Dual Monitor Problem at restart?

Wed Sep 22, 2010 5:08 pm
So each time I restart or logoff/logon in KDE 4.4.4, my settings for dual monitors is lost. I tell KDE to have the right monitor position itself to the RIGHT OF the primary monitor, but each time I restart it resets the position so that what is on the primary monitor is duplicated across both screens?

Anyway to make my preferences permanent? Thanks in advance.

Hi,

I have the same problem and it's really annoying.

I was using the default kde ship with ubuntu 10.04, I then upgrate to 4.5.1. (as descript on the kubuntu website) And the problem is still present.

Not only that my monitor settings get reset each logout, but my activies, taskbar, ...

Thank you

Can you post more information about your setup? Graphic card? Do you use krandr to set up your monitors? Is it autostarted by default?

I personally am running an Nvidia 8400GS video card and I've not heard of krandr so I suspect I'm NOT using that. I'm running with OpenSUSE 11.3 and KDE 4.4.4 came with it. I haven't tried updating KDE but would try that if it is suggested here?

I would guess you use Twinview then, can you post the contents of /etc/X11/xorg.conf here please?

Section "Device"
Identifier "vboxvideo"
Driver "vboxvideo"
EndSection

Section "Screen"
Identifier "vboxvideo"
Device "vboxvideo"
EndSection


Section "Device"
Identifier "vmware"
Driver "vmware"
EndSection

Section "Screen"
Identifier "vmware"
Device "vmware"
EndSection


Section "Device"
Identifier "cirrus"
Driver "cirrus"
EndSection
Section "Screen"
Identifier "cirrus"
Device "cirrus"
EndSection


Section "Device"
Identifier "fbdev"
Driver "fbdev"
EndSection
Section "Screen"
Identifier "fbdev"
Device "fbdev"
EndSection


Section "Device"
Identifier "vesa"
Driver "vesa"
EndSection

Section "Screen"
Identifier "vesa"
Device "vesa"
EndSection


Section "ServerLayout"
Identifier "Layout"
Screen "vboxvideo"
Screen "vmware"

EndSection

If you used KRandR ( System Settings Display module ) to set your default monitor, ensure that "krandrtray" runs on startup.

One other thing - both monitors are connected to the same card, right? If I remember correctly that's necessary to get Twinview to work.

Also, have you installed a Nvidia driver? I would start with that if I were you (you should be able to do it from YaST).

as much as i love KDE, this fairly major "mishap" is a prime example as to why gnome is currently the linux desktop manager of choice for most people.

i have the exact same problem happening on two of my machines, one using a radeon x700, the other using an AMD RS integrated graphics chip. both run the open source amd driver on kubuntu 10.04. krandrtray is used to configure the monitors and is started upon bootup.

furthermore, the default settings it reverts to upon reboot are the maximum resolution supported by both monitors (1152x854), with cloning of the monitors enabled (instead of the previously selected "right of"). surely it should default to the maximum resolution for both monitors and align them next to each other, rather than clone them. this is what all other OS do.

Are you using the NVidia binary drivers? When you configured the the desktop, did you use a tool provided by Nvidia or a tool provided by KDE?

I used the basic KDE tool to configure the desktop. I could try downloading and installing the NVidia drivers if that might fix things?

How do I have krandrtray run at startup? Thanks!

Copy /usr/share/applications/kde4/krandrtray.desktop to ~/.kde4/Autostart

That has it auto start now (with a confirmation) but it doesn't do anything to correct the problem of having to tell KDE to keep the right monitor display to the "Right Of" the primary monitor display.
