# Function to list value(s) of graphics adapter
# attributes monitor_type and resolution refresh
# rate. Designed to be similar to produce output
# from lsattr command.
# arguments are as followed:
#    1st argument is device name
#    2nd argument is the attribute name
#    3rd argument is the flag to indicate
#        whether current value or list of
#        values is desired
