Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-* must exist and the logged on user must have read/write permission for those devices (or at least those devices associated with monitors). Typically, this access is enabled by: - setting the group for /dev/i2c-* to i2c - setting group RW permissions for /dev/i2c-* - making the current user a member of group i2c Alternatively, this could be enabled by just giving everyone RW permission The following tests probe for these conditions.
