Yeah, I've installed the 'gnome-shell' by the full installation command: pacman -Syu gnome pacman -S gnome-extra and 'gnome-shell' is surely installed. The option "Force Fallback Mode" is OFF as the default. But, the problem haven't gone. The GNOME cannot probe my Graphics, it shows 'Uknown' in 'System info' control-panel. My CPU is Intel i5-2300, with Intel HD 2000 Graphics within it and that's my graphic processor. I've heard about the newest 'xf86-video-intel' can support the Intel's new Sandy Bridge and also HD 2000/3000 Graphics so I installed it. It seems to work fine with xmonad and Fallback Mode of Gnome. Is that driver still under developing and not able to provide Hardware Acceleration? Or just the Gnome don't support it? Or I have chosen the wrong driver? How can I check whether the driver supports 3d hardware acceleration (of course out of Gnome)? ---- Mail by Max Xie On Tue, Aug 23, 2011 at 4:09 PM, Guillaume ALAUX <guillaume@xxxxxxxxxxxxx>wrote: > On 23 August 2011 09:48, Max Xie <max.t.xie@xxxxxxxxx> wrote: > > Hi, > > > > Sorry for my bad English. > > > > I've just bought a new computer about 1 month ago and I tried to install > > archlinux as second OS on it yesterday.
