I bought a Lenovo Thinkpad T495 recently. I installed Ubuntu 18 next to Windows 10.
When I connect a second HDMI monitor it is not detected. I have tried to install the drivers from official website but it doesn’t work for me.
I have installed Ubuntu 18.04 with kernel 4.18.0-25-generic.
The processor is AMD Ryzen 5 pro 3500u w/ radeon vega mobile gfx × 8
And the video: Advanced Micro Devices, Inc. [AMD/ATI] Picasso (rev d2)
Also, when I run the xrandr command I get the following error:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
Can anyone recommend a solution to this issue?
