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:

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?


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.

  • I already tried how you have suggested,but system is unable to detect the projector,while it working fine in windows. – Mahesh.D Jan 29 '13 at 7:24

Simpler solution : Use the VGA input

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

Step 1 Identify your adapter

  • lsub can be used to identify your adapter
  • The contains 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.
