I have recently had good luck with on-board video and nVidia hardware, but _not_ with the nVidia proprietary driver. Generally for LinuxCNC the open source or vesa driver works much better. I just got a couple of these: http://www.ebay.com/itm/360434878243 and added memory for 512MB total. I also needed to edit xorg.conf to add monitor refresh rate and resolution. They have decent latency at 38000 nS (38 uS). and DVI. This was the first time I used a USB thumb drive to install Ubuntu. My CD was giving me fits, so i tried the thumb drive and it was flawless. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
