lxinput's Issues

Why not read in the mouse speed directly

In read_mouse_speed (void) the mouse speed is read from the desktop configuration file written by the last run of lxinput.

But why not read it from the mouse directly? It may have been changed from elsewhere in the meantime...

In the shell it could be done like this, for example:

xinput --list-props "PixArt USB Optical Mouse" | grep "libinput Accel Speed (" | sed -e 's/^.*:\s*//'

---

(The usage of that config file ~/.config/autostart/LXinput-setup.desktop is indeed a bit strange, IMHO.)

lxinput doesn't work with e.g. German language setting (locale)

If the system is configured to use a language with decimal comma instead of decimal point (eg. German) lxinput creates a desktop file formatted with the locale in mind but fails reading it in again here:

void read_mouse_speed (void)
...
    FILE *fp = popen ("grep -Po \"Accel Speed\\\" [-.0-9]*\" ~/.config/autostart/LXinput-setup.desktop | head -1 | cut -f 3 -d ' '", "r");

In that line the decimal point is hard coded. Adding a comma in [-.0-9] makes it work:

    FILE *fp = popen ("grep -Po \"Accel Speed\\\" [-.,0-9]*\" ~/.config/autostart/LXinput-setup.desktop | head -1 | cut -f 3 -d ' '", "r");

So the mouse speed is reset to default on every call of lxinput.
