Are you sure this is fixed? I'm seeing this exact bug in Trusty. Logging out of a TTY doesn't lower the number of users in uptime, w, etc.
Now, Vivid switched to systemd, so if the bug is really in upstart, it may not be worth wasting time here. But, Trusty is an LTS... so, I don't know. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/183729 Title: compat: utmp not cleared on tty logout Status in upstart : Fix Released Status in kdebase-workspace package in Ubuntu: Invalid Status in upstart package in Ubuntu: Fix Released Status in upstart package in Fedora: In Progress Bug description: Log into tty1, then tty2 and then log out of both. Now run a w command and you should see something similar to the following; mac@tootoo:~/source/procps-3.2.7/proc$ w 10:39:09 up 33 days, 23:11, 4 users, load average: 1.31, 0.62, 0.39 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT mac tty7 :0 11Jan08 4:34m 7:24m 36.02s x-session-manager mac pts/1 :0.0 08:54 0.00s 0.19s 0.00s w It shows that 4 users are logged in. Obviously this is wrong. I wrote a small C utility to hack out what w and uptime get as information from utmp. #include <string.h> #include <stdlib.h> #include <pwd.h> #include <unistd.h> #include <utmp.h> #include <stdio.h> int main(int argc, char *argv[]) { struct utmp *utmpstruct; struct utmp entry; //system("echo before adding entry:;who"); setutent(); //pututline(&entry); while ((utmpstruct = getutent())){ if ((utmpstruct->ut_type == USER_PROCESS) && (utmpstruct->ut_name[0] != '\0')) printf(utmpstruct->ut_line); printf("\t"); printf("%d",utmpstruct->ut_pid); printf("\n"); } endutent(); return 0; } You'll get an output like this mac@tootoo:~$ ./a.out 0 50 4305 4306 tty2 14989 4312 tty1 4313 4314 tty7 30255 0 pts/1 9712 0 0 0 0 0 20929 14914 15034 However, running the following , to try to find the pid for the tty1 process, gives; mac@tootoo:~/source/procps-3.2.7/proc$ ps aux | grep 4313 mac 15524 0.0 0.0 2988 768 pts/1 R+ 10:42 0:00 grep 4313 mac@tootoo:~/source/procps-3.2.7/proc$ This is obviously wrong, utmp still has the old process id's associated as being logged in.
