This kind of works on my Sony C1VFK laptop. That is, it works as is, although it starts off by showing a "black screen" but then seems to recover and finally works OK. However, on my machine which has a very small screen I have to use a Viewport and an unusual Mode ========================================== SubSection "Display" Viewport 1024 480 Virtual 1024 768 Depth 16 Modes "1024x480" "800x600" "640x480" EndSubSection ========================================== with Modeline "1024x480" 65.00 1024 1032 1176 1344 480 488 494 560 -hsync -vsync and the laptop does not accept this (which worked with FC-1). So I guess my problem is the "Monitor" settings. Your hsync/vsync settings were more generous than my laptop seems to allow, but that didn't seem to matter. But thanks very much for your help. I guess I need to learn a bit about the settings in xorg.conf , which currently are a bit of a mystery to me. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
