Re: X-Server segfault
I believe this can only happen if your font render is broken. These are fixed fonts. It should be impossible that there is no data in those pointers. Is this recent source code? Yes. static server build from yesterdays cvsup. There have been bugs of this sort fixed in the font renderers not long before 4.3. Though maybe more exist. If this is easily reproducible I suspect you'll find that it only happens with the freetype or xtt renders. It likely is the bitmap renderer, but I'll try without freetype. Is there some way to turn off freetype in a static server (other that recompiling the whole thing with freetype disabled)?

Font data comes from the fontserver. More gdb debugging:

grepping for the FONTGLYPHS macro finds this:
bogomips root /work/xfree86/xc# find -name \*.h | xargs grep FONTGLYPHS
./programs/Xserver/include/dixfontstr.h:#define FONTGLYPHS(font) 0
Huh? How can this ever work? And why it isn't triggered more frequently?

RE: An ATI Mobility M4 driver for laptops soon ?
I have a Dell Inspiron 8000(laptop) 1Ghz 128MB ATI M4 graphics card I am having a strange problem. I believe that this problem is with XFree86 and it's consistency between it's releases for FreeBSD, NetBSD, OpenBSD, Linux. I want to know why some drivers for video cards are not included in all the distributations for all Unix-like operating systems named above ? The XFree86 distributations for each Unix-like operating system contains different drivers for different drivers. For instance, I can configure XFree86 for Linux using the 4.2 series it detects that I have an ATI Mobility M4 and proceeds to configure it. Now when I try this with XFree86 4.2 on FreeBSD, it claims that it can't find the driver and fails to configure at all. Who do I contact to have the ATI Mobility M4 driver included with all XFree86 distros for NetBSD, FreeBSD, OpenBSD and Linux ? -Thanks Kevin Marshfield
RE: An ATI Mobility M4 driver for laptops soon ?
the standard r128 driver should work for this chipset. the M4 is r128 based.

Make install blows away startup files?
Hi Guys, I have been mass compiling and installing multiple versions of XFree86 onto a machine for compatibility testing (Red Hat 7.3 based, so I can use the GDB hacked up debugger ;-). However whenever I do a 'make install' from a freshly built 4.2.0, 4.2.1 or 4.3.0 (haven't done any ealier versions yet ;-), it always blows away something in the startup files so when I do a 'startx', all I get is a desktop with three console windows open (seems to be using twm as the window manager). If I copy all the files from the original Red Hat 7.3 /etc/X11 directory across, it starts up just fine using the GNOME desktop. Firstly, I don't know what file is being destroyed or replaced. Does anyone know what file is getting replaced? Secondly it seems to me that a 'make install' should be non-destructive and should not be changing this file. I have not changed any of the defaults in the host.def file, so it seems to me that it is bug that after a make install over the top of an existing XFree86 install, XFree86 no longer functions the way it did before. Is there an option to fix this in the host.def file? If so, perhaps this should be the default option when doing a make install?? BTW, I am using a script to symlink /usr/X11R6 and /etc/X11 for each version so I can switch between all versions with a simple command ;-) Regards, --- Kendall Bennett Chief Executive Officer SciTech Software, Inc.

Yes it is an option, though I do not recall which one.
