which makes for a second question for the group. I know with the 0.7.3/4 drives you have close to hot swap abilities. (Once you replug you need to ctrl+alt+f1, then ctrl+alt+f7 to get the tablet working again.) If there anyway to automate that process? From what I saw in the mails on that patch there is a signal sent when you swap back into X that causes the tablet to be redetected. Is there a command you can run to manually make that signal be sent? (If so I'd imagine it would be trivial to write a script that watches for the tablet to be connected and then send it (say by using hotplug?)) I'm just not sure if there is a way/how to send it.
Thanks

I'd personally say it sounds like a great idea. I'm going to give that module of yours a test and see if I can use it for the workstations at my work. (We have 200+ Linux machines with tablets, many of the people here have two workstations - So if we could get the tablets to hotswap we could potentially give everybody usb kvms and halve the number of tablets we need to have. (Right now a lot of them have two or even three tablets o_O;;;))On 6/21/06, Magnus Vigerlöf < [EMAIL PROTECTED]> wrote:Hi,
I'd like to have som input from you about an idea I got a few weeks ago. What
I'm most interested in is if it has been tried before, serious drawbacks you
can see, .... But any comment is appreciated. I have not seen anything like
this beeing tried/developed before but I might be wrong.
My problem was that I could not unplug/plug my Wacom tablet, without getting a
kernel oops (even though I tried all trix I could find on the linuxwacom-web
and other sites), or only getting my tablet in a 'glorified-mouse-mode' where
screen edges never are alligned with the tablet edges and there's no pressure
sensitive information sent.
The idea is to create a module that provides an aggregated device for tablets,
very much like /dev/input/mice is for all connected mice. A device that X can
open even though the tablet is not connected and which automatically detectes
if I plug in my wacom and in that moment open it so it can forwarde events to
those who has it open.
Pros/cons I've seen this far:
+ No special handling when I unplug/plug the device for X.
+ No requirement to have the tablet plugged when X starts.
+ Device id (pen/eraser/...) should still work.
? Absolute coordinates must be recalculated to the virtual tablet values (all
tablets has different max-value for x, y, pressure, etc)
- Probably strange result if several tablets are connected at the same time.
More information can be found in my initial post about this:

I've also made an implementation of the idea that you can test if you are
interested in it: http://195.38.3.2/linuxprojs/ (updated 2006-06-20)
