Agetty fails to start after switching out of single user mode

Every time I switch to runlevel 3 from single user mode, agetty fails with this error:
Jan 29 10:19:28 localhost agetty[1445]: /dev/tty1: cannot open as standard input: Input/output error
And since it fails, init disables it for 5 minutes… This always happens on the virtual console I run "init 3" on; the other consoles work fine.
This is how I run agetty from /etc/inittab:
c1:2345:respawn:/sbin/agetty -8 -s 38400 -a ma --noclear tty1 linux
Disabling auto-login and removing the --noclear option does not make any difference. Does anyone have a clue what is going on? It is more of an inconvenience than a problem, but still… I am using early KMS on an ATI Radeon 9550 card, by the way.

So nobody else has been bitten by this stupid bug?
Anyway, it happens on a pure VGA console too, so it has nothing to do with the video driver. And I take back the “more of an inconvenience” part – it is freaking annoying that one can not just properly change the runlevel. Oh well…

  • Imac won't start up n issues in single user mode

    Imac won't start up after long time 'frazing' of Firefox. Manual start up ended up in the grey screen forever'processing' icon.
    Had a look at other solutions, unable to enter safe mode. Someone mentioned to try single user mode and it went through half way  with error messages on the screen which has no command line available for me to key in any letter.
    My Imac has been out of warranty coverage for a while, how do I know if it's hard ware problems before paying for service?
    Any help would be appreciated!
    Alice

    Yes, I have backed up and deleted old files using target disk mode with an old macbook.  It's just the larger files I didn't have enough space and disks for.  I really appreciate your help on this as I've never had any mac issues before this so am not really sure what to look for.

  • Can't 'reboot' out of single-user mode.

    Went into single-user mode earlier to run fsck. After everything had finished, and a couple of minor things repaired, typed in 'reboot' and... nothing happened. There didn't seem to be a prompt anymore to accept an input. I eventually just used the master switch. This was the first time I'd tried this since updating to Tiger. Is this a Tiger thing?

    reboot is not what you type at single user mode. That is not a Unix command. In single user mode you type:
    /sbin/mount -uw /
    followed by
    exit
    or
    logout
    to leave it. You may be confusing it with open firmware, which you type:
    mac-boot
    to exit.

  • Get out of single user mode? and get  into the "normal" screen?? pls help!

    Dear Everybody,
    I have removed 2 users from my imac (osx 10.7.4) to create more space and had my main user still on the system.
    after i restarted the system. a white screen came up? I had no idea what to do. After some checking i think i am in single user mode since there is only 1 user for the computer. PLEASE: how can I go from this white screen (single user) back to my normal log in so I can possible add 1 more user?
    I have no idea what to do so pls help
    Thanks

    MANY THANKS IN ADVANCE! I need a fast solution since i need my files urgently for work.

  • Start vm linux Guests in single-user mode

    Hi -
    I have OBIEE vm template installed and everything is OK, I forgot the roor password for this guest, (ovsroot) is not working I think I've changed it. One option is to start this guest in single-user mode, I tried but you can't see the console until the system is starting services which is a late phase to run linux single command on boot prompt. Please advice how can change my root password using single-user mode.
    thanks in advance

    Sorry, but I am not sure I am getting this right, where should I add 'single console=xvc0', if you mean the guest, as I mentioned in my post I don't know the root password and I can't logon. please kindly if you can add more detailed steps.When you boot your guest using xm create -c vm.cfg, it will immediately connect you to the console of the guest. That will show you the GRUB boot menu. You then need to edit the kernel boot line exactly the same way you would a physical server. In order to boot into single-user mode, you need to add the parameter single to the boot line. Along with that parameter, you also need console=xvc0 so that the guest uses the connected console to show you the boot process and allows you access to the single-user shell. If you do not use this parameter, you'll need to determine the VNC port used by the guest and used VNC to connect to the console instead.

  • Start SQL Server in single user mode with parameter -m doesn't work well

    The SQL Server (MSSQLSERVER) service was started successfully.

    As you can see, I'm still able to connect with sqlcmd prompt to SQL Server. According production doc of SQL Server 2014, it should not be conncting by sqlcmd. it shall only be connected by SSMS.
    below the original doc on msdn:
    Start SQL Server in Single-User Mode
    Provide Feedback
    Under certain circumstances, you may have to start an instance of SQL Server
    in single-user mode by using the startup option -m. For
    example, you may want to change server configuration options or recover a
    damaged master database or other system database. Both actions require starting
    an instance of SQL Server in single-user mode.
    Starting SQL Server in single-user mode enables any member of the computer's
    local Administrators group to connect to the instance of SQL Server as a member
    of the sysadmin fixed server role. For more information, see Connect to
    SQL Server When System Administrators Are Locked
    Out.
    When you start an instance of SQL Server in single-user mode, note the
    following:
    Only one user can connect to the server.
    The CHECKPOINT process is not executed. By default, it is executed
    automatically at startup.
    Note
    Stop the SQL Server Agent service before connecting to an instance of SQL
    Server in single-user mode; otherwise, the SQL Server Agent service uses the
    connection, thereby blocking it.
    When you start an instance of SQL Server in single-user mode, SQL Server
    Management Studio can connect to SQL Server. Object Explorer in Management
    Studio might fail because it requires more than one connection for some
    operations. To manage SQL Server in single-user mode, execute Transact-SQL
    statements by connecting only through the Query Editor in Management Studio, or
    use the
    sqlcmd utility.
    When you use the -m option with sqlcmd or
    Management Studio, you can limit the connections to a specified client
    application. For example, -m"sqlcmd" limits connections to a
    single connection and that connection must identify itself as the
    sqlcmd client program. Use this option when you are starting
    SQL Server in single-user mode and an unknown client application is taking the
    only available connection. To connect through the Query Editor in Management
    Studio, use -m"Microsoft SQL Server Management Studio - Query".
    Shawn

    Hi Shawn Xiao,
    For starting SQL Server instance in single user mode, we can add –m; parameter in SQL Server Configuration Manager, also we can run CMD with ‘Run as administrator’ and input the following statement.
    NET START MSSQLSERVER /m
    I do a test in SQL Server 2014 Express version, after starting SQL with Single User Mode, SQL Server will only accept one connection. If you connect to SQL Server with a user account, the following error will occur.
    Login failed for user ‘domain\username’. Reason: Server is in single user mode. Only one administrator can connect at this time.
    However, in your situation, you can connect to SQL Server and run T-SQL statement successfully, it can be due to connection with the administrator account in your sqlcmd.
    For more information, you can review the following article.

  • Single user mode session lost after backgound processes jump in

    We have an application running on SQL server. This application restores DB very frequently using Single user mode. Following are the SQLs that are executed to restore the database in single user mode and to get the database back in multi user mode.
    alter database [test-db] set single_user with rollback immediate; --This sql is run using test-db
    use master;restore database [test-db] from database_snapshot = 'snapshot_test-db';
    alter database [test-db] set multi_user;
    After switching the test-db to single user mode some 4-5 background processes of Taskmanager jump in for the test-db kicking off the session that application has taken over in single user mode . These background process are deadlocked between them selves.
    Please refer to the output of sp_who2 below at link.
    http://social.microsoft.com/Forums/getfile/200625
    and following is the deadlock XML.

    On searching for this problem I found out that people have faced similar problem but I was unable to find out the root cause and debug steps for this problem. Stopping the SQL server is provided as a solution to kick out these background processes but this
    is not a feasible in our case as code to restore DB runs very frequently resulting in this problem at a good frequency.
    I also made sure that SQL Server Agent is not running. The SQL services running on server are SQL server, SQL Server Browser and SQL Server VSS Writer.
    Any help will be appreciated as this is a blocker problem.
    Thanks,

    Hi Amrita,
    We can open a transaction, make data modifications to generate a lot of transaction log, and then run ALTER DATABASE AppDB SET MULTI_USER in the same transaction. You can also refer to the following document:

  • Kernel panic on MacPro in Single-User mode after memtest.

    I've had about 7 kernel panics in about 7 days on a new MacPro. 2 gigs of RAM (Apple Installed). Fresh install of OSX (no user import). While going through the troubleshooting process I ran memtest in single user mode. Ran it all night no errors.
    So in the morning I typed ctrl-c and then exit (i think)... it seemed to start the process of booting and I got another kernal panic. I've actually done this three times now.
    I checked panic.log and all the error messages but 1 were the same. Including the ones I got in single-user mode (copied below).
    Should I be able to gracefully exit out of single-user mode without a kernel panic?
    Does this point to a RAM error even though memtest and AHD for that matter ran all night without finding anything?
    I'm all set to try again (taking careful notes this time) to see if I can reproduce but I was hoping for some feedback first.
    Thanks,

    Welcome to Apple Discussions!
    Yes, your memory or memory slot, or memory seating is bad or off. "Uncorrectable Fbd memory error detected. ferr = 20000000 , nerr == 00000000, fErrFat = 20000000 nErrFat == 00000000"
    Clearly a memory related issue. It may also be that memtest doesn't know how to diagnose the new kind of memory and is reporting that back to the logs. Take it in to a service center to have all the boards replaced to make sure the issue isn't reproduceable with new memory. If it is, then I'd consider the slots on the logicboard a problem.

  • Is there a way to switch to single-user mode for screen sharing in Lion?

    Hello,
    with the new multiple user mode one screen sharing guest can not see the mouse cursor of another - even if they use the same login.
    It's a pity, because we use screensharing to discuss the content of the screens with multiple screen sharing users.
    It is necessary to point with the cursor to show the other members of this 'screen sharing meeting' things while discussing.
    This is not possible anymore with Lion and multi user screen sharing.
    Does anybody know a patch or terminal command to switch back to single user mode for screen sharing?
    Kind regards

  • ColdFusion 8 Fails to start after update Java for Mac OSX 10.5 Update 4

    I have been using ColdFusion on a Mac for years. Now CF fails to start after I updated Java for Mac OS X 10.5 Update 4. I usually start by typing in the terminal window sudo /Applications/ColdFusion8/bin/ColdFusion start.
    There is a crash report but I don't know how to read it. See attached.
    Please help, I need this working for my job.
    Thanks...Colin

    Dear Craig,
    Macbook Pro 2.4GHz Intel Core 2 Duo 4 GB RAM
    I'm sure that this is 64-bit
    CF 8.0.1 Enterprise Build 3080
    I had moved the Java SE 6 to the top in both Plugin and Applications. The
    correct version is showing in the terminal window. See below.
    Last login: Thu Jun 18 11:27:09 on ttys001
    Beta-4:~ Colin$ java -version
    java version "1.6.0_13"
    Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211)
    Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode)
    Beta-4:~ Colin$
    CF will not start. I have the activity monitor open, and when I start CF you
    see it in the activity monitor for a few seconds as it starts up. When the
    message process is completed in the terminal window CF disappears in the
    activity monitor.
    Any suggestions?
    C
    Hi, Colin,
    My apologies but I forgot to ask 2 questions: (1) What kind of Mac you have
    (Intel or PowerPC)? (2) What version of CF are you running and what installer
    did you choose (8 or 8.0.1, 32-bit, 64-bit, etc.)?
    To start, try the following:
    1. Normally you'd shut CF down first ... but that's not necessary for you
    2. Open Java Preferences again
    3. Select Java SE 6 and move it (drag) to the top spot in both section (Applet
    Plugin and Applications)
    4. Open Terminal
    5. Type java -version (you should see 1.6.0_13 as the new version)
    6. Try to start CF again
    This may not work (I've had issues with it) but it's technically how it's
    supposed to work. With the Java Preferences utility, you're visually setting a
    default JVM (you can do it with commands in Terminal but this is much faster
    and easier).
    If CF still won't start, look for the jvm.config file in your CF application
    folder (try /Applications/ColdFusion8/bin or
    /Applications/ColdFusion8/runtime/bin -- the latter is where a jvm.config file
    is on my machine for a particular version of CF that's installed similar to
    yours). You can override the JVM in this file but, hopefully, that won't be
    necessary!
    Best,
    Craig

  • Multiple Oracle Homes - Oracle Listener failes to start after installation

    Just in case the listener fails to start after an oracle installation, please check the oracle ports in the listener.ora and tnsnames.ora, both of which are present in the following directory:
    ...\oracle\<SID>\<Ver>\NETWORK\ADMIN
    All installations should have separate listener ports eg. If the first installation has port 1527, the next one should be 1528 and so on..
    If they do not, manually change the ports and start the listeners.
    Also check SAP Note 98252. Although I didn't find it necessary (I think it applies only if you have a single listener for all oracle homes), it did give me an idea that there some config problem in the .ora files.
    Also see [this thread|Oracle Listener error in Import ABAP phase?; for related details

    For SID = globedb the same name i have given
    for sys ,i have given sysdb as password
    and for system i have given systemdb as password
    with this can i do anything

    if i want to login to the scott

    Judging by all the posts on the forum, there seems to be an issue at Apple's end, although they have made no announcement on their status page. Some users have reported that Apple is aware of the issue.
