Hi Guixers, (define myself (guix-noob-user (not (programmer)))) Trying to change console font with the following in "services" section of my system configuration file : ---- … (services (append (list … (service console-font-service-type `(("tty3" . ,(file-append font-terminus "/share/consolefonts/ter-128n")))) ) %desktop-services)) … ---- which results in the following error when reconfiguring the system : ---- $ sudo guix system --dry-run reconfigure /etc/config.scm guix system: error: service 'console-font-tty3' provided more than once ---- I probably missunderstand something and/or ill-format the configuration…?… Help appreciated. Below is the related [(guix) Base services] Texinfo section. ---- --scheme Variable: console-font-service-type Install the given fonts on the specified ttys (fonts are per virtual console on the kernel Linux). The value of this service is a list of tty/font pairs. The font can be the name of a font provided by the ‘kbd’ package or any valid argument to ‘setfont’, as in this example: `(("tty1" . "LatGrkCyr-8x16") ("tty2" . ,(file-append font-tamzen "/share/kbd/consolefonts/TamzenForPowerline10x20.psf")) ("tty3" . ,(file-append font-terminus "/share/consolefonts/ter-132n"))) ; for HDPI ----
