Blank Screen/External Monitor Issues

I'm running Arch on a Dell Latitude E5510, and ran into an issue with the laptop's display during boot.  (My problems are exactly as described in this post: https://bbs.archlinux.org/viewtopic.php?pid=820097)  A quick "nomodeset" fixed that, though it crippled any support for an external monitor.  After some digging around, I discovered the "video=SVIDEO-1:d" fix, which now allows me to use an external monitor with the latest Intel driver (yay!), but the screen on the laptop is blank. 

xrandr detects the laptop monitor...

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
eDP1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1366x768       60.0 +
   1024x768       60.0* 
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 509mm x 286mm
   1920x1080      60.0*+
   1280x1024      75.0     60.0  
   1152x864       75.0  
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   640x480        75.0     60.0  
   720x400        70.1  

And if I run "xrandr --output eDP1 --mode 1024x768", the laptop's screen tries to adjust itself, but there is still no output.

(Following the suggestions in the thread linked above prove unfruitful... I've inspected /sys/class/backlight/acpi_video0/brightness, and it's set to 15, so lurker's fix does nothing for me.)

Thanks in advance.
