Nor an additional-drivers app in the menu, nor such a program (checked by locate), nor such an installable package (checked by apt-cache search). In 12.04, I have neither an additional-drivers tab in update-manager: How to switch the one being used? Re: additional-drivers Parm: NVreg_InitializeSystemMemoryAllocations:intĮRROR: modinfo: could not find module to find out which one is being used? Vermagic: 3.11.0-26-generic SMP mod_unload modversions 686 Modinfo knows about several nvidia drivers installed in the system ( nvidia_173 and nvidia_331), but lsmod just calls it nvidia (and modinfo nvidia fails): $ modinfo nv I'm trying to find out which Nvidia driver is being used currently in the system (and how to perhaps switch it to another version or the open-source nouveau driver).
