Of course I meant /sys/power/state, not /sys/state/power... Also: Using <sudo ...>, the screen blackout (and subsequent logging of "Failed to open /sys/power/state: Permission denied" in tty1 no longer show up after using gnome-tweak-tool to set "Don't suspend on lid close" to "ON" in "Power > When Laptop Lid is Closed".
NB, this does not solve the 30-second suspend thing; I still need to do a chmod 444 on every boot to make sure I can use my laptop for more than 30 seconds at a time. 2017-07-28 1:41 GMT+02:00 Jelle Licht <[email protected]>: > Hello help-guix, > > I recently acquired a Lenovo T400 laptop with libreboot installed from > minifree.org. > Of course, I wanted to get GuixSD on there as quickly as possible and got > to work. > > I am using GuixSD by installing with the --no-bootload flag, and copying > the generated grub.cfg to /boot/grub/libreboot_grub.cfg (which allows the > grub-in-libreboot to find my grub config and subsquently boot into GuixSD). > > I started out with the bare-bones OS config, which worked perfectly. > Then I started playing around with a very straight-forward gnome config > (see attached config.scm). > > About every 30 seconds (could be 29~32), my laptop goes into suspend mode! > This means that the screen turns black, the backlight is turned off and as > far as I can tell, the fan is also not making any noise.
