Power Manager Brightness Applet where is it
I have Cinnamon 20 installed on my HP all in one and I have a brightness applet available on the panel. The same is true on my Asus netbook with 19.3 Mate
I have Cinnamon installed on the Dell kitchen computer but can't find a brightness applet. Any idea why?

Re: Power Manager Brightness Applet where is it
The applet is the Power Applet (power@cinnamon.org) - how it displays depends on if your device is battery powered or not. If yes it shows as a battery icon, if no it's a brightness icon. Brightness can be controlled from it in either mode.
Check if it's on the panel on your Dell

Re: Power Manager Brightness Applet where is it
Here is the response and I don't see power applet. I've thought about hitting the troubleshoot / restore all settings to default. But I didn't because I'm not sure if that re-sets themes, etc.smurphos wrote: ⤴Wed Aug 05, 2020 3:26 am The applet is the Power Applet (power@cinnamon.org) - how it displays depends on if your device is battery powered or not.

Re: Power Manager Brightness Applet where is it
I did find a brightness and gamma applet that can control monitor brightness. There is a notice that it could crash Cinnamon and remove if that happens. So far so good.

Re: Power Manager Brightness Applet where is it
Cool, if you still want to try adding the official power/brightness applet right click on the panel > Applets navigate to Power Applet and click the add button.

Re: Power Manager Brightness Applet where is it
I removed the gamma applet and added the power applet. I see a battery but no controls for brightness. Is it hiding?

Re: Power Manager Brightness Applet where is it
Mouse wheel whilst scrolling while hovering over the battery icon should change brightness. Clicking the icon should show you a brightness slider.

Sounds like a hardware compatibility issue.
Run this command in a terminal and then toggle the slider - what output do you get?

Re: Power Manager Brightness Applet where is it
Some progress - that should be returning intel-backlight on your hardware.
Try this first.
Open the grub config in a text editor
Replace with
Save the file then run
Reboot
Check output of this command again
Any change in the slider working?

Re: Power Manager Brightness Applet where is it
Not at that computer right now but I did try that one last weekend and no changes in the slider.
I'll try it again later, maybe I incorrectly typed something.
BTW thanks for help in this issue.

Re: Power Manager Brightness Applet where is it
Fair enough - reverse that tweak.
Next one to try is adding a config file
Add the content
If that's no go there are other kernel parameters that you can try
video.use_native_backlight=1
acpi_backlight=video
acpi_backlight=none
acpi_backlight=native
Next one to try is adding a config file
Code: Select all
xed admin:///usr/share/X11/xorg.conf.d/20-intel.conf
Code: Select all
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
video.use_native_backlight=1
acpi_backlight=video

Hm? My X11 doesn't have an 20-intel.conf in it. Plus I kept getting a message that I could not access because the specified location is not mounted.
I guess I could use XED to make that 20-intel.conf file?
I have admin rights and normally just use sudo. Is doing it with suco bad protocol?

It isn't as though I am having problems but it is an interesting issue to try and sort out.
