They are well supported +by open source drivers. There are, however, a couple of issues that may require +some work arounds. + +**Resolution Issue** + +There is a limitation with certain cards which limits the total resolution to +2048x2048, so both monitors can not have a total resolution totaling more than +that. To work around this it may be necessary to position your monitor as a top +or bottom monitor as opposed to the typical side by side setup. This can easily +be accomplished through your desktop's control of monitors. Please see the +sections on dual monitors with KDE and GNOME above. + +**Primary Monitor Issues** + +With certain cards your system may get confused on what is the primary display. +For example many users will be using a laptop. You will want your laptop screen +to be the primary screen, and your projector to be the secondary monitor. +Certain Intel cards reverse this. To work around this you will need to know the +name of your monitor. If you are a KDE user this info is given to you in the +display settings. If you are not using KDE enter the following in a terminal +without your projector connected to your computer:: + + user@linux:~ $ xrandr -q + +This will give you a long string of output. Screen names will be something along +the lines of LVDM, VGA-0 or some convention similar to that. Without your +projector connected to your computer only one monitor will show as being +connected. That will be the monitor you will need to use as the primary. Now +connect your projector and enter:: + + user@linux:~ $ xrandr --output LVDM --primary + +**Note** it has been reported that when this issue is occurring you will not +want to connect your projector until your desktop is running.
