I'm using an Epson EB-S9 projector and it is connected using a USB cable to the Ubuntu system, but the problem is that the system does not detect it. Below is some information regarding my system:

lspci | grep VGA

Output is:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

sudo lshw -C video

The output is:

    *-display 
description: VGA compatible controller
product: Core Processor Integrated Graphics Controller
vendor: Intel Corporation
physical id: 2
bus info: pci@0000:00:02.0
version: 02
width: 64 bits
clock: 33MHz
capabilities: msi pm vga_controller bus_master cap_list rom
configuration: driver=i915 latency=0
resources: irq:42 memory:fe000000-fe3fffff memory:d0000000-dfffffff ioport:f160(size=8)

I'm thinking that the necessary drivers might be missing. How can I install them?

Simpler solution : Use the VGA input

If this is not an option, you can always try the following:

Step 1 Identify your adapter

  • lsusb can be used to identify your adapter
  • The contents of /var/log/syslog just after plugging-in your adapter may contain some information, like is a driver loaded, or if a problem happened (firmware missing, ...).

Step 2 - Fix the problem

Once your adapter is really identified, you can search on the internet which USB-to-display adapter it is, and if there is a driver available for your favorite Linux distribution.

Open "monitors" using unity and press "detect monitor" to discover the newly added monitor to detect.

Connection is done using usb so use lsusb to cheek the connection.
