Re: [SOLVED] Awful refresh rate with nvidia card

MODULES=(nvidia, nvidia_drm, nvidia_uvm, nvidia_modeset)

No comma, the entries are blank separated.

==> ERROR: Unable to write to /boot/initramfs-linux.img

You do understand that this is a problem and you'll have to run mkinitcpio as root?
Also make sure that if you've a separate boot partition, that is mounted before running mkinitcpio.

Edit: the journal has no errors reg. the kernel module, so early KMS should™ do.

ok progress has been made! ran mkinitcpio -P as root, and it ran correctly, I rebooted, and now screen resolution is correct, and compositor seems to be working well.

I'm a little late in this but I noticed you never confirmed if you did a grub-mkconfig so the new kernel parameter actually takes hold (none of the your posts mentioned using the other option given earlier of using the conf file in /etc/modprobe.d. Given there's still some issues with the scrolling, are you sure nvidia-drm is actually running with early KMS?  I'm having my doubts, humor me please and run your sudo grub-mkconfg -o /boot/grub/grub.cfg then reboot and check once more?  This little detail is just bothering me and I have a feeling...

I think you identified the problem. when I run grub-mkconfig, it tells me that the parameter that I set is unknown.

[edit] parameter I set is nvidia-drm.modeset=1

here is the grub.cfg

I am struggling to find what I should put in there for grub to understand it. Documentation is not very clear.

Re: [SOLVED] Awful refresh rate with nvidia card

Did you try this yet?

GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1"

GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1"

After doing this and rebooting, my computer is now stuck on a blank screen with a flashing white line. Even after changing it back it is still doing the same thing. I can use Ctrl+alt+F3 to login to terminal, but startx will not work. It says

 (EE) Fatal server error: (EE) no screens found

Xinit:giving up
Xinit: connection refused
Xinit: server error

Re: [SOLVED] Awful refresh rate with nvidia card

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"
GRUB_CMDLINE_LINUX=""

Edit: if you keep having issues it might be beneficial to remove "quiet splash" so you can see what's going on.

Post an updated xorg log (though I don't see how the parameter would have left you w/ a non-starting X11 server) and yes: w/ "output" I meant "monitor".

cat ~/.local/share/xorg/Xorg.0.log | curl -F 'f:1=<-' ix.io

You can only sync to one and if that't the wrong™ one you'll experience tearing (because you're aligning to the wrong output) and stutter (if you're also syncing to the wrong output)

grep -A8 GL_SYNC /usr/share/doc/nvidia/README

I am struggling to find what I should put in there for grub to understand it. Documentation is not very clear.

If the emergency shell won't work for letting you do the following then just boot the Arch Install USB, mount your partitions (in the right order, root THEN /boot), arch-chroot into it:

The nvidia-drm.modeset=1 should be in the first (and should be only) GRUB_CMD_LINE line you have, right after quiet and splash in the GRUB_CMD_LINE, not in a line on its own (it's an additional kernel parameter along with the quiet and splash you already have above it, put it after those but still within the quotes". Delete the extra GRUB_CMD_LINE as well. Save the file then do the step we missed, grub-mkconfig -o /boot/grub/grub.cfg
Exit the chroot, hit sync and enter just for funsies,  unmount everything in /mnt (umount -a /mnt) then reboot and you should be booting to your normal Arch WITH nvidia-drm modesetting working and no more fussy boot problems.

The big take away at the moment is that anytime you change anything in your grub the changes won't take effect unless you do the grub-makconfig line. Otherwise you're still booting off the old config, which in this case was broken twice in a row.
