I have to run a graphical session for using something with wine on a server (unfortunately :((( ) and I'd like to run a TWM session. As I would like to lock the session, I settled things to log on from XDM. However, I can't find anyway to lock the session. Is it possible (I guess yes) ? How can it be achieved?

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}

I was given 31 older machines. They are all identically spec'd at 900MHz P3, 1GB PC133 SDRAM, and 100GB HDD. I have decided to build a cluster with these machines and it was suggested to me on another forum to use CentOS. I have downloaded the ISO and burned it to a DVD. The beginning of the install works great until I get to the part when I begins to copy packages. It gets about 30% complete then hard locks up. The scroll lock and caps lock lights on the keyboard are blinking.
I have replaced the optical drive, tried a different hard drive, re-burned the ISO at slowest speed with a new DVD. Nothing seems to make a difference. In addition, I have tried to install ROCKS, and get the same thing. When it gets to the installation portion that looks like CentOS, it locks up with the same symptoms.
I've been having problems for a while with my pc at work and after a bout with a similar desktop I figured out that it somehow relates to the kernel updates from 5.3 to 5.4. I have two machines with identical motherboards (Asus M3a32-mvp), cpu ( athlon 64 X2 6400) and memory (8 gigs Corsair) with different video cards.
My desktop at work started with Centos 5.2 and was kept updated to 5.4 along the way. The other PC is my desktop at home and it started out at 5.3 and stayed there until recently mainly because my wife mostly uses it so I just never got around to doing updates.
Here is the problem, a while back the work PC started doing weird things, it would stutter, freeze up, sometime the mouse cursor would freeze into a cross hair and sometimes completely lock me out where even the keyboard wouldn't work so I had to kill power to reboot anf get control back. I eventually discovered that if I still had keyboard access I could jump to a console window, log in and killall nautilus or killall gnome-panel and I might get things back to normal for a while. I can even log in with another machine to use the killall commands if the keyboard locks up. I checked TOP during these episodes to see what was killing the system, I figured something was running a muck and gobbling up processing time or memory but nothing shows that appears to be off.
Like I said the home system was on 5.3 and not showing the stuttering problems so I even considered that the video card drivers might be causing something, that is until I tried to update the home system and got the same issues.
I had a hard drive failing at home so I figured I'd back up the data and reinstall the main system on a new one so I could start over with a clean system. This time I started from 5.4. Almost imediately I discovered the freezing problems after the complete install so after trying a few things I wiped and reloaded, couldn't mess around too long with it as the wife was really complaining about not having a PC, a 5.3 version. Bingo, now the system functions perfectly, no stuttering or freezing up. I then used yum updates to updates everything but the kernel. This also seemed to give me a system without freezes so I stopped there with the home machine.
Just to be clear the home pc used the standard yum repositories defaulted in the setup i didn't add any so it isn't a 3rd party repo causing the problems with the home machine. So it looks like the updates from 5.3 to 5.4 regarding the kernel seem to be causing me problems.
It's getting so bad at work I'm planning on wiping and reloading a 5.3 version and going from there but that's alot of work so I'd really like to just fix what is going on with the 5.4 version.
I'm working on a kickstart install to automate a lot of monotony doing installs. When i use the kickstart install i get an error on boot saying "File based locking initialization failed" "no volume groups found". Then it proceeds to boot up with no issues and appears to work just fine. Below is the section of my ks.cfg for creating the partitions: %include /tmp/partition.cfg is included where the partition info usually occurs. The user is prompted in the pre script for how large they would like the partitions to be and then the script below creates the included file with partition info

Session management with gnome-session-properties and GDM appears to be broken in CentOS 5.3 and 5.2. I can't comment on earlier versions.Activating "Automatically save changes to session" does work--for example, on the next login, the terminals that were open at the last logout are reopened.
But if "Automatically save changes to session" is not selected, according to help,"when you end your session the Logout Confirmation dialog displays a Save current setup option."This does not happen. No "Save current setup" is offered, regardless of whether or not "Ask on logout" is selected.
Also according to help, if one has added sessions with gnome-session-properties, then
when one logs in "on GDM, you choose a session. When you choose a session, you can
select which of the multiple sessions to use."This does not happen. No matter how many sessions one may have added with gnome-session-properties, none of them appears in the list of sessions that GDM presents.
So it appears that only a small fraction of session management functionality works in
CentOS 5.3 and 5.2.

When I do, vncviewer prompts for a password and then opens a window of the correct size, but it is all white and then my ssh session is locked! I can't enter any more commands, I have to kill the session.

I have been updating my system and making a few changes and now I have a serious problem with GNOME (as far a I understand). In the Desktop if I try to start some applications such as the text editor gedit it crashes and won't start. Some applictions start from the menu some don't (e.g. services) and others start and then crash if I try to example manipulate them (e.g. open a file in openoffice).
In the case of gedit if I try to run it from the command line as root I get the following

VirtualBox 4.0.2 from virtualbox repo.
nvidia driver 260.

I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.
