I don't have much experience with these configs, and all the research I was able to do seemed to lead nowhere. The problem is that I'm not able to, for example, use a second monitor - which I'd really appreciate :) Thus, I figured out that trying to run something made for Ubuntu 14.04 would probably not work in my case (in fact I just read a thread of a guy that tried to do that on 18.04 and it didn't go well), and am therefore stuck using nomodeset. But the latest driver distributed by AMD to such graphics card is meant to be used in Ubuntu 14.04, not 20.04. Many answers here in AskUbuntu and other forums seems to suggest that I should download some proprietary drivers to fix this issue. When I try to boot without such option, the computer either restarts while booting, or freezes with this message: kfd kfd: TOPAZ not supported in kfd I'm not able too boot it properly, and can only get it to work whilst using nomodeset in the grub. version: OEM Chassis Versionĭmi.modalias: dmi:bvnINSYDECo rp.:bvr1.I have a Toshiba Satellite L-50B notebook, which has these graphics cards installed: $ lspci | grep -E "VGA|Display"Ġ0:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)Ġ9:00.0 Display controller: Advanced Micro Devices, Inc. asset.tag: Type2 - Board Asset Tagĭmi.board.name: Type2 - Board Product Name1ĭmi.board.vendor: Type2 - Board Vendor Name1ĭmi.chassis.vendor: OEM Chassis ManuFacturerĭmi.chassis.

Problem seemed related to new AMDGPU drivers introduced into new kernels so I tried to disable graphic card by adding radeon.modeset=0 to GRUB_CMDLINE_ LINUX_DEFAULT as suggested here askubuntu.
Running Ubuntu 16.04, system was unstable when first installed it (a lot of random kernel panic). Laptop is Toshiba Satellite S50-B-12R be/fr/discontin ued-products/ satellite- s50-b-12r/
