Unity lost the 2D failback feature

[Paolo Sammicheli]

Binary package hint: unity

Maverick had a failback process which shown an alert and loaded a gnome desktop when no 3D driver is available, as described in bug 614088

Booting with Natty Alpha1 you get simply the Maverick wallpaper: no pop up message, no menu bars.

I'm also testing the Alpha1 i386 iso and the desktop is now totally unusable for me unless I create a launcher for gnome-terminal and work from there. The 11/29 daily would still default to "no effects" and at least be usable, now it is not!

My hardware:

Intel Atom 230 CPU @ 1.60GHz
System Memory 2GB DIMM
Intel 82945G/GZ Integrated Graphics
Intel N10/ICH 7 Family High Def Audio Controller

I've noticed for some time that desktop effects default to "none" testing natty whereas it normally defaults to "normal".

I also noticed this one a kvm virtual machine.

This will be implemented for alpha2, see https://wiki.ubuntu.com/NattyNarwhal/TechnicalOverview

AMD Athlon XP 2000+ 2GB RAM nVidia NV34 GeForce FX5200, Sis 741Gx chipset motherboard. I get no menu panel top or bottom just the wallpaper and examples/install icons and a pop-up saying there are restricted drivers to install.

[Didier Roche-Tolomelli (didrocks)]

Ok, let's get a workaround for Alpha1 just in case you don't have 3D support (the release team hacked this).

/!\ this doesn't fix the case where you have selected "no effect" in the gnome-display-properties before the upgrade.
