I'm using a lg 20EN33 and Ubuntu 16.04lts didn't recognized this display. Because of that, I can't set the display recommended resolution (1600x900) and I'm stuck in 1024x768.

I tried this: How to change the monitor's refresh rate? and using xrandr I was able to set the proper resolution (1600x900), but now I see little dots around the monitor and it's really annoying.

I don't know how to look up for this trouble.

If I run lspci -vnn | grep -i vga -A 8 I get the following output:

00:02.0 VGA compatible controller [0300]:

  • Did you install graphic drivers? – Danibix May 3 '16 at 13:41
  • I haven't, the Additional drivers option show me "Unknown:Unknown, this device is using an alternative driver." – lcjury May 3 '16 at 13:48
  • Could you add to question the output of this command: lspci -vnn | grep -i vga -A 8? – Danibix May 3 '16 at 13:50
  • @Danibix done :)! – lcjury May 3 '16 at 13:52

Please, take care: there is still no Intel Linux graphic installer for Ubuntu 16.04, but I'm pretty sure this will work also on your PC.

Intel Graphics Driver is a software that help you to install right Intel driver on your Ubuntu PC. This should make your Intel Graphic controller work properly. To install it follow these steps:

  1. Download from here and save it where you want.
  2. Open a terminal pressing Ctrl+Alt+t and change the current terminal working directory to where you downloaded the previous .deb file:

    cd <downloaded_file_location>
  3. Install graphic installer with this command:

    dpkg -i intel-linux-graphics-installer_1.4.0-0intel1_amd64.deb

    If you want more information about dpkg command, type the following command to read the manual:

    man dpkg
  4. Now Launch graphic Intel graphic installer and follow the instructions to install the software.

  5. After driver installation close the program and reboot your system. When it start it should work on recommended resolution.

I hope this could help you.
