Hi,

I have nvidia-optimus card and Elantech touchpad.

I've just built Elantech drivers in kernel, before I used generic drivers. It was detected as Logitech PS/2 mouse, scrollbars didn't work.

Now scrollbars work but sometimes (quite often) it freezes X and I should switch to VT1 and back to restore interactivity.

Can I have both scrollbars and normal work of X?

I'll attach everything you ask, but I don't know what.

Kernel:
uname -a
Linux szldlc 3.13.7-gentoo #4 SMP Mon Apr 28 09:00:08 CEST 2014 x86_64 Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz GenuineIntel GNU/Linux


Thanks in advance.

Arre your GPU drivers modprobed correctly? Try re-modprobing them (as root)
Code:
modprobe -r vga

than restart your computer.

Roll back to the kernel without support of Elantech driver. It's impossible to work like that, I can continue to work without touchpad scrolling
