I have a problem with Xubuntu Bionic (18.04.3) running on a Dell Precision 7530 with an AMD Radeon Pro WX 4150 video device. I recently installed the AMD GPU Pro driver from this location, specifically the file amdgpu-pro-19.30-934563-ubuntu-18.04.tar.xz.
What's working
- Encryption login screen works
- X works fine on the laptop display
- Dock-connected displays (using the WD19DC dock)
What's NOT working
- HDMI output on the laptop
- Mini-DP output on the laptop
- OpenGL
- Many Qt apps (probably because OpenGL is broken)
Specifically, xrandr reports that it knows about the HDMI and DisplayPort connections on the laptop, but nothing is recognized when attached to those ports.
Also, nothing seems to work within the OpenGL framework. Output of glxinfo:
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
Output of glxgears:
Error: couldn't get an RGB, Double-buffered visual

The last three lines of this indicate a potential problem.
When many Qt applications try to start, a segfault appears in dmesg, presumably because they expect OpenGL to work. Examples of broken apps: Wireshark, QDirStat, etc. Below is an example from when Wireshark tries to start:

The console output of wireshark:

Possible explanations I've explored, but could still be it
- I have competing graphics driver files or packages
- I have a configuration file set incorrectly, somewhere
- Another installed/optional library is affecting the functionality of
amdgpu - Something else
I did not install the Enterprise version of the drivers because they only support Ubuntu 18.04.2 and dkms will not build with the Linux 5 kernel (even the driver released last week).
I have tried two firmware-level configurations: with an without integrated graphics bypass. If bypass is disabled (normal mode), the Intel GPU and the AMD GPU are both able to drive. If discrete graphics bypass is enabled, the Intel GPU is bypassed and only the AMD GPU is enabled. While I have a different set of problems related to switching, the problems on this page affect both configurations.
Everything works fine in Windows 10, so I don't think it's a hardware issue.
