[Intrepid] Compiz causes >20s hang/delay after login

[roots]

Binary package hint: compiz

hi there,

upgraded to intrepid 2 days ago via fresh install, now on every login with compiz enabled i do get a >20s hang/delay before my desktop is ready. during that time, first only the brown desktop-b/g is shown, loading-watch is ticking, then after 2..3s only my desktop wallpaper appears and the loading-watch is not ticking anymore. after another ~20s finally all other desktop elements appear and my desktop is responsive.

on hardy the whole login process took approx. 3..5s (see my specs to explain this). i disabled compiz to check and found that metacity is available almost instantly after logon. in compiz i mainly use expo/viewport switcher without additional eye candy. but even if i reduce compiz settings to an absolute minimum the delay persists.

my sys/specs:

ubuntu hardy 8.10 (updates as of 11/07/08)
compiz 1:0.7.8-0ubuntu4.1
nvidia 177.80 drivers

intel e8500
gforce 280gtx
4gb ddr2-800
2x ssd mtron 7535 raid0 @ areca 1210

a small correction: in the first 'stage', the d/t background is not (ubuntu)brown but black, so i assume no b/g whatsoever is loaded.

another correction and a 'sorry' for the seesaw...in the first 'stage' there is _no_ loading-watch, just a plain white cursor arrow on a black screen.
