Mouse e teclado não funcionam (atraso extremo) após nova instalação do Linux Mint 17.1

3

Depois de instalar o Linux Mint Cinnamon 17,1 (32 bits) no meu laptop vaio z, o mouse e o teclado começam a funcionar por alguns segundos, depois congelam e continuam a trabalhar de forma muito intermitente. Por exemplo, eu acerto a super-chave e em algum momento dentro dos próximos 10mins o menu aparecerá - assim como um atraso extremo. Como posso remediar isso?

Por favor me aponte em qualquer direção. Tanto o mouse quanto o teclado funcionam bem no liveUSB e funcionam no BIOS. 'lsusb' retorna
