Description Flags
patch to use VT_ETSTATE and tty0 none

Description Peter Jones 2007-10-30 18:45:58 EDT
Description of problem:  ConsoleKit tries to find a valid fd it can issue
VT_WAITACTIVE against by iterating across a file list and issuing 
ioctl(fd, KDGKBTYPE, &arg), then checking the return value.  Not all console
devices support this ioctl, so in some cases it never finds a valid file
descriptor to use, and from then on never marks any session active.

We probably ought to be using something like VT_GETSTATE instead of a keyboard
ioctl, but that's not sufficient to fix it.  One fix that seems to work, though
I'm not completely sure if it's the best answer, is to add /dev/tty0 to the list
of files to try before /dev/console.

I've attached a patch that seems to resolve the issue for me.

Comment 2 Peter Jones 2007-10-31 10:34:38 EDT
(Comment #1 should say VT_GETSTATE, of course)
Comment 3 Lubomir Kundrak 2007-12-03 08:51:06 EST
Raising priority to high, keeping track of active sessions is fairly important.
Furthermore the fix is attached to this problem.

I found this issue while determining why was my desktop user unable to hibernate
a machine. This fix fixes the problem for me. The workaround was to run the
consolekit daemon with --no-daemon option which caused it to find the active tty

Sorry this bug got lost for me. Jon, what do you think? Thanks.
Comment 5 jmccann 2007-12-03 14:14:49 EST
Hi, sorry for the lag.  I think this looks reasonable.  I'll test and commit
this as soon as I get my development machine back up (hopefully in the next few
days).  Thanks.
Comment 6 jmccann 2007-12-08 23:04:43 EST
In git now.  Thanks for the patch Peter.
Comment 7 Lubomir Kundrak 2008-01-19 09:12:43 EST
I'm wondering if there's a chance that ConsoleKit update will occur for Fedora
8. In case yes, this fix is a good candidate to be included :)
