Re: Does Linux 4.16.1 blast out battery time? (9h+ -> 3h+)

Upon reboot, my laptop's battery time had changed from 9h+ to 3h+! Quite a dramatic regression indeed... General usage (startup time, etc.) seems to be somewhat slower as well. As a test, I ran another system reconfigure, changing only the kernel version: now on 4.14.33, I'm back to 9h+. Does anyone know something about this or should I reach out for the Linux mailing list? Note that before installing GuixSD, I was running Void Linux with kernel ~4.14.5 (off the top of my head) and battery time was 12h+. This might be due to the discrete Nvidia card which was completely shut off by default, while it's now running with nouveau on GuixSD but I don't know how to turn it off. Insights? I'm not aware of any regression but I'd recommend to install powertop and check, which processes are preventing CPU from switching to power saving modes. Sometimes it provides interesting results - I usually can spend like 40% more time on battery by closing Icecat and Pavucontrol. It also can help you with tuning common power management controls.

Re: Dual-booting solution with only one actual Grub installation

You can let Grub2 offer an item that will load another grub.cfg. In my case, that's a Grub installed from Ubuntu, with a menu that will be updated in sync with kernel installation/removal, plus one "Guix SD" item that will lead to the known Guix SD menu, also always up-to-date, without an actual second Grub installation. No manual updating, no chain-loading of one or the other from an independent third Grub. Guix SD: /etc/config.scm, in operating-system: (bootloader (bootloader-configuration (bootloader (bootloader (inherit grub-bootloader) (installer #~(const #t)) Very nice indeed! Thanks for sharing.

Re: which of the two ArchLinux PKGBUILDs is better ? -- guix on Arch success

Please enlarge your swap file and resize /tmp to like 20 GB, else you will repeatedly break during Or you can set TMPDIR variable for guix-daemon.
