[XFree86] framebuffer and Xfbdev( urgent )

[Liu, Nian(Neo)]

Hi, folks   i'm responsible for researching the possibility to implement semi-transparency in X and must have a quick conclusiong before this Friday. since i'm quite a newbie in the field, here i ask for your valuable help on:   1)who is responsible for window rendering? Xfbdev or something else 2)if it's Xfbdev, has anybody cracked it to impelment any feature such as semi-transparency or non-focus window dimming out?   i just know DirecrFB have excellent implementation on transparency among windows and have no time to dig the source code in such limited time.   great thanks in advance and best regards,   ln
