I just followed this discussion AMD Radeon R5 Graphics Glitches In Ubuntu 14.04.1 to install driver and restart, then I get only black screen after I choose boot option. How can I fix this situation?

I can enter recovery mode, and use vi command to check my /var/log/dpkg.log file, but there are too many messages like "install...", "remove...", "status...".

I'm not sure if I just use command dpkg --remove \*amd64\* or dpkg --purge \*amd64\* to remove them is safe or not.

  • Ubuntu 14.04
  • Dell Inspiron 14 3459
  • AMD Radeon R5 M315 2GB DDR3

In recovery mode, I choose "root" and enter 

mount -o rw,remount /
apt-get remove fglrx*

It looks like remove failed.

Does it mean that I need to "enable networking"? I've tried to choose that option in recovery mode, but it will show other error messages and can't open terminal successfully.

You need to first remove the driver that you just installed. Many folks forgot to mention fhat you need to create a config file after installing fglrx driver.

First remove the driver by applying

sudo apt-get remove fglrx*

Then reboot the machine. It will be installed xorg driver by default so you may login.

After login you install the driver using AMD's support file that they published for 14.04.

After installing the driver again type this command to set the config file:

sudo amdconfig --initial

If you have dual graphics apply this command

sudo amdconfig --adapter=all --initial

After this reboot the machine and the driver will be installed succesfully.
