<title><filename>/dev/i2c-*</filename> versus PCI memory</title>
|
|
<para>To control a monitor, DDCcontrol must access the I2C bus of the
|
|
graphics card. There are two methods to do so: the first one uses
|
|
<filename>/dev/i2c-*</filename> devices provided by kernel drivers (abbreviated
|
|
as dev in tables), the second one reads and writes directly in the card PCI
|
|
memory (abbreviated as PCI in the tables).</para>
|
|
<para>Depending on your hardware, one method or the other may work. Even both may work.</para>
