I don't know specifically about the t420, but x220 with HD 3000 works just fine multi-screen using xrandr, I use mine with a DP-to-DVI cable. $ dmesg | grep vga vga1 at pci0 dev 2 function 0 "Intel HD Graphics 3000" rev 0x09 intagp0 at vga1 inteldrm0 at vga1 wsdisplay0 at vga1 mux 1: console (std, vt100 emulation) $ xrandr Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 434mm x 270mm 1680x1050 59.9*+ 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 DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis)
