In launcher after 1.22
we switch TWM to Awesome for global notification window and prevent focus-stealing and maybe other features
This is an introduction to the pre-trial. if you are not good at linux console
Later, there will be an official release.
So do it on your own risk
Manually, you need ssh into gameshell
make sure you have launcher >= 1.21 running with bluetooth support(sudo apt-get install bluez bluetooth)
Upgrade launcher
currently there is no release hash for launcher ,so you just need to
cd /home/cpi/apps/launcher
git pull
then move launcher out of /home/cpi/apps/ to /home/cpi/
The launcher will become more independent so that we can backup the user data easier in the future
mkdir /home/cpi/apps/Menu
Create a folder named Menu , this folder is for games/apps
We can put our games/apps, which was previously needed to place in the /home/cpi/apps/launcher/Menu/GameShell , into this directory (not belong to launcher`s)
and the games/apps folder is the all-in-one style
the icon ,the startup script, and others be in one simple folder, no need to put icon and script apart like before(
scripts in /home/cpi/apps/launcher/Menu/GameShell and icons in /home/cpi/apps/launcher/skin/default/Menu/GameShell/)
games/apps folder examples:
All of the above examples come from the forum players, thank you all, I just borrowed , I hope you wouldn’t mind
Then change the bottom of /home/cpi/.bashrc to point X to use new .xinitrc inside launcher
if [ -f /tmp/autologin ]
then
rm -f /tmp/autologin
mpd ~/.mpd.conf
startx /home/cpi/launcher/.xinitrc -- -nocursor > /dev/null 2>&1
fi
.xinitrc
feh --bg-center ~/launcher/sys.py/gameshell/wallpaper/loading.png
exec ~/launcher/load.sh &
exec ~/launcher/sys.py/gsnotify/gsnotify-arm &
exec awesome -c ~/launcher/awesome/rc.lua
Here is , new .xinitrc invoked a small widget called gsnotify
gsnotify
Though the readme of gsnotify ,there are 3 examples
one of them is the battery notify script
#!/bin/bash
BAT_PNT=`upower -i $(upower -e | grep 'battery') | grep -E "state|to\ full|percentage" | awk '/perc/{print $2}' | cut -d % -f1 `
if [ "$BAT_PNT" -lt "20" ]; then
if [ "$BAT_PNT" -lt "15" ]; then
echo '{"type":"once","content":"Power<15%"}'
fi
if [ "$BAT_PNT" -lt "10" ]; then
echo "keydown" | socat - UNIX-CONNECT:/tmp/gameshell
echo '{"type":"repeat","content":"Power<10%,will poweroff soon"}'
fi
echo "keydown" | socat - UNIX-CONNECT:/tmp/gameshell
echo '{"type":"once","content":"Power<20%"}'
else
echo $BAT_PNT
fi
the script use upower to check the battery ,get percent
and use socat to communicate launcher’s unix socket under /tmp/ to light the screen if the screen is in dark
and of cause ,print the message to gsnotify to show up
you can put the script into /home/cpi/launcher/sys.py/gsnotify/Jobs now
The gsnotify will do a round-robin check every 30s for the scripts under /home/cpi/launcher/sys.py/gsnotify/Jobs directory in simple json return formatted and
show a small window that slides down from the top, reminding the battery that it is nearly exhausted, etc.
and freely configurable
Install awesome and upower
sudo apt-get install awesome socat upower
--reboot--
Fix RetroArch issue
Even All is done ,you will not see any notifications while retroarch is running,because
the retroarch in GS ,is kind a wild window for X11 currently now
so change config to fix this issue by two lines:
in top of /home/cpi/.config/retroarch/retroarch.cfg
video_fullscreen = "false"
...
video_windowed_fullscreen = "true"
–reboot–
Options
upgrade to debian buster to get newer software
in /etc/apt/source.list
change all source to buster
then upgrade the debian system
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install awesome socat upower
--reboot--
At end:
In the new launcher , we use Awesome to deal on-top windows ,even the battery monitor widget can work better , no need to kill and re-launch it time by time
I apologize for my bad English. If you have any accidents during the actual operation or do not understand my explanation, please let me know, let’s do more tests together.
