Okay, so everyone is clear with this, to get this to work I followed the following procedure.
#1. Trip host into virtual console BEFORE logging into GDM.
#2. Sudo to root.
#3. Isolate the multi-user.target
#4. Create the file /etc/X11/xorg.conf.d/20-radeon.conf

Code: Select all

Section "Device"
  Identifier "Radeon"
  Driver "radeon"
  Option "AccelMethod" "exa"
  Option "DRI" "3"
  Option "TearFree" "on"
  Option "ColorTiling" "on"
  Option "ColorTiling2D" "on"
EndSection
#5. Isolate the graphical.target
#6. Test, test, test.

Now I did have a problem when I first tried it with the line.

Code: Select all

Option "ColorTiling2D" "on"
My eyesight isn't the best, and the font size was too small for me. I saw it as Option "ColorTiling20" "on", where I had mistaken 20 (numeric twenty) for 2D (two dimensional). Oops... That obviously did NOT work, but live and learn right?

Hopefully me laying this out more step by step is somehow helpful to someone else that is dealing with this issue...

I also encountered this issue with an ATI Radeon card.

Here is my card info:

$ lspci | grep Advanced
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks GL [FirePro V3900]
05:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Turks HDMI Audio [Radeon HD 6500/6600 / 6700M Series]

As you can see this is another model card and has the same issue and fix.

The posted fix has worked for me and seems like it probably affects a number of ATI Radeon card models.

Fix worked for me on Dell 980 with ATI5450 centos7.6
Also KDE plasma (failsafe) booted and worked well enough to find solution.

I wonder if this recent update would help with this issue? From RHBA-2019:0176 - Bug Fix Advisory:
Incorrect interactions between the X server and the xorg-x11-drv-ati driver previously led to a GPU lockup on devices with Radeon GPUs. Consequently, when users attempted to log in to the desktop, the operating system became unresponsive at GDM login screen. With this update, xorg-x11-drv-ati has been upgraded to the latest upstream version. As a result, users are now able to log in as expected under the described circumstances. (BZ#1652530)
The updated RPM is:
xorg-x11-drv-ati-18.1.0-1.el7_6.x86_64.rpm

After a recent update I am now running without the configuration described above.
