You appear to be having a very similar issue to what I had with a Dell Alienware laptop. I posted a solution that worked for me here: Dual monitor setup, why does NVidia 340 Prime only detect one monitor?

Unity Tweak Tool -> Text scaling factor

It seems that due to the unconventional way Dell wired up the 3 display ports, the Nvidia GFX and the on-board Intel GFX in the Alienware M14xR2, you cannot use HDMI and MDP for the external monitors. It is also not possible to disable the Intel GFX in bios as Dell wired up the Nvidia card to pass through the Intel card! Using the HDMI and VGA ports for the ...

Setting a new keyboard shortcut is possible (in Settings -> Keyboard -> Application shortcuts), but finding the right terminal command... xrandr can change the resolution, I know it works if you're using one monitor, it's man page could have more info on what you'd like to do, other answers advise using it...? Here's a clip from it's man page: ...

I have found here about Disper. See link for details. It can be installed from Synaptic or the terminal. The command to cycle between clone, extended, internal and external displays should be like this: disper --cycle-stages='-e : -c : -S : -s' --cycle In that case, it would extend to the right. To cycle between the same options but extend to the ...

You definitely don't have to uninstall Unity. Maybe the simplest solution is install Unity Tweak Tool, and setting the font sizes to suit for you. You can also modify the dconf database with dconf-editor, but that is more tedious and also requires software installation. You can install Unity Tweak Tool using the Software Center, or by the terminal command: ...

Open Configuration (9th icon in your launcher), then Displays, and see if it lets you set a higher resolution.

You mean you can't move your mouse to the proper spot to click on the menu/settings? Try the "windows" button on your keyboard, it's often set to open the menu/dash, and find your "Settings" or "Display" in there (typing them might work), and then change the zoom/scale from there.

Again go to Settings -> Display and reset the zoom level to 1. As for knowing the version of Ubuntu go to Settings -> Details First check the current scaling factor by : Open Terminal and type the following : gsettings get com.ubuntu.user-interface scale-factor This will produce something like this : {'VGA1': 15} or {'HDMI-0': 16} (Note: There may ...

I had the same issue with my ASUS laptop and Dell monitor. What I end up doing is to use xset dpms force off command to make monitor go into power saving mode, instead of turning the monitor off with its power button. I can wake up the screen by pressing a key on keyboard or moving the mouse. With this method to turn off the screen, I never run into the ...

for multi-monitors, before install Nvidia Drive, you should connect one monitor with mainboard's Integrated graphics. Others connect to Discrete graphics. start your computer. You'll view the monitor connected with mainboard is on during login interface, Ctrl+Alt+F2 login into terminal sudo apt-get purge nvidia or sudo apt-get autoremove ...

Would have added a comment, but points wont allow. See this askubuntu comment I gave some time ago. I'm not using same graphics card as you're doing, but installing your drivers using the Additional Drivers settings from Ubuntu is the easiest and most efficient way I found. Ubuntu 14.04 install NVIDIA driver I tried installing using .sh from nvidia, ...

I used the guide in here to do exactly this a few days ago: https://charlesmcruz.wordpress.com/2012/01/22/ubuntu-11-10-automatic-hdmi-toggle-with-audio/ Only had to change the sound profile for it to work perfectly. When I connect an hdmi cable, the display turns off on my laptop and moves to the monitor and the sound changes as well. When I disconnect it, ...

I have this same issue. However, my screen also wont sleep. So any workaround (eg. turning screen on/off) hits this issue. This bug has been raised on LaunchPad: launchpad >> bug 1313539 However, it is currently marked as a duplicate of a more generic bug: launchpad >> bug 1308105 (still open) UPDATE: Jan-17 I just tried with a DVI Dual-Link cable. ...

I think a way to do this in software if you cannot change the brightness in hardware is through xrandr --output LVDS1 --brightness on the command line This will in software make it appear to be more dim or less bright. I found this info on http://manpages.ubuntu.com/manpages/trusty/man1/xrandr.1.html This is just making the screen appear more or less ...

The resolution is not only a factor of your TV (whose details you didn't specify) but also of your graphics card and your module (aka "driver"). So if your TV supports a 1776x1000, but your graphics card (which you didn't specify neither) doesn't, it'll just "scale" to the nearest solution which seems to be 1920*1080. Otherwise, you'll have to go down to ...

xrandr is a difficult way to perform this; I don't recommend it. Go to System Settings > Screen Display. You will see both of your screens. By selecting a screen, you can modify its defaults such as its resolution — and you can turn it off altogether (slide the ON button to OFF). Be sure to locate the Launcher on "All displays" so that you don't end up ...

Ok, this is a little perl script, which sets the display configurations right again after the reboot destroys them. Since I got my local Linux hero to write this for me, I only understand about half of it. So maybe you have to ask a follow up question to get this to work for you. #!/usr/bin/perl # settings our @preferred_outputs = qw(HDMI1 VGA1 LVDS1); ...

The following is a kludge, not a solution: After much stuffing about and scouring the web I continued to hit brickwalls. Some suggested using aticonfig. It had no effect in my case. I was using the xfce desktop. Out of frustration I installed Cinnamon. On booting into Cinnamon the display resolved itself, going full screen with no noticeable overscan or ...

I know this is an old question, but I have exactly the same setup as you, and have been running into the same problem. I figured I'd share this here, since it hasn't been discussed anywhere else. The problem seems to be the proprietary AMD driver in combination with certain older GPUs, rather than any particular X settings. Since these cards only use two ...

In Unity with 14.04LTS nothing of this works. The monitors.xml is well written and has the primary well and positions well defined but when reboots, it ignores the primary and position.

I had the same issues. I connect my Windows 7 PC to my Dell 2709W monitor by DisplayPort. (Nvidia GTX 750) I found solutions here: http://superuser.com/questions/630555/ I disabled the "DDC/CI" in my monitor setting. This solved the problem. I hope this helps.

TV's are notoriously bad monitors (since the ZX80) You should look up how to turn off the TV's over/underscan option in your TV's manual or on it's support site. If it's hanging on a wall, use a digital camera to take a picture from the back-side so you have the exact model number.

Warning: Take your time reading this first sentence: Before typing the following keystroke, remember that Ctrl+Alt+F7 is your friend. This is the keystroke to type to get back to where you are right now. (probably your guest session) OK? Remember? Sure? OK! Now press Ctrl+Alt+F1 to go to TTY1, which is a full screen terminal (and only a terminal: no ...

This also worked for me: gsettings set com.ubuntu.user-interface scale-factor "{'eDP1': 10}" gsettings reset org.gnome.desktop.interface scaling-factor # same as '1.0' gsettings set com.canonical.Unity.Interface text-scale-factor 1.25 gsettings set org.gnome.desktop.interface text-scaling-factor 1.25

Not what you're looking for exactly, but remember you can always access your computer even without any local screen - as long as you have networking configured so that it is ready upon starting. When you install sshd on the computer you can always log in via ssh from a second machine, and reconfigure your X.

Thanks for the help. I created a live DVD and ran the installation from there versus the USB and everything worked perfect. Maybe I had dorked up the way I created the USB.

The two graphics cards will not run in the crossfire operation.The target is a system in which the R9 is passed to a virtual Windows machine (QEMU / KVM - Device Passtrough) The problem is, that i cant activate Display 2 without crossfire.

In order for you to properly use both screens, your cards must be Crossfire compatible. Since both of your cards are, we can now connect the two cards with a ribbon called a CrossfireX Cable. CrossfireX and SLi allow you to connect two or more cards as a single entity on a desktop motherboard. You must turn your PC off, open the shell of the Tower in ...

Okay, that looks like an old answer and things aren't as bad in 14.04 as they once were. Yes, the monitor on the left is usually the primary monitor and it is set this way by default. The unity desktop is actually called the ubuntu-desktop and the reason for this is because unity is actually a compiz plugin so you are actually using a compiz desktop. With ...

Ubuntu doesn't care what the primary monitor is (xconf "use this as my primary display" means nothing apparently), it uses the left/right arrangement of the screens to decide which is primary. Whatever screen is 'left' in screen settings is the primary display. This question has been asked before: Change Primary monitor This question is being asked again: ...

Somehow, the screen settings (xrandr) must have changed to "inverted" while you were trying to fix things. You can fix it by running the command: xrandr --output <screen_name> --rotate normal or, (easyer) by simply loging out and back in :)

Does the guide you're following tell you to run export DISPLAY.... For example, it might say export DISPLAY=:0. If it doesn't, try running that and then echo $DISPLAY.

Looks like a graphic card issue to me. To start off with, type "lspci | grep VGA" and take a note of your Graphic card model, just to make sure it is NVidia GeForce 8400M. You are probably using the xorg open sourced driver right now and high resolution can create problems, as far as I'm aware. To install the unofficial drivers, follow these steps : Press ...
