Enabling mouse on X Server
Hi, I have ported X server on to my reference board based on Intel's Strong Arm, When I connected a USB optical wheel mouse to the USB port the mouse doesn't work: The mouse pointer appears on the screen, dmesg cmd also show that the system has identified the device (including details like manufacturer etc) But the GUI doesn't respond to the mouse. I even tried linking ln -s /dev/usb /dev/mouse but wouldn't work has anyone face this problem and any idea how to locate the issue. Thanks in Advance Regards Suresh

I haven't looked at all of the module interfaces, but here are some thoughts for the two kinds of compatibility: 1) You compile a module with a dynamic-MAXSCREENS server and want to run it on an old X server. There's appears to be no hope here, since the MAXSCREENS variable isn't exported. This may be a detectable case, however, and ELF loader magic might be able to provide a MAXSCREENS set to 16.

In any case, I don't believe this is worth the work or complexity involved. 2) You compile a module with a static-MAXSCREENS server and want to run it on a dynamic-MAXSCREENS server. If the module API passes vectors of "type var[MAXSCREENS]", then that part should work ok, because only a pointer is being passed. If pointers to structures are being passed, and those structures contain elements of "type var[MAXSCREENS]", then the structure sizes will be wrong, so you will not be able to index into a list of structures. Further, elements after var in the struct will be at different locations, so they will not be accessible. I haven't tried to audit all of these cases. The larger problem will be globals that are initialized in the new InitGlobals routine: dixScreenOrigins, savedScreenInfo, screenInfo.screens. I think modules that use these symbols will be expecting the address of the start of the data, but the dynamic-MAXSCREENS server will be providing the address of a pointer to the start of the data (i.e., and will require an extra dereference). ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

If you are running a window manager setting the _NET_WM_PID
property correctly (metacity does it, dunno about others) you can do the
mapping easily. The next example get that prop from the Window ID, and
then converts the PID to the UID of user running the process (it uses
libgtop for doing that):

There has been some work on various window manager projects to tie this information together. For example, in the development code for enlightenment, the direction taken was to tag application windows on launch with their process id as a property. Then the window manager has no trouble retrieving this information at a later time. Would something like that work for you? Or is there some reason you feel it needs to be done at the xfree86 level? -- Kevin ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

how to convert a window ID to a linux process ID?
I need to be able to tell which process a given window was created by. (Window ID=>Process ID) Apparently, X servers don't know which process a client is, they just get a socket (b/c of X's network transparency). It has been suggested that I could run a program like netstat on the client machine(which in my case is the same machine running the server) to get a list of which sockets belong to which processes. Then, I need to get the ID of the foreign socket (socket ID on client end) from which a window was created. What would work well is if the socket ID and the client/window ID could be written to STDOUT or STDIN when the window is created. Then I can have a script read the server's STDOUT or STDIN and compare it to the list of socket IDs and process IDs from netstat on the client machine (which for my purposes is on the same machine as the server). MY PROBLEM: I don't know how to get XFree86 to write the socket ID and client ID when a window is created! Today, I was looking at the XFree86(4.3.0) source code for the first time and trying some different hacks to get the info I wanted to print. In xc/programs/Xserver/dix/dispatch.c, I found ProcCreateWindow and the ClientPtr structure. I was able to get X to print client->index and client->OsPrivate->fd when a new window was created. Which is what I want, except that the client index that is printed is always 2 and the socket ID is always 13. 13 is the ID of the socket that X listens on and I think 2 is the server client? What am I doing wrong? How can I print the Window ID and foreign/from socket ID of a client when a window is created? :) thanx PS: I'm thinking of making a sourceforge project to publish the XFree86 modification and some associated scripts so that others will be able to see which process created which window.
