[Deepin 15.4.1+nvidia driver 375.26] Boot splash screen lost after installing nvidia drivers

Graphics / Linux Linux

Hi,

can anyone at least explain to me, why after installing nvidia drivers from the deepin’s system driver manager (version 375.26) the beautifull deepin boot splash animation is getting subtituted by an ugly, low res animation of three white squares in the middle of grey screen?
Is this a driver issue, system issue, grub2 issue or any combination of those?

Many users over Internet complain about this bug in different ditros - all after installing the proprietary drivers and no one can provide a clear answer what is the cause.

Seems like my grub config is completely ignored - changes made here do nothing.

Any help highly appreciated.
If more info is needed - just ask - I’ll provide.

It’s not a bug, it’s a feature.
That nice animation needs a KMS framebuffer, which nvidia does not provide.

Thx!
Is there any workaround for this or this is simply dead end?

On Linux Mint 18.2 I managed to display the system’s boot animation simply by changing the resolution to 1920x1080 in grub settings although nvidia drivers are also installed. After selecting the system in grub, the LM logo with dots appears for a second, then for a fraction of a second three dots on black screen appear (most probably where the nvidia drivers are being loaded) and then I’m in my login screen.

I don’t understand why settings from Deepin grub config are being totally ignored…
Has it something to do with the fact, that I have two Linux distros? It’s not dual boot though - every system has its own, dedicated SSD. My main grub is on Linux Mint’s drive - from here I can launch 3 systems - mint, deepin and windows. Linux Mint grub is in 1920x1080. Once I launch Deepin I can see that resolution has changed to lower one.
Can I perhaps somehow define in Mint’s grub config how Deepin is launched?
