Support & Help Requests

#1

I’m running Ubuntu Mate on Ubuntu 16.04.1 and everytime i try to click on Displays icon, i get this

** (mate-settings-daemon:13725): WARNING **: Unable to start xrandr manager: RANDR extension is too old (must be at least 1.3)

if i run xrandr --version, i get this output

xrandr program version       1.5.0
Server reports RandR version 1.2

any help?

#2

It is complaining about the RandR extension, which is distributed by the libxrandr2 package and that is currently at version 1.5, not 1.2.

Install that package from the repository.

#3

but that’s i don’t understand… libxrandr2 is installed and updated…

libxrandr2 is already the newest version (2:1.5.0-1)

as i wrote in my prev message, if i run this xrandr --version, i get this output

xrandr program version       1.5.0
Server reports RandR version 1.2

and i don’t know what it means… it says xrandr version 1.5.0… but the server reports 1.2… what the heck?

What X display server are you using? What graphic card? Look in /var/log/Xorg.0.log to see what driver you are using. All of the display drivers in 16.04.1 should be 1.5 -

xrandr program version       1.5.0
Server reports RandR version 1.5

Did this occure after upgrade ?

#6

It’s a dedicated server, so no graphic card… i’m using x2goserver and before 16.04.1 i could open “Displays” option… after the upgrade anymore…

So you are connecting remotely . I did not know about this protocol . So basicly it seems that the remote server has version 1.2 of xrandr and your current machine has 1.5 witch are incompatible . They have to be the same version . Either find a way to downgrade xrandr on your local machine or upgrade the server libs . @Dave_Barnes is right .

@JohnnyKing94,

You really need to install the package I told you. :slight_smile:
Since you are using X2Go, you need to do it on the server where you are connecting to, since your local X server (if any) will not be used.
