Fedora :: Preventing KDE App From Restarting After Reboot / Login
Jul 5, 2010
I'm running F13 with KDE 4.4.4 on my desktop PC. A few months ago I had occasion to run Kalarm (invoked via "Kickoff" app launcher). Ever since that time, the Kalarm icon appears in my KDE "system tray" after I login. I power down my PC when I'm finished using it for the day.In an effort to get rid of the Kalarm icon, I changed my KDE "session manager" (System settings -> Advanced -> Session Manager) settings to: "on login: start with an empty session". But the Kalarm icon still appears in my "system tray" after the next reboot/login.I've also tried right-clicking on the Kalarm icon and selecting "quit". The icon still re-appears after the next reboot/login.Why didn't the session manager setting: "on login: start with an empty session" get rid of the Kalarm icon?
yesterday i installed slim login manager on my computer (eee pc 1018p, ubuntu 11.04), and now it cannot get passed the ubuntu loading screen (with orange dots underneath) when booting. i tried booting into recovery mode and that didn't work either. i also left the computer trying to boot overnight and that didn't work. basically, during this loading screen that should eventually bring you to the login screen, i can alt+tab to see the progress of the load. the progress is stuck on
Is there anything I can do from grub to remove slim?or, is there any way I can access my ubuntu partition and save all my files?
I have a headless Jaunty server that I need to access from both mac and PC clients. If the server has been rebooted, I can SSH into it, but I can not VNC into it unless I unlock the keychain. The problem is that I can't figure out how to unlock the keychain from SSH connections, so the only available method is to attach a keyboard to the physical box and enter the keychain password at the server itself.Is there a Terminal command that I can use to unlock the keychain? I have seen references to the 'security' command but that appears to be unavailable to Jaunty?
Is there an even better method than a Terminal command? I don't want to be putting passwords into the Terminal log if I can help it. Ideally, I would connect via SSH, confirm the keychain somehow, and tunnel in through VNC.
fairly new to linux and tried Slack as a way to force myself to learn. I am running current and when i issue the reboot command it will hang on "Restarting system". If i use the shutdown -r now command it will reboot fine. Any ideas?
I removed my .gnome and .nautilus folders and .notifier file. it is working now. I do not know exactly which of these 3 fixed it but I hope this might help someone else!I have some major issue with nautilus which is preventing me from loogging in into my system which is kind of criticle this weekend.I'm running Squeeze with latest updates.
The problem:Today gnome gave some problems caus my taskbar was suddently gone. I couldn't get it back to i reinstall gnome-desktop and updated my whole system. At the update some yes/no questions on a blue screen asking me to restart cups etc had corrupted yes/no buttons. Weird character sets were shown. Well that can happen sometimes i thought.After reinstalling gnome i can't login anymore. My screen keeps flashing while it shows the loading icon of the mouse.Anyone got suggestions? I can't find similar problems on the internet, only problems that happen while already logged in. In my case the segfault prevents gdm starting! Maurice
I've had a couple Ubuntu 8.04 servers hang hard with no terminal response.
After a given time the terminal login screen will go blank automatically. I'd like to prevent that from happening in order to hopefully catch any messages that get output to the screen before these hangs occur. Currently when the server hangs, I can mash the keyboard all I want, the screen stays blank.
I've tried 'setterm -powersave off -blank 0', but that doesn't seem to hold after logout.
I got a prompt for an update so I went thru with it. I restarted my PC but it wont boot up. I keep getting a black terminal screen which asks me for my log in. But when I put it in, nothing happens. I tried to reinstall gdm but it says its already installed.
I have GShutdown 0.2 on ubuntu .when i put it on with some time it is just restarting the session and going directly to login window. "sudo shutdown -P -- --" is working properly so why the GShutdown 0.2 is not??
I just recently upgraded my computer from fedora 11 => 12.After moving /home to a separate partition the installation was very simpel.I only had to reconnect my windows system.BUT a strange problem has started to appear.
1) Booting to grub is no problem at all ( I have configured grub to be able to select windows if I want) 2) I always see the grub count down on my screen. 3) then there is a lot of discaccesses but the screen with the fedora symbol is not seen and then my monitor goes to sleep. 4) I usually(always) have to turn my computer off and try again at least three times before the screen with the fedora-sign is seen. 5) If the fedora-sign lights up I have no problem with login and use of the computer.
There seems to be a very unstable situation between grub and XwindowsHas anyone a solution or at least a explanation?
I'm hosting a server with Ubuntu 10.04. I've stumbled upon a strange problem.The server seems to refuse any login attempts, either with SSH or via a TTY after a reboot. After a couple of minutes (about 10 minutes or so) I able to login. The memory usage isn't high at login nor the system load. The auth.log doesn't show any login attempt before.problem? Or does anybody have a suggestion I could try to fix this?
just a quick question: I have an external HD with 2 partitions, one ext3 and one FAT32.When I plug in the HD both partitions get automatically mounted, but as I only use I use the FAT32 partition to transfer data from/to Windows machines (which does not happen so often) I would like only the ext3 partition to be mounted automatically.
I'm using the Fedora Eee kernel for Fedora 12 (it's an unofficial kernel for the Eee PC), and want to update my system (I just set it up today). How can I update via command line and prevent an update to the default kernel?
I am new using Fedora. When ever I am installing fedora 13, it is not getting ip address. Everytime manually I am opening gui mode for network as system-config-network and then checking activate when system starts option manually. After then if I restart, it is getting ip address. without doing like this, cant we do something like ifdown eth0, ifupeth0 like this so that without restart it takes ip address? Is there any command like this do get ip without restart?
I have a virtualbox installation, and I need fairly high security separation between host and guest traffic. The university network the box hangs off uses statically-allocated ip addresses, allocated to fixed MAC addresses (i.e. it eats any traffic with mismatched ip and MAC addresses).
VBox: 3.0.4 Guest OS: Fedora 11 64bit Hardware: dual NIC, Intel server Bridged networking, with separate NICs for host and guest
I'm aiming for high-security separation between host and guest traffic. To do this, I would like to to run all host traffic through one NIC, H, and all guest traffic through the other, G. The host and guest have separate, statically allocated, IP addresses, IPH and IPG. The network forces these to be mapped to specific MAC addresses, MACH (the address of NIC H) and MACG (the address of NIC G). So it's not too hard to write host firewall rules to enforce this policy. The rules just have to state that traffic coming into H must have a destination compatible with IPH, and traffic going out must have IPH as source - and vv for G and IPG. There also don't seem to be any trouble telling the guest to only use NIC G. As a result, turning off NIC G (or equivalently, firewalling it off from host traffic) crashes the network, I have to reboot it to get networking working.
But I can't figure how to tell the host to _only_ use NIC H for anything else except the guest. Even though we don't see any IPH traffic coming into NIC G from outside, I don't seem to be able to stop the host from starting connections on NIC G. Does anyone know any way to do this - to tell the host that it can only use IPH as its IP address unless traffic is coming from a guest process, and that it can only use address MACH and NIC H? I've been reading route and arp manuals all day, but I can't seem to figure anything on this - mainly because arp and route don't know about host/guest processes, and I guess weren't designed with this in mind...
I'm having trouble booting after a recent bunch of updates (haven't been able to boot F12 from hard disk for a couple of days). The boot process gets as far as "NetworkManager daemon [OK]", then just stops. I get this for all 3 kernels that I can choose from the grub menu (2.6.32.16-141, 2.6.32.14-127, 2.6.32.12-115)Mounting the hard drive with a liveUSB, a quick inspection of /var/log/messages reveals that things go smoothly until: etc. until I hit the power button.I ought to mention that I wireless card that requires the Realtek RTL8192SE driver, which requires
I have a 2 monitor configuration, with the second monitor uses exclusively for mythtv. When I'm not actually watching tv or a muvie or watching visualizations with music playing, I actually use the machine for more productive uses. As the result the second monitor is typically not turned on, might have something to do the the fact it's a crt design, consumes a fair bit of power and does a good job keeping the media room overly warm.
The question is, does Fedora 11 or newer have a means to prevent applications from opening on the second monitor? I've checked the obvious places and nothing jumps out .
btw: According to the nvidia x server settings control panel the second monitor is set up as in twinview mode. This mode was chosen to allow the gpu to do most of the video decoding tasks using vdupau or something as I recall.
is it possible to block an application from using the network? If yes, how? I read it's possible with iptables and with selinux... Also, what about creating a user who can't connect and run the application with that user?
When I'm logged into my account, I can't shut down the computer if someone else is also logged in unless I supply the root password. However, if I log out, I can shut down from GDM without being challenged, even though another person is logged in, which could cause problems if that person is in the middle of some work. Is there a way to password-protect the gdm shutdown function if people are logged in?
I've had an issue in KDE where each time I restart my computer, I get 5-7 notifications that it wasn't able to connect to my ethernet port. (Or something close to that) I think it's trying to connect to my marvell port over and over. Has this happened with anyone else? I think I remember this happening with Ubuntu as well only it only tried to connect to that port once and then stopped trying.
I`d like to find out how to restart USB ports without restarting whole system?I googled some but solutions mentioned were refering to some modules that are not present on F14.
I just downloaded Fedora 15 desktop to a USB device. I am able to boot to the device and load the desktop with errors.I receive the following:
SeLinus is preventing /usr/Libexec/colord from getting access on the blk_file /dev/dm-0 Plugin: catchall Source Process: /usr/libexec/colord Attempted: getattr On this blk_file: /dev/dm-0
I also am not able to use my wireless network. This is being booted on a Dell Inspiron 1545 Vista Sp2 system with 4 gb or RAM.The wireless network connection works fine with Vista.

I had an aging RH 7.3 server that I decided was time to upgrade the hardware and software as well. I chose Fedora 13.This server runs an ircd with several bots connected to it. The bot in question is a perl bot based on the old dreambot script. On the RH 7.3 server, it ran forever. On the new Fedora 13 server, it does an EOF and restarts every hour, exactly one hour after it's been started.Is there something limiting the time that a perl script can execute?
My Fedora box is giving me an SELinux security error:
Code: Summary:
SELinux is preventing the samba daemon from reading users' home directories.
Detailed Description:
SELinux has denied the samba daemon access to users' home directories. Someone is attempting to access your home directories via your samba daemon. If you only setup samba to share non-home directories, this probably signals an intrusion attempt. For more information on SELinux integration with samba, look at the samba_selinux man page. (man samba_selinux)
Allowing Access: If you want samba to share home directories you need to turn on the samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"
I have a weird problem. When I restart/reboot, the computer restarts (I see the BIOS, Grub, etc., sequences) and goes right back into my desktop session - no login required. This is not the behavior I want.How can I make it reboot to the login screen?I'm running Ubuntu 10.10 Maverick
I have Ubuntu 10.10 Gnome. My computer automatically boots up at a particular time of day. But it stops at the login window. 1) How do I let it automatically login? I have set passwordless login.So when I manually hit my login username, it logs in without needing me input password. But it gives a pop-up window asking for keyring password. 2) How to get rid of it?
I went to print something and I get this message: Summary: SELinux is preventing access to files with the default label, default_t.
Detailed Description: SELinux permission checks on files labeled default_t are being denied. These files/directories have the default label on them. This can indicate a labeling problem, especially if the files being referred to are not top level directories. Any files/directories under standard system directories, /usr, /var. /dev, /tmp, ..., should not be labeled with the default label. The default label is for files/directories which do not have a label on a parent directory. So if you create a new directory in / you might legitimately get this label.
I setup my chat accounts in this new social business, but after a reboot, even though the accounts are checked 'enabled, they did not sign on automatically. I can't fathom that this is expected behaviour. Is anyone else having this problem? Try logging out then logging in.
