** Description changed: - Older Sony Vaios have 2 graphics adapters, usually one from Intel and - one from nVidia (e.g. on the Vaio SZ650N, there is an Intel GM965 and an - nVidia GeForce 8400M GS), which you can select with a hardware switch - when the notebook is off. + Some older Sony Vaios have 2 graphics adapters, usually one from Intel + and one from nVidia (e.g. on the Vaio SZ650N, there is an Intel GM965 + and an nVidia GeForce 8400M GS), which you can select with a hardware + switch when the notebook is off: so-called STAMINA and SPEED modes. Ubuntu supports acceleration of both chips with open source (Intel) and proprietary (nvidia) drivers, but installing both means that the 3D setup gets clobbered. The current workaround is to have two xorg.conf files, one for each adapter, a couple of backed-up 3D libraries and a script that selects the right combination. The script in its current state is specific to particular nvidia driver versions (even a minor - version change would break it), so is limited, but does work, at least - on Hardy (Jaunty is proving more difficult to configure). + version change would break it), so is limited, but does work. + + Jaunty is slightly more difficult to configure than Hardy as installing + nvidia-glx-180 removes /usr/lib/libGL.so.1.2 (needed for the Intel 965), + which is not replaced by simply reinstalling the deb for libgl1-mesa- + glx.
