Here is a growing list of tips, tricks and configuration snippets for using Sxmo.
This pages is intended to focus mostly on "non-core" issues, such as running apps and everyday usability. The core configuration issues should end up in sxmo doc, as discussed on https://todo.sr.ht/~mil/sxmo-tickets/275
Calls, SMS, Modem
Sometimes Modem gets stuck
Sometimes the modem gets irresponsive, stops receiving/sending calls, even when toggled. Rebooting sometimes doesn't change this situation as it seems the modem then needs a hard reset.
Prefered solution: remove battery and reboot.
Sometimes SMS dont get sent/received
It may be a problem with MMS getting "stuck" in the pile, not being processed, and blocking further processing of SMS.
One solution involves mmsd-ng
Another solution is to manually use Modem Manager to delete the incriminated mms:
mmcli --modem 0 --messaging-list-sms
mmcli --modem 0 --sms 0
mmcli --modem 0 --messaging-delete-sms=##
mmcli --modem -r
(the identifying number of the modem may vary, being incremented upon toggles and sometimes reboots. you probably also can use --modem any
)
How to send an SMS via command line (or ssh)
cat mysupersmsfile | sxmo_modemsendsms.sh +33123123123 -
General configuration
How to easily change the size of the text, system-wide?
Change the value in: /usr/share/sxmo/appcfg/xresources_xft.xr (try 160!)
Xft.dpi: 192
if you remove the dpi line there you can set dpi on the fly via
xrandr --dpi x
How to launch programms on startup?
The easy way is to edit the following file:
vi .config/sxmo/xinit
and add your programms somewhere. Warning: they have to execute quickly and/or not keep stay in focus, or the window manager won't start (don't forget to add "&" at the end)
make /tmp/ in RAM, to save write cycles on EMMC
add the following in /etc/fstab
tmpfs /tmp tmpfs rw,nodev 0 0
How to customize the colours/fonts of the interface?
Get example in the alpine blooms theme by Tetrakist, as entries to add in /home/user/.Xresources
Some notifications stay stuck on the screen!
pkill dunst
- launch nmtui (a rotated screen is usually better)
- add a new connection, type "ethernet" for interface "usb0", in ipv4 settings chose "shared".
- you may want to uncheck "automatically connect", so you can manually activate it later, when you need it, in the "networks" dmenu.
- activate that connection.
voilà!
Applications specific
Pure-maps sort of works (using OpenTopo or Sputnik tiles), as well as Marble (QT/KDE, heavy...). Unsure yet how to make the GPS work for both of these, but it has reported being feasible...
Apparently a good start to enable GPS should be:
sudo /etc/gpsd/device-hook "" ACTIVATE
then...?
QT app (vlc-qt, etc.) doesnt fit the screen!
try adding the following in your .config/sxmo/xinit
export QT_AUTO_SCREEN_SCALE_FACTOR=1
export QT_SCALE_FACTOR=0.7
(change the factor until it suits your need)
