I've started learning about X windows by taking the distribution tape for X11R2 and building a system for an HP 9000/350 with an SRX (high speed graphics board for solids rendering). I got it to sorta work but I have a few problems which I hope someone can help me with. * The cursor image is occasionally ``dropped'' onto the display when the real cursor moves on. * The tracking is very slow. When the processor is busy, updates to the cursor position are very intermittent. * The general speed of any graphics operations is slow. * The full 24 bits per pixel isn't supported, only 8 bpp. I think that they are all related to the driver for the 350 SRX. So, does anyone have an improved driver for a 350 SRX that is *quick* and supports the full colour pixels or will I have to wait until HP officially release X11R2 to their customers (to find out if it is any better). Since I'm asking about drivers, is there a driver available for the 319? vic -- Victor Gavin Zengrange Limited vic@zen.co.uk Greenfield Road ..!mcvax!ukc!zen.co.uk!vic Leeds LS9 8DB +44 532 489048 England

Their X11 product (with most of the performance problems and bugs already fixed) may already be out or is due to ship any day. I think it includes support for the displays associated with the 319 (SRX and CH) no matter what 300 SPU you are using. As far as supporting all 24-bits on an SRX, I don't know that it does -- it probably only supports 8 bits. Most folk running X on an SRX have the X environment in the overlay planes, and use Starbase to take advantage of the speed/color of the 24-bit graphics functionality.

On Version 10, you can set up the workstation to either use the foreground planes or the entire SRX graphics space. You can set up both implementations by making screen 0 be the full 24 SRX bits and screen 1 be the 8 bit overlay, switching between the two with the DISPLAY environment variable. If you just want to do easier 3D stuff (no shading or other nifty things) or 2D in an X window, there is a Starbase graphics interface to X provided that works just fine. Version 11 should be out very soon for HP, but you need 6.1 (.2?) of HP-UX to run it, so the beta- release I charmed my salesman out of could not be run. I don't see why HP should mess their X up now, so expect a very good implementation. Now if I can figure out how to make my background color stop being a random color... ****************************************************************************** Tony Burzio * Yeh, so XTERM does a TEK 4014 window, so what?

If those problems existed in the original distribution they may have been fixed in updates. We didn't look for anything beyond 8-bit color maps; just having any Renaissance support was a bonus, since HP (in January) had announced it wouldn't be ready for Release 2. We haven't exercised X11R2 much because the server from MIT sources appears to be too fragile for routine service. We're betting that either the X11R2 product from HP or X11R3 from MIT will be mature enough to adopt, and both are due "any day now". --------------------- Paul Raveling Raveling@vaxb.isi.edu

I seem to recall a firmware bug that caused a similar problem, but that was shortly after it came out. (It may have even been fixed before the official release, I was an internal customer at the time). > * The full 24 bits per pixel isn't supported, only 8 bpp. 8 bpp was the closest match to the existing R2 cfb code; full 24 bit support would have required some real work. > Version 11 is not out yet.

Maybe not out yet from HP, but on the R2 distribution, it looks like there is code there to drive the SRX. (ddx/hp/cfb/ren/*).

You > can set up both implementations by making screen 0 be the full 24 SRX bits This isn't quite true. Our X10 implementation (like our X11) only uses 8 bits of the "image planes". Its does not (nor will our initial X11 server) allow full 24-bit windows. > Version 11 should be out > very soon for HP, but you need 6.1 (.2?) of HP-UX to run it > Tony Burzio * Yeh, so XTERM does a TEK 4014 window, so what? This is true. Our X11 will require HP-UX 6.2. release I charmed my salesman out of could not be run. I don't see why HP should mess their X up now, so expect a very good implementation.
