But in this case, gdb does work, the problem is launching gdb from valgrind. Valgrind wants confirmation from me, and I can't give it (i belive it's because X is blocking user input). Also, did you try on the valgrind mailing list? no, not yet. I decided to ask here first, since it appears to be a xfree86 specific problem.

xlib window resizing
hi all, in an xlib app i'm using ResizeRequest events to figure out when the user has changed the window size and then repaint the contents. (the contents of the window are scaled down to fit its current size, something like zoom-in and zoom-out). While playing with the redraw code i noticed that when i resize the window to its original size, the app doesn't receive any ResizeRequest messages. Only expose events are sent, and my app of course doesn't redraw the contents appropiately for the new (original) size is this normal behavior? if yes, which event(s) do i need to listen for in order to know that the window is back to its original size? thanks in advance, ricardo ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
extension opcode list
hi all, anyone knows where i can find the opcodes for X11 extensions? I have a packet trace of an X11 session (running the gimp) from ethereal showing up a bunch of Opcode:211 Unknown Opcode:207 Unknown I tried running xdpyinfo -queryExtensions on the X server but none of these numbers show up in the list. Are the opcodes #defined somewhere, or are they generated dinamically? thanks, ricardo ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

Re: [Xpert]xviddetect
Hi, XFree86 v4 is now a single server, in debian is under /usr/X11R6/bin/XFree86, which supports all video hardware through different modules (see Section Device).. probably the easiest way to figure out which module to load is do XFree86 -configure it will generate a config file (/root/XF86Config.new i believe) for what it was able to autodetect and you can take it from there. hope this helps, ricardo At some point in the past you (savanna [EMAIL PROTECTED]) said: As part of my job, I install Linux on a lot of different machines. I've just moved to Debian Woody, which uses version 4 of XFree86, not version 3 (like Debian Potato). One of the tools I used regularly was xviddetect, to try and work out what video hardware was on the machine. This doesn't appear to come in the version 4 server - is there something similar? I know xf86cfg autodetects hardware, but I'd prefer to get the server right the first time, rather than selecting the vga server, then fixing the server after the install has finished. -- Savanna | Free as in 'free speech', GnuPG Pub Key E40FAE08 | not 'free beer'. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
[Xpert]Opening socket in video driver
Hi again, (I'm appending my previous message as background of what i'm trying to do) My problem now is that i need to open a listening socket to wait for client connections. However, since drivers have limited #include capabilities i can't find a way to get the driver to compile when I add in the socket calls. Looking around I found the libc wrapper, which seems to provide an abstraction layer for many system calls, but socket() is not one of them. So my question is: how much opposition would be to add wrapper functions for socket() and friends (listen, bind, accept, etc)? I'll write the code and submit the patch, but i'd like to know first if this is the right approach (i.e. are there any other hooks in X for doing what I want that I haven't found yet??) and if there's any chance of it getting accepted. thanks, ricardo At some point in the past you (Ricardo Baratto [EMAIL PROTECTED]) said: Hi all, is it possible to write an xfree86 graphics driver that has similar functionality as Xvfb?

Re: [Xpert]Memory allocation code/kernel interfaces? (Resounding Silence!)
Could someone point me in the right direction (e.g., module, file, line, whatever) to find the point at which XFree (or if application the ATI server code) is trying to find a memory range for the display adapter. if i understand correctly, you may be looking for xf86MapPciMem(). If you grep for that inside xfree86/drivers/ati you should have a good starting point.. Also, any documentation or explanation as to the data structures used and the sequence of modules/functions called in initializing the PCI/AGP memory space for the device would be most useful. xfree86/doc/DESIGN has a description of the structure of the drivers, not sure if it has everything you need but it should give you something to start off. It should also be online in xfree86.org and i know there's a pdf version (sorry, don't have the links right now.) JSN good luck, ricardo --- Ricardo A.
