Dear meintainers, I ŕan into an issue with optimus and an nvidia card. Fist the hardware:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (re v 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev ff) I have two graphics cards, and the nvidia card is NVS 4200Ḿ. Please note, that the package nvidia-settings and the description of the package "nvidia-legacy- *-390xx" is telling, that these are the drivers for this graphic chip. But these are NOT! After hours of testing with buḿblee and then examine the NVidia site, I disćovered, that the correct driver for thius chip is *-340xx NOT *-390xx. Installing this version, everything is working perfectly. And to confirm: Also the NVIDIA website is telling, for chipset GF119 == NVS4200, thew correct driver is 340xx. Just before other people step into this trap, maybe you might want to correct the description. Thanks for reading this, hope, I could help. Best regards Hans
