Debian Multimedia :: Dual Monitor Jessie Gnome
Mar 9, 2016
In Debian Jessie Gnome with two screens, I would like to execute
xrandr --output HDMI1 --primary --right-of eDP1
xrandr --output eDP1 --rotate left
prior to showing the GNOME user logon screen. Unfortunately, all information I seem to be able to find on this appears to be relevant for pre-systemd Linux only.
The situation is that I have two monitors: One small tilted monitor on the left with 1024 x 768 which should be secondary and one larger landscape monitor on the right with 1920 x 1080 which should be secondary. Everything works persistently AFTER a user has logged on. However, after booting the system or after changing users, the small monitor becomes primary so (a) the user needs to logon using that monitor and (b) as the monitor is physically tilted, one needs to tilt the head to read it wihtout the xrandr commands.
If I can get beyond this issue, there is a second issue: While one can pick the primary and secondary monitor in Gnome, monitor numbers 1 and 2 seem to be fixed. This becomes a problem when using freeRDP to connect to a Windows server with dual monitors. Then, the smaller, secondary monitor is number 1 and thus, it is the Windows logon and primary screen. Is there a way to switch numbers 1 and 2 in Linux, for example somewhere in the grub configuration?

I have an external monitor attached trough a VGA cable to my laptop PC, with the monitor settings shown below. The problem is that when I have the external display connected, video players such as VLC or MPlayer display a black screen instead of the video, with only the sounds working. If I unplug the monitor everything works fine.
Setup Specs:
Dist: Debian Wheezy
Kernel: Linux 2.6.32-5-686
Gnome Version: 2.30.2
Laptop: Asus Eee PC 1000HE (10" LCD screen)
External Monitor: LG Flatron Wide L204WT, 20'' Widescreen LCD Monitor

I recently installed GNOME on my debian machine. I want to try using that as a second monitor for my windows 8 computer. I can't seem to find instructions on google, I want to try doing this wirelessy; is there freeware that lets me do this?

Here's the thing:
- Debian boots normally
- I get the login screen
- Once my credentials entered, I see only the grey foreground of the login screen for a couple of seconds, then a black screen with a prompt for like half a second and then I'm back to the login screen. No error message, nothing.
When booting in recovery mode and use startx, it works fine (it's my setup at the moment). From there, if I start gdm3 (systemctl start gdm.service), I get the black screen with a prompt and I can do nothing, I have to shut down directly by pressing the button.I tried to add Debian-gdm user to the video group (even if I don't use nVidia drivers), to replace gdm by lightdm and even to remove any display manager but the issue is not solved.Here are some outputs:
Code: Select all# dpkg-reconfigure gdm3
Job for gdm.service failed. See 'systemctl status gdm.service' and 'journalctl -xn' for details.
invoke-rc.d: initscript gdm3, action "reload" failed
Code: Select all# journalctl -xn
-- Logs begin at Tue 2015-12-29 19:16:26 CET, end at Tue 2015-12-29 20:20:55 CET
[code]....
Since removing gdm didn't change anything, I assume it doesn't have anything to do with it but still.

After I upgraded debian wheezy to debian jassie I cannot find how to switch off the computer from GNOME and XFCE. On GNOME I even cannot see a logout button. Where is it hidden?

Under wheezy, I could set gnome-terminal profile to partial transparency, i.e., to display the desktop wallpaper behind the text. (E.g., a picture of my girlfriend.) But after upgrade to Jessie, this option completely disappeared, and now I can only pick a solid color. Do I need to flip a setting or something to get this back? Am running default Gnome desktop (not fallback mode) though I think I only have 2D acceleration.

Updated old Eeepc 1005HAB to Jessie. Used to have a text file:
xrandr --output LVSD1 --mode 1024x600 --fb 1024x768 --panning 1024x768"
that I could run (twice in a row, it needed) to allow the scroling of the screen to see the bottom 1/4.
This no longer works.

I have did a clean installation of Debian Jessie today on my laptop and my computer.I use the Gnome 3.14.1 Desktop environment.
I installed Spotify-Client via PPA, and i installed the gconf-editor, gufw and Google Earth. Those 3 applications are not visable in the Gnome applications menu.
If i run then via the terminal, e.g. spotify-client, gconf-editor, gufw and google-earth, the applications are started. They seem to be installed correctly. I tried either running apt-get purge spotify-client gconf-editor google-earth-stable gufw, and reinstalled those applications, to no avail.
I even tried installing another desktop environment, mate-desktop. The shortcuts to the applications do exist in /usr/share/applications. Only not in the Gnome 3 menu. It's strange, because this problem happens both on my desktop and my laptop computer.
I run:
Debian Jessie 8.2.0 with Gnome 3.14.1.
Kernel 3.16.0-4
amd64 architecture
I also tried reinstalling Gnome-Shell and GDM. But it doesn't work.
Before, Debian Wheezy 7.9 was installed, and there was no problem. My Debian installation is fully up-to-date.

I have Jessie 8.3, netinstall and GNOME base. I want to switch to MATE and my question is hot to do it correctly.
I think it is impossible to do it by installing firstly MATE and the GNOME - both desktops should be crashed.
How to remove completely GNOME to be without any desktop environment? I can go to thext mode and run commands to delete the desktop but there is something more that I should do?

I had a hard time finding out how to change -- get to-- the simple scan preferences. There is no batten on the screen to open preferences window. I found two way to change the preferences on simple scan.
1. Easy way:
I found that when you run a program in gnome an icon of that application appears on top bar. If you click on that icon a window will appear and one of the items on that window is preferences, by clicking on that you could open preferences window, and change your preferences.
2. Hard way:
Go to applications and open dconf Editor
then go to org section click on it
then go to gnome section click on it
then go to Simple-Scan click on it
now you can change things

I'm trying to set up a dual monitor system with my Dell E7450 laptop with Debian Stretch and KDE 4.14.2. The graphic card is a Intel HD5500 with xserver-xorg-video-intel version 2:2.99.917-2. The first time I simply connected the HDMI plug, it recognized the monitor and it automagically set up the extended dual monitor. Then I unplugged the HDMI and KDE froze. Now every time I plug in the second monitor the laptop monitor goes black, the desktop goes on the external monitor and the mouse cursor moves only vertically along the leftmost edge of the monitor.

Just got a pretty fresh install of Debian/XFCE. Both monitors work out of the box on my 8400GS. I was unable to find an option to change it so I can span is as 1 work space instead of having them mirrored.

Just installed Debian 8, coming from Ubuntu12, it seems I cannot get my dual monitors to work as it should.
I want two monitors side by side, currently I have two identical outputs. I looked around a bit and register two possible problems.
root@bigcem101-debian:/home/bigcem101# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 0.00*
800x600 0.00
640x480 0.00
720x400 0.00
Hence, problem 1: it is as if there is only one monitor detected. Then I tried to look for Xorg.conf ..... and: problem 2 xorg.conf is not there. This seems to be normal but when I installed my Ubuntu years ago it was still there and one could manually set things. There must be something new I am missing.
Card:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV670 [Radeon HD 3690/3850]
It seems I have both ati and radeon installed.
root@bigcem101-debian:/home/bigcem101# X -configure
(EE)
Fatal server error:
(EE) Server is already active for display 0
I am clueless.

I just switched from Ubuntu to Debian and I am having trouble doing something that I found easy to do with Ubuntu. I have a Radeon R9 graphics card from MSI with dual DVI ports and I'm trying to get xrandr/arandr to detect my dual monitors but it only detects one. I've installed all the drivers and even installed the "amdgpu" driver from the Ubuntu repository but still not detecting. What drivers am I missing?

I am trying to set up dual monitors for lenny but nosuccess for the moment.
They were working fine for the same setup on ubuntu.
Using xrandr I get:
I read that virtual screen size could be the maximum part which is of no use in comparison to the current size.
So setting a virtual part in my xorg does not help much. If the above is right.
I have:

Pressing left, middle and right button of mouse at bottom and right edges or bottom left, top right and bottom right corners of the screen does not work with fittstool-2.0 on openbox in debian jessie with dual monitor.
Pressing left, middle and right button of mouse at top and left edges and top-left corner on the screen works correctly.
I use openbox on debian jessie. I do not install any desktop environment explicitly.
In the jessie, I installed gcc, make, libglib2.0-0, pkg-config, libcairo2-dev and libxcb1-dev.
I downloaded [URL] .... and confirmed that the sha1sum value of the downloaded file matches sha1sum value given at [URL] ....
I expanded the downloaded file by
Code: Select alltar -xvf fittstool-2.0.tar.gz
into fittstool-2.0 directory.
I executed with an ordinary (non-root) user:
Code: Select allcd fittstool-2.0
make
I executed with root privilege on the fittstool-2.0 directory
Code: Select allmake install
I executed the following with the ordinary user:
Code: Select allfittstool
and ~/.config/fittstool/fittstoolrc was generated.
I modified it as
Code: Select all[TopLeft]
LeftButton=gnome-terminal
MiddleButton=pcmanfm
RightButton=iceweasel
[Code] ....
gives:

I'm trying to get dual monitors working on a fresh install of debian from the netinst install cd. I did not allow the installer to download any packages and then manually installed xorg gnome-core & gdm using apt-get.
The monitors are plugged into the onboard vga and dvi ports of my motherboard. I believe the chipset is intel.
At the moment the displays are cloned.
I don't know much about xorg.
This is my xrandr output:

I upgraded to jessie today and I am having problems with my background. When I log in, the background tries to start on the external monitor but then it fails to load. I can change the background in settings but it does not show up. The background just becomes black and I am not sure why.

I have a Dell laptop (inspiron 1150) which was dual booting Windows XP and Ubuntu 9.04. I have successfully installed Debian Jessie Standard over the Ubuntu. I pre-partitioned using gparted-live to make a separate single partition for the Debian install. Guided partitioning was then carried out by the installer producing separate /, /home, and swap partitions. After installation, the grub menu shows an entry for Debian and Windows XP. I can boot Debian, but not Windows XP. The symptoms are the same as reported in other forums: A terminal is displayed, vanishes and the system reboots defaulting to the Debian boot.
The grub.cfg file for the Jessie system has an other-os entry:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
set root=(hostdisk//dev/sda, msdos2)
search --no-floppy --fs-uuid --set=root cc0ce0ab0ce091ae
drivemap -s (hd0) ${root}
chainloader +1
}
The original Windows entry for the Ubuntu install was:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
insmod ntfs
set root=(hd0,2)
search --no-floppy --fs-uuid --set cc0ce0ab0ce091ae
drivemap -s (hd0) ${root}
chainloader +1
}
The partitions produced by partman look OK (during the pre-partitioning I did not touch sda1, sda2, or sda3):
Code: Select all~ # fdisk -l
Disk /dev/sda: 37.3 GiB, 40007761920 bytes, 78140160 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code] .....
Partition table entries are not in disk order.
The os-prober found XP:
Code: Select all~ # os-prober
/dev/sda2:Microsoft Windows XP Home Edition:Windows:chain
So it seems that everything is in place, but there are perhaps important differences in the grub.cfg files. Are the two "set root" commands equivalent for example?

I am a experienced Windows person and my roots go back to DOS and the first version of windows. I am pretty good with computers but have little to no experience with Linux or Unix. About 30years ago I managed to make a painful transition from DOS and xTree Gold to Windows 3.1. Now I am leaving Windows behind forever...
I have installed Debian Jessie from a DVD that was made with the debian-8.1.0-i386-DVD-1.iso.
I have it installed and running with the Gnome desktop and now want to use the KDE desktop. As I understand it I have the files for the KDE desktop in my install and I see some KDE files the in the Packages app. But I don't know what I have, where it is, or how to use it.
I just cannot figure oout how to get the KDE desktop installed and running. If it is practical I would like to keep Gnome for now, switch to KDE as the defaultdesktop.
I have spend some hours googling and searching this forum and cannot seem to find anyting on switching or changing desktops from and with the Jessie install.
And if it can be done from Gnome that would be easiest for me because I am not much of a command line person yet and don't have a manual for doing that yet. But can use a terminal and enter commands if they are stated.

Installed Jessie and added the Nvidia Proprietary drivers. All looks good.
When I open the Gnome Tweak Tool it appears to be working fine but won't change anything. If I click on a check box the check appears for a split second and then disappears. Tried re-starting a few times, same. Haven't found anything relevant on the net yet.

I did an in-place upgrade to Jessie today and I can only get the GNOME Classic desktop, which I have to select when I log in. I had started to get used to the default desktop in Wheezy, so I'd like it back if possible. When I select gnome system default, I get my desktop, but no menus or anything I can click on at all. All I can do is ctrl-alt-delete and reboot or shutdown. I run it on a Lenovo Ideapad U410.

I am on kubuntu 9.10 x86_64
I just got my new video card: nvidia 9500 GT to setup dual monitors.
The video card has 2 dvi output to support dual monitors
Monitor 1 is connect to dvi
Monitor 2 is connect to dvi using a vga adaptor
I can't seem to get dual monitor to work?
From system settings -> monitor, i see 2 vid outputs one is DVI0, the other is VGA2. what's odd is i can set up different screen resolution for each monitor, but I only see one desktop, both monitors show the same desktop.
How do i get each monitor to show it's own desktop?

I noticed in the new Ubuntu 11.04 with Unity, when in dual monitor the icon of skype is not placed in the tray when "closed". It is only placed in the background, so that I have to kill the process and open a new one. To be sincere, I see a strange aspect of the entire tray when in dual monitor. Is anyone else noticing the same?

I have tried to setup a workstation with 3 monitors on two ati videocards, the goal being to span the desktop across all of them.
The process was not difficult at all, but after login X11 crashes and I am left with a console. I am fortunately able to login in safe mode, but I would like to ask for help in debugging this issue.
Here I will try to give as much detail as possible, starting with my system specifications:
Code:
The first card, the ATI Radeon HD 4650 is capable of running two monitors at the same time. The monitors, for all it matters, are three identical ACER P206HV 20" connected with their analog interface (due to missing cables which I will buy soon). Resolution 1600x900 each. My motherboard is an AsRock 870 Extreme3 mounting an AMD Athlon II X4 640 3 GHz processor and 8 GB of RAM.
When asked by Ubuntu, I installed the ATI Caralyst driver version 11.6 and set it up for using Xinerama.
As I said, this setup works fine if I login in safe mode, but crashes X11 otherwise (even in classical mode - no Unity). By inspecting the logs (attached) I found this (notice the segfault)
Code:
As a test, I tryed to configure Catalyst without Xinerama, an this works, but of course I end up with two separate desktop, which is not what I want. In this mode, xrandr seems to work correctly
Code:
After some research I found that XRandR does not support desktop spanning over multiple GPUs, so Xinerama is the only way to go in my case. Since the two are not compatible with each other, after login in safe mode I see that XRandR is disabled
Code:
One more test consisted in disabling the XRandR module in the config files, as found in some posts: edits in /etc/X11/xorg.conf
Code:
configuring the ati driver:
