Добрый день.

Прошу помочь разобраться со странной проблемой: после перезагрузки ОС отваливается тачпад (его нет в системе).
Но стоит перезагрузиться в Винду, а после опять в линукс, как тачпад появляется и работает до следующей перезагрузки.

1. Используемые иксы - xfce 4.12

2. Тачпад: CyPS/2 Cypress Trackpad
/dev/input/mice
/dev/input/mouse0
Bus: PS/2
Device Numbers:
Major: 13
Minor: 63
Range: 1
Type:c

3. uname -a

4. cat /etc/SUSE-brand

7. Опция для GRUB2 в cmdline «psmouse.proto=cyps» не помогает.

8. Компонент «xf86-input-synaptics» установлен.
