Hello,

I have an all-in-one tablet-like PC with a builtin monitor (LVDS1) and 2nd
hotpluggable monitor (VGA1), using the intel graphics driver.

My problem in a few words: if I don't have a 2nd screen plugged in at boot,
I can't see a thing once X loads. If I have a 2nd screen plugged in at boot,
everything works more-or-less ok.

Details of unit:

   - Xorg: 1.7.6
   - Linux: 2.6.32-27-generic (and I've also tried with the very latest
   2.6.38 Ubuntu Natty Narwhal kernel, same problem)
   - Ubuntu: 10.04 Lucid Lynx
   - Graphics card: Intel Mobile 945GM/GMS/GME, 943/940GML Express
   Integrated Graphics Controller (rev 03)
   - Unit: Axiomtek     GOT-5100T-830    All-in-One    10.4” SVGA TFT
   Fanless Touch Panel Computer with Intel® AtomTM N270 Processor Onboard


More detail: If I have VGA1 unplugged at boot, X detects it (VGA1) as
primary for some reason, and shows a blank screen on LVDS1 (but during BIOS
load, grub, and plymouth splash, the picture shows on LVDS1 as expected. I'd
expect X to do the same, but it doesn't). When I plug in VGA1, the picture
shows up fine on there, but no pic on LVDS1 until I load up Monitor
Preferences or use xrandr. If VGA1 is plugged in during boot, then both
screens operate as expected.

I want it to boot smoothly, with no flicker, in both situations (2nd screen
plugged & unplugged), so using xrandr dynamically after X loads isn't really
an option.

   - Xorg.conf: none (I've tried various xorg.conf settings, but none help,
   so it works just as badly with no config file)
   - lspci: http://pastebin.com/n6bPhupW
   - xrandr --verbose: http://pastebin.com/0gmRWARM
   - Xorg.log withOUT 2nd monitor attached:

   - Xorg.log WITH 2nd monitor attached: http://pastebin.com/wP1VEvHJ

Can anyone help me delve further into the problem? Perhaps even help fix it?
;-)

I'd be very keen to chat with someone in person (Skype or something), if
that's appropriate -- but I'm more than happy to discuss via this list if
that's better.

Kind regards,
Bryan
