Ubuntu :: HD4870 Dual Display - Cannot Seem To Swap My Primary Display
Jan 8, 2010
Hi I am new to ubuntu and am having major problems setting my displays up. my setup is a hd TV to the Left of my pc monitor, i have managed to configure catalyst to let me have a main display with the second display being an extension of the first, the problem is i cannot seem to swap my primary display, at the minute my HDTV has all the taskbars and everything on it while my pc monitor is just a blank background, i would like it so i could start a film playing for my children, then drag it across to the HDTV while i can still use my pc in the background.

I just installed Ubuntu 9.10 this evening. I have a Nvidia Geforce 8500GT video card with two monitors hooked up (one to the cards VGA, the other to the DVI). I installed Nvidia drivers and Ubuntu is working with both monitors fine.
The problem I am having is it chose the monitor plugged into VGA as the primary (uses that monitor for the toolbars) when I really want them to go on the monitor that is plugged into DVI. Is there anyway for me to switch which monitor Ubuntu treats as the primary?

I believe I'm right in thinking the type of graphics card I have is relevant somehow to this, so after some googling I think I worked out mine is Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller.

I have an ASUS 1000HE laptop running Lucid 10.04 (Desktop not netbook version) which I have connected to an external display (LCD). I don't intend to use the laptop by itself anymore therefore I have configured the display properties to turn off the laptop display and use the external display as primary. However, when the PC enters 'locked mode' or the display powers down after a defined period of time (as set in the properties) when I wake the PC and the display, it turns the laptop monitor back on .... switches the laptop screen to primary display (i.e. with the panels etc displayed on it) and extends the desktop to the external display! The only thing I can then do is go back into the configuration utility and turn the laptop monitor off again and boom, everything is fine and dandy displaying on the external display again! I don't really want to have to do this every time I come back to the PC after it has been locked nor do I want to write a script (if it can be avoided) to deal with it!

I have google'd the crap out of this and have yet to find a "solved" forum. I currently have 2 sapphire ati 5770's in xfire. I also have two monitors. My (preferred) primary display has a dvi input and my other display is hdmi. I have them both plugged into only one of the cards. For some reason it keeps setting the hdmi display as the primary. And I want them in extended view. The ATI CCC suite does not support changing the primary monitor and I have tinkered with the xconfig but I do not really know what I am doing, so I have ultimately not been successful. here is my xorg.config file.
Code:
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection
[Code]...

I have a Radeon HD 5830, running 3 monitors on 10.10 64bit with the 10.6 video driver. The three monitors ( from left to right ) :
DFP1 : 1152x2048
DFP2 : 1920x1200
CRT1 : 1360x768
The problem I'm having is getting the middle monitor to be the primary one.
Running
xrandr --output DFP2 --primary
puts the panel on the middle screen but my docky and icons stay on the left screen. Flash videos also open up on the portrait left monitor which looks awful. Ideally I would like the icons on DFP1, docky on P2 and flash videos to open on P2. But I would definitely settle for everyone to be on the middle screen and drag it around as I please.

I am posting this to hear if there are others with display issues on Dell E6500 laptop with the Nvidia Quadro NVS 160 driver. This problem is starting to annoy me a great deal, but I am uncertain how I should move forward. In short; I have Ubuntu 10.04 x64 installed on my Dell E6500 laptop. When using only the laptop, everything works great. The second I plug it into the docking station (the laptop lid closed) and want to use my two external monitors (Dell 2001FP) I'm in trouble. I cant see anything and what I get is a 'DVI: Cannot Display this Mode' on the primary monitor - If i try a regular VGA cable I get nothing but a black screen.
I have played around with the Nvidia config but it cant find my monitors and therefore I cant do much. I am aware of the various "hack the xorg.conf" options, but I before I do that I wanted to see if others had experienced the same thing. I had hoped that we were pasted the hack stage and that primary functions such as display would work by now.

Normally I use disper to enable my external monitor, but I don't think I can force the 2nd monitor to be primary. [URL]
I've played around with nv-control-dpy included in the nvidia-control source, but I haven't figured out how to do it yet. How to get: [URL]
This is a laptop, to which I connect an external hdmi display when I get to work. dipser -e extends the desktop for me, but the laptop remains the primary desktop (holding the panels etc). nvidia-settings can set primary monitor for me, but I want to use the cli.

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

I just installed Ubuntu 10.04 64 bit and I'm having a problem with the graphics card.
I have dual screens, and I'm using the default card. My Left screen is perfectly normal but my right screen has a black bar, roughly 2cm wide, along the left hand side of it. And that hole screen is shifted to the left 2cm (so if I maximise a window in it you can't see about 2 cm of the right edge).
I'm not sure why this is happening. Worked on Karmic. Haven't installed anything, just the defaults. My graphics card is a Radeon HD 4870.
Also, I couldn't get Compiz to work with this card on Karmic, is it possible to get it to work here on Lucid? I heard they were improving the drivers. If so, how?

When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

I just upgraded to Fedora 14 and found that my KDE "default" display (i.e. the display where the default panel is situated) has changed from LVDS1 to VGA1, which is not reversed from Fedora 13. In fact, everything that used to be associated with LVDS1 is not associated with VGA1 and vice versa.

I have a one ubuntu machine, that has two displays are fixed, and I used to have a vnc connection from a debian pc. but the thing is each time I connected to this ubuntu pc, i usually get my connection to the primary display. Is there a method, that I can display both displays, at once, and I have a scroll bar to scroll between each of them. I tried to specify a port as,
xvnc4viewer 192.168.1.1:5900 -> goes to the primary display
xvnc4viewer 192.168.1.1:5901 -> goes to the secondary display
but Isn't there a method that I can view both of them at once?

I just installed lucid on my laptop with a second screen. Unfortunately, I cannot display any video. Neither on the laptop screen nor on the second external screen. In contrast, rebooting without attaching the external screen allows me to display videos again.
I never experienced this kind of behavior with Ubuntu 9.10.
Graphic card: Intel 945
Let me know if you need further information.

New machine with an ATI 5770, with a fresh install of Ubuntu 10.04 (lucid, 64-bit). What a mess! As reported elsewhere, the initial install sometimes came up with a black screen, or corrupted displays, different each time. After several retries, I had a display that was corrupted but barely readable. The installed Ubuntu booted, but also had a corrupted display, just barely readable. I was just able to make out the hint that I should use the proprietary drivers, so I booted into safe mode and enabled them. Afterward, the display came up correctly.
This is ok for me, as a long-time Ubuntu user. But it really is like a trip back to the bad-old-days of Linux: you really cannot expect anyone but a geek to get through this. And the is the LTS version of Ubuntu? I use two monitors, to provide a double-wide single desktop. When I log in, the second monitor displays random noise, and is entirely unusable. I have to use System-Preferences-Monitors to switch the second display off, then switch it back on, and then everything works fine.

Does a KVM software solution exist that will allow you to utilize two monitors on multiple systems? I'd like to hook up my MBP to my displays, but have the flexibility to switch back to Windows/Linux on a whim.
I have two monitors. I would like the ability to use these monitors from all of my computers using a software-based KVM switch. The alternative is stopping my workflow and manually hooking up the monitors, which is the process I currently use and the process that I'm trying to automate. I'm wondering if such a product exists.

I have wheezy installed on my laptop with XFCE 4.8 and kernel 3.14 from backports. The laptop uses Nivida-optimus:
Code: Select all00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation Device 1292 (rev a1)
I installed the proprietary bumblebee-nvidia (version 3.2.1) as per the instructions in URL...The problem is that when I connect a monitor to the laptop, the image is duplicated with only part of the screen showing on the second monitor. The monitor itself is not detected in the display settings or arandr / xrandr, so I can't change the resolution or set dual display, etc. Here is the output of xrandr:
Code: Select all$ xrandr
xrandr: Failed to get size of gamma for output default

I am Currently attempting to set up a Dual Screen setup at my work but seem to be having some strange results. For some reason the O/S is only recognising one of the monitors, it knows exactly what the Make and model of the monitor is but doesnt appear to know that there is another monitor plugged in. It constantly says that there is 2 screens plugged in but lists the second screen as "CRT-0" even if no DVI cable is plugged into the second screen. This has really troubled me and has really got me thinking. I have set-up other Dual-screen setups with exactly the same hardware previously and it has worked fine? I am using a Lenovo A58 Tower with an Nvidia Quadro FX-380 Graphics card that I know is capable of dual Dual-link DVI output! With 2 x LG W3000-H Monitors running Fedora 12.

I am having a few strange issues with my new SUSE 11.3 install. This is my first time attempting to use it as my full time OS, so I can't say if these problems existed in previous versions.
1.) When I configure extended desktop, it works fine, but the settings do not save. Anytime I reboot my system, I have to reconfigure the Dual Display settings
2.) If I enable openGL effects, or use an OpenGL screen saver my system locks up and I can not restart X. (I have to power cycle the computer)
3.) I get corrupt icons sometimes in my system tray and desktop. (They look like a TV that is tuned into a non broadcasting number)
I have a Quadro 1700, and I read about installing the NVIDIA drivers instead of the ones that come with SUSE.

I have two Ubuntu 10.4 machines (and Ubuntu continues to hide more and more xorg.conf config such that I no longer know where to find it). One is a laptop running dual headed - DP1 is the internal screen, and VGA1 is an external monitor; both are running at 1600x900. The other machine is a desktop running both VGA1 and HDMI1 (which is actually a display port with a DVI adapter) at 1600x900. So in both instances my desktop is 3200x900. I run a VNC server on the laptop and connect to it (via SSH tunnel) from the desktop - when I press the full screen hot key, I get a 1600x900 view of the remote machine on one monitor, and half of my local desktop on the other monitor - the "full screen" only expands to fill one local monitor.
Normally this is exactly what you want when you full screen a web browser, email client, or other application. I'm sure there's some X magic to make it clear what a full screen actually entails, and the vnc client application is just dutifully accepting what it's told. While I would like to keep the normal full screen behavior for regular applications, but when I'm VNCing to another 3200x900 machine, I'd really like full screen to stretch across both local displays. Resizing the window to be "close" isn't quite good enough since I still have local panels at the top and bottom of one display (though I can set them to autohide), plus the VNC client application window border (since it doesn't appear to respect -notitle).
Is there any good way to have X lie to a single application about the "full screen" size? Can I get it to lie to all applications? xrandr --noprimary appears to have no effect.

having trouble setting up a dual monitor from my Dell xps laptop using an HDMI port. It dual boots onto Ubuntu 10.04. The computer has a Nvidia GeForce GT 555M with Optimus graphics card I need to make sure I have not installed the restricted drivers. So I think what is happening right now is that the graphics are shown off the integrated graphics card. This is my output from <lspci | grep VGA>
Code:
00:02.0 VGA compatible controller: Intel Corporation Device 0126 (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 0dcd (rev a1)
The forum recommends to use this program called Bumblebee but I have had some issues with that in the past. Is there somehow I can setup my dual display while staying on Ubuntu 10.04 and not installing Bumblebee? I have researched into setting up dual display walkthroughs before but they all concentrate on nvidia or ATI configurations.

I upgraded to FC10 from FC8 and my Gnome-panel no longer spans both screens in my dual monitor configuration. This worked fine in FC8, and I can't seem to figure out how to make this config work in FC10.
I've tried Xinerama and Twinview, and various configurations in xorg.conf, and cannot seem to make it happen.
How to make both my panels (top and bottom) go across both screens?
