View 2 Replies View RelatedI installed openSUSE 11.4 on HP elitebook 2560p few days ago (using KDE live CD). In general system is working fine, but steel I cannot resolve couple of really annoying issues: 1. I've created encrypted partitions for swap and home during OS installation. As result the system keep asking for passwords for each of encrypted partitions before show login screen. That leads to situation when I have to type 3 passwords during each boot/reboot. I was using the same configuration (swap and home were encrypted) on Ubuntu 11.04 and there both encrypted partitions were mount automatically with no password typing after login to the system. Could you please tell how I can configure the same behavior on openSUSE 11.4 ?
2. I've enabled auto screen lock after 5 mins being inactive. As result when I going back to laptop and to unlock the screen the system shows login screen (default login screen with user selection). But when user and password filled in I click login it creates entire new KDE session. Therefore all staff that was open before screen lock is gone. However old session is still in the system (it appears in output from 'w' command).
Posted this in the wrong section so I'm reposting it, is that ok? I installed lxde and logged out and switched to it, but my internet wasn't working (but that's a different thread after I fix this, I was going to try installing wicd) So I tried to go back to gnome, I misclicked and accidentally started a different session. I think it said openbox/gnome, all I get is a blank screen with just the desktop background. It's set to automatically log me in, so when I restart my computer it goes back to the blank screen. How do I get back to the login screen?

I can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. After that, I can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. I have reinstalled X and KDE twice now as well as deleting my .kde folder. This condition started when I inadvertently ran out of disk space on my /home drive. Since then I have migrated /home to a larger drive and watch it's disk space very carefully.

When i log in as root, and try to click the lock screen button, lock screen doesnt work? Is it disabled by default?is there anyway to lock screen when logged in as root
View 6 Replies View RelatedI'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 1 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.
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.

I am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.
View 3 Replies View RelatedI have installed CentOS 5.2 on a couple of machines. They work fine, but the screen goes black (blank) after several minutes. It's a screensaver of some sort. I'd like to disable it. I searched the CentOS forums, searched Google, searched Yahoo, and I can't find any way to disable this blank screensaver.

View 3 Replies View RelatedI've been trying out linux distros to see which I want to progress further with. I have a bunch of removable HDDs. I put a single distro on each HDD. I just installed CentOS 5.4 on a machine that has had successful installations of Debian 5.0.3, Fedora 12, and OpenSuse 11.2 installed on it. I still have those HDDs and they still boot and run fine.
CentOS 5.4 installed in graphical mode just fine. I even noticed that it appeared to probe my video card (ATI Radeon 9250 AGP) just fine. I removed the media and rebooted and the CentOS graphics came up fine, and it asked me a few questions such as could I hear the sound. Everything went fine when it said it was now booting to CentOS for the first time, and the screen went blank. The monitor LED stayed green, however, so it looks to me like the monitor still sees a signal.
I'm guessing I need to boot into text mode and fiddle with the display settings, but I'm pretty much lost there.
I did a lspci under Fedora and it lists the following for video:
let me log out of my dang XP machine, and cut and paste the entire stuff straight from the machine I installed CentOS on which is now running Fedora 12.
I just installed Linux 5.5 on a Toshiba laptopn (i3, 64 bit). Centos runs until it reaches a very dark screen. On a few occasions, I am able to see something but the screen is very dark.

Alt-f1 switched to a different virtual console, which was just a blank screen and a blinking cursor, but now able to type things. Want to avoid hard shutdown. Is there anyway to force shutdown/reboot the machine from this console?
View 1 Replies View RelatedI've been trying to install 5.5 here for the past few days, first from USB and now from the CDs, with no success. The problem occurs when I reboot after installing. After the BIOS has done it's thing I'm faced with a blank screen with a blinking cursor at the top left of the screen.
Initially I assumed that this was due to the intel driver problem which is reported in the release notes as a known issue, and the PC I'm installing on has intel graphics. However I have now done a text install and still have the same issue. I'm able to boot up the system using the CentOS live CD, which encounters no issues, and it mounts the local system no problem. After unmounting and remounting to get write access I'm able to change the device entry in /etc/X11/xorg.conf to have the Option "DDC" "false" entry. I can also see that the runlevel is set to 3 in /etc/inittab, still I get the blank screen on attempting to boot.
Any ideas on what might be wrong here? It really sounds like the intel driver problem people have described, and yet I can't even boot in text mode so that doesn't seem to be the case here. Could there be something wrong with the bootloader?
So I have a laptop that I built and installed 10.10 on.
The laptop is used by a minor who needs to be off it at a certain time but can't seem to keep track of time.
I have installed that Nanny program called "Parental Control" through the software center but its not quite what I want. It says it locks out the session...but it seems pretty much useless.
So what I'm looking for is software that would not just lock the session and require them to lock the computer but to literally lock the laptop so they won't be able to use it at all until the time lapses or the admin password is entered.
I crearted one user on my linux machine when i try to lock the session it works for the first time.
The next time if i lock the session it doesn't work.
I tried several times but same problem.
I am using KDE 3.3
First time I am having issues with Centos.
I bought a Intel DQ45CB LGA Q45 Micro ATX Motherboard and I am installing the 64 bit version of centos.
The install of Centos goes just fine. However when I first try to boot up, after post is done, I get a blank screen. I do not even get on the Grub screen. No access to any of the ttys. No access to anything, files, folders. I only get a blkinking cursor, no command prompt, nothing.
This happened with Centos 5.2 and 5.3
Just for the hell of it, I installed XEN Xitrix and I have no issues like that.
I installed CentOS 5.5 last night using the DVD ISO (from a USB drive thanks to the Universal USB Installer). I selected the Server and Virtualization packages, and finished the install all the way through. At the end, the installer asked me to remove any installation media and reboot the system. After rebooting, the system hangs on a blank screen with a blinking cursor in the top left corner that does not accept text. This is before the GRUB screen appears. For partitioning, I created a 4GB swap partition on sdb and a 16GB ext3 partition on sda, mounted at /, with the remaining free space on sdb mounted at /storage.
Does anyone know why this system is hanging before the GRUB menu?
I have experienced that the button in my main menu "Lock Screen" does nothing, so I can not lock my screen. What could be the problem? Is there any command in terminal what I could write, so I can see is there an error output or something?
I am using Ubuntu 9.10, GNOME.
I noticed (the hard way) that enabling a guest session under 9.04 does not lock the source user. I enabled a guest session for someone and came back to find them rooting through my files. By quitting the guest session, it goes back to the source user's desktop without requiring a password. Shouldnt it go to gnome-screensaver automatically? Can this be changed? Is it a bug?
to replicate: log into source user's account use the menu to start a guest session quit the guest session root through files un-opposed.
I am putting together some new systems for my customer and I'm having some trouble with a script that we use to back up files to a DVD R. The problem is that I can't write a 2nd session to the DVD unless I eject the disk and reload it. The drives are slimline type drives, Sony BD-5730S and Teac DV-W28S-V93, so they won't reload without human intervention. Opsys is CentOS 5.4 or RHEL 5.4. I've tried both AMD and Intel based mother boards. If i try this on Fedora 11 or 12 it works fine. This works on IDE attached drives but not a SATA attached drives. Fedora appears to use something called genisoimage instead of mkisofs. I can't get genisoimage to run on CentOS or RHEL.
Here's the code to setup the test files:
rm -f /tmp/BDtest/*
mkdir /tmp/BDtest
dd if=/dev/zero of=/tmp/BDtest/blank.iso bs=10M count=1
for NUM in {1..160}

When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.
