Pe4enko: Here is your problem: NVRM: API mismatch: the client has the version 410.66, but NVRM: this kernel module has the version 390.87. Please NVRM: make sure that this kernel module and all NVIDIA driver NVRM: components have the same version.
It looks like you installed the 410.66 driver (maybe using the installer from Nvidia's website), and then tried to install the 390 driver from the Ubuntu archive. This is not going to work. Please uninstall the nvidia packages (sudo apt-get remove --purge '*nvidia*') and then use the Nvidia installer to uninstall the other driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778011 Title: SRU: PRIME Power Saving mode draws too much power To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1778011/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
