I have an Asus U30JC laptop with a VGA and HDMI ports. I can connect my external screen (1920×1200) to either of those ports but I wonder if I would be able to use two screens at the same time, one plugged to the VGA and the other to the HDMI socket.
Any ideas? Where should I find out?
Doing xrandr, I get:
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 164mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis)
When connected to the VGA external screen, I get:

What's the graphic chip on your pc? You could try plugging both screens in. Then run
Monitors
from the menu by pressing Super and typing Monitors. If they are both detected, you can configure them for dual screen use.
