XPS 7590

[mich2k]

Hello
I never managed to make this working unluckyly
Tried on ubuntu 19.10 and now on 20.04 keep having this error
Am I doing something wrong or is not supported?

dell xps 7590 oled-uhd

when I type ./icc-brightness it shows the options*

Did you run sudo make install ?

@mich2k

To run ./icc-brighness standalone (as I understand you're trying), you don't need sudo. But you need to run make in order to compile icc-brightness-gen

Hello, sure I followed the guildeline:

even tried:

but always the same error
When running watch, the error changes:

Hi,
Exact same error for me on XPS 7590

ERROR: device-make-profile-default

I follow the guideline and do make and sudo make install
Kernel 5.3.0-46-generic #38~18.04.1-Ubuntu

And fn+F11 or F12 not working at reboot

[lfglopes]

If you guys updated from 19.10 to 20.04 try to run

./icc-brightness clean and try again

[mich2k]

Already tried
After a clean upgrade from 19 to 20
Everything "as new"

[psyray]

Already tried too. Clean works with no error. But same error when I want to execute icc-brightness.

[mich2k]

I heard that Ubuntu 20.04 fixed the brightness on oled systems
There is no official announcement about this?

[MadhurSahu]

Hello all, I am running openSUSE Tumbleweed with KDE on my XPS 7590.
I was fiddling around with the python code and found that the subprocess.check_output() was not working properly after the recent system update causing the icc-brightness to break.
Turns out reinstalling colord-kde and then running icc-brightness clean solved the issue.
I hope this helps.

Edit: I was getting the same error as @psyray

[mich2k]

#23

This issue here might be the fix and the issue that we are all having
My Dell is set on Italian
Yours?
How can this affect the code..
EDIT:
This actually fixed it for me, but i can not change my whole system lang for a plugin..
hope this helps you all

[agravelot]

Can be helpful (or not)
Just fixed mine by adding i915.enable_dpcd_backlight=1 to kernel boot settings.
Happened today with the latest fedora update.

Can confirm this works!
NOTE: You might wanna change the brightness_step_size=12 to a bigger number for faster response to brightness change. 10000 works good for me!

Trust me or not I already did it, and was not so easy 🤣
And I had to check in the code
Indeed I thought that was not working, then I did an echo $percent and saw that was extremely slow
And I understood the step was WAY too low
Now I fixed it at 1500, I guess I ll increase it

I asked why 12 to the code Dev and he replied me that is a good setup for Lenovo s

Lol I did the same!

Also, you can change
percent=echo "$current_brightness / $max_brightness * 0.9 + 0.1" | bc -l
To
percent=echo "$current_brightness / $max_brightness" | bc -l

This will allow the screen to completely go black when brightness is set to 0 (I use it very often :P)

[mich2k]

How do you use a black screen 😅?

Linux kernel 5.12-rc6 supports OLED display's brightness control: torvalds/linux@2227816

I use Dell XPS 7590 / Ubuntu 20.04
Updating Linux kernel to 5.12-rc6 solved the issue.

Example how to update kernel on Ubuntu 20.04 (at one's own risk)

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12-rc6/amd64/linux-headers-5.12.0-051200rc6_5.12.0-051200rc6.202104042231_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12-rc6/amd64/linux-headers-5.12.0-051200rc6-generic_5.12.0-051200rc6.202104042231_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12-rc6/amd64/linux-image-unsigned-5.12.0-051200rc6-generic_5.12.0-051200rc6.202104042231_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12-rc6/amd64/linux-modules-5.12.0-051200rc6-generic_5.12.0-051200rc6.202104042231_amd64.deb

sudo dpkg -i *.deb

sudo shutdown -r now

[mich2k]

You can also install a Kernel Patch for 5.10, this is also available in AUR named 'oled-linux', just apply this patch and the brightness will kinda work (also the night-mode with redshift)
This is another solution if you dont want to upgrade to 5.12 yet
