I have a Toshiba Satellite C640. I have installed Linux Mint 14. I want to connect two external monitors to it. Although I have only one VGA port. I have an external USB to VGA card which I connected, but it did not detect the second monitor on the USB to VGA card. Can I get some help?


I am trying to connect it via this adapter.

I assume the USB to VGA adapter requires specific drivers. Did you check if they are available for Linux, and if so, did you install them? That type of hardware is unlikely to be plug-and-play, especially on Linux. –  nhinkle Jun 15 '13 at 5:55
No I didnt check for drivers. –  Indradhanush Gupta Jun 15 '13 at 5:55
Is this question about using a single VGA port, or is it about using a USB video card? –  Ignacio Vazquez-Abrams Jun 15 '13 at 5:57
@IgnacioVazquez-Abrams I have already used the VGA port to connect a Monitor. I want to connect another via a VGA-TO_USB converter in a USB port. –  Indradhanush Gupta Jun 15 '13 at 5:58
Umm, this might be a bit dumb but you keep saying VGA to USB, don't you need USB to VGA? A VGA to USB adapter would be a capture card, and could only take video in, not send it out. Can you tell us who makes your adapter and what its model number is? –  Scott Chamberlain Jun 15 '13 at 8:39
