Re: [X2Go-User] x2goserver on Ubuntu Mate 15.04 with 4k monitor and high font-rendering DPI
I saw this setting but for some reason it didn't affect anything when I changed it to 96. Could it be caused by the fact that ongoing (not logged out) session was active on the server (physical console) while I was trying to remotely connect to it via X2Go?
The only way I found to connect to that server with reasonable DPI was to create a separate user that runs default settings, but that doesn't seem to be a good fix.

Hello,
I'm looking for a way to run *x2goserver* on *Ubuntu Mate 15.04* which is living on computer with *4k monitor* attached. I changed *DPI* settings in Control Center -> Appearance -> Fonts -> Details to *168* to let all applications look good when I work on that machine locally.
When I connect to this machine using *x2goclient* running on another Ubuntu Mate 15.04 (attached monitor has resolution of 1680x1050, fullscreen mode) I am seeing *huge* fonts (as expected) because it also uses dpi of 168 for that remote connection.
*My question*: would it be possible to run *pre-connection* (and then post-connection) script(s) to temporally change DPI to "normal" value of 96 before and recover it back to 168 upon completion of the x2go session? I guess it can be done by running "*gsettings set org.mate.font-rendering dpi 96*" command but I'm not sure where to include this command. And also I'm not sure how to protect against abnormal session termination... what if session will terminate without recovering DPI back to 168?
There's a setting in the X2GoClient GUI to force a DPI value, doesn't that work for you? If no, why?

That might be - never tried that, I'm usually logged in either locally or remote, but not both. We'll have to wait for one of the Devs to chime in here.

What exactly are you doing, anyway? It seems like you are starting a shadow session, i.e., connect to the already running "local" X server on the server machine?
The DPI setting in X2Go Client controls the private X server's - i.e., nxagent's
- DPI value. There's a caveat though, in the sense that desktop environments can and most likely will overwrite that.
The only way I found to connect to that server with reasonable DPI was to create a separate user that runs default settings, but that doesn't seem to be a good fix.
X2Go provides support for hooks via its "extensions" support. I guess it's not properly documented anywhere yet, but the basic idea is to put scripts into /usr/lib/x2go/extensions/. The "targets" in there are sort-of self-explanatory.
N.B.: the amount of "targets" available may differ between release and nightly versions.
All this said, I think a separate user is the "cleanest" and best-working idea.

I wasn't looking to start a "shadow" session to access existing session. I just needed to use some software that was installed on that machine so fresh session worked fine. I will try the "extensions" approach for testing and will stick with a separate user scenario for main needs in future. Thank you.

I switched recently from KDE 4 to MATE (Arch Linux) and can see the same behaviour with MATE: x2goserver/nxagent ignores the dpi settings set in x2goclient.
I had not had time to investigate this further and for now worked around that by placing two launchers on my desktop and running them manually in the current session:
For local sessions: gsettings set org.mate.font-rendering dpi 107
For x2go sessions: gsettings set org.mate.font-rendering dpi 96
It works on the fly, only some apps (skype) need to be closed and restarted.
I believe one could use .config/autostart/ and some script with tests of the environment to set the proper DPI during log-in phase. This would resolve the issue with uncleanly terminated sessions. Perhaps it may not work for published apps.
I hope to look at the issue later (well, just a cheap promise...)

In Mate, if you go into System->Preferences->Look and Feel->Appearance,then select the "Fonts" tab, in the lower right click on "Details", then in the upper left you can set the resolution to whatever DPI you want. This works with X2Go, NX protocol with Remmina, and pretty much everything else I've tried.

It surely does, because it is the same as the command: gsettings set org.mate.font-rendering dpi XX
Using GUI is great for a once-set-do-not-touch-anymore action, but when you need to change the DPI often...
Anyway, the aim is to use DPI settings as per x2go client setup. It seems that in MATE, once the user sets hiw own value, the DPI from xorg.conf is ignored (which sounds logical but does not fit the bill for our use). xrandr --dpi XX in the running x2go session also does not have any effect.

So basically, what you'd need for MATE is something that reads the desired DPI value from an ENV var or from some file, then issues the gsettings command you quoted above, and this would have to run on every session startup and reconnect, right?

Yes, something along those lines.
Part of it could be done by x2go (startup, reconnect, terminate) and the other part by the user, eg. via $HOME/.config/autostart (for situations when x2go session terminates uncleanly and then the user starts a local session).
The latter could be done through autodetection, but that approach would make any user specific DPI for local session obsolete after re-login...
Once I have time I try to look at it, because running the gsettings command once the user is logged in is suboptimal (e.g. Skype has to be restarted to reflect the new DPI).

Wondering if anyone has considered an x2go plugin for Remina?
Regarding 15.04, I'm using on a workstation, but loaded onto a server Ifound it too unstable and reverted back to 14.10.

For what its' worth, xrandr is broken if you have xcinerama enabled, atleast with the Nvidia drivers.
