So far I haven't found any such software, and I am begining to think I may have to write some code myself. Before I ask any questions, I think it would be a good idea to give an overview of my setup. The wall will consist of five PCs and sixteen identical monitors and video cards. It should work as follows: four of the PCs will have four video cards each and will run an X server on each video card, possibly using Xinerama to combine them. The fifth PC will be networked with the four other PCs, will use some mechanism to combine the sixteen remote displays (four if Xinerama is used) into one large display, and will act as a head-end for this display. Matrox sell a pci card with 4 heads http://www.matrox.com/mga/products/g200_mms/home.cfm Stick four of those in one machine and it might solve your problem, as long as the one machine is fast enough. They definitely say you can get 16 heads on one system, although I've never heard anyone do that with Xfree86. These use the G200, not the most recent Matrox chip, but each head has its own chip which makes it easier to drive than the later dualhead chips. -- Dr. Andrew C.

[Xpert]mousemap (was:Getting an additional mouse button to behave like the Alt key)
Hi!
I've recently postest on this list about mapping keyboard events to
mousebuttons.
I've found a small program that does this (it's so small that I've attached
the source, hope that 3kb aren't a problem)
To summarize, the program uses
XGrabButton(disp,
button,
AnyModifier,
DefaultRootWindow(disp),
False,
ButtonPressMask | ButtonReleaseMask,
GrabModeAsync,
GrabModeAsync,
None,
None);
to grab the button(s) and then uses
XNextEvent(disp, event);
in an endless loop to wait for the grabbed mousebutton events.
For simple things, this works fine, but as soon as you push the grabbed
mousebutton, hold it and push a second mousebutton, XNextEvent gets the
second event and everything goes wrong (program crashes, the crash is easily
fixed by a if/continue statement, but the event is lost of course).
So my questions:
- Why does XNextEvent get an event it shouldn't when a grabbed button is
pressed?
- How do you prevent XNextEvent from getting the event or how do you forwared
those events to the X server?
Thanks a lot,
Roland

[Xpert]Geode KDrive
Hello folks. I have a National Semiconductor's Geode XFree86 4 drivers. These drivers can be run in two ways 1) sitting on top of National's Linux Framebuffer drivers and calling acceleration functions (ioctls) provided by the framebuffer drivers. 2) doing all the work themselves. I want to make a TinyX server that uses these accelerated functions. Now, what's my best option: Option A) Hack the kdrive/XFbdev source to call accelerated functions where possible. The rendering functions provided by the Geode driver are: Gal_set_solid_pattern Gal_set_mono_pattern Gal_set_raster_operation Gal_pattern_fill Gal_set_solid_source(unsigned long color Gal_screen_to_screen_blt Gal_screen_to_screen_xblt Gal_bresenham_line There are many other functions available, but since this is going in an embedded device, I'm not too worried about setup issues and much more concerned about how fast the thing is going to draw. Option B) Attempt to figure out what Keith Packard was doing with the other drivers in the kdrive directory, and modify the geode source code to match that. Suggestions/Comments?

[Xpert]Allocated colormaps and 4.2.0
Hi, Having just upgraded to RedHat-7.3 which uses XFree86-4.2.0, I have a question regarding colormaps. I have a colour depth of 8bpp (This is essential for the applications that I want to run, upping the colour depth is not an option) Under the previous version of X (4.0.3 in my case) I had no problems firing up my application or any others in 8 bit mode, now I am finding that regardless of the window manager I use, most colours have already been allocated. For example I have started both mwm (with a plain background and an Xterm) and KDE yet I still get the error cannot allocate colormap entries when starting a colour intensive application. I can see with xcmap that a whole bunch of colours have been grabbed and I would have expected this with KDE, but not mwm or twm. What has been changed under 4.2.0? Am I missing some simple configuration? This didn't used to be a problem and I really don't want to have to end up with colour flashing. My XF86Config file has not changed and neither has my hardware. Any thoughts? TIA, Iain ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

Re: [Xpert]Remote X Server?
Thus spake Dr Andrew C Aitchison: However, you say that XFree86 doesn't support i810e. It does, although you wil need a kernel with agpgart support. The documentation does mention support of i810e boards, but in practice XFree86 3.3.6 (available with Potato) does not support the board - or rather I couldn't do it - even after adding the agpgart module. I tried configuring X using xf86config - the list of supported boards doesn't contain i810 - but no go. I finally managed to start X using generic VGA drivers, which displayed a rather crude X window. I'd XFree86 4.0.2 binary with me, so installed it and upon starting X got the error message: AddScreen/ScreenInit failed on device 0 What could be wrong? As a matter of fact I'd configured X succesfully on the same board, but using RedHat, while this is Debian Potato. Finally I switched over to vesa drivers, and got good clear X. If that didn't work, I was planning to follow Neale's advice and download those packs. -- Cordially, Ajay Shankar P.S: I'm not an Xpert!

[Xpert]adding more keyboards and mice
Hello Xperts, how hard would it be to add more keyboards and mice to XFree, each delivering events to a different screen, thus enabling a full local multiuser setup? Is there any reason why this couldn't be implemented? Vaclav Dvorak [EMAIL PROTECTED] IDAS, s.r.o.http://www.idas.cz ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
[Xpert]monitor redetection
I'm running X (4.2.0) on a laptop, occasionally plugged into an external monitor. If I start X with the built-in display is active and later switch to an external monitor (using the hot-keys), I end up with a 1024x768@60Hz display on a CRT, which is less than optimal. Starting X with the external display active works fine, and displays at 85Hz. Is there a way to kick the server and get it to notice the monitor change, perhaps doing DDC, and change the mode to one with a better refresh rate? I didn't see a way for xvidtune to do this. I also tried writing a simple program to fetch the current modelines (with XF86VidModeGetAllModeLines), update the modeline with appropriate values for an 85Hz refresh rate, and switch modes (with XF86VidModeSwitchToMode), but nothing happened (even though all of the calls succeeded). I'm not sure if adding multiple Modelines to XF86Config-4 will work, since the server appears to discard all but the best modeline for each resolution on startup. Any ideas?

For example I have started both mwm (with a plain background and an Xterm) and KDE yet I still get the error cannot allocate colormap entries when starting a colour intensive application. I can see with xcmap that a whole bunch of colours have been grabbed and I would have expected this with KDE, but not mwm or twm. The RENDER extension grabbed the extra colours.

I know that in X 4.1, the XF86VidMode calls to do this didn't work at all (making a modeline on the fly, adding it, and switching to it): the code was just unfinished. I wrote a patch to fix this but it was buggy and incomplete, so I haven't sent it yet.

Monitor redetection isn't implemented at the moment. If you are happy with what happens when you start X with the external monitor, you could add the monitor ranges from DDC to your config file; running X -configure will probably give you a suitable monitor section. Some laptops allow you to have different refresh rates on the internal and external displays, and some of these are supported by some XFree86 video drivers, which gets around the problem you describe. Monitor redetection could probably be implemented as an addition to the XFree86-VidModeExtension, if anyone felt like it. Laptops would have to be treated specially as many don't report DDC for the internal display. More and more laptops are effectively dual head, and many of them switch active video outputs with hot-keys supported by the BIOS calls which may or may not be documented and available to XFree86. -- Dr. Andrew C.

Re: [Xpert]Xinerama + gtk+1.2 freezes
I have narrowed a bit the bug:
here is a small testcase which very often freezes, but only when in
Xinerama mode and when using a truetype font:
#include stdio.h
#include stdlib.h
#include unistd.h
#include X11/Xlib.h
int main(int argc, char **argv)
{
int i;
GC gc;
XGCValues gcv;
Display *dpy = XOpenDisplay(NULL);
int blackColor = BlackPixel(dpy, DefaultScreen(dpy));
int whiteColor = WhitePixel(dpy, DefaultScreen(dpy));
Window w = XCreateSimpleWindow(dpy, DefaultRootWindow(dpy), 0, 0, 200, 500, 0,
blackColor, blackColor);
XSelectInput(dpy, w, StructureNotifyMask);
XMapWindow(dpy, w);
gcv.font = XLoadFont(dpy,
-misc-yikatu-medium-r-normal-*-*-280-*-*-p-*-iso10646-1);
gc = XCreateGC(dpy, w, GCFont, gcv);
XSetForeground(dpy, gc, whiteColor);
for(;;)
{
XEvent e;
XNextEvent(dpy, e);
if (e.type == MapNotify)
break;
}
for(i = 0; i 50; i++)
XDrawString(dpy, w, gc, i, i * 10, Y a r g l a a !, 16);
XSync(dpy, False);
sleep(1);
return 0;
}
I dunno how to always synchronize operations, so I did an XSync() at the
end and it freezes there. You can retrieve the font here:
ftp://awak.dyndns.org/yikatu.ttf (it's 26k big)
I'm using X4.1.0 from debian/sid
What can I do more to help debug this (very annoying) problem ?

[Xpert]Virtual Screen in 4.2.0
Hello all, Ive been trying to get my XFree 4.2.0 modes setup working without the virtual screen. It seems though that the virtual screen always has the dimensions of the largest mode listed in the display subsection. So, say default mode is 1152x... then I want to switch to 768x... for fullscreen TV, then virtual area is still 1152, which is annoying. How do I change this? thanx in advance, Dietmar ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

Hi, You can't. The X11 specification requires the size of the root window to stay the same for the life of the server. Thank you for your answer. Well, then the specification is kept much more closely in 4.2.0 than it is in 3.3.6, because there I think I had it working smoothly; I might be mistaken though.
