similar to: Centos-7.2 LiveKDE does not work properly

CentOS-7-x86_64-LiveKDE-1511.iso crashes on my AMD/ATI Radeon machine. I installed CentOS-7.2 by first installing CentOS-7-x86_64-LiveKDE-1503.iso, then appending GRUB_CMDLINE_LINUX_DEFAULT="initcall_blacklist=clocksource_done_booting" to /etc/default/grub and running update-grub. My question is: would there be any way, short of re-compiling the ISO, of altering the grub.cfg seen when

I've installed CentOS-7-x86_64-LiveKDE-1503.iso and CentOS-7-x86_64-LiveKDE-1511.iso on two USB sticks. The first boots up in 90 seconds, but the second takes almost 7 minutes. (I'm talking about the time until my laptop becomes usable.) After 5 minutes a small window comes up saying it cannot save bookmarks because it does not have permission in the required directory. I assume the

If I boot into CentOS on my home server from a Live CD or USB stick and go to Troubleshoot, it lists OS's it finds on the machine. How does it find these OS's? Presumably it looks through all the partitions on all the hard disks for something that looks like an OS? But how exactly does it identify an OS? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College,

When I re-booted my HP MicroServer into CentOS-7.2 I was given a text console.

My HP MicroServer crashes with a kernel panic when booted into kernel-3.10.0-327.3.1.el7.x86_64, but runs perfectly under kernel-3.10.0-229.20.1.el7.x86_64 . I've been trying to save the panic message with kdump, but am not sure how one can configure kdump to do this, if indeed that is possible. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

This, IMHO, is one of the more annoying bugs with the newer GRUB (which i assume is the bootloader you are using). Specifically the newer grub can't, won't boot from a drive other than the one grub is on. suggest you revert to grub 0.97 or, if any boot loader is or can be put on the drive with the 6.5 distro you can make that drive the boot drive in the bios, which is how i do it. i.e.

Probably. The fact remains that booting was attractive, and now it isn't. --

I'm trying to install spamassassin on a postfix/dovecot server, running CentOS-6.4, following the instructions at <http://wiki.centos.org/HowTos/Amavisd>. I think I have taken all the steps indicated, and the configuration seems to pass the tests suggested, although the response is much more sparse than that described: ------------------------ [tim at alfred ~]$ telnet localhost 10024

Has the CentOS logo disappeared from CentOS-7? I thought the logo in CentOS-6 was very pleasant. Also I liked the way in which one increasing circle inside another showed how the boot was progressing. The dots going round and round in Microsoft fashion in CentOS-7 is a retrograde step, I think. One always has the fear it might continue forever. -- Timothy Murphy gayleard /at/ eircom.net School

I'm running postfix + dovecot on my CentOS-7 home server.

when I ran "sudo yum update" on my CentOS-7.2.1511 today, ddclient was updated to ddclient-3.8.3-1.el7.noarch (from 3.7.3), and ddclient.conf was moved to ddclient.conf.rpmsave . When I move it back, "sudo systemctl restart ddclient" fails with the error (in "sudo journalctl -xe | grep ddclient") Apr 21 13:05:39 alfred.gayleard.eu.localdomain touch[8590]:

I have a remote home server updated to CentOS-7.2.1511 (as stated in /etc/redhat-release) but I have not re-booted since the update. The machine is currently running kernel 3.10.0-229.11.1.el7.x86_64. I'm wondering if anyone has advice on any safety steps I can take before re-booting, so that in the event of failure I can give simple instructions to my daughter at the other end on how to get

I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

My CentOS-7 home server has a static IP address. Is there a simple way of organizing the hpptd server so that it is accessible through this address at a remote host, but is accessed at its 192.168 address by a laptop on the WiFi LAN? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

I have a working CentOS-7 machine. I want to install grub2 on a USB stick (without altering my present system in any way) so that I can boot the present system from the USB stick. Could some kind (and expert) soul explain precisely what to do. If it were possible to boot other systems on the computer as well that would be an added bonus. I did google for this, but all the sites I saw wanted to
