Description markm 2011-03-30 12:27:04 UTC

Description of problem:

Very poor performance compared to Gnome 2.32+Compiz on Dell d430 laptop (Core 2 duo 1.33GHz processor, 2GB ram, intel graphics).

It gets worse, when I connect the secondary monitor - desktop becomes unbearably slow and stops responding after a while.

Version-Release number of selected component (if applicable):

gnome-shell-2.91.92-3.fc15.x86_64

How reproducible:

always

Can you provide details of "Intel graphics" - that could cover a very wide range of different chipsets.

It's Intel 945GM Chipset (from dmesg), I think it's similar / related to this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=582861

Sadly, a GM945 can't do accelerated 3D across 2 monitors. There might be something else going on in the single-head case, but it's hard to tell.

that explains a lot... in Fedora 14 compiz basically stopped working, though it was possible to switch back to metacity. not sure how I can change it with gnome-shell, as it basically tries to composite in 3D both internal and external screens... there should be either switch to the fall back mode or notice in Display preference window.
