Graphics

[shantur]

Hi,

I am trying to get S7150 GPU work in Ubuntu 18.04 and using the Beta 18.30 Linux amdgpu-pro driver I keep getting

[   19.334852] gnome-session-c[1588]: segfault at 18 ip 00007fc2dc5e4b4d sp 00007ffe9a5d27e0 error 4 in libdrm_amdgpu.so.1.0.0[7fc2dc5dd000+d000]

The configuration are

Ubuntu 18.04
 uname -a
Linux vagrant-ProLiant-DL360-Gen9 4.15.0-32-generic #35-Ubuntu SMP Fri Aug 10 17:58:07 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/modprobe.d/amdgpu.conf
options amdgpu virtual_display=0000:08:00.0,1

Any ideas how to make it work.

Thanks

If anyone trying the same, you can get S7150 working in Linux using

Assuming S7150 PCI ID is "08:00.0" in this case. You will need to replace with PCI id for your setup.

1. Amdgpu-pro 18.30 driver

2. /usr/share/X11/xorg.conf.d/00-amdgpu.conf ( remove all other conf files from /usr/share/X11/xorg.conf.d/ )

with

```

Section "Device"

    Identifier "AMD FirePro S7150"

    Driver "amdgpu"

    Option "AccelMethod" "glamor"

    Option "TearFree" "on"

    Option "DRI" "3"

    BusID "PCI:08:00"

EndSection

Section "Files"

ModulePath "/opt/amdgpu-pro/lib/xorg/modules"

ModulePath "/opt/amdgpu/lib/xorg/modules"

ModulePath "/usr/lib/xorg/modules"

EndSection

```

3. /etc/modprobe.d/amdgpu.conf

options amdgpu virtual_display=0000:08:00.0,1

After this you can get X working on the virtual display attached to S7150.

You can use x11vnc to confirm that.
