Enrico Zini sez: } Hello, } } I've been asked to build a nice kiosk with a dual-head machine, and I'm } having difficulties with a couple of issues. } } The kiosk: } } - One head, the normal monitor, will be used by users to browse a website. } - The other head, a TV screen, will continuously show a fancy display } of updating data, composed by a Galeon fullscreen window with a } complex webpage full of java applets, reloading pages and stuff.
You don't want Xinerama. You are using the two heads as separate displays. } The system so far is based on an updated Debian testing distribution. } It works, dual head works, window positioning with --geometry usually } works, we've prepared everything to run in a diskless system from a live } CD, everybody is happy and excited, except for a couple of issues we } can't solve cleanly: } } - I need to place a full screen Galeon window in the second head. } Galeon ignores positioning with the --geometry switch (it only obeys } window size indications). So far, the only way I've found to make it } go there is to write some sawfish lisp code. } Is there a better way to do that? Use mozilla, which does honor --geometry? Muck with the Galeon source to make it use the particular size and placement you want? } - I need to restrict mouse cursor movement so that the user can never } move it out of the first head and mess with the TV screen. } Even better could be to restrict the mouse cursor so that it never } moves out of the maximized galeon window in the first head. } How do I do that? This is where you don't want Xinerama. If you run a single X process with two screens but without Xinerama, only the pointer can move between screens. I don't know of a good way to prevent the cursor from crossing screens. You might be able to do it with some x2x trickery. It is also possible to write a simple X program with an invisible window over the forbidden screen which warps the pointer back to the other screen. See XWarpPointer. } - I've managed to disable X killing trough C-A-Backspace. How do I } disable vt switching (C-A-F<n>)? Much as the X killing is disabled with DontZap, vt switching is disabled with DontVTSwitch. } Bye, } Enrico --Greg -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
