hi there, first post on this list :)


i installed fedora9 preview on my lenovo thinkpad x60
the gfx chip is an intel "i945GM"
i've found when i run compiz X gets rendered all white.. i can't see a
thing.. but i can guess it's still working though:

I've got a similar result with my Macbook 2,1 (blackbook) which has the Intel GMA 950 chipset. However I have a little difference below...

 cube and scale plugin seem to respond, so i can see a white cube on a
slightly darkened white desktop ;)
.. same for "scale plugin, i see background that get darkened a bit..

Yep all the plugins and window motion, keybindings, etc, work just fine while the screen is all white.

i've figured if i install fusion-icon and choose "indirect rendering"
setting,
 my desktop is being rendered correctly :)
that's the good news.. so i can use compiz on my laptop.
it's working through that "indirect rendering option though.

Indirect Rendering does not work for me when I install fusion-icon or compiz-fusion (either from the external repo [1] or directly from rawhide). The problem seems to be the failure to acquire TTM support. I've meant to get his one bugzilla'd.

The error I see is:
Failed to initialize TTM buffer manager.  Falling back to classic.

Its apparently reported all over the place with intel chips if you google TTM buffer manager. One report is at [2].

Compiz works, compiz-fusion does not. If I start up the super-basic compiz functionality using the 'Enable Desktop Effects' dialog I can use compiz with the cube, wobbly windows, and I have Direct Rendering enabled. I can run 3d games (mostly) although occasionally compiz will turn all white again.

i was wondering why i had to use that indirect rendering option, and if i
can get rid of it ?
i tryed adding "i915.modeset=1" in my grub.conf,

i can report new resolution available, fast vt switching, no problem with
font rendering, and things being a bit slower than before.. it seems stable,
and it didn't helped with my problem of X being rendered all white and me
having to set "indirect rendering" .. kernel mode setting looks very
promising though :)

hum.. anyone can see a solution about my X being rendered all white and
indirect rendering option problem ?

I'd suggest doing 'yum remove compiz-fusion' and then trying to just use the Desktop Effects. I didn't even get as far as you with fusion because indirect rendering and loose binding both still cause the screen to go full white. I can even still type in the terminals I had on my desktop while its white, to quit fusion or start metacity, so its not crashing X its just displaying full brightness (for all but the mouse cursor which I can still see move).
