The various systemd units involved assume that you have KDM set up like Fedora does, with the |
| 69 |
first graphical terminal (:0) on tty1, so kdm.service actually *conflicts* with getty@××××.service. |
| 70 |
|
| 71 |
If you actually want to set up kdm to act in this manner, edit the file |
| 72 |
/usr/share/config/kdm/kdmrc and change the following options in the [General] section: |
| 73 |
ServerVTs=1,-7 |
| 74 |
ConsoleTTYs=tty2,tty3,tty4,tty5,tty6 |
| 75 |
|
| 76 |
If you don't want kdm.service to conflict with getty@××××.service, copy the file |
| 77 |
/usr/lib/systemd/system/kdm.service to /etc/systemd/system/kdm.service, and remove the line: |
| 78 |
Conflicts=getty@××××.service |
| 79 |
