If you call xrandr with no parameters the user should see what video ports are available. Here is what I get: xrandr Screen 0: minimum 8 x 8, current 1024 x 768, maximum 8192 x 8192 DVI-I-0 disconnected primary (normal left inverted right x axis y axis) VGA-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 480mm x 270mm 1920x1080 60.0 + 1440x900 59.9 1280x1024 75.0 60.0 1280x800 59.8 1152x864 75.0 1024x768 70.1* 60.0 800x600 60.3 56.2 640x480 59.9 I use XFCE instead of KDE most of the time but xrandr works with either. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
