Arch on a Lenovo P52 is an amazing combination.
Before you begin: There are some possible "BIOS BRICKING" settings. The settings are not directly related to installing Arch, but most Arch users will make configuration changes in the same areas where these settings can be modified. So I'm offering this warning here.
Make sure to update your BIOS to V1.17 or later current is v1.24 as of March 2019. Earlier versions of the BIOS may become inoperable if you select certain settings:

Note: You can update the BIOS using the bootable (CD) update option from Lenovo, or just update the BIOS using the pre-packaged Windows installation and software and then continue with Arch installation once the BIOS is updated.
Follow the Beginner's guide to install Arch.

This laptop has its external display ports directly wired to the NVIDIA chip. In loose terms this means that the dedicated GPU must be enabled in order for external displays to be used. Luckily, it is possible to do dynamic switching between the integrated and dedicated graphics, but this is only possible by using the Intel DDX driver as opposed to modesetting.
The laptop can be used in one of two modes: Hybrid Graphics, or Dedicated Graphics only.
In order to use the integrated Intel UHD 630 GPU (as part of Hybrid Graphics) you need to add the
i915 module to your
initramfs by adding it as a module in your mkinitcpio. This is done by setting the following on
Failure to add the above will leave you stuck when trying to load the
initramfs and your system won't be able to boot.
It might be possible to make do without the module above by using the
Dedicated Graphics only (this can be done by changing the setting in UEFI).
Proprietary driver with bumblebee
With this setup the integrated GPU is used by default but some applications can be rendered on the discrete GPU with the
primusrun launchers. See Bumblebee for detailed instructions. The lack of proper v-sync support means that with this method applications rendered on the discrete GPU exhibit tearing. There is also some overhead introduced as a result of moving data inefficiently between the discrete and integrated GPUs, but the Nvidia GPU performs much better than it does with Nouveau.
To get this working you'll need
Then set the following configuration files.
Section "ServerLayout" Identifier "Layout0" Screen 0 "intel" Inactive "nvidia" EndSection Section "Monitor" Identifier "Monitor0" Option "DPMS" EndSection Section "Device" Identifier "nvidia" Driver "dummy" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" EndSection Section "Screen" Identifier "intel" Device "intel" Monitor "Monitor0" EndSection Section "Device" Identifier "intel" Driver "intel" Option "TearFree" "true" Option "DRI" "3" BusId "PCI:0:2:0" EndSection
(you probably already have one of these so adjust/add as needed - the dummy device at the end is essential!!):
Section "ServerLayout" Identifier "Layout0" Option "AutoAddDevices" "false" Option "AutoAddGPU" "false" # Inventions Screen 0 "nvidia" Inactive "intel" EndSection Section "Device" Identifier "DiscreteNvidia" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "PCI:1:0:0" Option "ProbeAllGpus" "false" Option "NoLogo" "true" Option "UseEDID" "true" Option "AllowEmptyInitialConfiguration" EndSection Section "Device" Identifier "intel" Driver "dummy" BusID "PCI:0:2:0" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" EndSection
At this stage, restart your machine. Then you should be able to run applications on the GPU as you normally would with
optirun glxgears. If you want to use the external displays you need to keep your GPU on by running an app on
optirun and then running
intel-virtual-output -f (this will stay running and binds the external display ports to virtual outputs that you can use). At this stage you should be able to see and use the external ports.
Every once in a while Linux kernel upgrades will cause issues where the Touchpad and Trackpoint stop working. Booting with kernel parameter
psmouse.elantech_smbus=0 seems to fix it. FS#59714#comment174924
