Remember monitor setup: add it to Startup Applications There are many possible reasons why a monitor setup would not "survive" a reboot. In far most situations, the pragmatic solution is to simply make the setup run automatically on startup (log in actually). How to do that In your situation, DisplayPort-0 obviously represents the left monitor, as we can ...

Try this solution. Use sudo apt-get install nvidia-331 nvidia-settings nvidia-prime and then reboot. You can use application named nvidia x server to configure the display. Unfortunately there is no application named nvidia x server Stefano

When you mirror displays in Ubuntu, the OS behaves like you have one monitor. If you had extended displays before, any files shown on the secondary monitor will be moved to the primary (and only) monitor. If one monitor can't support the other's resolution, Ubuntu will set it to the highest possible common resolution. This can result in stretching or black ...

It appears you are using the noveau driver. I would suggest moving the xorg.conf out of the way, rebooting, and then configuring your desired display using the Display settings panel in System Settings. Once you've got your configuration working as desired, you can copy the ~/.config/monitors.xml file to /etc/gnome-settings-daemon/xrandr/monitors.xml to ...

It turns out that this is not an ubuntu problem as such. I needed an active adapter to translate the DVI signal to the mini-dp signal. Buying this thing worked for me: http://smile.amazon.com/gp/product/B004I6L6DW?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

No, there is no such recommended value for sync rates. There is no way that Xorg know them dynamically only from monitor DDC data. Otherwise, you have to get a common frequency for monitors you have. The fallback frequencies are: (man xorg.conf) HorizSync horizsync-range gives the range(s) of horizontal sync frequencies supported by the ...

Try arandr to change screen definitions. It's in the Ubuntu repository: sudo apt-get install arandr Arandr uses draggable rectangles that represent the physical displays - like display-management-software usually does. Unlike most other software, the displays may overlap, as seen in the screenshot in this thread. You may also try to fiddle around with ...

First, thanks to mchid. I can't say I fixed the problem but the problem has gone away. To close the loop (pun) I'll explain where I ended up. Prior to mchid' guidance to switch users I had installed puppy. After reinstalling Lubuntu (in order to try su) I was able to log in properly without issue. Also, the external monitor became available without any ...

First, login to your guest account and use the su command to switch users in the terminal. For example, if your username is colonelclank you should run: su colonelclank Your username should now appear at the command prompt in the terminal. Next, run the following commands to change to your user's home directory and to fix any file permission issues ...

There seems to be a fundamental problem with synchronization of the Intel and Nvidia video components in (certain?) laptops. See http://askubuntu.com/questions/tagged/tearing for many proposed solution to the issue. Also, the xorg-edgers ppa has an alternative, sudo add-apt-repository ppa:graphics-drivers/ppa which should be the latest drivers.

I wanted to install a second monitor to my desktop via HDMI. In the boot process-the HDMI-port died. I fixed this by disabling the X.Org X server Nouveau display driver and to install and select the NVIDIA binary driver 340.96 in the Ubuntu Software & Updates -> Extra drivers menu. Now I got a dual screen configuration.

So it turns out it's the quotation marks that mess this up. The contents of the file should be: [org.gnome.desktop.interface] text-scaling-factor=0.75 scaling-factor=2

I feel really stupid as its been like 5min since I posted my question. I solved it! I just deleted my xorg.conf file . All my 3d effects and my monitor started working .I'm guessing that that file got added by one of the packages I installed along the way while playing around. I hope that this helps someone in the future .

If you have multiple monitors use this: Turning off your second monitor: (Assuming CRT-0 is your left monitor and CRT-1 is your right monitor) xrandr --output CRT-1 --off Turning on your second monitor: xrandr --output CRT-1 --right-of CRT-0 --auto This way xrandr knows not to duplicate the first screen.

I've got exactly the same problem as you do. Installing the proprietary drivers, like the Internet suggested, didn't help one bit (it caused even more problems). I've found that this problem only occurs when using HDMI + DVI, not when using HDMI + DisplayPort. So, that kinda solves it for me..

I was able to disable the display port by adding video=DP-2:d to the grub boot options. Notice that xrandr was showing DisplayPort-1 even though in reality DP-2 was enabled. Here's how I was able to find out which was the real output device thanks to the ArchLinux wiki: *To get the name and current status of connectors, you can use the following shell ...

What exact model do you have? There where both 1024x576 and 1366x768 models of the HP mini 2140. Might be a stupid question, but I often don't remember which screen I've got on my thinkpad... :)

I have the same laptop and docking station and the same issues as you (3 monitors, but only those plugged into DVI works). It's not a perfect solution, but in my case I've found uninstalling nvidia-settings made things a lot more stable BUT you're stuck with just two displays where plugged into DVI. The laptop screen and the one plugged into VGA does not ...
