[SOLVED]My arch can't set the monitor color

I don't know when it started, my arch gets the following error at startup

systemctl status systemd-backlight@backlight:nvidia_0.service
× systemd-backlight@backlight:nvidia_0.service - Load/Save Screen Backlight Brightness of backlight

I've looked at a lot of people's solutions, and it's nvidia that's to blame.
But their version is 535, and my nvidia driver version is the latest 550.76, but I don't know what's going on, it seems that the previous versions of the recent update 550.76 seem to have had this problem
How can I solve this problem

Re: [SOLVED]My arch can't set the monitor color

Is the device actually (still) correct?

ls -lR /sys/class/backlight/

Re: [SOLVED]My arch can't set the monitor color

Is the device actually (still) correct?

ls -lR /sys/class/backlight/

Enter the command you give to get the following information

 ls -lR /sys/class/backlight/  
/sys/class/backlight/:
总计 0
lrwxrwxrwx 1 root root 0  4月24日 20:46 nvidia_0 -> ../../devices/pci0000:00/0000:00:01.1/0000:01:00.0/backlight/nvidia_0

It seems normal

Re: [SOLVED]My arch can't set the monitor color

# /usr/lib/systemd/systemd-backlight load backlight:nvidia_0

will likely fail too.
If it doesn't produce any error messages, you could try to strace it to see where it fails.
nb. that you cannot use sudo w/ strace, you've to do this from a root shell

# strace -f -tt -o /tmp/backlight.strace /usr/lib/systemd/systemd-backlight load backlight:nvidia_0

I didn't find this program on my system

r97945hx# strace -f -tt -o /tmp/backlight.strace /usr/lib/systemd/systemd-backlight load backlight:nvidia_0
zsh: command not found: strace

But this is probably the same problem as https://bbs.archlinux.org/viewtopic.php?id=295130

Yes, I think they're caused by the same problem

leessmin, you posted a couple 'reports' to moderators that I think had been intended to be a 'reply'.  Just in case you are wondering where your posts went

Re: [SOLVED]My arch can't set the monitor color

leessmin，你向版主发布了几份“报告”，我认为这些报告本来是“应该报告”的。以防你想知道你的帖子去了哪里

Thanks for the Pointers. I'll take care of it
