Ubuntu14.04 installs AMD graphics driver dual-screen display complete solution

There are many ways to do it online, but there are few solutions for AMD graphics, so I would like to write a tutorial on AMD graphics today.

First of all, go to this URL to download some things: http://support.amd.com/zh-cn/download/desktop?os=Ubuntu+x86+64, explained that this URL is for the Ubuntu64 bit system, 32-bit users please select the 32-bit file download. Which files are under?

There are three of them:

(1) AMD Catalyst? 14.12 Proprietary Ubuntu 14.04 x86_64 Video Driver for Graphics accelerators about 52MB

(2)AMD Catalyst 14.12 Proprietary Ubuntu 14.04 x86_64 Minimal Video Driver for Graphics accelerators (non-x support) /c7> is probably 61MB.

(3)AMD Catalyst 14.12 Proprietary Ubuntu 14.04 x86_64 Catalyst Control Center

These three files are very important, I believe that readers friends see this article when these files have been updated, everyone subset of attention to download the corresponding file can be.

first we have to install the second file (non-xsupport), which can be installed directly do not need to rely on, downloaded after these are the Deb package, so double-click with a new installation can, then install the first file, Next is the third (this is a graphical management tool, you can set the display resolution in the inside, but I think it is not very useful here, if you can, then directly set the good, open the command is $sudo amdcccle. If not, then look down. )

Okay, I'm sure you can enter the order below.

$xrandr

This is a very important display resolution management tool

When entering this command, we will get the corresponding information of the monitor as follows:

Screen 0:minimum 1366 x 768, maximum 8192 x 8192
LVDS Connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
1366x768 60.0*+
1360x768 60.0
1280x768 60.0
1280x720 60.0
1024x768 60.0
1024x600 60.0
800x600 60.0
800x480 60.0
640x480 60.0
DFP1 disconnected (normal left inverted right x axis y axis)
CRT1 disconnected (normal left inverted right x axis y axis)

To explain, LVDS is your notebook's monitor, DFP1 and CRT1 are external monitors, and when connected to the monitor, look at which of these two connections are used.

The author is CRT1.

Here are a few commands:

In order to increase the resolution you need, you can use (1920*1080 for example)

$CVT 1920 1080

Get the following output:

# 1920x1080 59.96 Hz (CVT 2.07m9) hsync:67.16 kHz; pclk:173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920x1080 2048 2248 2576 1083 1088 1120-hsync +vsync

So, this next modeline is the display resolution mode we're going to add.

Well, we'll have to create this model later, with this command:

$sudo xrandr--newmode "1920x1080_60.00" 173.00 1920x1080 2048 2248 2576 1083 1088 1120-hsync +vsync

And then this resolution is new, and we're going to add it here.

$sudo Xrandr--addmode CRT1 (This is my model, everyone corresponds) "1920x1080_60.00"

OK, add success, to the last step! Apply to this monitor!

$sudo xrandr--output CRT1--mode "1920x1080_60.00"

Find your screen is not duang,duang~ and suddenly become the resolution you want it?

Well, write so much, what's the problem you can leave a message ~
