Hi Lina, This is a relatively new computer. Do you have the non-free AMD firmware isntalled?
The packages you probably want are firmware-misc-nonfree and firmware-linux-nonfree Does the /etc/apt/sources.list file include entries for contrib and non-free? What is the model of your video adapter: if I remember, you have an NVidia card in there? [Nvidia GT730]. Optionally, you can install proprietary Nvidia drivers - https://wiki.debian.org/NvidiaGraphicsDrivers#Version_460.91.03 Hope this helps narrow down the problem. All the very best, as ever, Andy Cater On Fri, Oct 22, 2021 at 10:09:53AM +0200, lina wrote: > Hi Jerome, > > It is not a Mac computer. > > It has only one System, Linux. > > The hardware should be fine as it happens after A BIG UPdating of the > system. > > Howere, below is the hardware info. for your information, > > # lspci > 00:00.0 Host bridge: Advanced Micro Devices, Inc.
