Display brightness can be modified only using command line on TransformerBook Asus T101A


I’ve installed Solus 3.99 with MATE Desktop on an Asus TransformerBook T101A and the Brightness Applet, the Brightness setting, etc … does not work … ( I use Mate desktop on PC with openSuSE, Devuan ASCII, CentOS & FEDORA since years and the brightness settings & modifications works OK… Then it is really an issue ).

I can only change the brightness of the display by using using command line.

Then to set the display brightness to 70%  :

  • I’ve installed xbacklight using the Software Center.
  • I ask for the display name :
  •  ~ $ /usr/bin/xrandr -q | grep " connected"
     DSI-1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 
  • I set the brightness of the display DSI-1 to 70% :
  •  ~ $ /usr/bin/xrandr --output DSI-1 --brightness 0.7 

Not really user friendly…

What can I do to fix this issue.

Best regards

Before having a better solution…

I’ve made 4 Scripts and 4 Launchers on the ( top ) panel  of the Desktop :
Then by simple clicking the respective icons I can dim the display respectively to 30%, 50%, 70% , 100% …


The script :

# Reducing the Brightness of the Display using : xbacklight
# Path /home/solus_invictus/GEPlinux_Solus-Invictus_ProvScripts_/GEPlinux_BRIGHTNESS_30-100.sh
function BrightnessSetting()
  /usr/bin/xrandr --output DSI-1 --brightness $BrightnessLevel 

The Launcher :

  • Icon :  /usr/share/icons/mate/48×48/apps/background.png 
  • Type : Select Application
  • Name : DISPLAY__30-100_
  • Command : /home/solus_invictus/GEPlinux_SolusInvictus_ProvScripts_/GEPlinux_BRIGHTNESS_30-100.sh
  • Comment : Set the display brightness to 30 %

Of course I made only one Launcher and duplicate it for each other setting ( using CTRL + drag & drop ) and just modifying the number in Name, Command, Comment..


Then it is less urgent,
Waiting for your help,
Best regards
