How can I set a display resolution of 1366x768 in a Acer Aspire One ZG5 within Ubuntu 12.04? The only resolutions available are 1280x768 and 800x600.
Answer: It is not possible to set the display resolution to 1366x768 in a Acer Aspire One ZG5. The Acer Aspire One ZG5 does not support resolutions higher than 1024x600.
As you have 1280x768 listed under System Settings > Displays, it is very likely you do not have an Acer Apsire One ZG5. Ubuntu 12.04 will correctly detect the display's native resolutions and populate the settings appropriately during installation.
I believe what he is talking about is DOWNSCALING on the ZG5.
There is a program for windows that downscales 1024x768 on a realtime 1024x600 display. It is called a1ctl.
The result is that the picture is not that good. The upside is that you can see the entire normal screen which is important for some programs and some games. That is why a downscaling program for ubuntu, any flavor of ubuntu, linux is so important.
In the future I may be working with small tft screens with omap processors for robotics. If UBUNTU has downscaling I would rather go with them rather than creating custom installations of Gentoo!!!
