[Bug 374459] Re: Acer Aspire 5738G: touchpad can be switched off, but not on again

[PhobosK]

Still not fixed for Acer Aspire 7738G (look #57 here too):

1. modprobe -r psmouse && modprobe psmouse - works when the button is in turned off state (not lit)
2. i8042.nomux kernel option works but makes the side scrollarea (it has a separate area for scroll - http://www.notebookcheck.net/typo3temp/pics/931e067a0d.jpg) stop working properly


Ubuntu 9.10 all latest packages and kernel.
