Half screen

Debian x64 is not free xfce. CPU / GPU Amd ryzen 3 2200g. Displayed on the floor of the screen. Question to you how to solve such problems. Where to see what drivers are used? Install / use open / closed drivers.

Code:

inxi -GxxSM

when run in an X session reports:
1-kernel driver
2-in use DDX driver
3-not in use DDX drivers
4-screen resolution
5-other X rendering info
6-kernel
7-machine configuration
8-PCI device ID and more

What does "on the floor of the screen" mean?

Inxi output shows your X server is using a fallback (emergency/recovery mode) DDX driver named fbdev, provided by xserver-xorg-video-fbdev, and the driver your GPU requires, xserver-xorg-video-amdgpu, is not available. So the first thing to try is installing it:

Code:

sudo apt install xserver-xorg-video-amdgpu

and then restarting the X server or rebooting. It might be all you need. Please show output from:

Code:

cat /proc/cmdline

which may indicate a bootloader configuration change could be in order.

xserver-xorg-video-amdgpu is already the newest version (1.2.0-1+b1).

xserver-xorg-video-amdgpu set to manually installed.

The following package was automatically installed and is no longer required:

  libevent-2.0-5

Use 'sudo apt autoremove' to remove it.

Please show us /var/log/Xorg.0.log. It probably has (EE) lines that provide clues to why the amdgpu DDX is not found. Is firmware-amd-graphics installed?

GPU/APU ID 1002:15dd indicates Raven Ridge, which is newer than the 4.9 Stretch kernel. You may need a newer kernel or distro to obtain the required hardware support.
