User:Gig/System76 Oryx Pro
The Oryx Pro is a customizable laptop sold by System76. Among other features, it has dedicated graphics with an RTX 3070 (as of early 2022), a 1080p 144Hz display (15" or 17"), and System76's fork of coreboot.
- The laptop does not have support for PXE/network booting. Therefore, some external bootable media (e.g. flash drive) is likely necessary for installing Gentoo.
X Server Freezing
When the dedicated GPU is under a very light load (as is usually the case on first startup or after closing graphics-intensive programs), the X server can lock up entirely. When this happens, the laptop will no longer respond to user input, but it is still possible to manage it remotely. A power savings issue is suspected to be the cause of this freeze.
A potential workaround exists in system76-power. At time of writing, there is no ebuild available for this software, so it has to be set up manually.
Clone the repo:
git clone https://github.com/pop-os/system76-power && cd system76-power
Build and install:
"make install" will install some systemd-specific service files. The command will print the paths to said files, should you want to investigate or remove them.
Before starting X, run the daemon:
Enable NVIDIA-exclusive rendering and, optionally, switch to the "Performance" power profile:
system76-power graphics nvidia
system76-power profile performance
