Do you use LPMs for your LFSRs?

I want to implement an LFSR as a means of generating random numbers but I'm not sure whether to use an LPM or just code it in a process. I would be interested to hear how you choose to implement them...

By using the simulator within Quartus, I just ran the simulator, expecting to see 'output' change value each clock cycle but it is a constant value of '1'. It seems that the output sticks at whatever value I set the seed to be, i.e. a seed of 1111 resuts in a constant output of 15.
