I just bought a MSI Bravo 15 laptop without pre-installed OS and I have installed Manjaro with KDE desktop. This laptop runs on an AMD Ryzen 7 4800H processor and has a Raedon RX 5500M GPU.
During the first minutes after the installation it seemed to be fine but then the desktop started to freeze randomly (I could see the screen but mouse and keyboard would not respond) and it did it so often that it almost became unusable.
I have tried to troubleshoot it without much success but what I have noted so far is that the crashes seem to start once I disconnect from the laptop the battery charger. Also, the battery got drained from 100% to 15% in about 2 hours without running any program at all and also got quite warm in the process
I thought it could be related to the drivers and I installed, fron the AUR, the amdgpu-pro-libgl drivers (which I think are basically the Radeon Software for linux) but the, after shutting down, the computer wont boot anymore.
I don’t mind too much reinstalling the system because I just did some minor configurations but I would love to get some help from you to solve these freezing issues and correctly install whichever driver is necessary.
Thank you very much!
