Comment 15 for bug 1275416

Cheers mates!

I've found a workaround for this REALLY odd ubuntu issue.

Assuming you all have ELAN touchscreen devices, like mine, it represents an usb device.

It seems that the ubuntu driver that controls the touchscreen has a bug, altough it could work natively as another xinput device.

So, I blacklisted the "usbtouchscreen" on modprobe, using the command:
"echo "blacklist usbtouchscreen" | sudo tee -a /etc/modprobe.d/blacklist.conf" (without quotes, of course)

or just blacklist it using nano, as you prefer... :-)

Reboot the thing and... voilà!

Touchscreen works every time, no matter how many resume/suspend events you inflict to the beast.

It's working just fine for me. So, guys, tell if it solves for you too!

Have fun!
