I have one more question which possibly relates to this motherboard and the Live LinuxCNC: linuxcnc-2.7-wheezy.iso
Is it just the on board video or is it a general problem with Debian LXDE desktop? I've seen complaints on the Pi Forums from a year ago on desktop size. There are lots of other hits where people are complaining but not much in the way of solutions. An example is here: http://www.autoartisans.com/cnc/LXDE_BigDesktop.jpg The monitor appears to be a window into a much larger desktop. I've seen this on the Beagle when I put a 1080P monitor on it. The GEAR graphic is round. On a smaller monitor where it's been squeezed onto the monitor it's no longer round. Same with the swirly thing that is part of the default background. Round on this LinuxCNC install. Round on the Beagle with 1080P but oval with the Beagle on a smaller monitor. The Beagle Linux appears to work as expected. In the above screen grab example you can see the drop down menu is off the screen as is half the file system explorer. I've fixed the panel so it's narrower by setting it to 95% and there's the rub so to speak. If 95% makes it just a bit narrower then clearly the system must know how much is visible but the desktop itself appears to be 1920 wide with a height of 1080. After much searching I found a number of explanations on how to change this and none of them worked. Either the programs weren't there or they didn't really address what seems to be a simple problem. How do I tell the system that I want the desktop to be the same size as the monitor? When I run LinuxCNC Config Picker and then run say the parallel port Inch Version the AXIS window doesn't fit. The bottom is below the screen. So it must think it's on a bigger desktop too? Is this a Motherboard Video controller issue with Linux thinking it's a bigger screen or is it configuration issue?
