Asus N550JV: Brightness Keys and SD Card Reader Not Working
Bought a refurbished ASUS N550JV laptop a few days ago. Managed to install Fedora 20 on it, after a bit of a headache as a result of Window 8 and UEFI. Now that it's all updated and running, I can't seem to get the SD Card reader or the brightness keys working (fn + f5, fn + f6). I've tried following several readily findable guides online, but none of them seem to work. To date, here's what I've tried:
- In vim I added acpi_osi="" to the end of GRUB_CMDLINE_LINUX= in /etc/default/grub, after which I "compiled it" by executing "sudo grub2-mkconfig -o /boot/grub2/grub.cfg" It looked like this:
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/swap nomodeset rd.lvm.lv=fedora/root vconsole.font=latarcyrheb-sun16 $([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :) nouveau.modeset=0 rd.driver.blacklist=nouveau rhgb quiet acpi_osi="""
Also tried acpi_osi= in the same place (without the "")
Created a file named asus-nb-wmi.conf in /etc/modules-load.d/, the contents of which was simply: asus-nb-wmi
After some searching I haven't found any information regarding getting the SD Card reader working.
I'm not really all that familiar with editing the grub file, and I've only been using Linux for 1 year, meaning that I'm not exactly an advanced user by any stretch of the imagination. Can anyone help me out here?
for brightness there is command line tool available in fedora called xbacklight. This command can be helpful when function keys are not working.
Is there anyway to get xbacklight working together with my function keys? Also, will it display the little HUD overlay that one typically sees when adjusting brightness on a laptop?
I think there is no integration available. Its purely command line tool.
I'm leaving that for the worst-case scenario. I'd really love to just get the screen brightness adjusted via the function keys. It's funny, because other combinations work (Fn + F3, Fn + F4 for instance), just not brightness.
you can try one more thing. If you know how to modify kernel boot line in grub then add to that line "video.use_native_backlight=1" and boot the system and can check if brightness keys works for you.
