Download Screen Brightness

[Caterina Haggins]

OniPhone, you can make your screen dimmer or brighter (dimming the screen extends battery life). You can also adjust the screen brightness and color manually or automatically with Dark Mode, True Tone, and Night Shift.

This is something I like to do manually several times a day as I have sensitive eyes! I used to be able to access it quickly via the bottom right hand corner of my screen. With Windows 11, it seems the only way is to go into start menu>settings>system>display>brightness....

Five clicks is fine, I'm not impatient, but that feels like an awful lot of visually navigating around the screen trying to read stuff, exactly at the moment when your the brightness is not working well for your eyes! Surely there is some new shortcut I'm missing?

I had a similar problem with my laptop as fn keys did not work!

I installed brightness-controller-git from AUR and solved that problem.

You can also try the command-line tool brightnessctl from manjaro repo as well.

Thank you for your suggestion. I installed brightnessctl from the official repository and it worked on kernel 6.1.49-1 LTS. After the installation, I simply needed to open up a terminal window and type:

It seems that my problem was the open source nvidia drivers. My manjaro installation is currently running on kernel 6.5.0-1, which is the latest one available at the time of writing this. The only downside to this is the closed source drivers. I prefer going full free and open source.

Apple have asked me to perform a clean install of the OS on a partitioned disk which I refuse to do because, 1) I have read on other forums it doesn't solve the issue. 2), I don't have time or sufficient storage space.

Having that said, I see 11.4 is now available but it won't let me update. It comes up with Download failed. Why is this and is anyone else experiencing the same issue? I have around 12GB free storage. Surely thats enough to update.

In my case, disabling (unchecked) the Display setting High Dynamic Range (automatically adjust the display to show high dynamic range content) brightened to display back to full brightness, but management of brightness range is still not operational.

I think I see this also. The screen looks like it is doing a small flicker every now and then.

If I put a finger over the sensor located at the top center of the screen, near the camera enable/disable switches. The screen gets dimmer, if I remove my finger, the screen gets brighter again.

I am on Ubuntu 24.04, to disable the auto-brightness feature, go to Settings->Power->Power Saving - Automatic Screen Brightness

As the title stats my screen max brightness had been lowered quite a bit and after messing around with power settings, going to the manufactures website to download another graphics driver, using Google and searching through forums I find myself here wondering what to do next.

My biggest success/temporary fix came from downloading and installing the lenovo recommended driver for windows 8.1(Intel Extreme Graphics Driver) which restored my screen it its full brightness for about 10 minutes before crushing my hoped by reverting back into darkness, of course I checked the settings again and removed/reinstalled the driver a few times and got similar results each time so I decided to seek out professional assistance if possible.

Well some of the laptops have brighness settings in bios setup. For instance dell always have brighness settings under video tab. There you can increase and decrease the brighness. Press F2 go to setup and find video and then ac and dc brighness. Good Luck

I was looking for the answer and found the error because mine was doing the same thing.

Go to Power Options and then "display" and then unclick where it says to adjust the brightness right under the brightness bar.

I had similar problems with my sis laptop and after all and all going through all the settings even taking it to a technical specialists of which none of them could still find the problem, so there final suggestions was to change the motherboard

The only thing that worked was to go to Device Manager > Display adapters > and disabling whatever graphics you are using. That will half solve the problem... because you won't be able to adjust the brightness.

I found that Lenovo laptops have a keystroke that instantly zaps your brightness I never remember what is it until I have done it.I restart laptop, then when the 'Lenovo' logo appears, press the +brightness button. For me it brings the brightness right back to normal.

For me, the problem was with the Intel Graphics Power Plan settings, which is located in power options, POWER PLAN, change plan settings, change advanced power settings. the problem was my power plan on battery was set to something other than Maximum Performance. I set it to Maximum Performance on both options and all powerplans and now my laptop brightness is fixed to maximum. hope it helps.

Problem is not in settings for brightness its actualy in driver settings for display , Just click right click and pick graphic setting , then u will find monitor looking icon there and u will see setting for colors , and under colors u should have 3 bars with light , contrast and gama ....those are actualy what makes your screen not so bright ;)

I disabled the integrated graphics chip on my computer which dimmed my brightness significantly. I did this in the first place to fix a game rendering and just turned it back on and my brightness was fixed.

Y'all, my screen brightness setting was not working worth a darn and then i noticed that I could also adjust it by using the keys on the bottom of my monitor. That is what worked for me. I almost ripped my hair out and beat the computer into pieces.

Depending on how bright or dark the content of my Photoshop file is, my screen (laptop running Windows 10) will get brighter or darker. This is especially noticeable when I zoom in or out on an image. Never had this before on previous laptops.

I have a new Dell XPS with Windows 10 pro. It is so annoying, I disabled the Windows auto brightness adjust but it keeps changing. For me it is most noticable if I am zoomed out and I just move my mouse outside my workspaces.

This issue with the backlight seems to be persistent. A reboot only temporarily solves it. To be more specific, the brightness is more or less only 2/3rd, no matter if you put the brightness level to 100%. This happens with or without DC dimming enabled.

I also have an error with the screen brightness, explicitly not only with the automatic brightness control, but also with the manual one.

It sometimes happens that if you set the brightness all the way to maximum, the display brightness is just enough when the sun is not shining. When I restart the phone, everything is fine.

Rebooting the phone helped in my case, after the display was so dark that I saw literally nothing outside with max brightness and DC on or off and max. dim off.

will try the light sensor work around next time it happened.

I have just noticed that one of my remotes look a fair bit dimmer than my other remotes. I have checked the settings and the display brightness and keypad brightness settings are the same so I am a little confused??

I have an issue where it takes the remote several seconds after I pick it up to brighten up to where I can see it (even in low light). Is this the same issue? Thanks.

Also, lippavisual, the remote may in fact burn through batteries relatively quickly, but having the rechargeable battery pack pretty much makes this a non-issue. At the end of the day, just place the remote in the charger, and the batteries are fully charged the next morning. I have never run out of battery life on my main TV SR260 and also never even think about it. So I thought this would be a good suggestion for the poster that was burning through AAs.

So I called Control4 and obviously these are out of warranty (18 months old) and I have to charge the customer to replace them? This should be the most reliable component of a Control4 system, outside of the Controllers, and it is a complete disaster.

They were doing some kind of reduced cost replacement for out of warranty 260's. Not sure what the situation is now. Every old 260 I come across is dim. A lot of them have charging/battery issues too. 250's are cheaper, brighter and generally reliable.

Preaching to the choir here. If you think SR-260's are bad, you should try talking to Tesla about the failure rate of the big center touchscreen in Model S cars. This thing literally has a guaranteed 100% failure rate. Has an eMMC chip in it that is guaranteed to fail eventually.

I have installed Ubuntu 16.04 LTS on my laptop and connected it to an external monitor via an HDMI cable. I can easily change the brightness of the laptop screen but that does not affect the brightness of the external monitor. Is there any way to change the brightness of the external monitor as well?

This ddcci driver integrates all ddcci-capable monitors into sysfs, including /sys/class/backlight/.Because i.e. GNOME will use that interface to set the brightness, you can set the brightness without an additional UI, or the terminal.

The brightness controller mentioned before is now version 2. The original simple version is available using the following steps with support for up to 4 monitors. Tested working without issue on Ubuntu 14.04 and 16.04.

To "dim" your external monitor, you can use a program like f.lux, who will remove some colors (blue, mainly) from the GPU output. The result is that the image will look less "aggressive" for your eyes.

But every time I hit the command the brightness of the secondary display reduces for a second and reverts back. Then I found the reason behind it.I was using Redshift and it is periodically overriding all other settings. Simply exit redshift (if you're experiencing the same issue) and try the xrandr command again.
