Ok, I did not know inxi. Output is Graphics: Device-1: NVIDIA GF108M [NVS 5400M] vendor: Lenovo driver: nouveau v: kernel bus ID: 01:00.0 chip ID: 10de:0def Display: x11 server: X.Org 1.20.3 driver: modesetting unloaded: fbdev,vesa compositor: kwin_x11 tty: N/A OpenGL: renderer: NVC1 v: 4.3 Mesa 18.3.4 direct render: Yes So nouveau/modesetting is used. The nvidia driver was used but when It stopped supporting my card (and I had to install the nvidia-legacy-39xx driver) something was not done correctly. However I had not many choice at that time it was either install the legacy packages or have a broken install including other packages. What are my options now ? I do not know where to begin looking for documentation on reparaing my install.
