The Linux Terminal Server Project team have released version 5.2 after two years and almost one thousand commits. It has become one pretty powerful product! I like the ability to “run the whole session remotely or run select applications locally to use specific hardware or advance 3D capabilities.”
This is an awesome development. The Moblin team has modified the Xserver which allows it to run as a non-root user. Previously X had to run as root to communicate directly with video hardware, but now thanks to GEM and kernel mode-setting that’s no longer required. Yay.
A fine example of everyone benefiting from free software.
Prior to the purchase of brand new workstations at work, Justin and Andy were working from Macbook Pro laptops. We had these Matrox DualHead2Go boxes which took a video signal and split it in two, for the purposes of connecting two monitors to a non-dualhead video card. I cannot tell you how much of a pain it was getting not only DVI output working under Linux through the proprietary ATI driver (although now that I know how, it’s pretty easy), but also getting it to talk to these Matrox boxes.. modelines.. resolutions.. triple displays.. gahh..
Never-the-less, I did get it to work. The final setup consisted of the laptop screen being enabled as the primary desktop, then the secondary desktop through the DVI output connecting to the Matrox box at a resolution of 2560×1024, which the box then split across two LCD screens. One of the problems was that the DPI resolution for the dualscreen setup was very wrong and as a result the fonts on the monitors were TINY.
So, the next trick was to tell the secondary monitor (the dualview box) what DPI it should run at (in this case, 96×96).
Even on my main box at work using the NVIDIA driver on a dualscreen setup, the DPI is wrong. chris@gentoo ~ $ xdpyinfo |grep -A1 dimensions
