Несколько дней тому как после ХЗ какого обновления ХЗ чего появились странности в работе тачпада: нестабильное поведение (скачки по экрану), гиперчувствительность (спонтанные нажатия), не работает прокрутка пальцами и т.п.
При отключении настроек synclient и перезагрузки все приходит в норму. Настройки простые, задействована эмуляция нажатия средней кнопки мыши:
TapButton3=2
Настройки подгружаются просто из скрипта в /home/bin
Не знаю, где чинить.
В принципе работать без эмулирования средней кнопки можно, но крайне неудобно: много лишних пальцедвижений.
Если знаете, куда смотерть и что делать - подскажите.
Тачпад:
