Wrong resolution during boot

[Bart van Pelt]

When booting the startup screen is in low resolution while before it was in high resolution.

Low resolution during boot is something usually caused by the Nvidia proprietary driver. So I wonder if you might still have some remnants of that installed?

[Daniel van Vugt (vanvugt)]

Actually it looks like just vesafb starting in low resolution:

[ 0.532845] vesafb: mode is 1280x1024x32, linelength=5120, pages=0
[ 0.532846] vesafb: scrolling: redraw
[ 0.532847] vesafb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[ 0.532854] vesafb: framebuffer at 0xf1000000, mapped to 0x (ptrval), using 5120k, total 5120k

which is then later corrected by nouveaufb:

[ 15.346865] fb: switching to nouveaufb from VESA VGA
...
[ 16.853149] nouveau 0000:01:00.0: DRM: allocated 1920x1080 fb: 0x60000, bo 000000004d979e0c

so it sounds like the main issue is that vesafb is used at all during boot.

Can you please try some slightly older kernels and tell us if using those avoids the bug?

After some reading on internet I decided yesterday to install the nvidia diverse in package nvidia-driver-390. This resulted in a non-working graphic display. So I had to restore my installed packages and remove the nvidia-driver-390 package.

When rebooting the initial screen showed the expected graphic resolution instead of a terminal like screen.

I still don't quite understand what happened.
nvidia-settings? or graphic card which has gotten wrong commands from previous installed driver?
