• "Serious errors found HF checking the drive for /home" After Moving /home to external HFSplus partition

  - by Arctic Shadow

  I just installed Mac OS X 10.7 "Lion" and Ubuntu 11.10 on my MacBook Pro. Using these instructions: tuxation.com/creating-home-partition-mac-linux.html . After changing the location of my home folder to the new location, it gives me the error in the title, and my username no longer appears in the login screen. Using the "Other" option with my username seems to make it try to log in, but the screen quickly flashes between blank and a shell before kicking me back to the login screen without notice. I'm trying to share my home folder between Mac OS X and Ubuntu, using an hfsplus partition (unjournaled) between the two. The home partition seems to mount fine as /home, and I am able to modify it under Ubuntu. Below is the line I've added to fstab: /dev/sda3 /home hfsplus defaults 0 1 I should also note that I changed my account's username and home directory location to match this, though I've double checked that and everything seems in order there... Thank you in advance for any assistance. Edit: It seems that the /etc/passwd file didn't have my new home directory's location in it, so I changed that, and I am now able to log into my account, although I am still not listed in the login screen, and my username in the menu on the top right shows up as "[Invalid UTF-8]"...

• Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

  - by Jake

  I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

• Radeon HD5670 hangs after login

  - by pKaresz

  Thanks in advance for your advices. I installed, Ubuntu 12.04 today, on my PC with a Radeon hd5670 graphics card. The first error I encountered, (just like the first time Unity came out - after witch I waited to try Ubuntu again until now) is, that it hanged after login at the desktop wallpaper, with only the mouse cursor. Well actually the first problem was with the live CD, but I managed to install it, using the install now, not the try now. Live CD has the same problem, as after install. So, after installing and getting the error, I searched of course before asking this:) I found this: Ubuntu hangs at purple screen The accepted answer there helped me to get to this. (note, that the below picture is a screen taken from a working desktop, and then erased the parts that don't show on mine.) Note that there is nothing at the top except the brown bar. No shutdown button, no nothing. The system hangs, I can't click on anything, I can only wiggle around with my mouse XD

• Ubuntu Crashes @ Login Screen

  - by Peter

  So, I've been having troubles with the newest Windows Installer for Ubuntu Desktop(http://www.ubuntu.com/download/desktop/windows-installer). When I start up up the operating system, i enter the login screen of Ubuntu. Everything is fine at that moment except my mouse and keyboard are frozen. Next I hear a "bongo" noise which is obviously the system looping and getting ready to crash. Soon enough, I enter a purple screen with white diagonal short lines in the background. I am then forced to unplug my desktop. Any way to fix this? Thanks!

• Installed without the usual menus. Now I can't log in

  - by Martha

  I tried to install from CD. The computer wouldn't boot from the CD, so I clicked on the 'boot helper', and rebooted the machine. And the first thing I see is do I want to open Windows or Ubuntu (without it asking me whether I wanted to install it alongside Windows or replace it), and when I click on Ubuntu, after a very long time, I finally get a login screen. But I don't have a login, because I never set one up. Help!

• Linux, how to capture screen, and simulate mouse movements.

  - by 2di

  Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

• S.redirectTo leads always to a blank screen

  - by Jaime Ocampo

  I am now playing a little bit with lift (2.8.0), and all the features in LiftRules work as intended. But I haven't been able to use S.redirectTo at all. I always ends with a blank screen, no matter what. No error messages at all! As an example, I have the following form: ... <lift:logIn.logInForm form="post"> <p><login:name /></p> <p><login:password /></p> <p><login:submit /></p> </lift:logIn.logInForm> ... And the code is: object LogIn extends helper.LogHelper { ... def logInForm(in: NodeSeq): NodeSeq = { var name = "" var password = "" def login() = { logger.info("name: " + name) logger.info("password: " + password) if (name == "test1") S.redirectTo("/example") if (name == "test2") S.redirectTo("/example.html") if (name == "test3") S.redirectTo("example.html") S.redirectTo("/") } bind("login", in, "name" -> SHtml.text(name, name = _), "password" -> SHtml.password(password, password = _), "submit" -> SHtml.submit("Login", login)) } } The method 'login' is invoked, I can check that in the log information. But as I said, no matter which name I enter, I always end with a blank screen, although 'examples.html' is available when being accessed directly in the browser. How should I invoke S.redirectoTo in order to navigate to 'examples.html'? Also, why don't I receive an error message (I am logging at a debug level)? I think all the configuration in Boot is correct, since all LitRules examples (statelessRewrite, dispatch, viewDispatch, snippets) work fine.

• What could cause these "failed to authenticate" logs other than failed login attempts (OSX)?

  - by Tom

  I've found this in the Console logs: 10/03/10 3:53:58 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:53:58 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:00 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:00 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:03 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:03 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). There are about 11 of these "failed to authenticate" messages logged in quick succession. It looks to me like someone is sitting there trying to guess the password. However, when I tried to replicate this I get the same log messages except that this extra message appears after five attempts: 13/03/10 1:18:48 PM DirectoryService[11] Failed Authentication return is being delayed due to over five recent auth failures for username: tom. I don't want to accuse someone of trying to break into an account without being sure that they were actually trying to break in. My question is this: is it almost definitely someone guessing a password, or could the 11 "failed to authenticate" messages be caused by something else?

• Can I send some text to the STDIN of an active process running in a screen session?

  - by Richard Gaywood

  I have a long-running server process inside a screen session on my Linux server. It's a bit unstable (and sadly not my software so I can't fix that!), so I want to script a nightly restart of the process to help stability. The only way to make it do a graceful shutdown is to go to the screen process, switch to the window it's running in, and enter the string "stop" on its control console. Are there any smart redirection contortions I can do to make a cronjob send that stop command at a fixed time every day?

• How to get Mac OS X Terminal.app and screen/vim scrolling to play nice?

  - by rustychains

  OSX 10.6.3 Terminal.app Am a pretty dedicated screen user. Terminal.app line buffer and/or scroll does not seem to work for me. That is while in screen anything that goes past the top of the frame is gone, can't scroll back to. This seems to work ok in other terminal apps gnome, cygwin. Perhaps this is a shell env, config, or command? .screenrc: startup_message off autodetach on shell -$SHELL vbell off defutf8 on caption always caption string "%{= wk}%w" I have tried using defscrollback here with different values, but doesn't have an effect. some .bashrc settings: set -o physical export TERM=xterm-color shopt -s checkwinsize

• Compaq nc4200 screen cutting out and keyboard lagging after dropping - could I repair this?

  - by Holly Gray

  I have a HP Compaq nc4200 laptop. I got it from a family member who no longer needed it, who got it from a sale of old office equipment, so it's at the very least third-hand, and somewhat battered. Today, I dropped it. It seemed unharmed at first, but the screen cuts out every few minutes (sometimes seconds), then fades back. Keyboard input also occasionally starts lagging, as does the mouse. It might be a coincidence, but, oddly, it seems as if, when the screen cuts out, it comes back sooner if I use the trackpad. Is this something that I could fix? What might be causing it?

• Screen resolution of monitor is wrong every time I turn the computer on?

  - by utahco

  Hi, Im just wondering if there is a solution to my weird problem. Every time I turn on my PC the viewport isn't aligned correctly on the screen - there is always a black strip on the right hand side. This is not a big issue as it can be resolved by pressing the menu button on the screen and doing a factory reset. However it is irritating having to do it every time. The weird thing it never used to happen before with the tower Im using. Is potentially out of date drivers a problem? Thanks.

• How can I disable interactive login for all the members of an active directory group?

  - by Jeremy Hutchinson

  I have a group of users that I'm setting up as test users. I want to make it so that no one can log onto the domain with these accounts, but they need to have active exchange mailboxes since this is what I am testing. I put all the test users in the same group. Can I set a security policy that will do this?

• Snow Leopard Hangs at Login Window

  - by jessecurry

  I've had an issue for the past few months, but I rarely restart so it hasn't caused too much trouble. Basically, when I start up my Mac (iMac10,1 - 3.06GHz Intel Core 2 Duo, OS X 10.6.3) everything proceeds as usual until I reach the login window. The login window displays normally, but keyboard and mouse input seem to be ignored. This condition persists for around 5 minutes at which time everything goes back to normal. While the login window is frozen my second monitor appears entirely blue, the second monitor receives a background as soon as the login window becomes responsive. If I startup while holding SHIFT the problem still occurs, but the freeze is much shorter. Looking through my logs I see no activity during the time that the login window is frozen. I've attempted to repair disk permissions, and gone through every possible maintenance option in Cocktail.

• LDAP: Need login of application/servers from a certain group only

  - by Geo

  We need to configure LDAP for login to different servers and applications. We have created all users and different groups as follows: dn: dc=ldapserver,dc=local dn: ou=people,dc=ldapserver,dc=local ou: people dn: uid=geo,ou=people,dc=ldapserver,dc=local dn: uid=user,ou=people,dc=ldapserver,dc=local dn: ou=groups,dc=ldapserver,dc=local dn: cn=server,ou=groups,dc=ldapserver,dc=local member: uid=geo,ou=people,dc=ldapserver,dc=local dn: cn=website,ou=groups,dc=ldapserver,dc=local member: uid=user,ou=people,dc=ldapserver,dc=local We need scenario in such a way that the users that are member of server need only login to server (that is geo) and users that are member of website need only login to websites (That is user “user”). Please let me know how we can configure it. For login site we tried by giving DN as cn=website,ou=groups,dc=ldapserver,dc=local and Login Attribute as uid and also member but it is not working. Can anyone please help us on it. Also please let us know is there any other option for accomplish this scenario. Thanks Geo

• Windows 8 Metro/Modern Start Screen with Multiple Monitors -- Keep it always maximized?

  - by Jersey Dude

  Before installing Win 8 today, my plan was to keep the Metro UI up on my smaller, laptop monitor and have the classic UI running on my two larger monitors. However, in reality, as soon as I click on something in one of the classic UI monitors, the Metro UI minimizes (thus exposing the classic UI in its place). Is there any way to keep the Metro UI from minimizing when I do something in another monitor? Oddly enough, if there is an app running/suspended in the Metro Window, then the Metro UI is not minimized. If the Start screen is currently viewed, clicking in a classic window/monitor switches the Metro UI from the start screen to the last run app. Very peculiar..

• Is there a fix for an iMac G5 annoying screen pattern issue?

  - by smountcastle

  It's probably a hardware issue, but I was hoping that someone might know of other options to try. My iMac G5 (the revision just before the built-in iSight was introduced) has developed an annoying pattern of short/wide rectangles in a pinkish hue across the screen. I've followed Apple's instructions to ensure that the logic board hasn't failed (by resetting the SMU and watching the internal LEDs light-up). I suspect either the LCD or video card has failed. Below are two screen shots, one taken by my iPhone which exhibits the problem and a snapshot taking from the faulty iMac which looks fine.

• How do I know I'm running inside a linux "screen" or not?

  - by Jun Chen

  The "screen" refers to a program mentioned in How to reconnect to a disconnected ssh session . That is a good facility. But there is a question I'd really like to know. How do I know whether I'm running inside a "screen"? The difference is: If yes, I know I can safely close current terminal window, e.g., close a PuTTY window, without losing my shell(Bash etc) session. If no, I know I have to take care of any pending works before I close the terminal window. Better, I'd like this status to be displayed in PS1 prompt so that I can see it any time automatically.

• Ubuntu 14.04: After login, top- and sidepanel don't load and system settings don't open

  - by Löwe Simon

  I have Ubuntu 14.04 on a Medion Erazer with the Nvidia GTX570M card. At first, while I had not installed the last nvidia driver, each time I would try to suspend my pc it would freeze frame on the login. Once I managed to install the nvidia drivers, everything seemed to work up until I noticed that suddenly the system settings would not open anymore. I then rebooted my pc, but when I logged in I just end up with my cursor but no top panel or side pannel. Thankfully, I had installed the gnome desktops which works, except for the fact the system settings do not open also in the gnome desktop. I have tried following: Problems after upgrading to 14.04 (only background and pointer after login) except for reinstalling nvidia, since then I would be back at square one with suspend not working. When I try to launch system settings through the terminal, I get: simon@simon-X681X:~$ unity-control-center libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast (unity-control-center:2806): Gdk-ERROR **: The program 'unity-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 229 error_code 16 request_code 155 (GLX) minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I know the 2 problems seem unrelated, but since they occured together, I am wondering if that is really the case. Your help is much appreciated, Simon

• 10.10 boots to command line login prompt

  - by greggory.hz

  I recently installed Ubuntu 10.10 on a computer that was previously running 10.04 (that worked fine). Now, each time I boot up, it starts up in a command line login prompt. I can login and it stays at the command line (as expected). I can then manually start gdm with sudo start gdm and it works fine. I can also enable compiz (using proprietary nvidia drivers) so I'm reasonably confident that it's not a driver problem (at least not in the sense that the drivers just flat out aren't working). Interestingly, if I leave it at the command prompt without logging in, after about 5 or 10 minutes, gnome starts up on its own. I'm not sure what is causing this. This is what dmesg | tail gives me after a manual start of gdm: [ 15.664166] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 270.18 Tue Jan 18 21:46:26 PST 2011 [ 15.991304] type=1400 audit(1297543976.953:11): apparmor="STATUS" operation="profile_load" name="/usr/share/gdm/guest-session/Xsession" pid=990 comm="apparmor_parser" [ 16.606986] eth0: link up, 100Mbps, full-duplex, lpa 0xCDE1 [ 18.798506] EXT4-fs (sda1): re-mounted.

• How to mount private network shares on login?

  - by bainorama

  I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?

• Mozilla Persona to the login rescue?

  - by Matt Watson

  A lot of website now allow us to login or create accounts via OAuth or OpenID. We can use our Facebook, Twitter, Google, Windows Live account and others. The problem with a lot of these is we have to have allow the websites to then have access to our account and profile data that they shouldn't really have. Below is a Twitter authorization screen for example when signing in via Technorati. Now Technorati can follow new people, update my profile and post tweets? All I wanted to do was login to Technorati.com to comment on a post!Mozilla has just released their new solution for this called Persona. First thought is oh great another solution! But they are actually providing something a little different and better. It is based on an email address and isn't linked to anything like our personal social networks or their information. Persona only exists to help with logging in to websites. No loose strings attached.Persona is based on a new standard called BrowserID and you can read more about it here:How BrowserID Works.  The goal is to integrate BrowserID in to the browser at a deeper level so no password entry is required at all. You can tell your web browser to just auto sign in for you. I am really hoping this takes off and will look at implementing it in current projects! I would recommend researching it and lets hope it or something like it becomes a wide spread reality in the future.
