AMDGPU-PRO on Ubuntu Zesty with vega rx 64

Question asked by tourettesyndrome on Sep 12, 2017

Hi. Please excuse me for my poor English.

 

I am trying to use AMDGPU-PRO 17.30 driver on XUbuntu 17.04.

 

My system is:

  • Sapphire Vega RX 64
  • Desktop
  • XUbuntu 17.04 (kernel version 4.10.0-33, Xorg version 1.19.3)
  • amdgpu-pro-17.30-465504
  • Envision P2273wL with hdmi <-> dvi cable
  • ms7796 ver 1.2 Don't know about bios version
  • intel i7-4790
  • FSP Epsilon 80PLUS 600W
  • 8 GB

(Yes, i know that the graphic card is too powerful for the system, but that is another story)

 

Installation of the driver was correct, but it has no effect. I got only basic 1024x768 resolution, glxgears are not working.

 

It seems that module has not been loaded:

$ lsmod | grep -i amdgpu
$

 

Nothing wrong in X log:

$ grep -B 1 -A 4 amdgpu /var/log/Xorg.0.log
    built-ins
[    92.310] (**) ModulePath set to "/opt/amdgpu-pro/lib/xorg/modules,/usr/lib/xorg/modules"
[    92.310] (II) The server relies on udev to provide the list of input devices.
    If no devices become available, reconfigure udev or disable AutoAddDevices.

[    92.312]     ABI class: X.Org Server Extension, version 10.0
[    92.312] (==) Matched ati as autoconfigured driver 0

 

And here is the error in syslog:

$ grep amdgpu /var/log/syslog | tail -n 2
Sep 13 01:03:26 homecomp kernel: [    0.750455] [drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu kernel modesetting.
Sep 13 01:03:26 homecomp kernel: [   18.175870] [drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu kernel modesetting.

 

I dont know what to do next. Google says that the error can be avoided by disabling splash and nomodeset parameters from kernel cmdline,

but when I tried it I got just black screen instead of system load.

 

Does anyone has expirience of installing vega with the last driver on zesty?
