Full dual-Screen Display solution for installing AMD graphics card driver in Ubuntu 14.04
There are many methods on the Internet, but there are not many solutions for AMD graphics cards, so I want to write a tutorial on AMD graphics cards today.
First, go to this URL to download some software. This URL is for Ubuntu 64-bit systems. For 32-bit users, select 32-bit file downloads. Which files?
There are three:
(1) AMD Catalyst™14.12 Proprietary Ubuntu 14.04 x86_64 Video Driver for Graphics Accelerators is about 52 MB
(2) AMD Catalyst™14.12 Proprietary Ubuntu 14.04 x86_64 Minimal Video Driver for Graphics Accelerators (Non-X Support) is about 61 MB
(3) AMD Catalyst™14.12 Proprietary Ubuntu 14.04 x86_64 Catalyst Control Center
These three files are very important. I believe that when readers see this article, these files have been updated accordingly. You just need to download the corresponding files.
First, we need to install the second file (Non-X Support), which can be directly installed without dependency. After downloading, these are all deb packages, so double-click to install them with a new one, next, install the first file, followed by the third file (this is a graphical management tool, you can set the display resolution in it, but it doesn't work very well here, if you can, you can set it directly. Open the command $ sudo amdcccle. If not, go to the next step .)
Okay. I believe you can run the following command:
$ Xrandroid
This is an important display resolution management tool.
When you enter this command, we will get the following information about the display:
Screen 0: minimum 320x200, current 1366x768, maximum 8192x8192
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 the monitor of your notebook, and DFP1 and CRT1 are external monitors. When you connect the two monitors, You can see which one is connected to the other.
The author is CRT1.
The following describes several commands:
To increase the resolution you need, you can use (1920*1080 as an example)
$ Cvt 1920 1080
The output is as follows:
#1920x1080 59.96Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083-hsync + vsync
The following figure shows the resolution mode of the monitor to be added.
Now, we will create this mode. Run the following command:
$ Sudo xrandroid -- newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083-hsync + vsync
Then the resolution is created successfully. Next we will add it
$ Sudo xrandroid -- addmode CRT1 (this is my model, corresponding to everyone) "1920x1080_60.00"
All right. It's the last step! Apply it to this monitor!
$ Sudo xrandroid -- output CRT1 -- mode "1920x1080_60.00"
I found that your screen is not duang, duang ~ All of a sudden it turned into the resolution you want?
Okay, that's all. If you have any questions, please leave a message below ~
