Ctrl-Alt-F1,F2,F3 ... can not start a console.

Ctrl-Alt-F1,F2,F3 ... can not start a console.

[Feng Shu]

Yestaday, I reinstall my guixsd, and install xfce4 as my desktop.
A problem faced is that: When I press Ctrl-Alt-F1, F2, F3 ...
I can not start a tty, instead of start a slim login picture?

Any suggestion? thanks!

Just the other day, I discovered that in GNOME, I could not switch to a
virtual terminal by pressing Ctrl-Alt-F2.  Instead, the screen would
simply appear to freeze until I pressed Ctrl-Alt-F7 again.

In my case, this problem only occurs when I've connected an external
monitor to my laptop.  When I unplug the external monitor, I am able to
successfully switch to a virtual terminal by pressing Ctrl-Alt-F2.  If
you are using an external monitor, then perhaps you should try
unplugging it first?

Hi,

Can you reproduce the problem in a VM created by ‘guix system vm’?
(Note that in QEMU you need to do ctrl-1 to go to the QEMU console, then
“sendkey ctrl-alt-f1”, and then ctrl-2 to switch back to the VM screen.)

If not, could it be that the problem has to do with the graphics driver
being used?

I run command: dmesg, and find error:

is it possible the reason?

qemu vm works well, may be it is graphics driver problem as you said, I
will wait to update driver, thanks for the help!

When I revert "gnu: xf86-video-ati: Update to 7.10.0." , it works well.

Uff.  I suspect it's related to this snippet from the ChangeLog[0]:

* The driver now takes measures to prevent other DRM master processes
  (potentially from other local users) from accessing buffers created by
  this driver while switched away to a different VT. Other DRM master
  processes should only be able to access a single buffer anymore, which
  contains only all-black pixels.

Are you willing to report this bug upstream?  See here for information:

https://freedesktop.org/wiki/Software/xorg/

We should probably revert this on 'master' meanwhile.  Unfortunately I
don't have ATI hardware to test with, so it would be good if someone
else could try to reproduce this problem.
