perkeyrgb\u00a0 <\/a>This *does* work.<\/p>\nI had to install the dependencies:<\/p>\n
$ sudo apt install git python3-venv libhidapi-hidraw0<\/p>\n
Then install:<\/p>\n
$ mkdir -p ~\/src
\n$ git clone https:\/\/github.com\/Askannz\/msi-perkeyrgb.git ~\/src\/msi-perkeyrgb<\/p>\n
$ python3 -m venv ~\/src\/msi-perkeyrgb\/.venv<\/p>\n
$ ~\/src\/msi-perkeyrgb\/.venv\/bin\/pip install ~\/src\/msi-perkeyrgb<\/p>\n
My model was not listed under supported models : “~\/src\/msi-perkeyrgb\/.venv\/bin\/msi-perkeyrgb –list-models”\u00a0 so I chose GE75 at random.<\/p>\n
It worked first time out.<\/p>\n
So, I created a little bash script:<\/p>\n
#!\/bin\/bash<\/p>\n
sudo ~\/src\/msi-perkeyrgb\/.venv\/bin\/msi-perkeyrgb \\
\n–id 1038:1122 \\
\n–model GE75 \\
\n–steady ffffff<\/p>\n
And that worked fine.<\/p>\n
Now, I need to get rid of the need for using sudo:<\/p>\n
$ sudo tee \/etc\/udev\/rules.d\/70-msi-keyboard-rgb.rules > \/dev\/null <<‘EOF’
\nSUBSYSTEM==”hidraw”, KERNEL==”hidraw*”, ATTRS{idVendor}==”1038″, ATTRS{idProduct}==”1122″, TAG+=”uaccess”
\nEOF<\/p>\n
and reload the rules:<\/p>\n
$ sudo udevadm control –reload-rules
\n$ sudo udevadm trigger –subsystem-match=hidraw<\/p>\n
So now the script doesn’t need sudo:<\/p>\n
~\/src\/msi-perkeyrgb\/.venv\/bin\/msi-perkeyrgb \\
\n–id 1038:1122 \\
\n–model GE75 \\
\n–steady 00ff00<\/p>\n
Now that that’s working, I can add it to the KDE menu.<\/p>\n
Install kdialog if necessary:<\/p>\n
$ sudo apt install kdialog<\/p>\n
Make a directory for my utilities:<\/p>\n
$ mkdir -p ~\/.local\/bin<\/p>\n
Now a script that will bring up a color picker and get the numbers:<\/p>\n
cat > ~\/.local\/bin\/keyboard-rgb <<‘EOF’
\n#!\/usr\/bin\/env bash<\/p>\n
RGB=”$HOME\/src\/msi-perkeyrgb\/.venv\/bin\/msi-perkeyrgb”<\/p>\n
if [[ ! -x “$RGB” ]]; then
\nkdialog –error “Cannot find msi-perkeyrgb at $RGB”
\nexit 1
\nfi<\/p>\n
# Open KDE’s graphical color selector
\ncolor=$(kdialog –title “Keyboard RGB” –getcolor) || exit 0<\/p>\n
# Remove leading # from HTML-style color
\ncolor=”${color#\\#}”<\/p>\n
# Validate hexadecimal RGB color
\nif [[ ! “$color” =~ ^[[:xdigit:]]{6}$ ]]; then
\nkdialog –error “Invalid RGB color: $color”
\nexit 1
\nfi<\/p>\n
# Apply color to MSI keyboard
\nif ! output=$(“$RGB” –id 1038:1122 \\
\n–model GE75 \\
\n–steady “$color” 2>&1); then
\nkdialog –error “Unable to set keyboard color: $output”
\nexit 1
\nfi
\nEOF<\/p>\n
chmod +x ~\/.local\/bin\/keyboard-rgb<\/p>\n
Now I\u00a0 can create a Laucher entry so I can choose it from the menu or panel:<\/p>\n
mkdir -p ~\/.local\/share\/applications<\/p>\n
cat > ~\/.local\/share\/applications\/keyboard-rgb.desktop <<EOF
\n[Desktop Entry]
\nType=Application
\nName=Keyboard RGB
\nComment=Set MSI SteelSeries keyboard backlight color
\nExec=$HOME\/.local\/bin\/keyboard-rgb
\nIcon=input-keyboard
\nTerminal=false
\nCategories=Settings;Utility;
\nEOF<\/p>\n
And, finally, add a keyboard shortcut.<\/p>\n
Note: the standard<\/p>\n
System Settings \u2192 Keyboard \u2192 Shortcuts\u00a0 method *does not work* for me in Plasma 6.6.6.\u00a0 I get the error “”Error while communicating with the global shortcuts service.”.\u00a0 Instead, I had to do it using the KDE Menu Editor.<\/p>\n
