[CentOS] Centos7/Kde4 freeze
Hi I have a fresh install of centos 7.4 with KDE on a laptop (latitude 5590) connected to a DELL WD15 dockstation with an additionnal screen. It works quite well, I have 2 screens side by side (default config), but If I add a second menu bar for the screen connected to the dockstation (KDE allow for this) it is not possible anymore to start a kde session if the laptop is not connected to the dock station (eg: at home), kde freeze and never show any menubar. I have to use gnome to login and remove the .kde directory. Is there a way to avoid this ?

Re: [CentOS] CentOS7: Setting up ldap over TLS in kickstart file
Thanks Paul and Gordon for your reply. I'm not sure, but I think the problem is setting up ldap+TLS while the certificates are not uploaded on the server. So I decide to setup LDAP in a "post" section only, adding the "--enablesssd --enablesssdauth" options suggested by Gordon too. in the kickstart file: *auth --useshadow --passalgo=sha512 * in a post section: # LDAP setup *authconfig --enableldap --enableldapauth --enablesssd --enablesssdauth --ldapserver="ldaps://my.ldap.server" --ldapbasedn=dc=my,dc=local,dc=dn --update** *# Certificat Upload *cd /etc/openldap/cacerts/ && wget http://xxx.xxx.xxx.xxx/Softwares7/LDAPCERTS/ca-bundle.crt** *# server public key upload *cd /etc/openldap/cacerts/ && wget http://xxx.xxx.xxx.xxx/Softwares7/LDAPCERTS/server.crt** *cd / # TLS setup *authconfig --enableldaptls --update** * And this works fine. Certificat bundle seams to be accepted (I've also tryed to split the file, no change) and the last command builds the hashes of the certificates too. My last problem is that firstboot --disabled don't seams to work in my config but... Thanks for your helpfull suggestions about sssd and certificates.

Even not knowing python, it's fairly obvious - it says you need Python
version 3.4 or greater for numpy 1.12.0, you've installed Python 3.3
Generally, I don't use pip for installing numpy - it's such a common
requirement for other packages that it's in the repositories. Try
something like
yum install python33-numpy
P.
Using "yum install python33-numpy " could be a solution for numpy but this just
forward the problem to the next package I have to install with pip. I do not
understand why a python 3.3 environment try to install incompatibles packages.
I tryed to install python34 with yum but it does not seem to work with scl
environment (yum install python34-setuptools python34)

This is why the wiki instructions tell you to create your customized config file and show you how to get that config file to be used during the build process. I have another suggestion for you. Get the srpm for the CentOSPlus kernel instead of the distro kernel. The plus kernel is a customized kernel. It has kernel-xx-config files that you can directly edit. They will not be overwritten. Perhaps this method is easier. But if you wish to go for the original method, just be extremely precise not to skip any step.

I'm very confused on the right step to use to setup a modified kernel in centOS6. As a simple user, I've downloaded the latests sources (I'm runing an old kernel version) : rpm -i http://vault.centos.org/6.7/updates/Source/SPackages/kernel-2.6.32-573.22.1.el6.src.rpm in the spec file ~/rpmbuild/SPECS/kernel.spec I've set: %define buildid .numa Now I want to set *CONFIG_NUMA_EMU=y* before runing: rpmbuild -bb --without xen --without debug --without debuginfo --target=x86_64 ./SPECS/kernel.spec But where shoud I set this CONFIG_NUMA_EMU option ? I've tested several config files where this options was specified (using grep as a last solution) but each build reset my choice and it is not available in the final kernel. And google is a little bit confusing for me with many and many diverging informations. Thank to kernel gourous for their advices.

But the menu for choosing the camera is greyed as if it was unusable. The message I get in /var/log/messages is: kernel: uvcvideo: Failed to query (GET_DEF) UVC control 6 on unit 2: -110 (exp. 2). each time I launch the cheese application.

[CentOS] Camera doesn't works after yum upgrade
Hi, I've launched a yum upgrade command on a CentOS6 laptop which has updated nearly 600 packages. Automatic updates were not working because of a conflict on a package. So the laptop is now uptodate but the camera did not works after this. The message is: kernel: uvcvideo: Failed to query (GET_DEF) UVC control 6 on unit 2: -110 (exp. 2). The camera is detected as USB, lsusb shows: Bus 001 Device 003: ID 0c45:646b Microdia I've tryed to boot on alternative kernels but no change: - vmlinuz-2.6.32-504.3.3.el6.centos.plus.x86_64 (which solve a camera problem on my laptop) - vmlinuz-2.6.32-431.29.2.el6.x86_64 - vmlinuz-3.10.63-1.el6.elrepo.x86_64 Any idea about a faulty package ? I've added the upgrade log in attachment but it's quite big. The first four erased item were because of conflicts. Some are re-installed after the upgrade (end of the log file) Thanks Patrick -- === | Equipe M.O.S.T. | | | Patrick BEGOU | mailto:patrick.be...@grenoble-inp.fr | | LEGI| | | BP 53 X | Tel 04 76 82 51 35 | | 38041 GRENOBLE CEDEX| Fax 04 76 82 52 71 | === ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It was a previous problem on my personal laptop. The current problem is for the laptop of a student and changing the kernel doesn't solve it. I'm sorry to be confused with tghis information.

[CentOS] Recent version of Latex
I've moved most of my user's PCs from OpenSuse (11.x, unmaintainend now) to CentOS 6.4. On my old OpenSuse latex was texlive-latex-2010 and current version on CTAN is texlive-2013. But on CentOS 6.4 I've only the old texlive-latex-2007 and several sty files available on my previous config are not available now and users cannot compile their previous documents. Is there a Yum repo from where I can install a more uptodate latex environment for CentOS6.4 ?

Re: [CentOS] hung nfs mount
Did you also check /var/log/messages on the nfs server side ? I had some NFS troubles with lockd some times ago and it was a firewall problem on the client: Try: - log on the NFS server and check in /var/log/messages which client is responsible for the problem (it could be an other one than your client). - on this client stop iptables (service iptables stop) and check if the problem still exist. In my configs, client iptables fully trust my NFS server.
