Hi, i am very new to fedora. it just works for now. But every restart does not remember previous level of brightness. Not a big deal may be i just wanted to share, thank you.
Can you share the your system specs. It might be related to the GPU drivers.
i have only fedora os on my about ten years old laptop. it is optimus laptop but i do not use nvidia, terrible screen tearing. so i did not install nvidia driver just enabled rpmfusion repo and installed broadcom wireless driver. other than that os is very responsive.
i have reinstalled fedora a few times and somehow the problem disappeared. upcoming updates should have fixed the issue.
what is the output of this command .
@youssefmsourani, problem showed up again.
output is : intel_backlight nv_backlight
There should be a systemd service running to load/save backlight .
Service name is systemd-backlight@ + backlight + : + VGA_BACKLIGHT + .service ,something like that .
systemctl status systemd-backlight@backlight:intel_backlight.service
systemctl status systemd-backlight@backlight:nv_backlight.service
thank you for your reply. i edited the grub, at the GRUB_CMDLINE_LINUX line add acpi_backlight=vendor and update the grub. so far it works.
