I'm using awesome as window manager for a small surf&info terminal. Chromium is started directly after login on the first workspace and should be displayed fullscreen. I've set the layout of all workspaces to awful.layout.suit.max and followed Awesome FAQ so that Chromium and all other (automatically) started programs will be shown on the right workspace. All programs except Chromium will start correctly in fullscreen mode.

I tried

{ rule = { class = "chromium-browser" },  
    properties = {floating = false, tag = tags[1][1]}}

and

{ rule = { class = "chromium-browser" },  properties = {tag = tags[1][1]}}

but Chromium will always start in floating mode. This is a bit annoying as you still see awesome's panel at the top.
