Report is about resizing of Unity7 (2d). Long gone, not supported anymore.

Hi Christoffer,

I submit the below issue as a bug to X2Go BTS. I file it against X2Go  
Server for now, however, a real fix is probably needed in nx-libs  
xfixes extension. So we may reassign this issue later...

It is very likely that not nx-libs caused this, but an upgrade of  
x2goserver to version 4.0.0.0.

In 4.0.0.0 we have added a configuration file (/etc/x2go/x2goagent)  
that disables the GLX and the XFIXES extension. Obviously, disabling  
the XFIXES extension causes problems in precise's Unity and the screen  
resolution is not set properly anymore.

For now, please comment out this line in x2goagent.options:

--- /etc/x2go/x2goagent.options.orig    2013-01-09 12:27:24.755957564 +0100

It seems that the XFIXES extension is used to detect the clients  
screen resolution and hand it over to the desktop shell (or xrandr?).

Still a little in the dark, but the above change in x2goagent.options  
seems to solve the reported issue. However, enabling XFIXES in  
x2goagent again leads to other problems, that were lately discussed on  
IRC. Do what causes least problems for you...

Mike's question at the other devs is: wouldn't it be better to comment  
out the recommended extension disablings as opposed to disabling the  
extension right away and expecting not-so-well tested errors?  
Feedback? Opinions?

Greets,
Mike
