Vertical Scroll doesn't work on a Sony Vaio VPCEB1S1E

I have an Sony Vaio VPCEB1S1E that I have dual booting Windows 7 and Ubuntu all 64 bit In ubuntu I don't have vertical scroll. Same thing happens with Fedora 15,Linuxmint11 of course 64 bit If someone has a solution .........?

Solution 1:

It's known that the touchpad of vaio-E series have problems. However, you should at least get vertical scrolling - at least I do.

You can try editing /etc/default/grub and make the following change to the GRUB_CMDLINE_LINUX_DEFAULT line:

GRUB_CMDLINE_LINUX_DEFAULT="8042.reset i8042.nomux i8042.nopnp i8042.noloop"

then run sudo update-grub

If there were previous values (like quiet splash) to GRUB_CMDLINE_LINUX_DEFAULT leave them. This will disable the multi-touch features of the touchpad (but that probably didn't work anyway.
