I would think this requires a custom daemon of some sort.

The general answer to this is yes. But I dont know the specifics of
the pam_usb module.  Pam lets you stack modules, even the same one
multiple times, with different options.

Subject: SGI Indigo2 and 19-in CRT

I've got an old SGI Indigo2 and huge 19" monitor that I'd like to give away to a good home. It ran the last time I
fired it up a year or so ago. It's got a recent version of IRIX, 150 MHz MIPS processor, 2GB of HD, and the
coolest screen saver you're ever seen (Electropaint). I don't recall much more about the specs, but it's
kind of fun to play with. No delivery. Pick up in Blaine only.

Visible click in X ?

Is there an easy way to intercept mouse-click events before they hit
the window manager?  I use kmousetool to help stave off repetitive
stress injuries (it auto-clicks when you pause the mouse for a given
interval, and starts a drag event if you move the mouse within another
given interval after the click), and it's difficult to hit that short
drag interval when trying to pinpoint things like window borders,
small toolbar/panel drag handles, etc.

What I'm really after is a visual indicator that the mouse was
clicked,  preferably something relatively unobtrusive, like a slight
cursor change.  I'd like to have a solution that doesn't depend on any
given window manager, since I'm always playing around in different
ones.   My target box is running Ubuntu, so something already sitting
in the apt repositories would be ideal.

Any help/info/suggestions would be appreciated.

Thanks,
SM

No.  X Spec only allows one window to receive a button press event.

Are you after something to work outside of kmousetool, or just in conjunction with it?  If you want it to work with it, the simplest thing would be to get kmousetool to use the kde system bell or some similar mechanism.

USB to Serial adapter

Good Morning,

Has anyone used a USB to DB9 serial converter?  This model or similar


Is there any other (cheaper!) you'd care to recommend. Are any special drivers or modules required?  Is "Hotplug" sufficient?

Thanks

I know the ones we use at my work (a Belkin single-port adapter)
require special drivers for Windows, that create a virtual COM port.
Unfortunately I do not know if they work under Linux.

RE: USB to Serial adapter

We use ones from ATEN (http://www.aten.com/products/productItem.php?pcid=20050107104554001&psid=20050117102915002&pid=2005022316346005).  They work flawlessly on Fedora Core 4 without any extra drivers or modules, however in Windows you do need a driver.

I just purchased the cheapest piece of junk I could find on eBay (it was 
like $2 + $3 shipping or something); works great.  :)

When you guys say it works great, does that include working on linux -
just like a native serial port?

Or are we talking windows only here?
