@joekamprad I tried this suggestion, gnome always assumes the brightness’ key control, I did not find a way to stop it. Gnome changes the brightness through the keys, but it’s like doing something else. I’m unable to see everything that happens through:
the file / usr / bin / gsd-backlight-helper is a compiled file I can not see if the problem is in it.
is there a way to see the layers is passing by when press brightness key?
Hi!! I’ve been busy lately then unable to test. 2 days ago I tryied:
Ubuntu with Gnome: Same problem
SolusOS with Gnome: Same problem
Manjaro with Gnome: Same problem
Manjaro with XFCE: No problem
P.S. All problem happens only when running gnome under X11 (xorg) as I reported before. And some programs only run in xorg.
As I can see it’s a Gnome bug, but I don’t know why it’s happens in only a few computers, Since I’ve been searching there is only one more forum I found someone with this problem, but its has no answer.
I don’t know what to do now
/usr/lib/gsd-backlight-helper --set-brightness XXX
I did it before,
I think when I press F12 or F11 (keys to adjust the brightness) its doing something else, because when I just run in terminal, it works. but its a compiled file. I don’t know if patch with another version of gsd-backlight-helper would fix, I also not have ideia how to do it.
Should I try another DE or should I try something else?
I was thinking about to use another package to control the brightness. Well while I was reading arch wiki, I read about xbacklight, and I tried to install it, but I already was installed, then I removed and nothing has change…
So what is controlling the brightness when I’m running xorg? Why not to remove it and try to control under xbacklight?
So, how can I know what happens when I press the brigthness key?
I see, the reason of this change is probably because you were using an old kernel with your OS.
Anyway, you could make two launcher one with the command + and one with - in your panel to change the brightness without using the keyboard. I don’t use Gnome so I have no idee how to make it but it’s easy to find.
What is the output of :
Here maybe some answer (BIOS settings) :
And here :
Load Legacy Boot Options was disabled in my BIOS, I tried to enable and has no efect.
About the 2nd link “Set screen brightness” at gnome.org, as I told, I’m able to change it in panel, but I would like to change it using my multimedia keys with no freeze runing xorg.
I’ve been reading backlight wiki page…
What did I tryied:
Change grub GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash X”
X means all thoses:
of course I updated grub every time with:
grub-mkconfig -o /boot/grub/grub.cfg
and restart the PC.
no success Still Freezing/Lagging when use fn multimedia keys
I also installed “xf86-video-intel” for use at “/etc/X11/xorg.conf.d/20-intel.conf” the following settings
Identifier “Intel Graphics”
Option “DRI” “2”
Option “TearFree” “true”
Option “AccelMethod” “sna”
Option “Backlight” “intel_backlight”
even than “/sys/class/backlight” has only a folder called “intel_backlight”
@sushi Thank you for your enforts, but nothing has changed, I also tried to disable environment sensor (control the back light as a smartphone).
I’ve been using Linux for 2 years until January at this same PC, when I choosed change my OS because has no more updates. Well, I was using Apricity OS, everything was working perfectly, but I’ve been using it for around 10 months without update once it has dead. I had no time to change OS before, because my course in University, and now I need some programs that needs an updated version of Linux but I’m getting this problem when running in Xorg (xorg also a requirement) .
Since you told me about the journalctl -f, I was thinking if there’s no way to change the way gnome changes the brightness, if I run the command:
(where XXX a number set by me manually)
/usr/lib/gsd-backlight-helper --set-brightness XXX
it changes the brightness with no freeze. But I dont know how to do it, using the actual value more or less, I mean: currentBrigthness=currentBrigthness + 20, or something like that.
I have knowledge in programming, but I don’t understand so much Linux programming language or it’s structure .
Look at this and try what is said in the answer 3 (create the file /usr/share/X11/xorg.conf.d/20-intel.conf ) :
At this forum in Arch I posted everything I tryied, including it this sugestion. take a look, once I posted here first, when I post in Arch forum, I gave more details all I tryied. But I got no answer, I’ll not use 2 foruns at same time, I’ll try here.
Is acpid installed or not now ?
I would like to see what journalctl -f says when you press the brightness buttons +/- .
After the nex boot or reboot, post the contant of journalctl -b.
In the BIOS do you have any key setting like “Multimedia Key Behaviour”, if yes, try Function Key.
Yes, acpid is installed.
journalctl -f when I press brightness key + and -

In the Bios at "keys Behaviour"I already tried change between “Multimedia Key” and “Function Key” before, did not changed anything about freezing, obviously only was needed me to press fn before use Keys. So I changed back to Multimedia key
