Hi, great it works. I now have a working stamina-speed switch and right now I'm running on the Nvidia chip, with latest Nvidia drivers. I've done nothiing else, than install a stock 11.04. When I boot with the switch in stamina mode, I get the colorfull vertical lines, so I can't see the Grub menu, but Ubuntu starts just fine. "glxinfo | grep rendere" reports: "OpenGL renderer string: GeForce 9300M GS/PCI/SSE2" This has until now always reported the Intel chip....wuuuhuuu.... As others have reported, brightness buttons no longer work though. My model is the Vaio VGN-Z21WN _______________________________________________ Mailing list: https://launchpad.net/~sony-vaio-z-series Post to : [email protected] Unsubscribe : https://launchpad.net/~sony-vaio-z-series More help : https://help.launchpad.net/ListHelp
