- I have an A4000 running GfxBase X11 with the GDA-1 card on a Mitsubishi
- Diamondscan 16 at 1024x800x8. I use a 15-pin AB switchbox to switch between
- the Amiga video out and the GDA-1. This is a very nice setup except for the
- syncing difficulties that the Mitsubishi has with the AGA output. I ran this
- same setup on an A3000 and the Mitsubishi would almost instantly sync to the
- deinterlacer output on the A3000. I miss that.
-
- Haven't ever gotten around to running Xspecs, but wrt speed this thing feels
- pretty close to a Sparc1 with no graphics accellerator. Very livable. There
- were some PC-based servers running on 486 boxes around here for a while, but
- it was about like running X11 in 16 colors on an A2500 and they eventually
- quit using them. Don't know about the OS2.0-based X11 servers though.
- Supposedly they are faster.
-
- One thing I really like about running X11 on the Amiga is that I can toggle
- to other Amiga screens. Now this may sound pretty trivial to most X users,
- but it is so significant that even when I work on a Sun 4/640 multiprocessor
- machine, I get a bit claustrophobic. Usre it's a heck of a lot faster, but
- it's a bit like comparing MS-DOS to the Amiga's multitasking capabilities. I
- simply have more options and that makes my life much easier.

- The current native Amiga graphics R4 server works fine with AGA output up to
- 5 bitplanes if I remember correctly. Beyond that, the color palette gets a
- little confused, and it runs pretty slow, but there were no ill effects.

- YES! Very stable. In the three or so years that I have used GfxBase X11 on
- A2500, A3000's and this A4000, the only times I remember having trouble with
- it was when another program trashed the server. In other words, no complaints
- and no real suggested improvements (other than X11 R5 :^) and I use it pretty
- much all day long for analyzing data and for developing X11/Unix applications.
