[SOLVED] GRUB - Incorrect screen resolution after installing a new graphics card

[lcs_europe]

Good evening to everybody

I installed a new graphics card. Since then, the screen resolution at GRUB is no longer correct.

Soft- und Hardware

• OS: Ubuntu 19.10 (5.3.0-42-generic #32-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux). The graphics drivers for the card installed: sudo apt install nvidia-driver-435
• PC: Gigabyte GA-H110M-DS2 (rev. 1.0), Intel Core i7-7700 (3.6 GHz), 32 GB RAM, Palit GeForce 1050 Ti KalmX
• MONITOR: Apple StudioDisplay 27"

I made the following adjustments to the GRUB configuration:

• GRUB_GFXMODE="2560x1440x24"
• GRUB_GFXPAYLOAD_LINUX="2560x1440x24"
• sudo grub-mkconfig -o /boot/grub/grub.cfg and sudo update-grub

I added FRAMEBUFFER=y to the /etc/initramfs-tools/conf.d/splash and did sudo update-initramfs -u.

The splash screen (plymouth) is also displayed in the wrong screen resolution.

Who has a tip on how I can solve the "problems"?

Thank you in advance for your appreciated help and stay healthy, Laszlo

Hi there. Problem solved. I have choose the wrong resolution in the grub.cfg. I replaced the font and size in the GRUB-Theme too.

Thanks for an attempt at marking the thread solved. Better though to use Thread Tools.
