Pulsar Mouse Linux, an unofficial configuration tool for Pulsar gaming mice on Linux, has been released in versions v0.1.26, v0.1.27, v0.1.28 and v0.1.29.

The four updates mainly bring fixes for the Xlite V3 and Xlite V4 and better detection of the mouse model. The issues were reported by @variasjon, @bluesceada and @f-o-o-g-s.

Version 0.1.26:

• Xlite V4: Lift-off distance was read incorrectly (1.0 mm showed as “2 mm”) and is now written correctly. The mouse has six profiles instead of five, and the DPI range goes up to 32,000 in steps of 10.
• Button count: Four mice share the same USB IDs, but only the X2A Wireless has four thumb buttons. The driver now reads the model ID and hides “Thumb 3” and “Thumb 4” on six-button models.
• Model identification: pulsar-mouse now prints the model of the mouse.

Version 0.1.27:

• Profile export produced no bindings on the Xlite V3, X2 V2 and X2 V2 Mini. Each button is now handled separately.
• The settings window is rebuilt once the driver knows the actual model.
• The 1K dongle now asks which mouse is paired and uses its profile count, DPI range and lift-off values. An X3 behind the dongle can now reach 0.7 mm lift-off.
• The CLI now validates --profile against the mouse’s real profile count.

Version 0.1.28:

• The GUI did not open on Ubuntu 24.04 LTS, because Adw.ButtonRow requires libadwaita 1.6 (Ubuntu ships 1.5). The rows now fall back to an ActionRow. CI also builds the real window against a stub mouse now.

Version 0.1.29:

• Button count for 21 models sharing the USB IDs 3554:f507 and 3554:f508: models without the X2A Wireless layout lose the extra pair of buttons (seven or five remappable buttons).
• Register 0xAD for the sleep timer is now only written on the X2 CrazyLight and drivers derived from it.
• USB ID 3554:f509 is now supported (untested).
