I've finally managed to get several media-directors to boot from the LAN and it's work fine apart from the fact that my settings in the XOrg.conf file do not appear to be kept.
One of my MDs is an older HP laptop. The graphics card inside it is an ATI Radeon Mobile chipset, however Pluto appears to think that this is a Radeon 8500 or newer. When it failis to load this module, it resorts to VESA which fails miserably.
If I change the xorg.conf module to "ati" for this particular MD, for the duration that the core is up it works fine, however as soon as I reboot the MD or the core, it looses the settings.
Is there a way of making this change permanent?
