Hello guys, I've just followed this guide http://elrepo.org/tiki/bumblebee and after gnome plymouth I'm getting black screen. Here is my Xorg output: http://hastebin.com/zoyodaxuxu.coffee
I have laptop with optimus technology and centos 7 installed
Bahhumbug
Elrepo components are best supported in #elrepo.

Sornaensis, do you speak russian?

Anyone about to answer a question about centos 1503 btrfs booting pls?
elico
*:ping , anyone awake?
quantic
nope.
elico
quantic: so I was wondering about a project in the middle of the night :\
quantic
what sort of project?
elico
I am looking for one..
         

quantic
oh, you're looking for something to do!
elico
Ho just forgot something :D. I need to build an RPM!
a RPM*
quantic
I think, grammatically, it is "an RPM."
elico
but it starts with a "R".
quantic
elico: With acronyms, it's the sound - not the spelling - that determines which one to use.
elico: Pronouncing the letter "R" sounds like it starts with a vowel, thus "an."
elico
I never knew that.
thanks for the education!
quantic
Every now and then, I'm useful.
elico
I have just found out that a windows 8(year right in this channel) consumes about 1G++ just to check for some updates in some states.
yea*

Anybody have an example of howto boot CentOS7 / RHEL7 iso from Ubuntu 14? Boots part way and halts.
quantic
rjt: How to ... eh? Boot an ISO from inside another OS? Clarify?
elico
rjt: what do you mean boot centos from ubuntu? as a VM?
rjt
@quantic, @elicio Sorry, system without USB nor DVD. Modifying Ubuntu grub2 to boot CentOS7.
quantic
rjt: Ohh. never tried to do that.
elico
do you have the ubuntu running?
rjt
Booting an ISO copied to the HardDisk. https://help.ubuntu.com/community/Grub2/ISOBoot
elico
if so it's pretty simple to use the basic tools.
what ?
ho
rjt
Yes, ubuntu boots up.
elico
and you want the ISO from hdd for installation right?
rjt
The CentOS7 iso halts after finding the mouse.
@elico, yes, to dual boot (long story).
elico
how did you coped the ISO to the HardDisk?
copied*
         

rjt
@elico, scp
elico
well something is weird here
quantic
rjt: Which method are you using from that article?
elico
you cannot boot an ISO(as far as I remeber) from grub, but I am unsure since it is possible with isolinux.
rjt
@elico, i cheated and installed grml-rescueboot (mentioned in article)
quantic
elico: Actually, grub can.
johnfg
Maybe put another way, since it looks like the /etc/pam.d/*.auth files are auto-generated, how do I edit them so as to have them use pam_ldap.so?
rjt
@elico, MultiSystem package installs multiple ISO images to a USB stick and boots them. (Albeit, it may extract some boot files.)
quantic
rjt: Give me a bit and I'll give this a WAG in a VM.
elico
OK then you can but it wont work in all cases? am I right?
quantic: talking about a night project...
rjt
But there are no CentOS nor Fedora examples. https://help.ubuntu.com/community/Grub2/ISOBoot/Examples
quantic
rjt: the CentOS/Fedora ISOs may not be compatible. Let me test.
rjt: What version of Ubuntu and CentOS?
elico
coffee anyone?
johnfg
even the man page for authconfig refers to the system-config-authentication GUI, and that authconfig-tui is deprecated.
rjt
Ubuntu 14.04 CentOS7 /boot/grml/CentOS-7-x86_64-LiveCD-1503.iso
johnfg
But there is no system-config-authentication on centos 7, that I can find.
quantic
rjt: Cool. On it.
rjt: Are you using LVM for your disk, or no?
rjt
@quantic, thank you. i installed grml-rescueboot on a 64 bit Ubuntu. Copied the isos to /boot/grml/, then sudo update-grub
quantic
rjt: Trying to replicate your disk setup. Are you using partitions, or LVM, or just one large partition?
rjt
@quantic, the Ubuntu machine does not use LVM for its system drive.
@quantic, one large partition. Hoping CentOS7 will keep my Ubuntu around. But need the ISO to boot.
quantic
rjt: What filesystem for root?\
rjt
@quantic, ext4
quantic
rjt: Okay, cool.
rjt: Uhh, it's not even slightly bootable for me. Just goes right back to GRUB.
rjt
@quantic, Yes, i had same issue. make a backup of /boot/grub/grub.cfg then edit it, adding linux and initrd lines.
@quantic, linux (loop)/isolinux/vmlinuz0 and initrd=(loop)/initrd0.img root=live:CDLABEL=CentOS-7-livecd-x86_64 rootfstype=auto ro rd.live.image rhgb rd.luks=0 rd.md=0 rd.dm=0
@quantic, inspect the ISO via mount -o loop /boot/grml/CentOS7iso.iso /mnt/somedir; && ls /mnt/somedir
@quantic, we have to get the kernel image and initrd path just right. i have tried so many paths... It would halt after 2 seconds, so initrd is likely bad.
quantic
(Action) does know how to mount an iso...
rjt
@quantic, i'll shut up now.
quantic
rjt: yeah, this is a bit of a pain, huh.
rjt: There it is. It can't load the root filesystem by label for some reason.
rjt
@quantic, i was wondering how to find the label of an ISO.
quantic
rjt: probably isoinfo
rjt: but I don't think that mechanism is going to work in this case.
rjt: I'm going to try something totally different.
rjt
@quantic, the label looked right according to isoinfo and archive mounter.
@quantic, i just rebooted the slumbering HP, so i have to step away to the server room. (So wish i had a decent IP KVM)
quantic
rjt: You can't boot by label with this method, as I've discovered.
rjt
@quantic, http://www.supergrubdisk.org/wiki/Loopback.cfg - wondering if this is saying the ISO image itself has to have something special?

Hi guys, I've got a samba4 Active Directory Domain controller running on centos 7, I'm having trouble shareing the database with bind9 and samba, how can I label "/var/lib/samba/private/sam.ldb.d" so bind and samba can both read the file securely.
fenrus02
just a guess, but https://wiki.samba.org/index.php/Configure_BIND_as_backend_for_Samba_AD#Interaction_with_AppArmor_or_SELinux
Casora
Thanks fenrus02, I followed that guide, and modified it for centos 7, while I got bind9 to work perfect, samba (/var/lib/samba/private/sam.ldb.d/) nolonger can access
fenrus02
does it work in permissive mode?
Casora
fenrus02, yeah it does it seems
fenrus02
does audit2why tell you what the label should be? (frequently does)
Sokel
As a side note... you are more than likely using a compiled /or/ modified RPM's for Samba Domain Controller functionality in EL7. EL7's samba does not not provide primary domain controller capabilities. This could easily be a catalyst for issues in the future.
Casora
Sokel, it's true, I'm using enterprisesamba, however once I get this going I'm going to manually compile it and implement that next.
Sokel
Just know we typically only support what is shipped with centos.

Is CentOS-7-x86_64-Minimal-1503-01.iso a non-LIVE medium
wolfy
bill_lx: as surprising as it may seem, the live media have "Live" in their name,.
bill_lx: there is a readme in the same directory with the isos, please read it as it contains details about each image
bill_lx
Not in all distros - i was checking before i download bcause LIVE don't install on my hardware
Fedora don't use Live in their labels but all are LIVE installs
wolfy: Thanks for replying
darius93
