Sometimes my Ubuntu keeps hanging when Unity crashes, or due to some other reason.
Logging out and logging in again seems to solve this problem, but sometimes I cannot even access the terminal from the Desktop.
Is there any command that I can use from the console so that my session at the desktop environment ends and I log out?
I already tried gnome-session-save --logout but it doesn't work
when ever someone uses the log off option it always brings up a black screen that is only fixable by a hard reset. however when switch from or selecting a name to switch to works fine with no errors. is there anyway to fix this? im using lucid 10.04
View 4 Replies View RelatedI work for a public school and we are implementing a number of Ubuntu NBR 9.1 netbooks. I wanted to use Likewise Active Directory for authentication, but have problems with the software so now I'm onto another solution for our problem.
We are going to have one login for all users (Students, is the name). The problem with this is that Website passwords can inadvertantly be stored, potentially compromising users personal data. Additionally, I don't want to have any files left in the Students profile in case people accidentally save personal information in their files.I'm thinking there are potentially two solutions:
1. The Students profile is deleted when the user logs off. This will erase web history and files
2. The Students account is always logged in with a temporary profile (or no profile, if that is possible) that deletes itself at logoff because it is temporary.
I'm having a hard time coming up with search terms for a solution like this, so I thought I would put the question to the experts.
I've setup pam_usb to allow me to log in with just my usb drive. This works fine, save for one issue. When I log in using pam_usb, my session dies abruptly if I unplug the usb drive.I am _not_ runing pamusb-agent.It seems like there may be some issue with policykit, but I'm not sure./var/log/auth.log:

i block my screen (glmatriz screensaver), and go sleep or lunch, and when i get back, i have to logon again, and all my applications have been killed. the weirdest thing is that this does not happen everytime, but i cannot find a pattern to the times that happens.i pretty sure that the machine is not rebooting, cause my uptime still intact.some data: ubuntu lucid (upgraded from jaunty) x86, system all up to date. hardware is a desktop dell vostro 220n (intel chipset, 2gb memory and a pentium e5400.

View 1 Replies View RelatedI am using Ubuntu as the client machine operating system. I have a start up program to connect to a Windows terminal Server. I am needing assistance in how I can force the client to logoff if the terminal connection is terminated for any reason. This is more of a security issue as we do not want the students using the computer to access the loacl machine at all. The program works great on boot, but it shows the home screen when terminated.

View 9 Replies View RelatedAfter upgrading from 10.10 to 11.04 my laptop starts hanging after lock the screen & also some time it is getting log off automatically while working.
It is really strange as all the work is getting lost in mean of working, is some one has faced such issue.
What is the probable solution for this, any idea ?
I can use this at the end of bash_profile to autorun start x after logging on. code...
But what about to auto logout after killing the X session? I hit exit from fluxbox, but I could add a menu item I suppose to just kill the xsession. Wondering if there is a graceful way to do it with bash_profile.
Also, on a related note, if I switch to dash with the bash_profile method still work?
I'm running OS 11.3x64, KDE 4.5.
After running updates yesterday (Friday) now the Shutdown and Log Off buttons don't work in KDE. This happens with the taskbar buttons, and in the Leave menu. The only way out now is to ALT+F1 into a console, log in as root, and run shutdown. The system will shutdown at that point, but it's pretty inconvenient. I'm using the login manager that installs with KDE (can't remember the name) since Gnome was installed as a secondary desktop.
Where can I put commands which should be executed just before
- logoff
- shutdown
I think there must be somewhere an opposite script to
.initrc
or
.bashrc
When i try to start compiz-fusion the system logoff.
I use fedora 11.

Commands as root works well when normal user is logged in and connected to net via KDE 4 network manager, but after logoff network is gone. And it is impossible to get it back because command mentioned above stops working!

View 2 Replies View RelatedYesterday i fell asleep while my laptop was still on. when i woke up this morning i stared at a black screen. I tried to wake it up but nothing happened so i just turned it off.
But when i turn it on again i get this after the login screen: Xsession: Warning" Unable to write to /tmp; X session may exist with an error
After a few minutes i get the message, that my temp directory id full.
Now the problem is, that i cannot even login in console mode! i tried the "console login" mode from the login window, i tried switching the console with ctrl+Alt+F1, i even tried to start in recovery mode. But all i get is a blank screen with a blinking cursor in the middle, but i can't write anything!
There is this [URL] but unfortunately, it is under X11. A console based one for Linux, does it exist?

View 6 Replies View RelatedAfter 10.04 upgrade I cannot drop to console, as well as the gnome UI takes overly long to load, letting me stare at my background for 10 seconds before arriving.Let me start off by saying my machine would not even boot when using the nouveau driver. After successfully installing the normal nvidia driver I was then able to get to my desktop.I cannot view any of the console's that are not using X(F1 F2 etc) None of these work, previously I received invalid input on the nouveau driver but now when i drop to console I am met with a black screen and no display until I return to the one using X.
I suspect it is using an impossible resolution with the consoles but I cannot figure out how to fix it. grub seems to be ignored for display resolution.I am using a TV/monitor that is 1360x768 @ 60hz
I removed gdm and kdm and my laptop started in console mode.Now I would like to get same thing - I made upgrade to ubuntu 10.4 and it starts again in graphics mode. I removed from grub menu.lst splash and quit, removed gdm and kdm - and again I receive graphics prompt.PS I removed also failsafe-x.
View 6 Replies View RelatedI really don't know what to make of this. I have just installed Lucid Server onto my first generation Mac G5 (1.6 uni). The install went fine & the system rebooted...
The first problem:
Fatal errors encountered installing thermal control. All the windfarm modules failed, but judging by the fact the mac doesn't sound like a jet engine, thermal control /is/ working.
The second problem:
After this, it brings up the splash screen & then the console goes dead. No keyboard, no display, no nothing; it looks like the system has hung. But... SSH is working. The system is up and as responsive as it should be!
I've tried adding video=ofonly to yaboot.conf and zapping the pram, but it made no change.
I have a very strange trouble with gnome/X11/Adapter/memory, I really don't know! When I upgrade my memory to 2Gb (1Gb+1Gb), graphic mode not starting! Load only console, but gnome not load. And besides error message not showing. 'starx' command leads to black screen and nothing happends, keyboard doesn't work too. if I leave 1Gb memory, all working perfectly! tell me where I can find log-message or how I can solve that problem. In /var/log I can't found anything interesting.

View 1 Replies View RelatedNot the gnome-terminal fonts... That's easy... How about the font faces on tty1-6? I tried Slackware once... It was way back in my Linux experience so it struck to me as a clumsy and ill-managed operating system despite that the fact is the exact opposite... Well, as it appears, Slackware did have something about changing the console font since it mostly focused on terminal, you know, it booted up in terminal by default, for starters. Anyway, since Ubuntu is Linux as well, I guess there must be some way of changing the font face for the terminals, eh?
View 3 Replies View RelatedI have been running Ubuntu 10.04 on my laptop just about since it came out.Prior to that I was running 9.10 on the same laptop. I was so happy with 9.10 I thought I could only be happier with 10.04.I was wrong.There are some things about 9.10 that I have *lost* in the transition to 10.04.These bother me quite a bit so much so that I have repeatedly considered going back to 9.10.Please keep in mind this all worked fine under 9.10 on exactly the same hardware.
1) When I connect the external VGA port on my laptop to my 32 Samsung TV it comes up as a 40 Samsung TV and it is impossible to set the correct resolution.This makes watching TV over the Internet via my notebook impossible (I used to use URL... and others).
2) I cannot change the resolution on the console (the TTY's 1 to 6). It used to come up as standard old fashioned VGA (80 columns by 25 rows of text) but now it is much smaller font and much larger console.The VGA= in GRUB does nothing. And this is the only suggestion I seem to be able to find. From my reading most people seem to like the large console w/ small font.I dislike it for the reason I will get into next
3) DOSEMU locks up my computer with a blank screen when running in super mode on the console.Pressing Ctrl+Alt+F# accomplishes nothing and either does Ctrl+Alt+Del.I have to press and hold the power button forcing a hard shutdown (at least this is the only solution I have found).
My problem is that I am trying to install an Nvidia driver on ubuntu 10.04, and I can not access my console mode by pressing ctrl alt f2. When I press that keystroke my cursor will disappear till I press alt f7.
