Hi, To enable the Xorg compositing extension with plain fluxbox (no DE), and be able to use true transparency, I'm using compton (I've used xcompmgr with worse results), but I experience some problems: 1.- At times, though fluxbox is still up and running, it stops managing the non GTK/QT applications, such xterm or rxvt-unicode. The only way to get fluxbox to start controlling them again is through a fluxbox restart. 2.- At times, when restarting fluxbox due to [1], the X session dies, and a new login is required. As I said, with xcompmgr the problems show up more often, both [1] and [2]. That's why I keep using compton. Any idea on how to avoid these problems? In case, I'm calling compton in my ~/.xinitrc, prior to calling startfluxbox, like this: compton -bc -o 0.22 -m 0.88 & I'm not having any particular Xorg configuration to enable compositing. Some fluxbox setting to take advantage of transparency: session.screen0.menu.alpha: 210 session.screen0.slit.alpha: 210 session.screen0.window.unfocus.alpha: 215 session.screen0.toolbar.alpha: 210 For rxvt-unicode: URxvt*.depth: 32 URxvt*.background: [88]#000000 And for conky: own_window_argb_visual = true, own_window_transparent = true, Don't think those settings will help anything, but just in case... Thanks, -- Javier
