Hello Kodcu. According to h-node.org, the ThinkPad T440p uses Intel graphics and not Nvidia/nouveau. Graphics are claimed to work with the libre kernel.
I presume you can switch to a TTY by pressing Ctrl+Alt+F2 at least after booting with nomodeset. If graphics actually do not work and you do want a graphical system, it might be possible to use an older kernel. Add a line inside /etc/config.scm to the operating-system: (use-package-modules linux) (operating-system (kernel linux-libre-5.4) … or some other old version. Otherwise, uvesafb is an option but not a good one. It would be much better without uvesafb. The installer’s config file uses uvesafb, the installed system does not by default (see <https://lists.gnu.org/archive/html/help-guix/2020-11/msg00172.html> which can also be found using the yhetil.org search engine). Regards, Florian
