Linux distributions tend to neglect thorough special key handling, brightness control, touchscreen and pen support,
especially notebook, tablet and convertible users suffer from half-cooked, incorrect or missing implementation.
In many cases system devices are recognized correctly, so let's use what we got and try to mend it for daily use.
download repository from GitHub,
unzip and copy for example to: ~/rotBright
or
copy scripts to current directory
wget https://raw.github.com/qrti/rotBright/master/script/rotate.sh
wget https://raw.github.com/qrti/rotBright/master/script/bright.sh
or
check if git is installed
$ git --version
if git is not installed
$ sudo apt-get install git-all
clone shrink repository to current directory
$ git clone https://github.com/qrti/rotBright.git
figure out your machines touch (and pen) device
$ xinput -list
edit the script
$ nano rotate.sh
if necessary replace preconfigured entries, for correct pen configuration see -> remarks
DEVICE0="pointer:ELAN22A6:00 04F3:22A6" # Asus T102HA touchscreen
DEVICE1="ELAN22A6:00 04F3:22A6 Pen (0)" # pen
DEVICE2="ASUS HID Device ASUS HID Device Touchpad" # touchpad
leave an entry empty to not configure a device
DEVICE0="YOUR_DEVICE:xx xxxx:xxxx" # your touchscreen
DEVICE1=
display rotation possibly sets brightness to maximum, so it has to be restored as well
executing rotate.sh will also call bright.sh and restore brightness if
RESTBRIGHT=true # restore brightness
change directory
$ cd ~/rotBright
make scripts executable once
chmod a+x rotate.sh
chmod a+x bright.sh
execute rotation script
$ ./rotate.sh [+|normal|inverted|left|right|restore]
| + | normal | inverted | left | right | restore | |
|---|---|---|---|---|---|---|
| +90° | 0° | 180° | 90° | 270° | last used | current |
(counter clockwise)
execute brightness script
$ ./bright.sh [-|+|[10-100]|restore]
| - | + | 10-100 | restore | |
|---|---|---|---|---|
| darker | brighter | absolute | last used | current |
see configure to execute rotate.sh in combination with bright.sh
for convenient use you can bind rotation and brightness control to keys,
unfortunately on most laptops the special function key in combination with F1..F12 will not work,
so try to figure out unused combinations with CTRL and/or ALT
example for brightness advance
preferences/keyboard/shortcuts/custom shortcuts/add custom shortcut
name: Bright+
command: /home/USERNAME/rotBright/bright.sh +
key: CTRL-F6
replace USERNAME with your username
to automatically restore last used rotation and brightness at system start do the following
preferences/startup applications/custom command
name: Restore Rotation and Brightness
command: /home/USERNAME/rotBright/rotate.sh restore
startup delay: 15
replace USERNAME with your username
on fast systems startup delay can be reduced
- for correct pen restauration please consider
directly after boot a generic pen device will be listed with xinput
ELAN22A6:00 04F3:22A6 Pen
after first pen use a device instance is added to the list
ELAN22A6:00 04F3:22A6 Pen Pen (0)
use this instance in the script -> configure
- restoring pen orientation after boot and first pen use requires a manual
$ ./rotate.sh restore
- developed under Linux Mint on Asus T102HA Mini Transformer with Visual Studio Code
- not tested on other machines but might work well on various notebooks, tablets and convertibles
