To my surprise it seems a different issue than treated on this forum, I had a look at several post including Ubuntu and ASUS G750JM, GTX860M / Nvidia problems (by adding the repo, no new available driver appears) and the help https://help.ubuntu.com/community/BinaryDriverHowto.

I have a nvidia graphic card, the sticker tells me it is a Geforce 310M cuda 1 GB (and I can see it in windows).

Symptoms:

  • All webpages with google maps are very slow.
  • The output of lshw (see below) does not mention Nvidia at all.

Context information (I am not sure which is relevant and which irrelevant): System: Xubuntu 18.04 Laptop: Asus K52JC

I am looking for a prudent (and if possible pedagogical) approach to resolve it.

  • The command you used does not show all graphics cards, it shows only the iGPU, which is the one you're currently using. Please open Software & Updates > Additional Drivers. It should show up there. Select and apply the recommended proprietary driver. Reboot. Disable Secure Boot in UEFI as it prevents loading the Nvidia drivers even if correctly installed. Then you should be able to switch to the Nvidia graphics using Nvidia X Server Settings app (reboot required). – GabrielaGarcia Jun 5 at 14:06
  • In Software & Updates > Additional Drivers it only says "No additional drivers available." – WhiteHorse Jun 5 at 16:16
  • Then please check your UEFI settings as it may be disabled there. Some have settings like iGPU, dGPU and Auto (you want Auto). – GabrielaGarcia Jun 5 at 16:18
  • And hopefully it's just that. If you installed in Legacy mode it the switchable graphics feature probably won't work. – GabrielaGarcia Jun 5 at 16:21
