Tengo un problema persistente con el panel táctil de mi computadora portátil HP 2000, que tiene arranque dual con Ubuntu 20.04 y Windows 7. El panel táctil no responde y no registra ningún clic o toque, lo que lo deja inutilizable. Curiosamente, el problema del panel táctil se resolvió temporalmente cuando ejecuté Windows 7 en modo seguro, pero el problema finalmente volvió y ya no se soluciona en modo seguro.
El panel táctil de mi computadora portátil HP 2000 no responde ni en Ubuntu 20.04 ni en Windows 7. No puedo usarlo para navegar ni hacer clic. Curiosamente, un ratón externo funciona perfectamente bien. Inicialmente, el problema se solucionó una vez cuando ejecuté Windows 7 en modo seguro, pero esta solución ya no es efectiva. Esto me lleva a creer que es posible que el problema no esté estrictamente relacionado con el hardware. El problema persiste incluso cuando Ubuntu se ejecuta en vivo en una unidad flash.
