Need help in solving grub2 boot menu video resolution

English Install/Boot/Login
#1

Hi,
I connected the desktop pc with tumbleweed on a 65" 4k samsung tv, the video resolution is fine,
meaning it worked nicely after I login to xfce with the resolution of 3840x2160.

My problem is the grub boot menu that default always to 1024x768
that make the tumbleweed logo’s shape becomes oblong rather than a perfect circle.
The videoinfo is only limited to 3 options like so:

800x600x32
1024x768x32
1280x1024x32

Framebuffer info:

# hwinfo --framebuffer

Is there a way to correct that said boot resolution problem.
Is there a way to trick the grub2 to recognize a higher resolution like 1920x1080 at least
even though that resolution is not listed?

This desktop pc is using the latest tumbleweed snapshot with xfce
The graphics card is an old nvidia geforce gtx 650 ti and using
the hardway driver.

Many thanks in advance.

I am not sure it helps, but once I had a system that di dnotuse the correct screen resolution with GRUB.
I used YaST > System > Boot Loader. The tab Kernelparameters. There there is an item Graphical concole, which is checked and the resolution is below it. The resolution I need was not in the pull down list, but I could enter what I need in the field.

It worked.

Here is a nice tutorial.

All of my machines listed below are configured with “yast2 bootloader > Kernel Parameters > Graphical console > Console resolution > Autodetect by grub2”.

On two most common platforms - PC BIOS and UEFI - grub is using firmware services for video output, so it can only select video mode offered by the firmware.

Thanks, that’s what I do every time even way way back when I started using opensuse.

Thanks, I dig somewhere a bit and yes I have to leave with what I have right now, anyway it’s only for a second that the menu will show up.

It’s a shame for this monitor, my other two monitors with tumbleweed it has a 1920x1080 and works great.

Thanks to all for your replies.

If “auto” doesn’t work properly input the desired value. See e.g. https://www.suse.com/support/kb/doc/?id=000018747

Hi,
Thanks. I already did those things even manually doing the changes in/etc/default/grub before I started this thread.
I also did a custom edid in the /usr/lib/firmware to load for the KMS and I saw it loaded after.

Here is the part of the lsinitrd

There’s a work around in this old thread,
https://forums.opensuse.org/showthread.php/539590-plymouth-splash-screen-shows-vendor-logo-at-incorrect-aspect-ratio-(EFI-boot)
but the problem is, my desktop advance bios option is lock and there’s no way to do the solution in that thread.
