Everything works OK almost all the time. One time I had a problem with MDM not working on the boot, so swapped out the fglrx-udates video driver for the fglrx video driver and not had any further problems. I was able to do that at the tty1 login screen using apt-get install process. Running a Sempron 145 processor by AMD on the system, so very power saving with the added saving from an ANTEC 80% PSU. Fans rarely come on, and never when sitting in idle, so leave it on all the time.
