Of course LCDproc is not perfect (yet). We do our very best to improve it, but in some cases we are very much restricted in our efforts.
The main reason for that is the fact that we do NOT have all the hardware people have written drivers for. Unfortunately some developers have kind of vanished and don't react to mails from the mailing list any more.
So, as far as drivers are concerned we rely on YOU as testers. We have developed elaborate "coding in the dark" skills over the time. E.g. the CFontz driver has been updated and ported to 0.4.3 without the developers having the hardware.
