thinkpad r60i 0657LHC显卡驱动似乎自己安装的不正确！

xf3i

xf3i@debian:~$ glxinfo |grep vendor
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Mesa project: www.mesa3d.org

name of display: :0.0
display: :0  screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.2
为甚么是 No (direct rendering)
