[SOLVED] Trying to fix brightness apparently intel/acpi not recognized

Graxin · 2014-03-29 20:40:54

So I've been trying to fix my brightness and xbacklight doesnt work. In sys/class/backlight both my acpi_video0 and intel_backlight arent recognized, if I try to open either one in mousepad it brings up the error:

 Failed to map /sys/class/backlight/acpi_video0/brightness' /sys/class/backlight/acpi_video0/brightness': mmap() failed: No such device.

I have xf86-video-intel as my graphics driver.

If both acpi_video0 and intel_backlight exist, then they are recognized. You are not meant to open the brightness files as text files. You can however, cat their contents:

cat /sys/class/backlight/acpi_video0/brightness

You can else echo values between 0 and the contents of the max_brightness file into the brightness file to try to manually change the brightness.

However, have a read of the Intel Graphics wiki entry. There are a few soutions there that should help.

remember if you're echoing into a file with sudo, you can't do it in exactly the same way as you would do most things

sudo sh -c 'echo "mystring" > /path/to/myfile'

I didn't want toz's comment to get skimmer over. You should always remember to check the wiki, as this is a common issue with new machines.

I keep getting an input/output error when I try to run it.

I used the wiki page to try to fix it and when I created the /etc/X11/xorg.conf.d/20-intel.conf it started giving me errors that no screens were found(EE) and I had to remove it and reinstall the xf86-video-intel to get it to boot and im back at step 1 again. I'll post if I can figure out what I did wrong

What is the make and model of your computer?

What video card(s) do you have and which drivers are they using:

lspci -k | grep -iA2 VGA

This command will print out info about your recognized backlight interfaces:

for interface in /sys/class/backlight/*; do echo -e "\n $interface"; cat $interface/{brightness,max_brightness,actual_brightness}; done

You said that you tried making the /etc/X11/xorg.conf.d/20-intel.conf, but you didn't go into any more detail than that. You need to be specific about the things that you have tried. Too often there are people who come here and say "I followed this page on the wiki..." without any detail whatsoever, and after a while someone finally pries their config from them, something like a typo or some other human error is found. This sucks.

The xorg.conf.d file is not the only fix mentioned there though. There are a number of kernel command line parameters that could also help your situation. Did you try any of those?

Point taken. None of the kernal commands appread to allow me to change my brightess (I assumed), and I tried using xbacklight each time as well as seeing if the folders in /sys/class/backlight/ got rid of the arrow(I think it's for when there's an incorrect pointer) because I thought it wasn't recognizing the backlight for some reason.
I tried using

1. acpi_backlight=vendor
2. acpi_osi=Linux
3. acpi_osi="!Windows 2012"
4. video.use_native_backlight=1 (wiki says it helped people with kernal= 3.13)
5.  I added /etc/X11/xorg.conf.d/20-intel.conf afte another thread in which the person did this on a fresh install like me and it fixed their issue.

At this point I remember there being a different #-intel.conf in there also but when I reset my computer I got the no screens found error and ended up deleting the 20-intel and reinstall the xf86-video-intel which allowed me to boot back to my display manager correctly. The other #-intel.conf is no longer in that folder.

any idea what I missed/skipped/InputtedWrong ?

Do you mean this laptop by any chance?

I'm pretty damn sure that the AMD E2-1800 is an APU (specifically this one), that comes with an AMD Radeon graphics integrated, or am I mistaken?

Further to @toz's above comment, what is the output of

lspci -k | grep -iA2 3D

Further to @toz's above comment, what is the output of
 lspci -k | grep -iA2 3D

doesn't return anything

How is it that you're using an intel graphics driver for a notebook that comes with an AMD Radeon graphics chip? Everything in the specs from the linked product pages indicate one graphic chip (Radeon HD). Can you post back your Xorg.0.log file?

Reznor · 2014-03-30 22:59:44

Full guide c/p, but of course check your hardware as mentioned above. I usually install all drivers and that works every time. I have 2006 Sony Vaio with Radeon 200M and Asus K55N with A8-4500M
Brightness can be only set this way or when proprietary drivers are installed fn keys works out of box.

Open a terminal
Run: ls /sys/class/backlight/*/brightness. Example output would be:

/sys/class/backlight/acpi_video0/brightness

If nothing is found, the kernel does not support brightness control (missing drivers?). Otherwise, you can use the below commands (replace acpi_video0 accordingly):

Get the current brightness level: cat /sys/class/backlight/acpi_video0/brightness
Get the maximum brightness level: cat /sys/class/backlight/acpi_video0/max_brightness
These commands return brightness levels which ranges from zero to max_brightness (see above).

To change the brightness level, you need to write a number to the brightness file. This cannot be done by an editor like gedit. Say you want to change your brightness to 5, you have to run:

echo 5 | sudo tee /sys/class/backlight/acpi_video0/brightness
Alternatively, if you just want to set the brightness level to the highest available:

sudo tee /sys/class/backlight/acpi_video0/brightness < /sys/class/backlight/acpi_video0/max_brightness

I did link the wrong one there was only one 300$ where I bought it and assumed it was the same, its a Asus D550MA-DS01 15.6 inch Intel Celeron N2815 1.86GHz/ 4GB DDR3/ 500GB HDD/ DVD±RW/ USB3.0/ Windows 8 Notebook (Black) (I dug out the box)

At this point I remember there being a different #-intel.conf in there also but when I reset my computer I got the no screens found error and ended up deleting the 20-intel and reinstall the xf86-video-intel which allowed me to boot back to my display manager correctly. The other #-intel.conf is no longer in that folder.

Can you post back the contents of the 20-intel.conf file that you used? It really shouldn't prevent X from starting. If you try it again, it would be interesting to see the Xorg.0.log file from that attempt.

I took the file from the wiki

/etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"

EndSection

Yesterday I reinstall arch and put the file in and today it works, no idea why it wasn't before. Thanks for everyones help.
