Hi,
I'm having a pretty dramatic experience changing console, f.ex.
Ctrl+Alt+F4. My system becomes completely unresponsive. Even
Alt+SysRq+reisub is unable to persuade my system to perform a gentlemans
reboot. To recover I must do a hard reboot.
Bringing this up in #guix suggests it's not a common issue.
My setup is:
Libreboot X200
Docking station
External monitor connected to the docking station with DisplayPort.
XFCE
GuixSD (from git, last commit in my repo
c11933c920dd7b7cdf68e13e6b3718602129210a)
Using DisplayPort I sometimes get the attached output. Other times I get
a white underscore in the top left corner on a black background.
Now, if I change video output to Laptop monitor and unplug the
DisplayPort cable I can change consoles. (Only setting video output to
Laptop is not enough, the cable must go.)
If I use VGA instead, changing consoles seems to work fine. However
running command "dmesg" tells of a Call Trace that looks much like the
Call Trace I sometimes see when my system becomes unresponsive
(attached), though a bit shorter.
---This is dmesg after changing consoles with VGA:---

I have no idea if this is really a Guix issue or not, maybe it's
Linux-libre?
Let me know if I can be of any assistance.

I definitely don’t experience that on my laptop (not an X200). Perhaps
the KMS module and Xorg driver is at fault? Which ones are in use?
(My laptop has an Intel graphics card, so i915.ko, though for some
reason Xorg uses xf86-video-intel instead of “modesetting”.)

Did you try using an external monitor connected with DisplayPort?
KMS Module in use (from /var/log/Xorg.0.log):
[ 18.862] (II) intel(0): Using Kernel Mode Setting driver: i915,
version 1.6.0 20160711
As for Xorg driver in use, I'm not sure where or how to find this out.
Grepping /var/log/Xorg.0.log for LoadModule in case that's helpful. If
not, let me know how I can find it.

No, I only tried VGA and HDMI outputs, which work fine.

OK.
Could you check maybe whether other X200 users have that problem? It
doesn’t seem to be GuixSD-specific.
Did you have success with another distro on this laptop? If so, it
would be good to see the difference in terms of drivers and versions.
