Normally Ctrl-Alt-L or clicking on "Lock Session" works, but as of the past couple of days when I do these, nothing happens. What could be wrong?
I also tried 'sudo kdesktop_lock' and 'sudo kdesktop_lock --forcelock' to no avail.

I've had two centos smtp relays setup since 5.1, and it seems every day there are updates, and about every 3 months new minor releases.Is there a way to "lock" to a minor release version of centos? I use yum update to run updates, is that the correct process?
View 2 Replies View RelatedI work for a local community college, and we currently have web kiosks set up around the college. They have fairly old hardware and are currently running windows XP. However, with all the group policies and scripts required to lock them down, it can take 10+ minutes for the students to log in(we want authentication for someone to be able to use them).
Now, I have managed to get a few test computers to run fedora with openLDAP authentication and LTSP giving them a desktop with firefox. Now, the problem is that we don't want the user to be able to do anything but run firefox and, on some of them, print. I have been using gnome, gconf, and sabayon(not the distribution, the user profile tool) to attempt to lock down the desktop. However, anyone can just right click the gnome menu and add back in everything i disabled. While they wouldn't be able to do much harm, the point is that if they want to do work, we want them to go to our computer labs, instead of the kiosks. The kiosks are just for looking things up or getting on their e-mail.

View 0 Replies View RelatedI'm running opensuse 11.2 on my Asus 1000H, today I found the new kernel Kernek-Desktop 2.6.31.8 will cause system lock down when I try to connect to any wifi assess point. I updated to 2.6.31.8 from Opensuse-11.2-update days ago and today it's my 1st time to try to connect to wifi with this new kernel.
Downgrade to 2.6.31.5 will solve this problem.
I had a system lock up recently, running RHEL4, and had no choice other than to powercycle as I could not log on at the console or remotely.
When booted, the machine ran, I could log on remotely and apache started up, but the system locked up again when I logged on to the console with X.
I suspect that the X configuration and/or the NVIDIA monitor driver was messing things up and I took the opportunity to migrate to CentOS 5.3.
How can I determine what happened? I still have the /var/log files when the system locked up including messages, boot.log, Xorg.0.log, etc.
I _SUSPECT_ that what messed up X and thus the system was the NVIDIA driver that I downloaded to get X to work on the console monitor, a SUN AI24PO. X would not work with this monitor and any of the default drivers that came with my RHEL4 disks.
I really hesitate to use connect this same SUN AI24PO monitor again but still, I only have a suspicion that the monitor/NVIDIA driver were the reason the system locked up.
The graphics card is a GeFORCE FX5200
Were the lockup problems a result of the monitor/NVIDIA driver?
I've googled for the answer to this but every thread has the same answer "don't log in as root". For once I'd like an actual answer to the question if possible. All of the jobs that I run are all through the root account and I'm constantly using ssh into other workstations and servers to change config files or whatnot. I'd like to be able to lock the screen when I take short breaks or head out for the day while being able to leave jobs running. For example I am currently backing up a server onto another one and would prefer not having to stop the jobs when I leave for the day(there's over 400GB to move).

View 3 Replies View RelatedIs it just me, or has 'lock screen' stopped working in a recent update? I updated my install today and after rebooting I can't lock the screen... the screen saver doesn't lock it and if I select 'lock screen' manually from the menu then... nothing happens.
I even created a new user in case there was something weird in my configuration, but logged in as them I can't lock the screen either.
This is obviously a bit of an issue in an office environment as I don't want to have to log out every time I leave my desk.
I want to lock the filesystem based on user basics, In effect only specific users should have write access. This need to done apart from normal permission setup.
In Detail:
filesystem: /app
application users: appuser1 & appuser2
Normal users: user1 user1
Required: Only app users need to have write permission over app file system, this should done apart from the normal directory permissions. The all other users can able to view the contents even though other users have write permission based on permissions.
This need to done by over ridding the normal permission setup.

I have a HP Pavilion dv4 that is 4 months old. Yesterday it suddenly seemed to restart then once I logged in it turned off. When I tried to turn it on some of the lights came on and the caps lock and num lock started flashing. Since then I have not been able to get it to work correctly.It once seemed to turn on but died again after the login window.I tried to use my live cd but the same thing happened. It started loading once, but then shut down again. Every other time it stayed dead minus the lights
View 1 Replies View RelatedI recently installed Ubuntu 11.04 on an old Sony Vaio laptop. I was following some of the steps here..[url]
The step "Enable Full DVD Playback(Dual Layer DVD Support)" did not finish correctly doh and now I can't use 'sudo apt-get' for anything or the software center or using the 'Update Manager' does not work.
The update manger says it may be caused by an update not finishing correctly which sounds correct as explained above. The apt-get command gives me back the following....'Could not get lock /var/lib/dpkg/lock resource temporarily unavailable' 'unable to lock administration directory /var/lib/dpkg is another process using it?'
I tried the obvious restart but that hasn't worked.
For the sake of security, I want the screen to be locked after the system is resumed from suspend or hibernation. Now the only way I can do this is to check the options "Lock screen when screen saver is active." in the screensaver preference. But this method is annoying since I have to type the password to quit the screensaver. Is there other way to do this? Thanks.
By the way, I use CentOS 5.2 x86_64.

View 1 Replies View RelatedThere is a very strange problem I've been having. When I enable either Caps Lock or Num Lock the media controls on my keyboard cease to work. I have Googled this one to death but found nothing. This problem existed in Xubuntu 9.10 and now still exists in Xubuntu 10.04. The keyboard I use is a Logitech Elite Keyboard. I would love to be able to use the Caps Lock and Num Lock without the worry that I am disabling the media controls

View 6 Replies View RelatedI'm wondering why the num lock doesn't work in Ubuntu anymore? When you press the "num lock" key, you're supposed to be able to input the numbers along with + - * / and decimal point. When I press num lock and try typing numbers, nothing happens.
I've done a google search and this is a well known problem that nobody has fixed. In Windows it's never a problem.
Seems such a shame that the great Ubuntu and Linux are so good for stability and speed, but can't get a simple num lock working.

I'm trying to install CentOS 5.3 on a VMWare virtual machine running VMWareServe 1.0.4 build-56528. I have 8 virtual machines that are running some older kernel (RH FedoraCore 4) without any trouble. My system has an AMD Athlon XP 1800 processor and has 1G RAM. Every time during the installation after choosing skip media (I have already checked that the media is OK) I get a kernel OOPS and the capslock and scroll lock keys start blinking. My first guess was that this could be a ACPI issue, so I have disabled ACPI using the acpi=no boot option. The problem persists with the acpi=no option set. During the boot install process, I have seen some messages like this one
ACPI Exception (processor_core-xxxx): AE_NOT_FOUND, Processor Device is not present [xxxxxxxxx]
I have searched for this issue and found a RedHat Bug 435653 that reports this same issue, but this report is somewhat old, so i think that this issue as already been fixed and reflected to upstream. I have tried also to install using the text mode installation, but the same problem. To further isolate this problem, i have avoided the hardware detection and this was the first time that i have overcome the first screen (test media screen), as i have choosen with the success the language and the keybord layout. After choosing the beyboard layout, the kernel OOPS shows up again. On the screen 4 (debug screen) I don't see any relevant messages.
I've faced the problem with server freeze on heavy write.

View 6 Replies View Relatedi find this is an issue which might be tiresome for everyone except for those experts. Esp. for the computers which are dual booting(both windows xp and centos installed in the same computer), that when we are in CentOS we need to switch onto windows immediately. and vice versa. i see this is possible only by shutting down the centos/windows and then restarting onto the other OS.
Can anyone tell me the the solution to work simultaneously both xp and centos without the need of shutting down and restarting There maybe or may not be the solution...but i find the pleasure to know if there is for example, remote desktop connection in windows xp, is there any solution, we can work on windows via centos or vice versa ( in the same machine),
I am trying to install CentOS 5.2 on an HP rp5700 desktop unit. These units were originally sold as a Point of Sales unit I believe, but HP also markets it as a high life cycle server for SMB market.I tried to load CentOS on this unit via CD (created from downloaded ISO of course). It presents the initial CentOS banner page and waits for the obligatory "enter" to continue. It begins the boot process up to discovering the PCI stuff and just locks up, no response. I have to power down to restart.Since this does not even get to the point of installing. I am at a loss what to do next. Has anyone had a similar issue with other PCs.The boot stops at the lineACPI: PCI Root Bridge [PCI0] (0000:00)
