well that might be a work arround for Optimus. I on the other hand have GT 730 i just bought. inserted it into the computer, booted to low resolution in nouveau drivers. added Xorg edgers PPA to be able to install nvidia 340. and it should all work (just liek it did for many people with similar card on forums), right? wrong - when i get to desktop all i get is blank screen (can see the VESA splash with dots under Kubuntu before that). Card is recognised only as Nvidia Corporation Device. there is no chip or anything like that. Xorg.log shows that GPU failed to initialize. It also can not find "screens"
i've also found this in one of the logs i went through yesterday: "API mismatch: the client has the version 340.76, but this kernel module has the version 331.113. " same happens when using version 346. I can not get to desktop basically ot be able to use nvidia settings. when driver get's installed nvidia-settings is emtpy. there is no devices in it. ofcoruse upon reboto there is blank screen so i can't say what is in it then. I am also not sure why bb switch and things like that are being installed if i only have one GPU in the motherboard. though i should mention that the motherboard has two slots (PCIe (@ 4x) and AGP). At the moment i am using very old Radeon and foss driver there works and finds correct screen resolution (1650x1050) well. But it is crashing when running some games, so i wanted to replace it with nvidia only to be met by dissapointment and very poor nvidia linux support. Xorg-edgers ppa gives me 640x840 screen resolution and works very very slow.
