You could try making this the main video card in BIOS. the Acer monitor that is not detecting is connected to the video card through HDMI cable cord It might make it detectable and hopefully the other monitor connected to the other card will work too. There is no harm in giving it a shot because if nothing loads, then you can always just switch it back to ...

Check if your video card driver is installed correctly, by going to system settings, updates, additional drivers. Run Nvidia settings, when GUI opens check on the Nvidia gui how many monitors are detected, press on detect displays from within the gui and see if second display is detected. If that don't work out, check for driver or Linux software that can ...

May I suggest RedShift? http://jonls.dk/redshift/ It's more maintained than flu.x, it has more options and it works perfectly with Ubuntu 14.10 x64. This is how my configuration file looks like: ; Global settings for redshift [redshift] ; Set the day and night screen temperatures temp-day=4500 temp-night=3500 ; Enable/Disable a smooth transition between ...

I've sent the Asus screen back to Amazon and replaced it with a Samsung one. Problem solved. Clearly I was wrong to think that the screen is just a passive component.

While I am not aware of any solution for this being part of Ubuntu, there is a thrid-party package called disper-indicator that you can use. While it hasn't been updated in a while, it still works fine :-) Download and install this package: ...

Strange, but I found answer first! You use $ xrandr --output $monitorName --rotate $direction where $monitorName can be found in output of $ xrandr and $direction is left for counter-clockwise or right for clockwise. Edit: Using grep, it is possible to write a script like this: #!/bin/bash screen="HDMI1" descr=$(xrandr | grep "$screen") if echo ...

You'll need to use xrandr for that. xrandr -o $orientation Where $orientation is left, right, inverted, or normal. You can select the display you want to rotate with the --display option.

It's very probably a hardware issue: You've probably only got 2 cheap on-board video adapters that can run a max of 1 screen each therefore you can only connect one monitor to one of the display ports for each card... :-( If you need 4 screens, you need to add 2 more cheap video adapters, or one more expensive one (one that can drive 2 monitors) Just to be ...

Intel has a open source driver, you can download with the following link. https://download.01.org/gfx/ubuntu/14.04/main/pool/main/i/intel-linux-graphics-installer/intel-linux-graphics-installer_1.0.7-0intel1_amd64.deb go to the download location and run sudo apt-get install mesa-utils sudo dpkg -i ...

Solved by downloading new nVidia drivers.

Update: Scratch that below, that only works temporarily until I restart the computer again. Then it goes back to not displaying anything upon boot up. Solved the problem via recovery mode and dpkg system repair. Apparently the display module was actually corrupted when changing the settings.

I tried using a display port screen instead of my old vga screen + minidp to vga adapter and this configuration is working.

I did not find a "secret" setting to change the behaviour of the, as it seems, designed behaviour. It looks indeed as if the left screen is assumed to be the "base" screen. It is however very well possible to create a workaround, with essentially the same result. You can create a script that, on the occasion of connecting a second screen, lists all windows. ...

Alternatively, you can install f.lux using a PPA - sudo add-apt-repository ppa:kilian/f.lux sudo apt-get update sudo apt-get install fluxgui The PPA has been updated to work with Ubuntu 14.04 Trusty Tahr.

It could be an actual font that's gone bad, maybe taking a look at that font with something like gnome-font-viewer to check, possibly reisntall the font? But, that's almost exactly what used to happen when I ran earler versions of gnome3 (I think that's still the base for Unity), only it had more letters completely gone and a few other graphic errors here ...

Your results of running the command lspci -nn | grep VGA are: 00:02.0 VGA compatible controller [0300]: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller [8086:a011] (rev 02) Your OS has not detected an NVIDIA card installed on it, as you said in your question, and so you should uncheck the NVIDIA driver (331.113) from ...

You can list the drivers with the command sudo ubuntu-drivers devices Also double confirm nvidia driver with its settings gksudo nvidia-settings Hope this helps!

OK, so go into your bios as I mentioned in my original comments under your post. Find the section labelled Chipset. Then choose System Agent Configuration. Under Initiate Graphic Adapter make sure that PCI Express is selected. Save and Exit from your BIOS so your computer can reboot. Since you are not an experienced computer hardware/firmware/software ...

Have you updated and upgraded after installing? Terminal $ sudo apt-get update && sudo apt-get upgrade $ sudo reboot now

I'm not sure how you're adjusting the brightness, but using xrandr, may yield different results. As in xrandr --output VGA-0 --brightness 1.1 or 0.8 for darker, etc (see xrandr's output for your output name, maybe HDMI-0 or so) [Q showed up in "Unanswered Questions", may help someone with a different brightness option. Probably will never get a reply from ...

Like I was saying, it shouldn't have been doing that in the first place. Install the package linux-image-extra-(yourversionhere) -- it's got the i915 and radeon drivers, which you should need one of. Ya, libreoffice and firefox use quite a few threads, not to mention a fair amount of graphics processing. Now if your system can speak to the gpu in the ...

Sounds like something was wrong the whole time, and now some change has occurred to keep it from eventually "righting" itself. Since your virtual terminals still work, the problem has to do with your desktop. Are you using appropriate video drivers? Which word processor and web browser apps do you use? Which version of Ubuntu? Also, do your hardware ...

There are workarounds: you can, for example, adjust dpi for the most dense screen, and use xrandr to downscale other screens (to keep it crisp). See my answer for a relative question: Is it possible to have two different DPI configurations for two different screens? PS: sorry, the topic is a duplicate, but I do not know how mark it as duplicate - so just ...

It seems people are still struggling trying to work with several monitors and HiDPI displays. A good workaround is described in arch wiki https://wiki.archlinux.org/index.php/HiDPI#External_displays . So, I have: laptop asus ln303ux: 3200x1800, external monitor: 1920x1200 Now I use Ubuntu 14.10 & GNOME Shell 3.12.2 that has pretty usable HiDPI ...

Try using only VGA the first time you configure it, i had many problems with HDMI and ended up using first VGA to configure it.

This worked for me: gsettings set com.ubuntu.user-interface scale-factor "{'eDP1': 10}" There is also this: 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 I've found these in ...

xset dpms force off You can look at man xset for more details. You can also set dpms to standby and suspend, but I think how this works depends on your hardware.
