Is this by design? I wanted to set GRUB_TIMEOUT to 10. Thanks!

Yes, the GRUB config is now a static config in Atomic Desktops starting with Fedora 41. See: Silverblue 41 installation is missing `/boot/grub2/grubenv` and `/etc/default/grub` files · Issue #746 · coreos/bootupd · GitHub If you want to edit GRUB specific values, you should now add your config as a…

[image] Mark Rehrauer: set terminal_output=“gfxterm” set terminal=gfxterm set gfxmode=“640x400,1280x1024,1920x1080,auto” set gfxpayload=keep If you add that directly to the main GRUB config, does that work? It’s not super future proof as we might start updating the config in the future but th…

This did not work but I found a clonezilla image from when I was on Silverblue 40 and I was able to mount the boot partition as a loop device and examine the grub.cfg file. From that I extracted part of the script and inserted into the Silverblue 41 grub.cfg file and that worked. I do not think us…

Are you trying to resize grub menu, display manager or desktop display manager? Fractal scaling broke on my labtops on 41. It now defaults to auto which made my GDM and desktop horribly big on a 1920x1080 (16:9) resolution. It auto scaled it to 1.5 which equals 150% scale rate. I reverted it back t…

I am using this the resize the grub menu to the way it was in Silverblue 40.

This is my current /boot/grub2/user.cfg file which gives me a readable grub menu on my workstation with 3840x2400 screen resolutioin. set timeout=10 set gfxmode=1920x1080,1280x800,1024x768,1280x1024 load_video set lang=en_US insmod gettext insmod gfxterm insmod gfxmenu set gfxpayload=keep t…

You can use ``` to surround text that will not be formatted in your replies.

[image] Mark Rehrauer: I really do not understand why there are insmod commands necessary to make it work as the kernel is not involved in displaying the grub menu. Those are GRUB modules. When booting using BIOS, those are distinct files in the /boot partition. When booting via EFI, those ar…

I was not able to use cat. The error said there was no such file. Instead I used nano and created the file and it worked on the next boot. Thanks for this.

Since my earlier post I have removed some of the lines which were not necessary. Here is what I am currently running in user.cfg set timeout=10 set gfxmode=1920x1080,1280x800,1024x768,1280x1024 load_video insmod gfxterm set gfxpayload=keep terminal_input gfxterm terminal_output gfxterm

As far as I know, the migration to a static GRUB config is part of the ComposeFS support, which in turn is related to the transition to Bootable Containers.
