutions from the xorg.conf file we ship should be supported. You can check this in the Xorg dummy server log file.

Optional but highly recommended: you can add a new resolution in there to match your configuration exactly using a modeline calculator, otherwise the next one up will be used (5120x3200) and this means things may flow down off the bottom of the screen at times.

Then it is just a matter of adjusting the "Virtual" option in the /etc/xpra/xorg.conf to the new one you have installed, or to the next resolution up (8192x4096) if you haven't. If you go for the latter, you will need to bump the RAM or you will see:

[138473.591] (II) DUMMY(0): Not using mode "8192x4096@10" (insufficient memory for mode)

I am closing this as WONTFIX because we don't want to increase the defaults just yet - very large screen areas like yours are still pretty rare, and changes to the defaults have other undesirable side effects: requiring more memory - but also DPI issues, etc.
