Hi, I got the same problem with Acer Veriton N2620G, though what I tried to install is Ubuntu 12.10, like Hunter had mentioned above, the same symptom was encountered. Some modification were made that made the installation successful with Ubuntu but without the optimal performance. The unit is okay with Debian, no problem at all.

Acer Philippines relayed to us Acer HQ’s (Taiwan) advice:

As of this moment, only Debian Linux is tested to run with this Veriton model.
