Ubuntu :: Compiz With Two Monitors Without TwinView?
Feb 4, 2011
Here is my question:
I recently installed Ubuntu 10.10 (32bit) on an HP compaq nc6400 laptop (internal display is 1280x800, graphics card is an Intel Mobile 945GM/GMS, 943/940GML Express) which I am using in three situations: In my office: external monitor (1280x1024), laptop in docking station with lid closed At home/on travel: as it is, without any external monitor When giving lectures: with projector (1024x786), lid open, same output on projector and internal display As you see, I either want one output device only or both showing the same output. Additionally, I want to run compiz. My problem is that, whenever I (1) connect an external display or (2) when I press the Fn+F4 key to change displays or (3) sometimes even when I open/close the laptop's lid, the system at some point switches to TwinView which seems not to work with compiz on my system. The effect is that compiz is deactivated. When I want to have it back, I have to open the appearance settings and change to extra visual effects again. Unfortunately, that reverts compiz to default settings and I have to adjust my compiz settings again. note that compiz works properly in all three situations I listed above. The problem is "only" that, at some point, it switches to TwinView.
Is there a way to tell X or compiz NEVER TO CHANGE TO TWINVIEW?

Is it possible to run TwinView with more than 2 monitors.When I try, it seems to recognize the 3rd monitor, but will allow allow them to be configured as separate X screens.

I frequently watch movies on my computer, but I have two screens. So having something displayed on the other monitor is annoying.
I currently use this to turn off my monitors:
xset dpms force off
I was wondering if there's any way to turn off monitors independently, without having to physically press a button on the monitor, of course.
A program that tells the other monitor to display nothing but black would suffice, but I'd really prefer not to waste the power.
I also have Nvidia TwinView, so applications like grandr aren't aware of both monitors as being independent.

Im running a dual monitor setup in gnome, with the closed nvidia drivers in twinview mode. most of the times i want to be able to maximize windows to a single monitor (this is the default behavior in 10.04 lucid i believe), but sometimes i want to span a window on both screens. compiz doesn't allow windows to resized past screenborders, and gdevilspie wasn't able to get past this.
After a lot of googling and toying around i came up with the following sollution, i'm posting it here so other people can enjoy it as well (and i'll be able to find it again after my next install).
I made a script to switch between the streched mode and the doublescreen mode to use it, you'll have to stop the autodetection of the outputs in compiz. this option is found in compiz config settings manager under general settings > display settings or though the gconf-editor in /apps/compiz/general/screen0/options/detect_outputs
This script switches between the two modes, but you need to edit the resolutions of your monitors! (i have a double 1280x1024 setup)
Code:
My way of using this:
1. use the script to switch to the span mode
2. start photo/video edit software
3. work
4. close the software
5. use the script to switch back

I know it can be done, I just need to know what the hardware is called. There is a community center in the area and I might have a chance to help out. Due to not enough funding the center was only able to get One PC and five monitors. What I hope to be able to do ( and know its possible ) is get the hardware to make each monitor is own terminal with keyboard and mouse.

I have a GeForce 7200GS graphics card which I've been running in TwinView mode driving 2 IIyama E431S monitors.
I wish to move up to 3 monitors and acquired a USB to VGA adapter but can't get the new monitor to work. I have followed this [URL] and modified the xorg.conf. See below:
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder63) Tue Nov 4 14:07:17 PST 2008
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Mon Nov 3 08:46:46 UTC 2008

I have connected my TV (and my regular screen) to my Ubuntu 9.10. I use TwinView, and that works just fine. I have also installed Moovida (I love that program). And I would like my PC to open Moovida on startup, but I need it to be on the TV screen.

I have no idea what to do to get Twinview to work. I had found a bit of code to paste into the xorg.conf file but after I pasted it in and restarted my computer, but it wouldn't boot up. Whenever I open up the "Monitors" dialog under System>Preferences, it doesn't even see that the second monitor is there! It doesn't matter if I go to the default tool or if I go to nVidia's tool. On the nVidia tool, under X "Server Display Configuration", there is a button "Configure...", when I press it, it asks "How should this display be configured?". The options "Twinview" and "Disabled" are both unselectable and the only one that I can select is "Separate X Screen". It's almost like my computer doesn't know that I have a second monitor plug.
I am running Ubuntu 10.04.
My xorg.conf:
Code:
Section "Device"
Identifier "nVidia Corporation NV34 [GeForce FX 5200]"
Driver "nvidia"
Option "NvAGP" "1"

Recently i've installed 10.10 and have a problem with flickering screen on VGA. I have 64-bit release, ge force 210, nvidia propietary drivers and two monitors:
- AOC_1920*1080_60_DVI
- Philips_1280*1024_75_VGA
- nvidia-current, 260.19.12, 2.6.35-22-generic, x86_64: installed
No matter which monitor is attached to VGA, it flickers randomly every couple of minutes. Sometimes it flickers when i use mouse or keyboard, but sometimes it flickers by itself.

I am having issues maximizing windows/applications on triple monitor setup. I would like to maximize wine, folder explorer, media players, and etc to one screen, instead of across both, which it is currently doing that. Using Separate X [xinerama] + twinview, but I have also tried without xinerama + twinview. When maximizing applications and such, it will only maximizes across both of the monitors in the twinview setup, not the separate X on the left. The separate x has maximizing working to that one screen. I have tried to add xorg tweets, but that's not working, and they are currently in my xorg post below. I had maximizing to one screen working perfectly with dual monitor setup. :S And, I am currently getting an error about " Xlib: extension "RANDR" missing on display ":0.0""
The following Xorgs show the differences, I guess if there is one between maximizing correctly to one screen.
Triple Monitor setup, maximizing across both twinview monitors, not preferred:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings

I have 2 nvidia graphics cards and 3 monitors. One graphicss card is an nvidia 460 and the second one is an nvidia 8400 GS. I'm on Ubuntu lucid 64 bit gnome desktop. I use the nvidia drivers . 2 monitors are connected to the 460 card setup as twinview the last monitor is connected to the 8400 GS set as a separate xscreen.
When I now maximize a window on the 2 monitors which are set as twin view it expands this window gets stretched over both screens. I would like to know how I can set it so that an maximized window get only expands on the current screen in twinview so that I can still move windows from 1 screen to another.

I have a dual monitor setup (Twinview), both monitors are connected to my 1xNvidia MSI NX8600GT card...I've been using a 21.6inch HannsG HG216D (herein referred to as HG216D) monitor as my LEFT monitor, and a Dell 1905fp (herein referred to as 1905fp) as my RIGHT monitor.
I recently got rid of the 19inch 1905fp Dell monitor and moved my HG216D to the RIGHT and now I have a new 23inch DELL S2309W (herein referred to as S2309W) on the left. The new S2309W is connected to my computer via DVI cable and is configured Perfectly at it's native 1920x1080 resolution.
However I can't for the life of me get my HG216D back to it's native 1680x1050. The HG216D is connected via VGA cable that is also routed thru a KVM, I realize this means that this monitor can't/won't be auto-configured. However I should be allowed to set it manually right?...
Code:
Won't let me select 1680x1050 for the HG216D resolution, it will only let me select 1440x900 MAX, there is no option for 1680x1050, (See attached: screenshot)
I've tried to manually edit my /etc/X11/xorg.conf, but after hours on end messing with it, I give UP...
Here is my current xorg.conf:
Code:
I am just not sure what I need to change and how to get the second xorg.conf to play nice via a VGA connection?

I'm running the latest versions of openSUSE and KDE with latest updates installed. I have an nVidia GTS 250 video card with two monitors hooked up. Initially SUSE recognized my second monitor just fine. However, after installing nVidia's own driver (to quiet the loud noise of the card's fan on high) following these instructions, my monitor is only usable after I go into the nVidia X Server Settings (from terminal, as root: "nvidia-settings") and configure it to TwinView.
All is well and good (I can move windows over to monitor 2), except that monitor 2 has no wallpaper (I'm new to KDE, does this mean that monitor has no desktop activity?) and the X Server configuration is not persistent. When I reboot I have to change the X Server settings back to get monitor 2 recognized again.
I tried looking for the X Server configuration file (xorg.conf, right?), in order to replace it with the edited version, but could not find it.

I have 32-bit Windows XP and Centos 5.5 x86_64 on my dual-boot PC, equipped with two generic LCD monitors, Dell (primary) and HP (secondary). I have been running dual screen displays without any problem when running Windows, however no luck getting them to work when I boot up with my newly installed Centos 5.5
In both Gnome and KDE both monitors light up, but secondary monitor (HP) is just a clone of the primary. I have tried setting "Dual Head" in the Display adminitrator but the resulting xorg.conf causes a "Entity is already in use" error and crashes. I have also tried just adding Option "TwinView" "on" but it does nothing. (Are "Dual Head" and "Twin View" exactly the same concept?)
What I am doing wrong? I checked the FAQ and did not find any similar problems being discussed.
Below is my getinfo.sh driver info
== BEGIN uname -rmi ==
2.6.18-194.3.1.el5.centos.plusxen x86_64 x86_64
== END uname -rmi ==
== BEGIN rpm -q centos-release ==

I am currently running ubuntu 10.10
I have a panasonic 50" and a samsung 23" both of which are 1080p displays. I have twinview setup so that the samsung is my main and the panasonic plasma is my secondary. For some reason every time I open a windows of lets say mozilla and it was maximized prior to closing before, it will "jump" (briefly display on the samsung monitor for a split second and then automatically move to the plasma) from my main display to the secondary panasonic plasma. If mozilla was minimized before closing prior and I reopen it will open to the samsung in the state it was in on the prior close (aka minimized), which is fine. Only when it was maximized prior does it "jump" to my secondary display.
How can I correct this issue? I would like to have programs open (and stay) in the display they were launched in whether it is the plasma or the samsung.

I'm running Ubuntu 11.04, using an nVidia graphics card. I have my TV hooked up to my computer and acting as a second monitor, using the Twinview option with the gpu. My monitor is set as the primary display, with the TV as secondary.
The problem I'm having is that when I turn my computer on, the main display is black, and all the load up information is output to the second display. Then, when I get to the log in screen, it is also on the second display.

I'm trying to use an external monitor to watch movies on my linux box (kubuntu maverick) but it results always out of sync. TV-out refresh rate is locked as you can see on the image i've attached right here. This is the output of the nvidia-settings query about the variable RefreshRate:
Code:
Attribute 'RefreshRate' (DeepBlue:0.0; display device: CRT-0): 60.02 Hz.
'RefreshRate' is an integer attribute.
'RefreshRate' is a read-only attribute.
'RefreshRate' is display device specific.

I am posting this to see if anyone else has had an issue with Vmware Workstation 7.1 using unity mode with a Linux Host. The issue I am having is when I try to move a window from my virtual machine in unity mode the screen crashes and then disappears. Everything seems to work while not in unity mode. I have tried various thing like disabling 3d mode in VMware, disabling various KDE effects. I only have these problems with a dual monitor setup, if I switch to a single monitor everything works just fine.

As said here: [URl] I want the sphere deformation, but that needs the PPA apparently (I can't find it anywhere in the default compiz Ubuntu 10.10 ships with.) Compiz starts, but it says it can't load plugin 'decoration.'

I have a Dell inspiron 1525 laptop with a 1280x800 display and an external 1280x1024 monitor. I'm using 9.04 with openbox. I've done a loooot of online reading about how to get a dual monitor setup using xrandr, and I really don't know what I'm missing here. So here's the deal: I want to have my external monitor on the left of the laptop's display, and of course I want each of them to display different parts of the desktop.
First I set up the right resolution to each one of them (I do it using lxrandr). Typing xrandr -q in a terminal, I get the following:

When I plug in my second monitor the 3D cube disappears and I only have the desktop wall thing with a rectangle box from which to select which desktop I want to go to.
I have enabled multi monitor setting in Compiz, tried both one big cube and two separate cube settings but none work.

WHY I can't enable my 3rd and 4th monitor on Ubuntu 10.04? Does it have anything to do with xorg? I can easily do it in Windows! In ubuntu ATI control center will recognize the 3rd monitor but DO NOT let me enable it... the same about the video card! I tried to do it manually changing xorg.conf but it totally ignores it! I found this thread: [URL]Does it have anything to do with XRandR? I managed to get the Crossfire working and enable it after put two identical cards. I've tried adding a 3rd card to even try a 4th monitor but it will not let me at ALL... WHY THIS?? I can do it in Windows but I do not want to use Windows! Why do not allow to use more than 2 monitors??? I'm running a clean new installation of Ubuntu 10.04 64bit and I've installed the ubuntu drivers for my video card. I've a double ATI HD 5770 (crossfire) and a third video card in the motherboard (Asus M4A89GTD Pro/USB3).have 4 monitors, 3 in the crossfire and one in the motherboard. I've managed to do it in windows but in linux I can get max of two monitors working...

How do i fullscreen wow across two monitors in ubuntu? I am running ubuntu 10.04 with two 1024x768 lcd monitors running from a Nvidia 9800gt graphics card running in twinview. I ant to maximixe WoW(World of Warcraft)(running under wine) as fullscreen across both screens. The WoW client recognizes a resolution option of 2048x768, but when i apply it, it squeezes it onto one monitor. how to fullscreen across both?
And i have removed the touching sides of the monitor cases so the screens touch directly so it is feasible to play.
also, i am using the latest nvidia drivers

I have one Dell Ultrasharp U3011 (30", 2560x1600) and one Dell Ultrasharp 2007FP (20", 1600x1200)
When the 2007FP is in landscape mode it matches nearly perfectly in height both pixel and physically wise to the U3011.
See my example picture from my Win 7 dual boot below:
Two Monitors? Ridiculous... by mattlach, on Flickr
The only way I was able to get this to work in Ubuntu was to run two separate X desktops and rotate the 2007FP manually in xorg.conf, and then join them by enabling Xinerama.
Two problems with this solution.
1.) Xinerama is deprecated in favor of Xrandr which I have not been able to make do this.
2.) When using Xinerama Compiz/XGL is disabled, making the desktop feel awfully flat.
Is there any way to avoid this? Is there any way to rotate just one of your displays and maintain Compiz/XGL functionality?
This is on the top computer in my signature.

I have an asus p5kpl-cm MB. I plugged in a radeon 9200 pci card. In the bios, I can set up:
pci/igd
igd/pci
igd
etc.
This determines which of the 2 displays (pci card or internal graphics on the MB) is the boot display. That determines which comes up with the bios screen and then once booted into ubuntu (10.04), this is the only adapter/monitor seen. The button detect monitors doesn't do anything.
lspci sees both my internal and pci card graphics. So, I can get either to work just fine (auto detected etc.) just not both at the same time.
I've tried all of the 3 above settings, and even when I set it to just igd, lspci still sees both my adapters. It identifies them correctly, and it works perfectly, detecting the monitor and knows the resolutions for each - just not both at the same time.
Does ubuntu know how to automatically configure more than one display w/o doing something else, or must I do something else to get both going together?
Code:
$ lspci
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10)
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

My graphics card is nvidia geforce 7900 GS. It has two DVI outputs, and I have one monitor plugged into each output. I am running proprietary drivers from nvidia, thus also the `nvidia-settings' tool.
I'm running with the TwinView setting, enabling nice dragging and dropping of windows between the two monitors, but here's the problem:
Only one of my two monitors have the gnome panels at the top and bottom of the screen. I would like the panels to show up on both screens.
how would I go about enabling this?
Bonus Question: Once this is enabled, if possible, would I then somehow also be able to have different virtual desktops be active on each monitor? If so, how?

I'm having trouble setting up dual monitors on my HP Pavilion dv7-1020us laptop, with an Nvidia 9600M GT graphics card, and Ubuntu 9.10. I installed Ubuntu via Wubi, on top of Windows 7. I tried this before on the same laptop when I was using Vista and Wubi, and Ubuntu was able to recognize my Graphics card, and install a proprietary driver. I wasn't able to test dual monitors, though. However, now that I'm using W7 and Ubuntu, it cannot use a dual-monitors correctly. It recognizes the monitor, but it only displays a mirror display of my Laptop monitor, not acting as a separate monitor, like I want it to. I tried messing around with the settings in the display menu, but nothing works. I tried downloading linux drivers for my card from Nvidia's site, but the file is in a .run extension, which I don't know how to install. What should I do to get this working?
