So i try to get the archive for the commit

git archive -o repo.tar --remote=git://anongit.freedesktop.org/xorg/driver/xf86-video-intel 2851b7747bc8e143aa5c6209b8800eeccb629058

fatal: remote error: access denied or repository not exported: /xorg/driver/xf86-video-intel


Then i try to set the remote url but..

git remote set-url origin git://anongit.freedesktop.org/xorg/driver/xf86-video-intel

fatal: Not a git repository (or any of the parent directories): .git
