I have not had many problems using the viewsonice vg171b or currently the vx800. I use a compaq evo n800x laptop with an ati radeon 7500 video card. I am currently using slackware 9.1 but have previously used Red Hat 8 and 9. One cautionary note, the latest redhat update for xfree86 did mess up my xconfiguration on my redhat install pretty bad so that the flat panel did not work in its native resolution (1280x1024) I eventually hacked my xf86config enough that I got it working again, but it still isn't the same. I also have my boss running redhat 9 on an ibm thinkpad using the viewsonic vx800 and it works fine.
