I have good news for laptop users with built in ALPS Touchpads. Acer/Gateway (same company) have been generous to create a new driver for Windows 8 32/64-bit users.
To make sure that your ALPS Touchpad may be compatible with this new driver for Windows 8, make sure that before upgrading to Windows 8, in Windows 7 open Device Manager, check the "Mice and other pointing devices" category and your Touchpad should be listed as "ALPS Pointing-device".
If it is, then you are a candidate to install the newly released drivers. Click the link for a direct download from Gateway.

1. Unzip the file.
2. Double-click on setup icon and install.
After installation, this new driver adds Windows 8 gestures that are found on Microsoft Surface and other tablets for the TouchPad. There are other features there, but those are up to you to experiment with.
You can access the TouchPad settings by either clicking the TouchPad icon in the taskbar or by going to Mouse Properties in Control Panel.
For users that have tried this driver and the swipe gestures do not work, it might be that your ALPS TouchPad uses a slightly different driver. Here are some alternative Windows 8 ALPS TouchPad drivers available.
I have not tested these, but users from other forums say these drivers have worked for them. Proceed with caution.
