I wondered about that one, too. Usually I do the following at the console: xhost + xrandr --auto xhost - Good news: In a few days, Xubuntu 14.04 will release, supporting monitor hot-plugging: details

The display ids in X follow the form :<screen>.<display>. Contrary to intuition, all the monitors in a multiple-monitor setup share a <screen>, but have varying <display>. The screen "first" in the setup is :0.0, and others are :0.1, :0.2, etc. The final command is xcalib -invert -alter -display :0.1

I've stuggled with SIS graphics cards on Ubuntu, so I know your pain. Arch Linux has got SOME support for SIS graphics card users, depending on what SIS chipset you are using. You may not want to use Arch Linux, but the information here may be helpful as it has got some information on setting up the x.org config file for dual head display. ...

I also had a flickering with my second monitor. Interestingly only when I used DisplyPort. I had no problem with DVI. I could solve the problem within the AMD Catalyst Control Center by setting the Image Options from "Use display for scaling" to "Use graphics processor for scaling" on both monitors. Now I have no problem with flickering anymore. See image: ...

I'm having the same problem with Lubuntu 12.04. Your workaround with the pos argument does not work for me. What works for me is calling xrandr twice, with different resolutions: DISPLAY=:0 $xrandr_command --output HDMI1 --mode 1024x768 DISPLAY=:0 $xrandr_command --output HDMI1 --auto It's causing some ugly flickering, but does its job. And it saves me ...

This is my workaround. nano ~/.kde4/Autostart/setupscreens.sh fill with the following code #!/bin/bash foo=$(sed '3q;d' $HOME/.kde4/share/config/krandrrc) ${foo:16} save (ctrl-o) and exit (ctrl-x) now make it executable chmod +x ~/.kde4/Autostart/setupscreens.sh What it does is run the xrandr command generated by the system settings GUI when you ...

The problem is your card. It can only handle 1x dual link dvi at full resolution, the second is single link dvi. 1 gb or ram is not enough to push 2560x1440 on 2 monitors. This is why you are only getting it on 1 monitor. The card can drive 2 monitors at 1920*1080 just fine but you are not going to get 2 at 2560*1440. 2*(1920*1080)= 4,147,200 normal ...

I stumbled across a solution to this accidentally. Going into "Software & Updates", then the "Additional Drivers" tab and changing the video driver from "X.Org X server" to "NVIDIA binary Xorg driver" (the one that's listed as proprietary and tested) fixed the problem.

I experienced this problem with a SANSUI HDMI/PC tv/monitor. My issue resulted from the SANSUI incorrectly reporting it's EDID. The solution is to use xrandr to add a mode manually to the problematic device. If the mode you want to add to your output already exists you can skip steps 2 and 3 Type "xrandr" without any arguments which by default will list ...

Just open the Displays settings and turn off the laptop display (Built-in Display on the picture below). If you unplug your external monitor it will come back again. And of course if the HDMI monitor is re-plugged, the laptop display will turn off as expected.

Not sure if this is related but I had a similar problem with lenovo w500 laptop and red hat. My problem was that graphics adaptor has a bios option to conserve battery but only works in windows. Had to enable offboard graphics adaptor full to get it to work. very difficult to tell if this applies to you. Might try posting more info from system log and ...

So you want to use 3 monitors total? Will you be using one GPU? What kind of GPU will you be using? It should be as simple as plugging them in and going to 'System Settings -> Displays' to configure them the way you'd like. You can move them around, set resolution, etc.

Press the windows button to open Dash. Search for Displays, and open it. You should find everything you need right there, but for a quick fix, select the checkbox Mirror displays on the right side. Most likely, the windows are considered to be side by side. Moving the mouse pointer out of the screen towards left or right should get you to the other ...

On say Google chrome you can change the place where you would download files. Say you have a file called downloads on the right monitor you can change the place to /desktop/downloads. If you are using any internet browser there is a settings which may have where your downloads folder is. Hope I helped. Edit: This is not a mundane question as there is no ...

You can get a lot of information from /var/log/Xorg.0.log. Look for Errors. Also check out /etc/X11/xorg.conf. xorg.conf used to be necessary for setting up X properly, but my experience has been that it usually gets in the way now. I have a newer version of Ubuntu and a newer graphics card, but I run without any xorg.conf file and don't use the ...

Have you tried / do you see the TwinView option? ... Maybe it could help prod things further..?

I had a similar problem recently. I could've made a custom Xorg.conf file but that would've undermined all the nice new automatic configuration when I connected to other monitors. I re-wrote the corrupted EDID instead: Here are some reading materials: ref: https://en.wikipedia.org/wiki/Extended_display_identification_data#External_links edid-rw: ...

You'll have to compile FreeRDP from sources because Multi-Monitor support is only available in versions >= 1.1. Visit this page to get instructions and a list a build dependencies. Then you'll be able to start a connection from a terminal like this: xfreerdp /multimon /u:username /v:server_hostname:server_port

You can run rdesktop -f or run rdesktop -f <width>x<height>. -f Enable fullscreen mode. This overrides the window manager and causes the rdesktop window to fully cover the current screen. Fullscreen mode can be toggled at any time using Ctrl-Alt-Enter. -g Desktop geometry (WxH). If geometry is the special word "workarea", the ...

I'm also having this problem, also with an AMD GPU. My current drivers are fglrx 13.10.10 [May 23 2013]. A workaround is to run Software Updater from Unity. 2x 1TB drives 8 GB memory dual boot windows 8.1 (each OS has its own physical drive) AMD Radeon 5850 Software Updater has appeared in the past, though it seems set on not showing itself right now. ...

I had the same issue and discovered that I had to extend the height as well as the width to make it work (thanks to ThomasKl's edit to his answer for this question). Try Virtual 3360 3360 in the Display subsection.

This is the most common with HDMI and display port but some DVI and VGA monitors can do it too I'm told. DVI is hit and miss and I've never personally encountered a VGA one that does this. When you power off the monitor it ceases to be communicating with the computer. On HDMI at least the easiest workaround I found was to cover pin 19 with a piece of ...

I believe the displays used in xrandr are case-sensitive. I noticed you said vga-0 instead of VGA-0 so double check!

Display parameter is irrelevant. Trick is setting coordinates correctly. All screens considered as whole. Say you have two screens, primary has 1680x1050 secondary has 1024x768 Your coordinate space is : 2704x1050 ( sum of two screens width and the biggest height ) to capture second screen -x=1680 < width of primary screen -y=0 < default ...
