[EN] Dual monitor setup screwed after upgrade to jessie

[ckosloff]

Hi,

I was in Debian stable and updated all my machines to testing (Jessie). No problems with those that had only 1 monitor, but I lost the dual monitor setup completely.
KDE no longer has the option for multiple monitors in the Display applet.
I asked h2 (smxi) and he sent me here, hope you can help.
Here is some info on my system:
ckosloff@papimalo:~$ inxi -G

Code: [Select]

Graphics:  Card: Advanced Micro Devices [AMD/ATI] RS480M [Mobility Radeon Xpress 200]
           X.Org: 1.12.4 drivers: radeon (unloaded: fbdev,vesa) Resolution: 1440x900@59.9hz
           GLX Renderer: Gallium 0.4 on ATI RS480 GLX Version: 2.1 Mesa 9.1.6

My primary monitor is LVDS and my secondary monitor is VGA-0.
Primary set to the right of VGA-0.
All this worked fine in stable but it got messed up in the upgrade.
All drivers (radeon, fbdev, vesa) are installed from the jessie repo.
I need some help to configure xorg.conf, it is messed up.
Sorry for the long post, here it is:

Thank you very much.

[towo]

I would delete the xorg.conf and set the output with xrandr.

[ckosloff]

Hi towo,
I was thinking on that, only that I don't know to "set the output with xrandr", please elaborate. Thank you.

[ckosloff]

I deleted xorg.conf and loaded arandr from jessie repo. Still not working.
I can only get cloned outputs.
The multiple monitors tab has disappeared from the Display applet in System Settings, so I think that there are other issues.
At a certain point I got this warning in console:

(gconftool-2:8695): GConf - WARNING **: Client failed to connect to the D_BUS daemon: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

now try

Code: [Select]

xrandr --output LVDS --auto --output VGA-O --auto --left-of LVDS

any errors?

[devil]

Besides that, if you are using KDE SC, KDE 4.11.1 comes with kscreen, a new utility to fulfill your dual monitor needs.

[ReinerS]

Has there been found an solution for that lately ?

I am experimenting from time to time with xrandr and nouveau to get away from the prop.nvidia-driver but have also experienced this switch to "clone-mode" as soon the second monitor is "touched". This happens also when the prop. nvidia-driver is used instead.

This is my current xrandr-line for an GT8800 Nvidia-Card:

Code: [Select]

xrandr --fb 3200x1200 --output DVI-I-0 --mode 1280x1024 --pos 0x0 --panning 1600x1200 --rotate normal --output DVI-I-1 --mode 1280x1024 --pos 1600x0 --right-of DVI-I-0 --panning 1600x1200 --rotate normal --output DVI-I-2 --off --output DVI-I-3 --off --output TV-0 --off

kscreen unfortunately is no help in this matter either.

Reiner

[Smon]

Thank you ReinerS, --fb solved my problems.
I have 2 Screens with 1920x1080 and at every third boot, the panning was at 2880x1080 at both of them.

[ReinerS]

@Smon: Do you have also this "cloned" output or did you solve this?
And if so which type of graphics card do you have?

regards

Reiner

[clubex]

Somewhat of topic but of interest if you use 4 monitors and NVidia drivers:

http://www.muktware.com/2013/10/nvidia-cripples-linux-drivers-windows/14883

[Smon]

@ReinerS: I have a nvidia card, but today the problem appeared again :/
Thats my setting:
xrandr --fb 3840x1080 --output DVI-I-2 --rate 60 -s 1920x1080+0+0 --left-of DVI-I-3 --output DVI-I-3 --rate 120 -s 1920x1080+1920+0

Most of the time it is working, but sometimes ...
Only Solution is to go in nvidia-settings.

[ReinerS]

well, with nvidia-settings all is ok so far within kde.
But in xfce the "panning" area gests scrambled and is unusable.
And xfce was/is my preferred desktop envirtoment. So I came to experiment with xrandr and nouveau where I always have this clone-output.
And it doesn't care wether I use  a --pos YxY, --right-of, --left-of option for the second monitor.

But maybe I will experiment with the --s option next time.

regards

Reiner

basically, after setting up the monitors to your liking in nvidia-settings, store the configuration to a temporary file in your home. have a look at it and create the necessary 20-nvidia.conf accordingly. do not use mouse or keyboard sections, though

NOTE: this is for proprietary nvidia only... when using free xorg drivers for ati/intel/nvidia, you should rely on the kde/xrandr settings.

btw. i suppose, this is also why Smon had problems with xrandr and nvidia, and had to use framebuffer option
