Hi Andy,
Thanks for the suggestion -- unfortunately, it looks like my situation is a little different. I'm booting into runlevel 3 -- and text-mode screens work without a hitch on both the LCD and CRT. Now that I'm doing this, I can startx -- and at least get a good display on the laptop. But the external CRT goes scrambled at this point.
Interestingly enough, dropping back out of X restores the CRT just fine to text mode -- but the *laptop* display goes nuts. Cycling through the internal/external display options with the Fn-F8 key combination gets me back to good screens on both displays.
But I still don't have XWindows on my big monitor, which is what I need when I'm in the office. Anyone have any suggestions for me?
Thanks in advance,
Allan

Does your laptop have a Fn-key combo to swap between the main LCD and external
VGA? On my Inspiron 5150 I despaired of getting Twinview to work, due to
very strange artefacts on the VGA port video only (as if the pixel clock was
being modulated). However, I found that if I did Fn-F8 at boot-time, before
the grub screen, then the BIOS correctly inited the second head, and twinview
works great after that. So I would try that and see if there are any updated
laptop BIOSes about.
