Ubuntu Multimedia :: Command To Enable And Disable A Secondary Monitor Using The Nvidia X Server?
Aug 16, 2010
I need to find out a command to enable and disable a secondary monitor using the Nvidia X Server. I've got a monitor attached to my laptop that I don't use all the time and would like to just have a launcher to switch between "twinview" and "disabled" quickly rather than having to go through the menus. It's physical position is vertically above the primary monitor so I have to put in a custom position every time I enable it.
Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.
I am using Fedora 14. By default Security Enhanced Linux is enabled in Fedora 14. Now is there any way to disable it by command line and then again enable it through command line.
I'm having problems with my Nvidia card. X doesn't work after installation (9.10), only command prompt. I've read the instructions at http://www.psychocats.net/ubuntu/nvidia on how to enable Nvidia drivers, but the instructions are only for GUI, which I don't have. Anyone knows how to enable Nvidia drivers from command line ?
I have a computer that runs debian 6, and i want to make a dual boot system where i can boot either with or without desktop. AS default the server will be booting in console (headless) mode (and act as server) but on some occasions i do want to bootup in desktop.
I know starting GDM (in my case the desktop manager) is just a simple task, but i would like to have 2 options in boot menu: 1 - without desktop default (timeout 5 seconds) 2 - with desktop
Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?
I have just installed ssh-server in my Ubuntu 10.04, and really want to know how to enable/disable it and I also want to be sure if the changes will take effect after the next boot or not, and how to do that?
I installed libvdpau and then I installed the nvidia vdpau software. I was following some steps from another post. When I run XBMC and hit 'O' I can see that the gcpu is still not doing any work (0 - 6%), the two computer cpus are doing all the work. They run at 30%'ish on 720p content and that renders smooth. No prob there. However, the cpus jump up to 50%+ (both cpus) on 1080p content and they can't keep the frame rate steady. It jumps around significantly so of course the movie stutters. No, the network is not the issue. Its completely wired gigabit end to end. Plus I'm running the video from the local hard drive and it doesn't change.
So... the solution is to get VDPAU working and so far I haven't found the right instructions.
I've just finished my new build and installed Ubuntu 10.04 LTS.I have in it an MSI N8400GS D512D3H (NVidia Geforce 8400GS) which I thought would work for Ubuntu. After installing Ubuntu the visual effects are disabled, can't even get "Normal" settings in the Appearance dialogue. Updates have all been installed. Apt has been updated. "Hardware Drivers" screen draws a blank. No proprietary drivers listed at all. First time I've actually used a Graphics Card in an Ubuntu install.
I don't know how to stop this monitor standby thing. When I'm not using the computer, the screensaver will start after a few minutes, what I want. But after a few minutes then, it'll go black. How can I stop this from happening?
I have 2 laptops. Currently I have installed Ubuntu 10.10 on one of them. I have Windoze XP installed on the 2nd laptop. I would like to use my second laptop as my secondary monitor since I hardly use Windoze. Is there a way we can use a laptop as a secondary monitor with Ubuntu installed on the first machine (again a laptop in my case).
i want to disable the su command on a server so that users cant run the su command i removed the comment from the 3 and 5 line in /etc/pam.d/su file but it doesnt seem to work the file is shown below

I've tried to enable the drivers for a Nvidia 8400GS video card on Ubuntu 10.04. I've tried change desktop background > visual effects. It tells me Desktop effects can't be enabled. Sudo jockey-gtk looks and tells me no proprietary drivers are in use by my system. I've tried installing from Nvidia's site and that seems to go okay but doesn't seem to work. I have an internal video card that can't be turned off in BIOS )either ON or AUTO) that might be causing me problems.Lspci:Quote:
Can't enable 3d effects on lucid lynx even if restricted nvidia driver (v195.36.24) is installed and activated. Actually 3D effects were working with compiz etc, but at a given moment -not sure if after the final release of the 10.04 - they stopped working, and now it always fails to enable them.
How can i be able to enable dynamically my second monitor and use Unity at the same time?Summary system:HP Compaq 8710p laptop, Nvidia Quadra 320M, Natty 64bit, with attached 2nd 19" monitorDescription steps taken this far:By default ubuntu ships with the following xorg.conf conform the new minimalist trend:
I use the nvidia-current binary drivers. In this configuration:Unity works Xrandr sees 1 screen (so no configuration of second screen possible)Standard monitor configuration tool in Ubuntu shows 1 screen With [URL]
Code:
disper -d auto -e
my second monitor comes alive. My laptopscreen becomes dark (with moving mouse cursor). Unity / Ubuntu classic (no effects) go into scrambled mode. Mouse is moving, objects are
I just switch from windows to use ubuntu 10.04. I am still learning how to set things in ubuntu. One of the problem is that I can't set my secondary (external) display to my favorite one. I have 22'' screen (max 1680x1050) but I love to set it to 1280x800. I follow instruction from this website https://wiki.ubuntu.com/X/Config/Resolution and my display detail is like this code...
Somehow, I get the new mode in LVDS1 but not in VGA1. How could I add this new mode in VGA1?
I have a dual monitor display with my Ubuntu 10.04 x64 setup and I need to configure Vino to default to the secondary monitor (which is actually screen 0.1). Does anyone know if this is possible?
I am trying to run flash video on my secondary monitor IE my 32" lcd tv which I have hooked up via DVI. my problem is when I bring the window over to the secondary monitor, which I would like to watch whatever on while browsing, and try to put it in full screen it defaults to the primary monitor which is my laptop. can anyone tell me how to change the defualt full screen to the secondary monitor and not the primary?
For X-Mas I got myself a nice little nettop running off an ION motherboard. how to enable HDMI audio output, but got it to work. I've realized that when I'm in XBMC (which is admittedly the only place I watch movies) certain sounds like gunshots will be extremely louder than something like dialog. My friend believes that I should mess around with the channels (to fake the center channel from the left and right) I don't want to threaten Linux, how lightweight I can make it which is critical to an HTPC, but considering XBMC just got a Netflix addon
I'm currently running a three-monitor setup, two of the monitors being connected to an NVIDIA card, and the third being connected to the motherboard's onboard ATI adapter. This works, and it actually works quite well, but after installing the nvidia-current drivers (using the GNOME dialog), I am unable to get any video acceleration going. The GLX module doesn't seem to want to load, and while I'm actually quite impressed with the video performance I'm getting with the open-source drivers, I'd really like to have the OpenGL capability, as it does make things look prettier.
Relevant configs and logs are below.
I should clarify - I don't care about the 3rd monitor on the ATI adapter; I'm only concerned with getting OpenGL working on the two on the NVIDIA - if that's possible, which it may not be...
I have a dual monitor setup with the primary on the left and the secondary on the right. When the login screen comes up after a reboot for instance, the login options such as user selection are on the secondary (right) monitor. How can I change this?
Every time I open an app or window in Kubuntu 10.10, they open up on the secondary monitor. I would like them to open up on the main screen because I don't always want to use my second screen. Is there a setting I'm missing?
I installed Ubuntu 10.04 on my sister's laptop (it's a Packard Bell; not sure about the model, but I could check); it has two graphics cards: the primary is an ATI Technologies Inc Mobility Radeon HD 3650, and the second one is an Intel Corporation Mobile 4 Series. After installation, installed the ATI driver through the restricted devices manager (xorg-driver-fglrx package, I think), and after a couple of reboots, the screen simply went black after boot and I couldn't do anything (I couldn't even switch to a virtual console, and booting on recovery mode was the same). So I booted with the ubuntu live flash drive from which I installed it, and deleted the xorg.conf file, and now I have a GUI, but it uses only the Intel card. I would like to use the ATI card if possible, but the problem is, if I use a xorg.conf file set up to use the fglrx driver, then I have a black screen, and if I use no xorg.conf file, it automatically switches to the Intel card. I also looked in the BIOS for an option to disable the Intel graphics card, but it doesn't have it (it's a very simple BIOS). So, since there seems to be a conflict between both cards, is there a way to tell xorg to ignore one graphics card? (the Intel one, in this case?).
P.S.: Here I attach two Xorg logs: Xorg.0.log is the last one (without using a xorg.conf file, and using the Intel card), and the Xorg.1.log file is the one of my previous attempts at using the ATI card.
I forgot, here is the outpput of lspci:

I have an NVIDIA 9800 GTX. I have 2 DELL monitors connect to this card, one is a 24" and the other is 21".
I am unable to use Xinerama mode with Unity, because for some reason after logging in, I get no desktop interface, only background wallpaper, and I have to force reboot.
How can I setup dual monitors in Ubuntu using Unity properly? Note that I do NOT want to use TwinView, since this results in dead space around the smaller monitor.
