Yeah, it's a shame that support was removed (via a driver rewrite which ignores the PT) in recent kernel builds. Otherwise, I was going to add it at the same time. > The only catch is that the drawing output > lags the tablet strokes by quite a bit.

The mouse events go at a higher priority than the expose events, so the screen update waits until you stop moving if it gets behind. But, at the end your entire stroke should appear. I would be concerned about reducing the update rate, it might lead to less accurate drawing. I've got some optimizations planned to the C module which should make it better, and I think there are some bottenecks in the X server that slow things down and could be fixed, but my recommendation for now is to draw slower :) > Great job and many thanks, Wade!

I'd like to see the next OLPC Software Release contain the wacom drivers. It would especially help activity developers prepare for XO-2. BTW, Colors! version 11 did not appear to have > the photo snap capability. Was that removed? See Nirav's response. I'm also planning to add Paste support so you can just snap the photo in Record (or whatever) and paste it into the Reference image, then paint over that. Best regards, Wade
