CentOS 5 Hardware :: 5.3 - 4Gb RAM Added - Boot Fails - Can't See Login Screen
Jul 9, 2009
I have a Dell precision 380 (system specs can be found here: [URL]. My system is set-up in dual boot configuration with Windows Xp x64 on one side of my HD and CentOS 5.3 (64bit) on the other. My system came with 2Gb (2 x 1Gb) of RAM and I recently wanted to upgrade. I bought 2 x 2Gb ELIXER DDR2 667Mhz RAM. I carefully added the new sticks to my motherboard, booted up windows via bios which noticed the new RAM was present. All seemed well.
However, on rebooting the system and entering the CentOS boot phase, after the boot phase (eg starting program... [ok] etc) but before the login screen my screen goes black / blank. My system has an ATI FireGL v3100 graphics card, I checked out the technical info on this and it should be ok on 64 bit linux. (See: [URL])
[Code]....

I have a issue that could get me fired, so I would appreciate your input. My knowledge about linux is limited
The company I work for has a Dell Poweredge 6850 that keeps pretty much everything (databases, websites, etc). The server had a Virtual Drive created from 2 Physical Drives. Since the HDD space was getting low, we got a new drive, inserted it, formatted and rebooted the system. But the system now refuses to start, giving an FAILED message, something related to EXT2 partition that cannot be read at /dev/hda1

I've got an install of CentOS 5.3 in a VM which was installed without X or Gnome.I've added X (yum groupinstall 'X Window System') and Gnome (yum groupinstall 'GNOME Desktop Environment) and can now run startx no problem.However on boot I get a command line login rather than the graphical login screen one normally gets if Gnome is included at install time.What do I need to do to get the graphical login after boot?

I've been running xubuntu for a few weeks now, but just today I began having a few problems. When I boot my computer, it simply freezes at the xubuntu logo just before the login screen.
The last thing I remember doing before this is typing export DISPLAY=:0.0 in the tty1 terminal.

I use Ubuntu 10.04 LTS.
I was compiling an application called Audacious. One of the dependent packages I needed to obtain was called Glib. After installing Glib (and a package it also required), my GNOME began failing and after rebooting the computer, the login GNOME login screen fails to displaying. Does anyone know what's gone wrong?

Now after installing Glib, restart your computer and your GNOME will have failed. Why the F did this happen?

Today I upgraded my system to the Nvidia driver 340.93 and 4.2.0-1 kernel on Debian Stretch.
While I wait for the gnome login screen to pop up I get the "Oh no something has gone wrong" message.
When I log in from another terminal and execute startx , gnome initiates and starts although settings like my resolution and other xserver settings are not loaded.
From the journalctl I believe the error is located in the following section:
Code: Select allOct 06 14:23:17 DEBIAN-PC org.a11y.atspi.Registry[1692]: SpiRegistry daemon is running with well-known name - org.a11y.atspi.Registry
Oct 06 14:23:17 DEBIAN-PC gnome-session[1680]: X Error of failed request: BadValue (integer parameter out of range for operation)
Oct 06 14:23:17 DEBIAN-PC gnome-session[1680]: Major opcode of failed request: 154 (GLX)
[Code] ....
I reinstalled the xorg-xserver and the nvidia drivers and I get the same behavior.
Looking for some info in order to reconfigure the gnome-session to work?

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

i am having a boot problem with opensuse.i installed a theme named suse-elegant under personal settings(configure desktop)-system administration-login screen.
i had also added vbox users(i ticked vboxusers) under yast-security and users-user and group management-edit-details to make virtual box work.
i want to check that installed theme so i restarted my laptop.after the restart opensuse taking too long time to boot
note:the login theme also not working.
after the boot i restored defaults in login screen themes.it is also not working.
i don't know which cause this problem(vboxusers or login theme).i am also seeing a root user has been added in my login area.i tried opensuse failsafe also.

I am using Ubuntu 10.04.1 and I run it 24 hours a day. Recently one morning I went to my laptop and opened the screen but the login screen wouldn't appear. Anytime the cursor appeared, HDD activity would go to 100%. I'm assuming this because the HDD light on my laptop was permanently on. So I made the dumb decision of just holding the power button down and turning it off. When I turned it back on, I noticed it came to a command prompt type screen listing "initramfs" at the bottom apparently wanting me to input a command. I did a lot of research and couldn't find much of anything that would help me. I read about GRUB, superblocks, fsck, e2fsck, etc.. . I tried all of those and nothing has worked so far. Any ideas? I did notice one thing. When I went into the actual install with the livecd, it told me the drive was /dev/sda5, but in Disk Utility on the livecd, it told me it was /dev/sda1

I'm trying to make dual boot system with Lenny (64bit) along with WinXP. I'm using one HDD with 2 partitions and installed first XP then Lenny. Everything seems fine till the first boot after fresh install. Lenny starts to boot and after same point the screen goes blank and then is turned off and that's it...nothing happens. Happens so fast that I'm unable to see the exact messages on the screen. Maybe somewhere around staring anarcon?
PC is:
Athlon64 X2 5400+
Asus M2V-MX motherboard
3GB DDR2 800
500GB WD SATA2 HDD
Radeon x800 GTO video
I reinstalled 2 times and it's the same. WinXP is working fine though but I really don't want it to be my OS...
Another "hint" from today: The same happens when I use "Try without installing" of Ubuntu 10.04(i386) Live CD. It starts loading and at some point turns off the monitor.
Tried also with 8.04(64bit): Boots till it reach something like "Settings sensor limits" and then it's stuck. I have consoles though (Ctrl+Alt+F1/2/3...).

I'm using CentOS 2.6.8. It was working fine until yesterday. I tried to install openvpn into the system. I heard I need to download [URl} first and run it. But I got failed on doing sudo yum install openvpn I'm not familiar with the system, so I just give up the installation.
However, today, when I boot up the system, I can't run into the login screen at all! It force me get into kernel and I got
[root]#/user/bin/rhgb-client: error while loading shared libraries: libglib-2.0.so.0: cannot open shared object file: No such file or directory
when I try to use "ls" command, I got ls: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
I think I ruined everything yesterday and totally panic now.

I just recently put Ubuntu 10.10 for ppc on a Cd-R and installed it onto an old Mac I had found. The installation seemed perfectly fine I booted the computer and was presented to boot with two options "Linux" and "old" or to press enter and boot default. I had decided to boot default and it reaches the splash screen where the loading bar advances two dots and then completely stops.

I have just finished updating my older box from 8.10 to 9.04 and installing a bunch of programs. I had shut it down several times between sessions but when I unplugged it and moved it, it fails. It goes fine through the BIOS and GRUB (I think) but then when there is a screen of text it flashes to black several times and then displays a screen that looks like static with "Ubuntu" barely visible in several places.

I have installed ddclient for use with dyndns.org.
I can manually run it from the prompt with /etc/rc.d/init.d/ddclient start
and can verify that it works by checking that my IP has succesfully been changed at dyndns.
When I reboot though, during the startup, I get the following:
Starting ddclient: /bin/bash: ddclient: command not found [FAILED]
I am very new to Linux, so I am not sure what or where I should be looking to solve the problem. It seems to me that it must be looking in the wrong spot for ddclient, but I don't know what to check or change to point it at the right place.

Does anyone know a way to activate a screensaver at the login screen? I've got about 5 machines here, and I'd really like the ability to just have the screensaver come on after 5 minutes of sitting there with nobody logged in...
Even a way to blank the screen would be nice. However, if we were to blank the screen, I need to ensure that it doesn't do a DPMS blanking, since we use calibrated monitors here, and turning them off sucks.

I just installed Centos 5.2 with a netinstall usb key. I had no Belgium keyboard mapping available during installation, so I chose a fr-latin1 layout. Now this is the default keyboard mapping for the gnome login screen, and for every new user on the system. How can I change this to a Belgium keyboard layout? I can change it for myself within my gnome session in Preferences>Keyboard, but I haven't found how to change the "global" or default setting.

We like the centos colour scheme but would like to add our own logo to the login screens and boot process of gnome. I have attached the two screens we would like to adjust in the install package. Where they are located and what the process of editing them will be?

Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.

When I login to my machine I can see a BLACK screen and my mouse pointer. This is not happening with other users.Few days ago when I tried login to my machine I noticed this. I can access ssh session and do stuff there but some time I need GUI.I can login fine using other users. This is only happening with one specific user.I have just noticed that if I try loggin with the same user which have issues using NX client it shows us a BLACK screen, then if I open xwin then I can see three new windows top panel, bottom panel and Desktop.

My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.

I had a perfectly well running CentOS 5 system but with an old crappy monitor. I replaced the monitor by a bigger one, i did a monitor detect to make sure that CentOS would recognize the highest possible resolution. Then changed the display rsolution for the current user.
Now when i login as root just a black screen appears with a white mouse pointer and then nothing. I already deleted all the contents in the home directory /root but no improvement.
When i login as a new user X is starting perfectly.
Anyone have a clue what i need to do or delete to get X working again? I can nuke the whole box and do a reinstall but i'd rather not.

I am setting up a CentOS server that has no screen connected, and only has 2 Tesla cards. I have created a minimal xorg.conf and xinitrc file that doesn't load mouse or keyboard, and only creates two screens, one for each card at 320x200x24 bit. This is so I don't waste VRAM on a framebuffer I can't see.
I modified the xinitrc to just load tdm and nothing else as GNOME is a RAM hog. I am then using this setup to render stuff offscreen using OpenGL into FBOs which I read back to CPU and process. Currently for development I just run startx& when I login. I now want to know how to set x server to start automatically at boot. The CentOS docs say that it will try to load the GNOME login manager. The thing is that I don't want a login manager as it is useless as I login remotely via SSH.So:
1 - how to enable automatic x server in CentOS (im used to Ubuntu so not sure how to do this on Red Hat variants)
2 - leave x server running without starting login manager
