Brightness Issue on HP - Dv6

This is my first time using linux but im familiar with command prompt, tweaking code etc so trying all those steps wasnt tricky for me, just doesnt seem to play ball with this setup yet.

Can you run "inxi -Fxrz" and post the output here? (surrounded by code tags, the "#" button at the top of the editor). The "z" option will remove ip address, home-directory name, etc.  When you say LL doesn't play well with your laptop, I'm curious what it is. (Others might recognize something.).

Hang in there. I've used a few distros. Linux Lite is up in my top 2-3 (I don't have a #1, they're all best in their own ways.). The mistake you made was probably messing around with the grub. I stay away from that. (If I could ever get my hands on whomever dreamed that up, I would land a series of repetitious blows about his head and shoulders.). If you get into it, it starts to make sense. But... you'd think something so basic wouldn't be so primitive. Sometimes I hit "e" to edit the grub commands (remove "nosplash quiet" and see what's happening). When I edit that, it's like 1990 all over again. 1200baud modem. Press an arrow key, what a second for the cursor to move. WTH? Stuff like that makes me believe we really do live in a simulation, and people outside our dimension are laughing at us.

Have you checked whether Dell has updates for your bios? If so, look at the release notes for every version above yours. If nothing about the brightness keys were affected, it might be better not to update just for the sake of updating. Sometimes you can "brick" your laptop.

Hi there i've ran the command to get  the info you requested please see below:

(i'm going to reformat today though as i tried some steps from the most recent responses and it allowed me to move the brightness bar again but no movement in brightness.

I tried the grub edit of

Code:

GRUB_CMDLINE_LINUX="acpi_backlight=vendor"

then i tried the one for intel cards (which mine appears to have):

Code:

GRUB_CMDLINE_LINUX="acpi_osi= acpi_backlight=intel"

with the results mentioned above (so i'm going to reformat, take a snapshot of OS and then try the last step again, then i may look at patching the kernel which i don't have the faintest clue how to start with that but that will be my next logical step i believe.

Apologies, info you requested here:

That's easy... Go to Lite Tweaks - Kernel Installer / Remover
You can easily install any kernel - you will need to reboot...
I would try in an order, older to newer as the newest kernel will be the default at boot.


You can select kernel at boot - Hit shift at power on - select Advanced Options from GRUB - select desired kernel
*Also should a kernel give undesired results - reboot go back to a working.


Then remove any you no longer need..


Test other functionality too.. Wi-Fi or ?? when testing... I think you mentioned it but a backup is ideal --- Time Shift in LL4.x

Thanks i will look on the link that jerry mentioned about more recent kernels and try your steps to see if a newer kernel will resolve the issue (after i reformat, snapshot, try grub steps... snapshot restore if fails.. then try diff kernels)

Thanks again everyone!
