VRE01 woes

Ok Now, I stuffed my dell with 4 videocards, 3 matrox millennium cheapies with 8mb ram, one s3 was on-board and installed xf86, so my mouse now jumps from the 19in lcd to the 19in tube and to the 19in VRE01 and I have all the visual real estate I ever need....but: The trouble is the VRE01 is kind of flickery with about 12 vertical areas top to bottom that seem to "shimmy" slightly in -bpp16. no you cannot run --bpp8 for a single card. And not --bpp4 or 2 either in that server. But its not that methinks, it looks more like a slightly out-of-tune synch sig. sync on green enabled on that card of course. Or a secondary "overlay" frequency that creates a crazy harmonic? Barely!? Has anyone else tried? Getting a b/w VRE01 gasplasma display to display with an xfree server in linux? b/w dithered? Its my ambition....I'm almost there! What am-I doing wrong?? fred
