after running the elementaryOS update which brings the new AppCenter, I found in the update tab a new section "drivers". It offers in my case to install (not update) three drivers: intel-microcode, nvidia-340 and nvidia-375. I have a notebook with intel on-chip-grafic and an external nvidia grafic chip (geforce 840M). So two drivers, one for intel and one for nvidia seems ok but do I really need two drivers for nvidia?
Normally I tend to accept all updates suggested on the update tab, while I am used to choose from the software options presented on the other tab (startpage) for what I think could be useful to me. So I am puzzled, if the new AppCenter offers on the update tab options that are not made for my computer or if it detects my hardware and I should follow the suggestions and install two different drivers for the nvidia-grafic-card?
On the ubuntu help-page I found the information, that I would need for the nvidia geforce 400 to 1000 series the 375 driver (see https://wiki.ubuntuusers.de/Grafikkarten/Nvidia/nvidia/) I did not found any information, that I should install two different drivers. I installed the intel and the nvidia-375 drivers and it seems to work. But still I am puzzled if I need to install the second nvidia-driver, since it is still offered on every system update.
I am running elementary OS 0.4.1 Loki on acer TMP645 with i7-5500U CPU @ 2.40GHz and Intel Corporation Broadwell-U Integrated Graphics (rev 09) NVIDIA Corporation GM108M [GeForce 840M] (rev a2)
