I think you misunderstand. The issue is: certain video chipsets react badly to font changes outside the vertical retrace period. Using moused(8) on these chipsets is unbearable without the no-flicker code. The problem is that the no-flicker code slows things down a tad. Not much, but enough that you notice it if there's a lot of mouse activity. So those of us who don't have that problem may want to turn it off, unless we're always running X since it only affects text mode. DES -- Dag-Erling Smørgrav - dag-erli@ifi.uio.no
