I have a little problem not that important but a little annoying.
And I’m asking more with the intent to learn how things are tied together…
I’m using i3wm and I switched to the 5.8 kernel (and previously to 5.7).
But now when the computer boots up I’m ending with a very low login screen resolution (maybe 640x480).
But once I’m logged in, the resolution switch back to the original FHD (1920x1080) resolution of my screen/monitors.
Though, the default Manjaro Wallpaper stays at the low resolution of the login screen and become repeated in a tiled fashion.
So the problem is very limited, fortunately.
I’m not sure which flavor of Manjaro I installed initially a couple of years ago but I remember I tried cinnamon, xfce and i3. But since the default wallpaper says “Manjaro Cinnamon” I guess it was cinnamon.
I’m saying that because in the login screen I have the choice to choose the DM between all of them, so I guess in one point I had to install the others.
And the problem is occurring with everyone of them.
Well, I think that this is expected since it happens at the login screen before the chosen DM starts.
When I select in the grub menu the 5.4 or 5.6 kernel, this problem doesn’t appear.
It appears only with 5.7 and 5.8.
Now I wanted to know, what is the piece of software (grub, X11, xorg, the DM, the kernel, etc.) which is responsible of the resolution before the DM starts?
Where I can fix that issue?
I’m a little confused about how the DM (or WM for i3) and the graphic server (X11 or wayland, not sure which one I have) are tied together.
If you have some lectures about this subject, I’ll be happy to learn more.
Thank you very much.
