CachyOS kernel rolls 7.3-rc4 and enables oomd
By RepoJournal · composed from the cited sources · human-reviewed weekly · methodology
Both kernel tracks shipped this week, and cachyos-settings turned systemd-oomd back on by default after kernel OOM regressions.
CachyOS Linux 7.3-rc4-2 CachyOS/linux
The rc4 re-spin adds the 7.3/xswapv5 branch on top of 7.3-rc4-1, bringing swap-side table publication fixes to the virtual swap work. RC users should move to this point release before further testing.
Return systemd-oomd configuration (#269) CachyOS/CachyOS-Settings
The revert restores the oomd configs that were dropped when they conflicted with le9, this time with killing keyed to swap usage rather than memory pressure alone. If you use le9, your machine now runs both.
cachyos-settings: Enable oomd by default CachyOS/CachyOS-PKGBUILDS
The settings package flips oomd on across the board, not just for users who opted in. Fresh installs and existing systems that pull the update will have the daemon configured after their next upgrade.
modprobe/nvidia: Remove NVreg_DynamicPowerManagement setting (#271) CachyOS/CachyOS-Settings
The NVreg_DynamicPowerManagement setting is gone from the modprobe config, so the driver default applies instead of a forced value. Systems that relied on the old setting for runtime power saving should verify their dGPU still suspends.
profiles/nvidia: Setup DynamicPowerManagement value only for Turing (#280) CachyOS/chwd
chwd now writes the DynamicPowerManagement value only on Turing and newer, matching the narrowing of dynamic power management support to those GPUs. Pascal and older cards no longer get a setting they cannot use.
profiles/nvidia: Do not use lspci to check on NVIDIA dGPU (#282) CachyOS/chwd
The NVIDIA profile stops calling lspci to detect a dGPU. Chwd's own commit message says lspci walks every PCI device, which "can accidentally cause NVIDIA dGPU to exit from sleep state (adds delay when starting at ~1s)", so startup detection is faster and no longer wakes the card.
Sync plymouth keymap-render.png with installed plymouth CachyOS/CachyOS-PKGBUILDS
Both cachyos-plymouth-theme and cachyos-plymouth-bootanimation ship a static keymap-render.png that is sliced by pixel offsets baked into the installed plymouth package. The image is now synced to that package, fixing the LUKS unlock screen drifting out of alignment after upstream plymouth releases.
Make plymouth optional (#273) CachyOS/cachyos-calamares
The installer moves plymouth out of pacstrap and into netinstall, and the config step verifies the chosen theme is actually installed. Calamares installs no longer drag in plymouth for everyone. Alongside: mutter was forked for tearing support, the NVIDIA RTD3 workaround was dropped, devtools gained a networkd log level patch, and the AUR-derived set picked up clipman 1.7.0, lib32-opencl-icd-lo...
