After I couldn't log in AGAIN, I pulled AMD Catalyst from Fedora 20

Once again, I did some updates on my Fedora 20 system. And after happily suspending and resuming the laptop for days, I crashed in the OpenShot video editor and had to do a hard reboot.

Except that I never got to the login screen. Just like the last time this happened, I suspected that the Catalyst driver I downloaded and installed from AMD's .run package was not playing well with the latest kernel from Fedora.

So I did what I did the last time this happened:

I paused GRUB, added a 3 to the bootline to boot into runlevel 3 and then removed Catalyst:

$ sudo aticonfig --uninstall

Then I rebooted the machine:

$ sudo reboot

At reboot, I was running the open Radeon driver again.

As I've said before, especially in kernel 3.13.x with Radeon DPM automatically invoked, performance is great. The system might run 5 to 10 degrees warmer than with Catalyst at idle. With a load, it's pretty much the same. That's what I've learned while watching CPU temperature over the past month or so. Once you start doing things, it's going to get hot.

With the 3.13.x kernel and Radeon DPM, video plays great. Even in full screen (as it should, but I digress).

The only thing that doesn't work? Suspend/resume.

We'll see how long I can take it this time.

Meanwhile, if you have any tips on getting suspend/resume working on somewhat modern AMD video hardware, I'm all ears.
