I just tested this, and by copying some files from a previous install, I can indeed get this to work without green screen. So it seems our thinclients are out of date. greetings, J. <div class="moz-cite-prefix">Op 07-06-13 13:52, Jim Kinney schreef: </div> <blockquote cite="mid:CAEo=5Pyc60pRW4yq6HJsMYdxJUneMFa5Ru3zqJ=ys=W-G6KOmQ@mail.gmail.com" type="cite"> You'll need to rollback to an older kernel version for the TC or compile your own.

I will try to send you a screenshot of that. I checked the hardware of this hp thinclient: it has a Via Eden processor 1000Mhz, Googling the " unsupported processor centaurhauls" message I find this : <pre>nybody know the reason RedHat decided not to support the >>> VIA Eden Processor? </pre> If you take a look on google for "CentaurHauls i686" you will see that > this CPU/chipset SAYS it fully supports i686 but it really does not. > All of EL6 is i686 and not i586 (which CentaurHauls really fully supports). So this suggests that Centos has an issue with this thinclient There's also this site : <a moz-do-not-send="true" href="https://access.redhat.com/site/solutions/388693" target="_blank">https://access.redhat.com/site/solutions/388693</a> that I don't have full access to.

When booting this, i also see some EM, but K12Linux boots fine, and... <big>There's no green screen. It just works</big> So this fully suggests that the issue is the HP t545 thinclient. This is a showstopper for me, because this is our mainline thinclient. Thanks for any advise on this issue.

The reason NFS needs to be started manually is due to the RPM not knowing which interface you will be using for the LTSP network. This must be defined in /etc/ltsp/ltsp-server.conf before ltsp-server-tweaks and ltsp-server-initialize are run.

The fix for the 'stuck' Booting Linux line was I did not have nfs service started at boot on the server and had to manually enter the /opt/ltsp dir in nfs/exports. After this clients will boot fine.
