Hello,
I bought a new graphic card (MSI RX 5500 XT - 8 GB) and I have a problem on Kubuntu 18.04.3, my resolution is blocked in 1024*768 and AMD's drivers are no effects (tested with kernel 4.15.0-47.50).
I don't have problem with Windows 10 1909 (dual-boot / W10 fast boot disabled).
My kernel (now) :
Secure-boot deactivated / in compatibilty mode : CSM/UEFI
After read this post, I tried the latest kernel (5.5.2) but I have an error after GRUB.
On a another forum, dedicated to Ubuntu, this has been tried :
/etc/X11/xorg.conf not exist.
Thanks you for your help and sorry for my english.
