I'm attempting to setup VNC in way that emulates our other OpenSUSE installs - where you can connect to servername:1 and be presented with a graphical login screen. From there, you login and have a full desktop session.
I followed some steps from this site (very easy): [URL] ... and it worked like a charm. I get the graphical login screen, I can login, I can open terminal, some apps, move windows around, no problem. But, here's the problem: SOME windows refuse to appear.
For example, if I try to open "Add/Remove Software", it first prompts me for the root password, but then all I get is a "busy" mouse cursor and an entry on the task bar at the bottom that says "Starting Add/Remove Software" for about 5 seconds and then it dies off. The same thing happens for "Software Updater" and for almost EVERY entry under the SYSTEM>ADMINISTRATION menu. Which, basically means I can't change any settings via the GUI, which is kind-of the point! =)
I can't find any logging that helps me diagnose this, the windows just never appear. The behavior is the same whether I login as a user or root from the login screen (but, obviously, the root user doesn't prompt me for the password prior to running the apps). I've tried lots of different tweaks on the configs mentioned in the link above, but nothing makes any difference.
Edit: Version is CentOS 5.4 x86_64 I performed a yum update + reboot, no changes.

I seem to get logged into the NetApp filer fine - it shows the session, but I don't get a device. And don't panic - the system is CentOS 5.4, but the system is named OpenVMS (don't ask . . . ) iscsiadm shows me logged into the NetApp and the session is up.

I have a Dell 1435 with an AMD Opteron 64 bit chip, however when I install RHEL 5.5 I only get a 32 bit OS. The disk I'm using to install RH is the 64 bit copy, it says "For 64-bit AMD64 and INTEL 64" on the front of the disk. After the install I do a "uname -m" and it displays "i686" which indicates a 32 bit OS.1. Why does this happen?2. Is there a CL option that will allow me to force an install of the 64 bit os?I'm confused.I've installed literally over 100 systems and this never happened.

Currently our cluster is based on AMD opteron processors. We are going to add more nodes however I want to know is it good to add Intel xeon processors. They both claim to be x86 compatible however I don't know if they are really math each other.Does a program compiled on Intel xeon really works on opteron (amd64)?

I have an intermittent issue with with Samba. I can access my samba share with windows xp and vista using windows networking and even by mapping the share to a drive. The problem is that the files and folders disappear inadvertently and I can only access them again if I open the share again from the start with windows explorer. Selinux is disabled and the firewall ports for samba are open. The following software is installed:
samba 3.0.33-3.15.el5_4
samba-client 3.0.33-3.15.el5_4
samba-common 3.0.33-3.15.el5_4

Im trying to overclock my system and I cannot find a conclusive answer to this issue.It appears that I need to compile a custom kernel, is there a way around this?So where do I go from here without compiling a custom kernel and removing powernow-k8 from it?Is there a workaround to this? There is no setting in my bios either. ECS NFROCE3-A system board.

I have defoptions=quiet in my menu.list file and it keeps printing
ignoring bad line 1 'powernow-k8' across the screen during boot. The thing is that I have removed that line from /etc/modprobe.d/options, so why do I keep getting the warning?

If I boot my system with default BIOS settings (no overclocking), the CPU runs at 3.3GHz and powernow-k8 enables a maximum speed of 3.3GHz, as can be seen from the following:
[Code]....
Clearly, for some reason, powernow-k8 is mis-calculating the pstate 0 or maximum speed and this is reflected in the files within /sys/devices/system/cpu/cpu?/cpufreq/ I have tried to update /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq, however despite the file being writeable by root, the change is not maintained. Other than setting the CPU policy to "Performance" rather than "On Demand", is there any way I can force the correct pstate 0 (maximum) CPU speed?

I am testing version 11.2 (Released version) and have this problem (part of dmesg):
[Code]...
So Opensuse cannot lower the speed of the CPU-cores. I tried updating the BIOS without luck. powernow-K8 under Opensuse version 11.1 (dual-boot) works perfect.

In Lucid I cannot get CPU scaling to work anymore, in previous Ubuntu releases this was not a problem with the same hardware (AMD Phenom 9500 Quad). I used to load module 'powernow-k8' and 'powernowd' to make it work, but it seems 'powernow-k8' is not available in Lucid. Anyone who has cpu scaling working in Lucid?

I have installed a CentOS server with no GUI. I am trying to get RHGB work on startup. I did:
yum install rhgb
It installed rhgb and vte. I added 'rhgb' to the line in my /boot/grub/menu.lst :
Code:
default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-238.el5)
root (hd0,0)
kernel /boot/vmlinuz-2.6.18-238.el5 ro root=LABEL=/ quiet rhgb
initrd /boot/initrd-2.6.18-238.el5.img

We are currently troubleshooting the following error, which was repeatedly being displayed on the console:
kernel: Northbridge Error, node 2<0>K8 ECC error."
After replacing all of the memory, the error remained, so we tried updating to the latest kernel. (Currently having to use centos-plus because we are using XFS)
After the kernel update the error disappeared fro 5 days (previously UNHEARD of - would often repeat several times a day), it appeared again and hasn't appeared since.
It does not seem like any real damage is done here - and I would like to suppress this error somehow. Optimally I would like it to only be forwarded to the log files - and NOT be displayed on the console.
Could someone point me to an easy way to set that up?

I just install xen and kernel-xen version 2.6.18-194.26.1.el5xen, booting into the xen kernel dom0 shows me continous colorful scrambling and scrolling. I can ssh to dom0 and get correct display but the dom0 console is where it shows the colorful garbage scrolling. i have the Supermicro X7DC motherboard with a XGI Z9 graphics card. GUI is not installed and I don't have the rhgb parameter in my grub.conf. My grub.conf is plain and unmodified.

I used Ubuntu 10.04 64 bit and built a Ubuntu 10.04 32 bit VM using VMWare player.It's great, except it keeps reverting to a USA keyboard after each reboot.The host OS doesn't do this.The host was installed normally, but the guest was installed via the VMWare easy install thing which does everything for you.I've already set the location back to London, and I've added a UK keyboard to it, but still this odd reversion.I've googled and found other people reporting it but don't see any resolution.

No matter what I try, notifications do not appear. The notify-osd program is running (if I check ps) and nothing ever reports an error. I just don't see it, or hear it (does it make a sound?)
I think this might be because of my dual screen setup. I have two screens set up, with the screen on the right lower than the screen on the left so that they match up in real life.
This leaves a dead space above the right hand screen, perhaps its appearing in there? But I have already used notification-preferences to move it to the left (does that even work?) and still nothing. What's up? I rely on notifications to tell me that something's up, since the new "notification area" plugin does not flash and is thus utterly useless on this large screen display (design failure)
