This article is specifically about the System76 Oryx Pro versions 6-8, all of which share the same chassis and a very similar architecture. The latest available model is oryp8.

Booting

The System76 Oryx Pro comes with two NVMe M.2 slots. Older models (pre-oryp6) have space for a 2.5" SSD/HDD. Booting from NVMe requires the use of EFI, while booting over SATA/AHCI does not. If you are not sure what to use, EFI is a sensible and safe default for all configurations of this machine.

Accessibility

BIOS

The BIOS menu is extremely minimalist, with essentially no settings outside of boot order. All entries can be accessed from the keyboard, and should be easy to OCR.

There is no official documentation around which buttons to press to enter the BIOS. The splash screen says that Esc opens the overall BIOS menu, and Space starts the Pop!_OS recovery partition.

Within the BIOS menu, you can use the arrow keys (Up/Down) to move the cursor, the Enter/Return key to activate or save things, PageUp/PageDown to relocate things, and Esc to cancel an operation or to go back to a previous menu. All lists are vertical, and progress from top-to-bottom.

  1. The first option in the BIOS menu is "Boot Default", and it is where your cursor starts out. Activate this to continue the boot as if you had not pressed Esc at all.
  2. The second option is "One Time Boot". This provides a menu of all boots known to the BIOS, in the order the BIOS knows to boot them. The cursor starts at the top of this menu. Activate one to boot to it.
  3. The third option is "Change Boot Order". This one is a bit odd, as you have to press Enter/Return twice to use it, after which you will be in an ordered list of possible boots, which can be mutated using the controls describe above. Note that Esc must be pressed twice to return to the main menu. There is an open ticket to simplify this flow here.
  4. The fourth (and final) option is "Firmware Configuration Information". This page simply lists information about the firmware.

LEDs

There is no diagnostic LED on the motherboard. The official technical documentation does not discuss whether the motherboard beeps when there is an issue, nor does it say what such beeps could mean.

There are three status LEDs on the front-left of the bottom half of the laptop. The left LED is for power, the center LED is for the battery, and the right LED is for IO. More information can be found in the official technical documentation.

Installation

System76 develops a special distribution (Pop!_OS) for their computers, and it comes with many tweaks and tools to ensure a seamless end-user experience. Arch does not have these out of the box; and unfortunately, sometimes their computers do not work right without them. Thankfully, it is possible to get the same first-class hardware support in Arch Linux that you have in Pop!_OS -- it just takes a little elbow grease.
(The rest of this article will assume you have followed the steps given in this section.)

Recovery partition

If you are replacing Pop!_OS on the NVMe that came with your laptop, it is recommended to leave the recovery partition intact. The BIOS is hard-coded to attempt to boot this on Space, and this recovery partition can be a handy way to get out of a tight spot if something should happen that renders your Arch install unbootable.

System76 automatically updates this recovery partition from within Pop!_OS; at present, it is not known how to update it from within Arch Linux.

It may be possible to replace the contents of this recovery partition with any LiveCD you want, but as of now it is not known if anyone has tried.

Kernel

While the oryp7 is known to at least boot with Linux 5.13, there will be missing functionality until 5.15 and higher, because System76 pushed several patches to upstream that were not merged until then. Accordingly, it is not recommended to use a kernel older than 5.15.

Packages

All necessary packages can be found in the AUR. It is recommended to install everything in the list below.
(There are also "-git" versions of many of these packages, if you wish to be bleeding edge.)

Modules
Daemons
Note:
  • For whatever reason, these packages are prone to breaking. It would be nice if someone would be willing to provide a System76 repository with prebuilt binaries.
  • Several of these are bundled in the Pop!_OS kernel. Building that kernel for Arch would get all the functionality of those packages in a single step. As well: there is some functionality in the Pop!_OS kernel that you can't get elsewhere; meaning that, without it, our Arch installs are deficient.

Activation

Once you have installed the above, you will need to tell your computer to use them.

Services

Enable the following services: (source)

  • system76
  • system76-firmware-daemon
  • system76-power
Modules

To make sure all drivers are being loaded correctly, run system76-driver-cli; this will automatically add necessary rules to /etc/modprobe.d, and execute mkinitcpio.

Note: As of 2021-04-06, this creates a malformed s76-i915-mkinitcpio.conf file, and a redundant (if you have system76-power.conf) system76-driver_i2c-nvidia-gpu.conf file. As such, this step may be skippable, for the time-being. Nevertheless, there is a known solution for the malformation: simply append 1 to options i915 in s76-i915-mkinitcpio.conf. (source)

Firmware

Install the following:

To check your current BIOS version and whether there is a new version available, run firmware-manager as root. Keep in-mind that this is a GTK application, so you need to be running X or Wayland for it to run. (It has no CLI -- it does not even respond to --help.)

To update your system to the latest firmware on the next boot, run system76-firmware-cli schedule.

EC

"EC" refers to the "embedded controller", and is where the bulk of user-relevant settings exist in the BIOS.

System76 may not provide firmware updates for your model forever; and those they do provide often do not come out in a timely manner. Thankfully, you can flash the latest version of the EC from GitHub (with all its numerous fixes) yourself, by first cloning the repository and then running the following command: make BOARD=system76/$MODEL flash_internal -- just make sure to replace $MODEL with your actual model (eg "oryp8"). System76 performs QA on all PRs before they are merged into master, meaning that master can generally be considered stable.

Note:
  • Be sure to save your work -- this command will intentionally cut power to your laptop after it finishes. There is an open GitHub issue requesting a fix for this.
  • Flashing an unreleased version of the EC may result in a situation where you become unable to accept official firmware updates. This is easy-enough to fix: you need to flash an .iso to a thumbdrive, remove all internal drives from the system, insert that thumbdrive, and power on. The .iso you need can be acquired from System76 support.

BIOS Settings

Fan curve

The Oryx Pro's fan curve is hard-coded, meaning you have to configure, compile, and flash your own custom version of the EC in order to change your fan curve. (There is an open issue to add runtime-configurable fan curves here.).

Note: Some fan speeds are likely to cause rattling; see #Noise for more information on this.

The default fan curve for the all System76 computers is designed to minimize noise (source). Unfortunately, in the Oryx Pro's case, this goal is taken to an extreme: by default, the fans will only reach 100% at 90°C; and your CPU starts to throttle well before that point. By setting a custom fan curve that reaches 100% at Tjunction (typically a few degrees above 70°C), you can easily avoid such unnecessary throttling.

There is a PR available that fixes these issues for the oryp7.

Voltages

There is no user-configurable option to change voltages at the BIOS-level. However, some have managed to disable the Plundervolt mitigations, in doing so re-acquiring the ability to undervolt their Oryx Pros from userland. There is an issue on GitHub requesting a toggle in the BIOS for this mitigation.

Graphics

This system comes complete with an integrated (Intel) and discrete (NVIDIA) graphics card. The external ports (DP over Mini-DP, DP over USB-C, HDMI) are tied to the discrete Nvidia card.

Graphics options:

  • System76: If you want to use the hybrid graphics mode developed by System76, follow the instructions in #Installation and #OEM switchable graphics. This seems to use PRIME behind the scenes.
  • Bumblebee: Some users have reported getting success with Bumblebee. Your mileage may vary if you are using a more complete DE like GNOME; this has only been tested with i3-wm.
  • NVIDIA: When in doubt, NVIDIA's official drivers should always work.

OEM switchable graphics

To enable System76's switchable graphics, run system76-power graphics hybrid once; and then put prime-run before every application you want to start with your dGPU. Note that this will only work for applications that use GLVND. (source)

Note:
  • Officially, you need to cold-reboot your device every time you change your switchable graphics setting.
  • The devs have confirmed that while you can technically switch between hybrid and compute without restarting your whole computer, you must still restart X in order for the change to take effect.
  • Switching from hybrid to integrated will display as compute until you restart. While confusing at first blush, this is intended behavior, and technically correct. (This note is here because at least one person was confused by this.)

To verify whether switchable graphics is working, run glxinfo and prime-run glxinfo. These commands should succeed and have different vendors. If the latter command fails, go to #prime-run not working. (Note that you can limit the output to just the relevant information by appending | grep -i vendor to the aforementioned commands.)

Audio

oryp6

The Oryx Pro 6 has audio that works perfectly fine out-of-the-box.

oryp7 / oryp8

Audio should work out-of-the-box with a USB headset; however, you may find that the onboard speakers are wholly unresponsive. Pop!_OS always has its kernel patched to work with Realtek PCI's quirks, thus avoiding this kind of issue; but Arch, which uses upstream Linux kernels, often has to wait quite some time to see these patches trickle down.

The following parameters can be added to /etc/modprobe.d/clevo-p950.conf to get your speakers working if your kernel does not yet support them: options snd-hda-intel model=clevo-p950. While the oryps 7 & 8 are not Clevo P950s exactly, this workaround provides the same ALC1220_FIXUP_CLEVO_PB51ED_PINS quirk that the oryps need. (source) While this workaround does enable headphone and speaker audio, it may interfere with headset mics -- your mileage may vary. (source)

Ethernet

The oryp7 has a Realtek ethernet chip whose in-tree Linux driver is (as of Linux v5.15) guaranteed to fail link autonegotiation. You can work around this issue by manually setting your onboard ethernet's link negotiation to 'ignore' or '100mbps' (How you do so depends on your computer's network manager.); however, both options mean that your Internet speed will be capped at 100mbps. In order to get your ethernet port to work at speeds above that, you will need to install Realtek's out-of-tree driver, with r8168, r8168-lts, or r8168-dkmsAUR (Although r8168 is out-of-tree, it is still open-source and GPL-licensed.). Once installed, you need to blacklist the default r8169 driver: echo "blacklist r8169" > /etc/modprobe.d/r8169_blacklist.conf.

  2. The Fn in this combo is ignored unless you have compiled and flashed an unreleased version of the EC.
  3. Pause/Break and PrintScreen/SysRq have the same scancodes on PS/2-style keyboards, so they require additional modifiers for the OS to understand them. (source)
  4. This key depends on your layout, and may be different if you are not using QWERTY.

Keyboard lighting

You can control the brightness and color of your keyboard's LEDs. To do so, install sys76-kbAUR and then run sys76-kb set -b $B -c $C, with $B being how bright you want the keyboard (on a scale of 0-255) and $C being a 6-digit color hex (eg, "ffffff"). Since the keyboard's LEDs are controlled from the commandline, it is possible to script patterns and light shows.

Note that these settings are not maintained across boots; so you will need to reapply them on startup.

Note: Do not set your brightness lower than 100%, or the colors your keyboard displays will be random and unpredictable. (This is a known issue with the firmware.)

Hardware

The Oryx Pro 7 (and likely also its cousin models, 6 and 8), while a capable machine, has a number of noticeable shortcomings in hardware that, thankfully, can be largely resolved by a little elbowgrease.

Model correspondences

The Oryx Pro, like most (all?) System76 laptops to-date, are derived from Sager/Clevo models. The below table shows which models correspond to each other. This can be useful when shopping for parts online.

Heatsinks

Thermal paste/pads

As confirmed to an attendee of Southeast Linuxfest 2022 by a System76 employee, System76 (like most OEMs) uses the cheapest, most-generic thermal paste it can find, in order to reduce costs at scale. Repasting your CPU/GPU can result in noticeable improvements to the speed at which they decrease in temperature after a spike, but it will not prevent such spikes from happening; see the "Main heatsink" subsection here for information about why that is.

Upgrading the stock thermal pads can also improve heat transfer, but System76 has confirmed (via support ticket) that it does not have any documentation on the proper thicknesses to use for these pads, meaning that replacing them bears risk that replacing the paste does not.

Main heatsink

The heatsink that cools the CPU and GPU does not have enough thermal capacity to cool them (the CPU especially). What this means, in practice, is that you will see WILD temperature swings at even mild usage: it is common to see going from 1% usage to 10% usage result in a jump from 50°C to 90°C in less than a second. The only solution to this, is to add more thermal capacity to the heatsink. The easiest and cheapest way to do this, is to lay thermal pads on-top of the main heatsink, until those pads start to squish into the aluminium chassis at the bottom. This will substantially ameliorate such jumps in temperature, and the corresponding fan spin-up that follows them. (source) An added benefit of tying your main heatsink to your bottom chassis, is that the bottom chassis is fan-cooled, just like your main heatsink -- which means that not only are you adding extra thermal capacity, you're also increasing the amount of active cooling you have.

PCH

The PCH comes without a heatsink, and will idle around 85°C. This is obviously not good for longevity. Adding a small heatsink to it can make a nice difference; but you can get an even bigger one by first building up the area around the PCH with thermal tape until you are level with the die, and then affixing a wider heatsink to the whole area. Yet more gains can be had by removing the insulating plastic directly above this heatsink, and replacing it with a thermal pad; this will create thermal contact between your DIY PCH heatsink and the laptop's aluminium chassis. Combining all of these tricks gets a PCH that idles around 40°C -- that's an unheard-of 45°C drop.

NIC

The NIC comes without a heatsink, and can idle around the 65°C range. Adding a heatsink and ensuring thermal contact with the aluminium chassis can lower this by 15°C.

Noise

Fans

Many, though not all, users have reported hearing a "clicky" noise in the fans when they spin up or down. System76 has introduced a 25% floor for fan speeds, in an effort to reduce this; but it still happens for some users. Your best bet, if you are affected by this, is to file a ticket with System76 support, asking for new fans. If you are under warranty, these should be provided to you if you can procure an audio recording of the clicking; if you are not, then you will have to pay for the fans.

In addition to or as an alternative to replacing the fans, you can also try changing the speed floor. Some people will be able to use values as low as 20%; others may need to go up to 30% or higher. See #Firmware for more information around how to change your fan curves.

Coil whine

Some users report very noticeable coil whine. There's not much that can be done about this, but you can try coating your motherboard and other components in insulating varnish, taking great care to avoid coating surfaces you might want to attach thermally-conductive material to later-on. This coating may not completely resolve the issue, but should help to mute it somewhat.

Keyboard

The spacebar may never actuate if pressed on its sides. This is because its stabilizers are quite flimsy. If you want to use the whole length of your spacebar, you will need to replace the stock stabilizers with some custom ones made of spring-steel wire.

Troubleshooting

Weird hardware issues

Shut down − do not simply restart when encountering weird issues (e.g. where system76-power throws a strange error, and rebooting does not help). As explained by a System76 engineer at Southeast Linuxfest 2022, shutting down hard-resets certain components that stay on during reboots.

Bad thermals

For software-level fixes, see #BIOS Settings.
For hardware-level fixes, see #Heatsinks.

fancontrol not working

system76-acpi-dkmsAUR does not currently support runtime configuration of fan speeds, so pwmconfig and fancontrol will not work. There is an open feature request for this, though.

In the meantime, you can hard-code a custom fan curve per the instructions in #BIOS Settings.

prime-run not working

Try creating /etc/X11/xorg.conf.d/90-intel-nvidia.conf and adding the following to it: (source)

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "iGPU"
EndSection

Section "Device"
    Identifier "iGPU"
    Driver "modesetting"
    BusID "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier "iGPU"
    Device "iGPU"
EndSection

Section "Device"
    Identifier "dGPU"
    Driver "nvidia"
    BusID "PCI:1:0:0"
EndSection

Change the BusID fields above to match the first field in the output of this command: lspci | grep −E "VGA | 3D" (you can omit leading zeroes). You will need to restart your X server for this to take effect.

Xorg fails to start with "No devices detected"

If you find (normally after an update & restart) that launching X (via startx or otherwise) does not work, you may confirm that the nvidia device is installed and working by doing the following:

Confirm the error in ~/.local/share/xorg/Xorg.0.log. The nvidia kernel module should successfully load. You may also confirm the error with dmesg or journalctl.

Check whether both integrated and discrete graphics cards are available:

# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
01:00.0 VGA compatible controller: NVIDIA Corporation TU106M [GeForce RTX 2070 Mobile] (rev a1)

If you do not see the second entry (or some similar NVIDIA card), make sure the card has been turned on by system76-powerAUR (use --help to explore options):

# system76-power graphics 

Check whether the discrete NVIDIA graphics card is powered on using system76-powerAUR:

# system76-power graphics power

To power the discrete NVIDIA graphics card on, supply "on" as an argument (i.e. system76-power graphics power on). After doing so and querying again, you should see:

# system76-power graphics power
on (discrete)

Once the card is powered on, it should show up in the output of lspci, and be detectable by Xorg, given that the appropriate NVIDIA driver is installed.

system76-firmware: EFI mount point not found

If using the new (replacement) EFI mount point /efi, ensure you have the mount present in etc/fstab. You may find the appropriate device to mount by using a combination of lsblk and fdisk -l.

# fdisk -l # List disks (one device will be designated as "EFI System")
# lsblk    # List devices and mount points, you should see the EFI system device, and confirm whether it is mounted/unmounted
# mount device /efi
#
# genfstab -U / # (optional) print fstab configuration for inclusion/merging into /etc/fstab

After doing the above, it might be a good idea to schedule a firmware update:

# system76-firmware-cli schedule

With grub

After scheduling a firmware update, ensure that GRUB is set to use the EFI partition like so:

# grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=grub
# cp /boot/grub/grub.cfg /boot/grub/grub.cfg.bak
# grub-mkconfig -o /boot/grub/grub.cfg

Restart to trigger the firmware update.

X does not start

If you have anything plugged-into the HDMI port on the back, this is why. Unplug your HDMI cord, boot the computer, and plug it back in after X starts. This issue only happens when the Nvidia card is used for display, either in dedicated or hybrid mode; so if you do not want Nvidia to do your graphics anyway, switching to compute or integrated will fix this problem. If you actually do want to use your Nvidia card, though, there is currently no known fix; but watching Linus swear at Nvidia may prove therapeutic. Worth noting, though: Pop!_OS handles this just fine, so there may be something missing in Arch that is not missing in Pop!_OS.
