If you’re using xrandr on a box with an Intel graphics chip in order to setup your dual displays then you might have noticed that GNOME moves its main panel to the monitor connected to the external VGA port.\u00a0 This happens because the Intel chip says that the external VGA is the primary port and the laptop LCD is the secondary and GNOME happily accepts this.\u00a0 With some applications, like MythTV or OpenOffice, you can specify which monitor is the primary and secondary display, but not with GNOME.\u00a0 You’re stuck with the panel moving to the external display.<\/p>\n
As far as I know this is something that only the Intel based chips do when working with dual monitors.\u00a0 GNOME on dual monitors for other graphics systems doesn’t appear to behave this way.<\/p>\n
This can suck if the external display has a much smaller resolution than the laptop because all your finely tuned launchers, drawers and panel applications will get squeezed together on that external monitor but not put back to their correct positions when you switch back.\u00a0 This is one reason I switch to a different user when I do my presentations at user group meetings since I can’t guarantee what the resolution of the projector will be.<\/p>\n
I’m not sure if KDE exhibits this problem but I vaguely remember someone saying KDE figures out what’s going and and does the right thing (leaves the panels on the laptop LCD).\u00a0 Since I don’t use KDE (and don’t feel like logging out and then back into a separate session to test it) I can’t tell you what will happen.\u00a0 Feel free to comment on your experiences here.<\/p>\n","protected":false},"excerpt":{"rendered":"
