Software Rendering for GNOME Shell
The GNOME Shell experience is now available on all hardware, including those using software rendering. Users still wishing to use GNOME's fallback mode can enable it manually by accessing the System Info control panel applet, selecting Graphics, and setting the Forced Fallback Mode option to ON.
The X server and libraries in Fedora 17 support version 2.2 of the XInput extension, this includes multi-touch support. Applications that choose to will now be able to take advantage of multi-touch support on Fedora.
Smooth Scrolling Support
The updated X server also provides smooth scrolling for drivers, and devices, that support it. Scroll data is now exported as axis values in addition to the legacy button press events. This allows applications to take velocity into account and provide a smoother scrolling experience. Like multitouch, to take advantage of smooth scrolling support for it must also be actively written into the client application itself.
The i810, mga, r128, savage, sis, tdfx, and unichrome DRI drivers are no longer supplied, as they are no longer included by Mesa. Impacted hardware includes variants of the following devices:
- Intel i810 and i815 motherboard chipsets
- Matrox MGA G200, G400, G450 and G550 cards
- ATI Rage 128 cards
- S3 Savage 3D and Savage 4 cards
- SiS 300, 540, 630, and 730 chipsets
- 3dfx Voodoo 3, Voodoo 4, and Voodoo 5 cards
- VIA Unichrome and Unichrome Pro chipsets
This hardware is now supported by the llvmpipe software 3D driver which, unlike the older DRI drivers, exposes OpenGL 2.x functionality.
