Stephan has helped me through my first kernel patch, and I am following along with the steps he took pertaining to the following bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/544671 I am working on a bug located here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/907055 and have already submitted a patch. Mr Salisbury recommended I contact the upstream developers in order to have them work this in to the next release, so here I am. I have an Intel Atom thin clients with Intel 945GM video cards installed. They report an LVDS output as active, even though these thin clients do not have a monitor attached. This is causing the clients to boot in dual-head mode, with one monitor missing. Thanks everyone for your time. The bug above has the patch listed in there, but I will include it again below: --- ./intel_lvds.old 2011-12-20 13:25:49.368291249 -0500 +++ ./intel_lvds.c 2011-12-20 13:26:05.160291248 -0500 @@ -709,6 +709,14 @@ }, { .callback = intel_no_lvds_dmi_callback, + .ident = "Clientron E830", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Clientron"), + DMI_MATCH(DMI_PRODUCT_NAME, "E830"), + }, + }, + { + .callback = intel_no_lvds_dmi_callback, .ident = "Asus EeeBox PC EB1007", .matches = { DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK Computer INC."),
