Current hacks for my Lenovo Thinkpad P71

Thinkpad P71 hacks

A collection of hacks to make my P71 more usefull.

Let me know if you get your fingerprint sensor working.

Setup

My particular P71 has the 17" 4k 3840x2160 display and an nvidia GPU.

I've set performance mode to disable the onboard intel gpu which causes issues with brigtness keys that are fixed below.

I'm currently using ubuntu 17.10 with ubuntu-studio (a loaded xfce variant) with the nvidia priorietary drivers.

Defaults use xrandr and screenlock scrambles the order of metamodes. It's most useful then to take over control of display toggles and use nvidia-settings -a CurrentMetaMode to directly toggle modes.

brightness.sh

Allows toggling brighness of displays that do not support xbacklight via xrandr.

Assumes external display is on DP-3.1.

USED IN Keycodes Ctrl+XF86MonBrightness[Up|Down] (xfce)

/home/rferguson/code/scripts/brightness.sh -inc 5
/home/rferguson/code/scripts/brightness.sh -dec 5

Tied to Ctrl+XF86MonBrightness[Down|Up] to toggle external display brightness.

Note

The P71 backlight keys are broken when in xorg when the intel GPU is disabled. This is fixed by tying the keycodes to xbacklight.

Keycodes XF86MonBrightness[Up|Down] (xfce)

/usr/bin/xbacklight -inc 10
/usr/bin/xbacklight -dec 10

nv-metamode-toggle.py

Allows toggling nvidia metamodes as defined in xorg.conf.

Usage:

nv-metamode-toggle.py       # Prints index: mode list.
nv-metamode-toggle.py indx  # Sets metamode to index.
nv-metamode-toggle.py n     # Toggles metamode to current + 1

I still haven't tamed the xsession startups tendency to pick it's own resolution so I have a startup command to reset it back to what I want for an initial mode on starup.

sh -c "sleep 4; /home/rferguson/code/scripts/nv-metamode-toggle.py 1"

grub toggle for reasonable console size

Note that fb resolutions for console don't work the same when not using uefi boot.

Note: If you find settings you prefer either via xrandr or nvidia-setting, you can find the metamode via nvidia-settings -q CurrentMetaMode and add that to the semicolon delimited metamodes string in xorg.conf.

# Current xorg.conf Ubuntu 17.10 ubuntu studio / xfce on a P71 with 3840x2160 HD internal LCD on 
# DFP-4 and Acer CB280HK on DFP-3.1 also 3860x2160.
#
# Viewport settings allows smaller laptop display to render objects at nearly identical size.

Using nvidia without disabling the intel gpu

If you do not want to be locked into using the nvidia GPU or want to use the intel for maybe some alternate screen, you can back out the performance mode setting in bios and try to merge in some of the work in the xorg.conf files found in the prime-select repo.

https://github.com/wildtruc/nvidia-prime-select

This might be something I look into later to give myself better battery life on the road.

efi

The EFI files need to be on a vfat filesystem.

disks

Linux is on nvme0n1 and nvme1n1 and mostly raided with the exception of /boot/efi which is copied to an alternate /boot/efi-backup.

The nvme ssds are Samsung 960 evos which unfortunately are known to cause hangs. The bootparam nvme_core.default_ps_max_latency_us=0 seems to mitigate this and there is evidence of a fix in future kernels.

The laptop came with windows home on a sata disk /dev/sda which can still boot by way of f12 /boot menu.
