Comment 32 for bug 1315360

I had abandoned Linux distros for a while because the shitty support for Razer products, but for work reasons I installed Ubuntu 14.04 back (I tried Ubuntu 14.10 on my Blade, but the system crashes every time I shut down or log out). I didn't expect multitouch would work since it didn't work on Ubuntu when I tried it months ago (it worked on Debian though, see #23).

But after I upgraded the kernel to 3.17.8-031708-generic, the multitouch worked again! It now works both on the first boot and on reboots, so I'm very happy with it.

However, I've noticed that the multitouch driver is not stable. Many things could affect it. For example, when the bumblebee driver is installed with

sudo apt-get install bumblebee primus

multitouch doesn't work, but removing the above and installing the driver with

sudo apt-get install bumblebee-nvidia primus

can fix the problem. Also, some people said multitouch didn't work on the first boot, it only worked after a reboot. Here's the solution:

I also found that after I connect the Blade with an external monitor, multitouch won't work after reboot (it'd still be working if I don't reboot or shutdown, of course). It won't even work after I unplug the external monitor and reboot. However, it will work if I unplug the monitor, completely shut down, and then boot up. I guess it had something to do with the xrandr command I used for setting up the resolutions and scalings for dual monitor.

Wired, but at least it works.
