I checked everything that (pleasantly short) article indicates. Most of |
| 11 |
it was already in place, except the input group permission. I took care |
| 12 |
of that by making Xorg setgid to the input group. But no luck: it |
| 13 |
still fails exactly the same way: |

Looking at kernel sources, it seems obvious this means the test at |
| 20 |
drivers/tty/vt/vt_ioctl.c around line 360 in vt_ioctl() fails. Any idea |
| 21 |
why it would fail for me and not others? In particular why is it that |
| 22 |
the X process has no controlling tty by this point - that's the check I |
| 23 |
would expect to succeed? |
