Intuos4 on centos5 fails to create device in time

Hello
I was wondering if anyone else had seen this. version 0.8.4-3 kernel 2.6.18-128 on boot, with the wacom connected, the /dev/input/wacom device is not created until after the X server has started, causing errors in Xorg log file. If you immediately issue a ctrl-Alt-Bksp it works as expected. I thought I may be able to roughly work around this by using wdaemon or wacomproxy but they both don't look to support intuos4. I will get more details soon Grant ------------------------------------------------------------------------------ Come build with us!

If you immediately issue a ctrl-Alt-Bksp it works as expected. When I plug in a Intuos2 it works without issue. it even works in the graphical boot screen albeit in relative mode. I plug in the intuos 4 and I get nothing on the boot screen and the login screen is barely working only moves on pendown+drag. I hit ctrl-Alt-Backsp and it works. bleow are exerpts from the xorg log file of not working and working > > I thought I may be able to roughly work around this by using wdaemon or > wacomproxy but they both don't look to support intuos4.

I don't think either is updated, at least they are not for updated for I4. You may contact with the authors. Or you can add I4 to the application yourself if you know how to write C program. Working log entries As I mentioned above, wacom.ko is not loaded when system starts. So /dev/input/wacom is not available yet. I bet if you "ls /dev/input", you don't see wacom in the output.

Essentially the udev event is not being triggered untill the last moment which is too late. Why wouldn't the module be loaded until then?

As mentioned the device is created after the xorg server starts when udevd gets the event. I can't test this as by the time I'm able to log in it is already there Grant ------------------------------------------------------------------------------ Come build with us!

I don't think the author of wacomproxy is still updating it. There are however other people still hacking around with it. If you check the tracker for wacomproxy (http://sourceforge.net/tracker/index.php?func=detail&aid=2786587&group_id=184413&atid=909158) there is a patch for I4 support available. Adding new tablet support to wacomproxy is actually fairly simple for the most part, if you read the source code comments a lot of it is copying and pasting sections of code from the linuxwacom source tree. I made my own I4 patch for wacomproxy independantly for use at my work before noticing the one uploaded to the website. Incidentally some of the admins at my work also managed to make a patch to make wacomproxy work with kernel 2.6.29 which I think we could release if anybody particular wanted it. (I've not really looked into it at this point since outside my work I've not heard of any interest for wacomproxy on newer kernels.) I can't speak for wdaemon as I've never used it. -J ------------------------------------------------------------------------------ Come build with us!

I dont really see a use for such things any more. Newer Xorgs all
support DBUS configuration. I've writen my own X hotplug daemon, that when run tries to remove anything added automatically and then scans for wacom device nodes and adds all devices it finds. This includes any USB serial adapter using serial tablets I have. It also listens to dbus for any notifications of plugged in tablets and if I so desire I can also make it scan for new devices when I hotplug my USB serial adapter and effectively have a fully hotpluggable serial tablet. Hacking this up took me one or two evenings. If you wanna use it, heres the python code: http://sourceforge.net/projects/watahod/develop/ It does presume its own udev file. -- --Alexia ------------------------------------------------------------------------------ Come build with us!
