Switchable/Hybrid Graphics and Linux Mint 14
I decided yesterday to take the plunge and move my laptop (HP dv6t Quad with an Intel i7, 8GB RAM, AMD 6770M and Intel graphics) from dual-booting to Linux only. I had been using Linux Mint 14 as a secondary OS on my desktop for a while and really liked what I saw. So, I grabbed the install disc and booted it up.
As usual, the install went without a hitch. I ran all the updates and then went to go install the proprietary AMD/ATI graphics driver (which is now done via “Software Sources” in the Preferences menu). That’s where everything went to hell. Xorg failed to start after rebooting, leaving me at text-based login. Not that I mind playing on the command-line, but vim hardly meets my needs as an IDE and it’s going to be really hard to debug graphical applications that way. So, I began my search. After piecing sources together, here’s what got me running:
First, we need to add the PPA from xorg-edgers so that we can install the ATI/AMD Catalyst Driver 13.1 without having to build it ourselves. The PPA works with Ubuntu 13.04, 12.10, 12.04, Linux Mint 14 and 13.
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update
Next, we can install the driver itself. While I highly recommend doing this just after running updates (and before breaking Xorg), it still works from the command-line after the broken drivers have already been installed.
sudo apt-get install fglrx
Now, everything I’ve read says that you need to remove the PPA before restarting, but nothing says why (if you know, please comment below).
sudo add-apt-repository --remove ppa:xorg-edgers/ppa sudo apt-get update
Finally, give the system a reboot. Everything should be working smoothly now… at least until the next Xorg update.
