I recently installed Ubuntu on my HP Probook 470 G3

Everything works fine, except the system often freezes, giving messages with amdgpu... so i decided to install AMD's amdgpu-pro driver. Sadly, using that driver, i'm not even able to login anymore. Trying to log in, the screen just turns black and a little later the login screen comes up again.

I uninstalled the driver using amdgpu-pro-uninstall. But that doesn't solve the problem with the freezing.

Is there anyone running Ubuntu on a HP Probook 470 G3, who got rid of the freezes?

System Information

  • HP Probook 470 G3
  • AMD Radeon R7 M340 (1 or 2 GB DDR3 dedicated, switchable)
  • Ubuntu 16.04

The mentioned amdgpu-pro driver was: amdgpu-pro 16.60 for Ubuntu 16.04

Some additional notes:

  • I think getting the amdgpu-pro driver to work could solve the problem, as the freezes seem to be related to the graphics card power management. The notebook uses a hybrid graphics system and the crashes always seem to occure when the cards switch (for example it always crashes on logout or when you attach / detach a secondary monitor)

  • Using the amdgpu-pro driver and starting the session with startx command instead of using lightdm service directly, i found some errors in Xorg.0.log that match with the errors mentioned in this thread, which sadly wasn't ever answered.

    [    46.106] (EE) AIGLX error: dlopen of /usr/lib/x86_64-linux-gnu/dri/i965_dri.so failed (/usr/lib/x86_64-linux-gnu/dri/i965_dri.so: undefined symbol: is64bitelf)
[    46.106] (EE) AIGLX: reverting to software rendering

[    46.118] (EE) GLX: could not load software renderer

    maybe just somehow adding the missing reference to is64bitelf would solve the problem?

  • Already tried the following drivers: Default Xorg driver delivered with Ubuntu, the mentioned amdgpu-pro driver by AMD and Obiaf's Xorg optimizations (this one resulted in black window borders and context menus)

Any help would be appreciated!

Edit:

Amdgpu-pro do not work with AMD hybrid gpu's. Not yet.
