Ubuntu :: Switch Between Single/dual Monitor Mode?
Jan 28, 2011
I recently hooked my television up to my computer as a second monitor so that I can watch videos on it. However, I don't always want to be in dual monitor mode. I've found that running "gksudo nvidia-settings" allows me to switch between the two modes without restarting X if I change some settings around and click "apply".
Is there a way I could setup two scripts to handle this process? The main problem I'm encountering is the fact that I change all the settings through the nvidia-settings graphical interface; therefore, I have no idea what's actually happening behind the scenes, so I don't know how to go about putting the two scripts together (what commands to issue, etc.).

Is there any way to put a dual monitor wallpaper on a single monitor configuration using desktop wall? Using only 1/3 or so per wall. Something that will have the effect like the scrolling wallpaper feature on Android/iPhone.

I am having issues switching between dual monitors and a single monitor.
I have a Dell laptop with an NVIDIA graphics card that I use with a docking station attached to a monitor.
My problem is that if I shutdown without first changing the NVIDIA settings back to the single monitor (the laptop's screen) when I boot with the laptop undocked half the screen is on the monitor that is not attached.
Is there a way to switch between dual and single monitors without using the NVIDIA settings.

Setup:Ubuntu 10.04 recently upgraded from 9.10Dell Precision m63004G RAMCore 2 DuoDual Monitor with laptop=screen0 monitor=screen1external mouse and keyboardIssue:In both 9.10 and 10.04 (I am just now trying to solve the issue) the setup works great, but not flawless.External mouse and keyboard work with no issue.The touchpad mouse on the laptop, however, will not switch from screen1 to screen0. It works fine on either screen and will go from screen0 to screen1, just will not return. One has to hook up an external mouse to get the cursor back onto the laptop screen0.

I am attempting to get a Dual Monitor Display using aticonfig (and/or manual editing my xorg.conf file). My graphics card (a Radeon HD 4350 with latest ati drivers ) has only a single output but I am using a splitter cable to connect it to two monitors.
I am want one monitor to be 1600x1200 and the second monitor to be 800x600.
This is the command I had tried to no avail.
aticonfig -fq --initial --dtop=horizontal,reverse --resolution=0,1600x1200,1280x1024,1024x768 --mode2=800x600
What am I missing? Should I be using this configuration utility? Or should I be trying to manual edit my xorg.config? All the information I have been able to find seems specific to Dual Head Displays.
EDIT: It occurs to me to post my edited xorg.conf file

I have activated dual screen monitors using the Nvidia driver GUI as Sax2 would not correctly configure it. Now at every boot I get the message "undefined video mode 31a, press [enter] for a list of video modes or [space] to continue. After pressing space the system boots to my liking, how can I get rid of the message at every boot up?
I am using Suse 11.2 and KDE4.3.1 My video card is an Nvidia Geforce 7100 GS I thought I was using the Nvidia drivers as I have a GUI from Nvidia in my launch menu if I search "Nvidia" and I have completed the one-click installation. Although when I go into "My Computer" it says driver unknown.

My linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.

When I first installed ubuntu 10.10, the display was for some reason tinted green and shifted a few inches to the right. After experimenting with the resolution preferences, I eventually got it to a large resolution (1280x720 ... or something like that) yet is was quite blurry. I found out that the problem was with my monitor after I switched it to TV mode, then back to PC mode. It became perfectly clear! All I had to do then was adjust the screen positioning by shifting it left a bit.
Even though I have made the resolution I figured out to be default, whenever I turn the PC on after shutting down, it goes back to the "green-and-to-the-side" mode. :/ Ain't really a big problem, until I tried to fiddle with the resolution preferences s'more.
Somehow, I have set it to be twice as wide of the maximum my monitor can display, went back to being green tinted for some reason, and is completely shifted left (yet the right side is still visible) This means that I cannot see what is going on the left side, and cannot adjust the resolution preferences, nor can I click blindly cuz the border is only around my visible side of the screen. Now it is stuck like this.
I've researched many hours and eventually found the terminal command for the resolution preferences. it popped up on the visible side. Although it was to no avail cuz I HAVE TRIED EVERY SETTING AND OPTION and absolutely nothing changed. I assume a system restore would simply revert it back to the previous satisfactory settings, but the thing is I want to FIX it. I am new to this terminal stuff, so I want to learn it and all that. To put it simply, here's what I want:
Learn how to manually adjust resolution without depending on a simple dialog box. Make the satisfactory resolution default and consistent through turning it on and off. Link that could teach me the essential commands, all this googling is stressful. D:

I have a dual monitor setup in Ubuntu, with my main monitor on the right and the monitor I want to extend to on the left monitor, but I can't seem to get it to do this, it always has the 'desktop' on the left monitor and then extends onto what I want to be my main monitor. I have an ATI Radeon 4350 Graphics card.

how i can use VLANs. as i have red on the web, it is possible to have a switch to allocate ports to a single VLAN. thus splitting subnets on a port allocation. since i have a pc running KVM, it is possible to create multiple subnets for DMZ and LAN. thus my question is - is it possible to have a SINGLE cable connection to a switch that carries TWO subnets? so that i can decide how to distribute then on the pc?

How do I get into Single User Mode in 10.04?
The grub menu seems to be gone in 10.04, and the computer boots in 2 seconds. It's great that it boots fast, but there has to be some way to specify boot options?
/etc/default/grub says the timeout is 10, but that doesn't seem to be the case.

This is a repost of my initial problem, I need some one who knows what they are doing more than I too take a look at this command output and give some sort of direction/clue/etc on what I'm doing wrong or missing.
Is my xorg.conf missing some vital line(s) or setting?
My best guess is that i'm missing something to tell the Xserver to use both screens, as the Xorg.0.log does not talk about trying to bring up the intel display; but this is just a hunch.
I'm running kubuntu 9.04 with 2 monitors: on-board intel video and a PCI nvidia display: I am using my nvidia display fine, but still can not get my 2nd display (the intel) working. What the heck am I missing?

just setup suse 11.3 , put on the Nvidia 19.29-22.1 drivers via yast , no kms is set in inetd , nomodeset on grub boot line etc... Even tried installing the driver " the hard way " dual monitors come up, setup xinerama to "Extend" my desktop , and the main monitor ( right side ) is good, visually the left monitor (2ndary) is good.. but whenever I move my mouse over to the left screen the mouse pointer dissapears, flickers along the right hand border of that screen... and if i move the cursor back to the original screen i have to really fight to get it back to the main screen....Copy of my xorg.conf , still very basic...

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.

I've created Oracle Enterprise 5 Virtual machine. It was running fine but not sure what went wrong and now when ever I reboot the machine, it goes to single user mode. If I enter "init 5" command it boots to multi-user X11 mode without any problem.I checked inittab file and default line has id 5. So it looks OK. What else can be wrong?

I am running redhat ES 5 on a dell server and recently, I ran into a snag where I was able to reduce a partition (ext3) but could not run resize2fs (mismatch between physical and logical blocks (i never found a solution to this). In any case I decided to log in a single user mode (appended 'single' at the GRUB loader prompt) and now I am always taken to this single user mode every single time I reboot and can't seem to get out of it. I have tried init 5 (runlevel that the system is set to boot into by default) but that does nothing (no message on the # prompt).Of course, I have 2 problems here:
1) partition issue
2) cannot log out of single user mode.

if I use xset dpms force off, then the monitor sleeps only few seconds (sometimes miliseconds and then goes up again without moving mouse, ... (by itself)But it is no system problem - if the monitor is switched off from GNOME - e.g. after 10 min, then it stays sleeping up to some action (mouse, keyboard, ...).Why do it not work if switched off manually

I'm having difficulty switching from GUI to console mode. I use ctrl-alt-f1 and the screen goes blank and I see a flashing cursor but I'm unable to do anything. I can switch back into GUI mode using ctrl-alt-f7. Also at times I see the word Ubuntu with 4 dots and 2 of them are orange if that's of any use. Like the initial boot loading screen.
I've tried going back to the default display drivers and that hasn't solved it. I'm using a CRT that's connected up to my display card via a VGA > DVI converter. *I've just checked and I can't get into recovery mode either

I'm running debian lenny. Suddenly when I rebooted my system I was unable to login. I type root and the password and it tells me the login is incorrect.If I boot into single user mode, it accepts the password just fine. Looking in the /etc/shadow file, it appears to be fine as well.Running passwd to set a new password sets a new password just fine, i can login to single user mode with the new password, however, I cannot login at a higher runlevel with the password.
If I delete a password in the /etc/shadow file, then try to login as that user, it simply says "Login Incorrect" without even asking for a password.

Upon OS start-up Debian gives a choice, one is just simply start Debian, another line to start Debian, but with brackets (single-user mode). What's this for? And when and why do you need to use this?
