Hello!
tl;dr Something is causing linux 5.4.20 not to load kernel modules at boot. Perhaps the culprit is the shepherd 0.7.0. So I recently reconfigured guix on my ThinkPad T400. #+BEGIN_SRC sh $ guix describe Generation 32 Feb 18 2020 16:53:46 (current) jmacs 1a401c8 repository URL: https://notabug.org/jbranso/guix-packages.git branch: master commit: 1a401c81ed0617e2ca2fa37ec8caa9ca96032b7a guix 97c6670 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 97c6670ef79bbf5e82dece2e837ed73b6462da01 #+END_SRC After I rebooted sway refused to start. The sway error message said #+BEGIN_SRC sh $ sway [backend/backend.c:339] Failed to open any DRM device. [sway/server.c] Unable to create backend. #+END_SRC So sway is not starting. I believe this is because my i915 intel driver is not loaded. I know this is the case, because the text on my virtual console is LARGE. $ sudo modprobe i915 loads the required driver. And I can now log into sway. However, my ethernet driver is not loaded. #+BEGIN_SRC sh $ lsmod | grep e1000e #+END_SRC #+BEGIN_SRC sh $ sudo modprobe e1000e #+END_SRC Then I ran ifconfig, and indeed I now have an ethernet device. #+BEGIN_SRC sh :results output :exports both $ ifconfig enp0s25 Link encap:Ethernet HWaddr 00:1C:25:9A:37:BA inet addr:172.16.113.199 Bcast:172.16.115.255 Mask:255.255.252.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:505 errors:0 dropped:0 overruns:0 frame:0 TX packets:570 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:143838 TX bytes:60886 Interrupt:20 Memory:fc100000-fc120000 lo Link encap:Local Loopback inet addr:127.0.0.1 Bcast:0.0.0.0 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 TX bytes:0 #+END_SRC And I now have an internet connection. #+BEGIN_SRC sh :results output :exports both joshua@dobby ~/prog/org$ ping -c 3 gnu.org PING gnu.org (209.51.188.148): 56 data bytes 64 bytes from 209.51.188.148: icmp_seq=0 ttl=56 time=35.610 ms 64 bytes from 209.51.188.148: icmp_seq=1 ttl=56 time=35.635 ms 64 bytes from 209.51.188.148: icmp_seq=2 ttl=56 time=35.501 ms --- gnu.org ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 35.501/35.582/35.635/0.058 ms #+END_SRC But I do not have a working touchpad. I guess my touchpad driver is not loaded. I'm not certain what driver my touchpad uses, so for now I am doing with out. I then went and asked for some tips on irc. HappyEnt claimed the problem for him was commit 205c1e0. janneke was also having issues with kernel modules not being automatically booted. He said that this commit worked for him: ef2b1d2c8b60776bf66573b0c810474e9e1a4abd. He then said that commit d39885a8a9e0e03c2bf6277d475d384168bba642 also worked, which implied the problem was not the linux version 5.4.20, but possibly the shepherd. I tried reconfiguring with commit d39885a8a9e0e03c2bf6277d475d384168bba642, to see if that solved my issue. #+BEGIN_SRC sh :results output :exports both guix time-machine --commit=d39885a8a9e0e03c2bf6277d475d384168bba642 -- system reconfigure #+END_SRC #+BEGIN_SRC sh $ uname -r 5.4.20-gnu #+END_SRC janneke's commit did solve my issue. After rebooting, sway starts, I have internet, and my touchpad and sound work. Man I love guix system. It really does work smoothly, even when you have problems. So thanks for making a great GNU/Linux distro! Thanks Joshua
