[Bug 1244646] [NEW] Unable to switch from xorg to terminal mode

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When using two external displays, upon pressing ctrl-alt-f1 the
following appears in /var/log/syslog

Oct 25 14:38:38 nb-10512 kernel: [ 1584.547279] detected fb_set_par
error, error code: -22

The image freezes until I return to X by pressing ctrl-alt-f7.

When using only one external display, the terminal appears as expected
when pressing ctrl-alt-f1.
