If so there is a problem with the current driver. (As a side note this problem has also been reported with windows so it known problem on intels side). See my bug report here. https://bugzilla.redhat.com/show_bug.cgi?id=511867 Questions: 1. Do you see the plymouth boot screen? if yes then it is using the intel driver. I would recommend using F10 version. The driver works but has problems with compiz. And you have to adjust grub if you want to see the plymouth boot screen (vga=792 nomodeset) If no, then it is prob using vesa like you said but I think not. Try recreating the X11 config file and force it that way. Steps: 1. Install system-config-display su yum install system-config-display 2. Run system-config-display and save your changes. This will create X11.conf file and will use this config when boot your server. 3. Also try using 'nomodeset' in grub (tell me if you need help on how to do that.

Are there any major gotchas etc? Reporting the outcome and following up on my own post. First, thanks to Warren T. and Paul S. for the links - helped me get a better sense of what was involved and lead to putting /boot on a separate partition. The devil was indeed in the details and after running into problems I changed direction in favor of a totally fresh install. Following my upgrade/cloning plan, the system wouldn't boot at first because of LVM configuration information copied over from the old /etc directory. After that was sorted out, it booted but with a bunch of exportfs errors. Since the clients depend heavily on the exported filesystems a fresh install was the logical/least troublesome option and I did a software raid install with home on a separate partition as planned. After transferring the old /home partition contents to the new /home raid partitions and replacing the /etc/group,gshadow,passwd,shadow files everything is working fine.

As we've discussed on here and on the ltsp list in the past, when viewing sites that have lots of images, earlier versions of firefox sometimes would crash the xserver on the client as a result of using up all the client memory with cached images. This doesn't happen with FF3 - it has clearly been rewritten and all images are loaded on the server and transferred across the network without been written into client memory. The downside is that on the same (very) graphic-heavy sites where Firefox 2 would sometimes crash (but was otherwise perfectly acceptable in terms of performance) Firefox 3 scrolls slowly and is quite jittery redrawing the screen with significant errors, overruns, and dropped packets on the network. Firefox 3.5 is reported to be much faster rendering pages but that may not make up for the performance drop on the clients. For now I'm using Opera 9.64 for anything other than sites that are mainly text. My system: LTSP 4.2, Term 150e w 128M ram, GigE to clients/100Mb network, trident xserver and Firefox 3.0.12, X86_64 builds of FF and Opera. How is FF3 working for those of you running local apps, ltsp 5 etc?

We've already tried those suggestions of "nomodeset" and other various settings in our hunting, in F10, the driver was working, and Plymouth would also work, and it seemed like Compiz was functioning to a degree at least. However, any 3d-application would be unaccelerated, using only software rendering. A dump of glxinfo shows that it is using the software renderer vs. the intel accelerated flavor, but yet a live distro CD will run fine, with the proper acceleration. I suspect we must be missing something in the boot image or configuration that is causing this to occur, but am unsure of what to try next.

And if you can tolerate reading a non-commercial commercial, continue reading. Otherwise, stop! --Tom As a new school year approaches in much of the world, I'd like to take a moment to point out that while we generally promote SchoolTool as a free, open source student information system for schools, it can also be much *less* than that, depending on your needs. That is, since SchoolTool is free and easy to install, particularly using modern virtual servers, you can use SchoolTool to solve specific problems without facing the much larger issue of migrating your whole school to a new information system. Collect Assessment Data Science Leadership Academy in Philadelphia uses SchoolTool to create and print regular interim reports on all students. SchoolTool's new Report Sheet feature facilitates collection of grades, test scores, comments or other custom data from teachers at regular intervals. Stop emailing spreadsheets! Track Grades and Attendance Jeff Elkner of the Arlington Career Center in Arlington, Virginia, uses SchoolTool as his personal gradebook. Anyone using Ubuntu Linux on their desktop or laptop (or server in the "cloud") can easily install and use SchoolTool as their online gradebook and attendance journal. Schools can offer SchoolTool as a free alternative to teachers wishing to move their bookkeeping online. Schedule Resources Online The Paul Cuffee School in Providence, RI uses SchoolTool to coordinate the use of their computer labs and laptop carts. Teachers can check what resources are available via SchoolTool's calendar and place reservations online. SchoolTool is at a point where a small community of individual users and schools implementing some of the above features will do a great deal to keep the project moving forward, and we have developer resources to assist and respond to bug and feature requests, so please have a look and let us know what you think.

That's separate from which LTSP server you're querying for your XDM logins. What I'd try first is tweaking your lts.conf file to point "SERVER = " to your K12LTSP 5.0EL server, but leave everything in your DHCP scope as is. That's perfectly legal to do, and I've done it. What will happen is that your DHCP scope will still tell your clients to point to your K12Linux (FC11) server for the stuff in /tftpboot and /opt/ltsp/i386. That's where the X11 stuff, including all your drivers, lives. But that's just to get the mini-Linux OS and X11 running on the thin client, nothing more. From that point forward, i. e. once the client has X11 up and running, it can do the XDMCP query to *any* XDMCP-speaking X11 server. Usually, and by default with LTSP, this is the same box as the LTSP server from which you're booting your clients. But it doesn't have to be. --TP _______________________________ Do you GNU ?

When booting the K12Linux live CD, the kernel module is loaded (aic94xx) but it complains about missing firmware. After doing extensive research on the issue, I found the firmware and put it in the proper location and reloaded the kernel module. The controller and drivers were found! However, after installation, the initrd does not contain the firmware needed to initialize the controller/drives. I've read many reports about this firmware being manually added to the initrd but it is still not found or doesn't work. So, the question.... has anyone gotten this to work? The problem is specific to Fedora Core 10 and possibly a few releases earlier and is rearing it's ugly head on this K12Linux install. It seems a rather innocuous problem but I just haven't found a solution yet. Thoughts? Tim Nelson Systems/Network Support Rockbochs Inc.

You could also try adding: DESKTOP=KDE to /etc/sysconfig/desktop on the server, though that would change the default for everyone. Not a bad thing IMO.

Daniel > There's nothing wrong with managed switches, generally. I've run LTSP on quite a few brands over the years, and I love 'em. One key factor is spanning-tree negotiation. Normally the spanning-tree algorithm will take about 30 seconds to bring up a port. It's usually necessary to turn on what is generically called "Rapid Spanning Tree". Some vendors call it "fast-learning" or "portfast" or something similar. Apple Macintoshes, including those running OS X, also required this back when we still had some of those. Now, all that said, I doubt very seriously that this is a switch issue. The reason is that you told us you can get 50 clients running just fine. Ethernet switches actually don't give a rip if your traffic's even TCP/IP. They only care that your frames have the proper 802.3 Ethernet header, and however many frames there are doesn't matter, up to the capacity of the switch's backplane. The fact that you had K12LTSP 5EL working just fine on it before tells me it ain't the switch. --TP _______________________________ Do you GNU ?

Daniel 'Negotiation Error:' is one of the possible messages from the nbd client so I think you are on the right track. Are any there any messages logged server-side to show if you've run out of resources (maybe in /var/log/messages)? Does a 'df' show a partition out of space when you get to this point?

If the TC's do, in fact boot OK with the unmanaged switch then you'll have to start digging into the setup of your managed switch. At least this would resolve or not resolve one possibility in your equation.

Here's my understanding of each: 1. Thin Clients: All processing, memory, and storage comes from the server. The desktop is essentially a terminal. 2. Diskless Workstations: The desktop uses it's own CPU and RAM for running applications, but relies on the server for its hard disk. I have modern desktops that I would like to use as diskless workstations, but am not sure if this is supported by K12Linux.

This should do okay but really is at the bottom end of even where consumer desktops are in computing power. If the whole class decides to visit a flash-based site at the same time, there may be some grumbling. Quad cores aren't that much more. If you were buying just a bare CPU, you could get a quad-core AMD for $110. The chip in this server is a clear out model, the successor only costs $60. Also, see what the cache sizes are on the drives. Again, the spread in price between a 250 gb with 2mb and speedy 500 - 750 can be as little as $20-30. Glad to hear things are going well.

A beefy thin client that runs some of its applications locally would be what you describe as a diskless workstation. It's possible to have a thin client that runs pretty much everything on the server, a few apps locally, or something that downloads the OS and runs everything itself only using the server for disk, as you said. k12linux tends more toward the all-on-the-server end and DRBL (Diskless Remote Boot Linux) tends more toward the nothing-on-the-server-but-the-disk end, but it's possible to create something somewhere in between.

I priced the quad core from Dell and it doubled the cost, this was a special with $300 off the normal price, guess we know why now...good news is it's for an English class at Sutton, with the old laptops as thin clients and the APS classroom thin clients...even a good server wouldn't help those clients much with video I think. But the next server I buy is probably for the lab, so I'll keep all of your comments in mind! Best, Daniel
