Actually I've solved it - the proprietary driver was installed. What was screwing it up was that I had a second monitor of a different resolution plugged into an hdmi port on the same card. I disconnected the second monitor, rebooted and got a proper display. Reconnected the second monitor and let Ubuntu detect it normally and all is now well

You need to install a proprietary Nvidia driver. The best solution for this card is to do it this way. Run in terminal: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-346 sudo add-apt-repository -r ppa:xorg-edgers/ppa Then reboot.

When your VM is shut down, change the available video memory to something higher. (I use 128 MB - the max allowed)

I've had a similar issue with Bodhi Linux. Something in the installer for vboxedition fails. You can temporarily work around the problem but running vboxuser If that corrects the issue, then you need to set the system to run vboxuser on start up. You can do this by adding the command to the /etc/rc.local file.

I ran into the same problem, and these steps fixed it: 1) On the host, use the latest version of VirtualBox from virtualbox.org. (I used 4.3.26). 2) On the guest (Ubuntu 14.04.2), run sudo apt-get install linux-headers-generic 3) On the guest, do not use the Ubuntu repositories to install the guest additions. Instead, press Host+D to use the guest ...

I fixed my issue! After trying the commands you suggested to me (thanks by the way) I tried the command sudo nvidia-xconfig which backed up the existing xorg and created a new one, and I used startx to boot back up and it worked fine (albeit at 640x480) Thanks again

I know this tread is a little old, but I just ran into this problem myself and solved it. In the install folder that wine uses to run the game, there is a DOSBOX.CONF file (mine read dosboxDK.conf, where DK was the initials of the game). If you edit this as you would the normal dosbox.conf you will get the results you want.

turns out the permissions fault came from my ~/.config/ folder, the location of my monitors.xml file. By default it was 700, once I changed it to 755, the symbolic link (and my correct login screen rotation) worked.

Alright, i figured it out myself. Using the Monitor Asset Manager I could determine a functioning ModeLine for that Monitor, which is: "2560x1440@60" 241,500 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync

You could install arandr. Use arandr to set up your screen. Then save the screen configuration to a script. Create a new Application Autostart item and copy the command from the script there or you could set the script to run at startup.

If you see the purple screen on startup (if not press, Esc before Ubuntu starts): Select Advanced Options. Select Recovery Mode. Select FailsafeX. Click yes until you get back to continue with normal startup. Your PC will hopefully start now. Then: Select Programs and find Software and Updates. Click Additional Drivers. In the Additional Drivers ...

In case somebody finds this via Google: The 6900 series does not allow for HDMI in a resolution above 1080p. It worked on my Windows machine because the drivers I used there were old and buggy. The drivers I used on Linux were not so it didn't allow me to go above 1080p (as it was supposed to).

Install proprietary AMD drivers. System settings -> Software & Updates -> Additional drivers.

Skype is a Qt program, and needs to be configured separately. You cannot change the DPI setting for it, but at least you can change font size. Install qt4 and run qtconfig-qt4 to do it. Source: archwiki

Windows 7, VBox 4.3.12 r93733 (current version does not play nice with Avast) I spent hours trying to get this working full screen, these 3 steps worked, thank you! System settings menu item not working, so I had to sudo apt-get install unity-control-center all working now.

I am running 14.04LTS on an ASUS M51AC with an Nvidia 625GT OEM. I found that in addition to the accepted answer, I needed to also add the line: GRUB_GFXPAYLOAD="keep" to /etc/default/grub.

@Takkat is spot-on. The problem is the version of X Server on the GUEST in relation to what the HOST's version of Virtualbox will support in order to get full-screen. You can get the version of X Server with X -version. Run this on the GUEST to see which version is installed. Of note, there is one - rather than two --. Also, this command outputs to stderr ...

You probably have an hard time using the terminal. Don't worry it's quite simple, just follow those steps: Start the machine Now, on the top menu, go on Devices and click Insert Guest Additions CD image ... In Ubuntu 15.04 you can just run it, it does everything by itself. If it doesn't, follow those steps. Open the terminal from the launcher Write cd ...

I have tried several re-installs since posting the original question and I have been able to get my system running with 3840x2160@60hz. This post is to help others who might have the same problem. One of the things that concerned me about my setup is that I can't make the displayport output the primary monitor on the system if the DVI ports are used. The ...

Looks like you need a custom modeline for your display (Basically a custom "output"). Either that or your drivers aren't working properly... I had this issue with an old monitor and a custom modeline sorted it right away :P You can add the native resolution modeline (1920x1080_60.00?) and then you should be able to switch to it, any other resolutions will ...

Regarding your system font, go to System Settings and check Displays. There is an option called 'Scale for menu and title bars:'. Change the value on the scale given below that to change font size. Regarding websites, I guess it changes based on the browser you use and the website you visit. Check this thread. Hopefully it will solve your problem.

Try sudo apt-get install nvidia-current As that will install nvidia drivers.

Well a got Linux geek in, and I'm glad I did. It took him over an hour to sort it out. Nothing he tried worked easily. He did eventually cure it by loading the corect NVIDIA driver, but it was far from straight forward. Anyway, thanks for trying to help a newb like me. Phil

Not sure if you are using DVI or HDMI to connect (my machine reports both as HDMI in xrandr), but it seems that Intel HD graphics is limited to DVI single-link. As you noted, the highest it will report is 1900x1200@60Hz. As far as I can tell, current Intel HD graphics do not support DVI dual-link. However, it may be possible to enable 2560x1440@30Hz over ...

A major convenience upgrade would be to use a background script, automatically setting the resolution per application, while you can set different resolutions for different (multiple) applications at once. That is exactly what the script below does. An example of a default resolution of 1680x1050: Running gedit, automatically changing to 640x480: ...

You said: sudo cp b43_updated.zip /lib/firmware/b43 and then sudo modprobe -rv b43 and sudo modprobe -v b43 I believe you need to unzip the file first. Please try: cd ~/Desktop unzip b43_updated.zip It extracts into its own folder b43. Continue: sudo cp b43/* /lib/firmware/b43 sudo modprobe -r b43 && sudo modprobe b43 It may take a ...

I solved my problem! First I removed the existing NOUVEAU. With sudo nvidia-xconfig I create a new xorg.conf After that I added the DPI line. Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" Option ...
