try to use just your second monitor and check if it is working well. I don't have problem when i extend or duplicate my screen. Only when I use the monitor alone it happens

Mmm not sure why I would do that - I have 3 monitors, 2 driven direct from the PC (one HDMI and one DVI) and the third via the DisplayLink (USB3 to DVI). If I switch off the two main monitors, the third (DL) monitor continues to funciton correctly. If I make it my primary display and reboot, then login (blind, as the login screen doesn't display on my DL monitor), then again the performance is fine. Doesn't really prove anything to be honest unless I start unplugging monitors....(CBA!)

In any case I am happy for now with X11 and have all the functionality I require...we'll see what the new driver is like once its released.

Thx for that... works great... lets wait and see for the official new drivers..

New driver now available and installed - builds/installs just fine under 20.04 and works a treat with both X and Wayland. :-)

Missing Component libdrm
 
Today I want to install the lastest ubuntu driver. But I get the error. Missing Component libdrm. But it is installed. Anyone have the same issue?

You need to make sure both libdrm-dev and dkms are installed: "sudo apt install libdrm-dev dkms"...

Jeins 05-04-2020 01:04 PM

Yep. Both are installed. I uninstall both an let the installer install them, but that don't work too.

Would you like to post your output? Also "lsb_release -a", "uname -a" and "apt search libdrm-dev"

Same here, I was able to install 5.2 using github link given before, but I can't install 5.3, I got same error.
Tried to re-install dkms and libdrm-dev, with no success
