gtk3 update causing havoc
by Paul Johnson 25 Sep '17

25 Sep '17

On my lab systems, the automatic updates were failing because of the problems with ipod libraries from EPEL being in the way. It turns out that was a good thing, because when I "fixed" it, a massive set of packages was updated, including the new gtk3. These packages are the ones causing problems, I think. gtk3-3.22.10-4.el7.x86_64 gtk3-devel-3.22.10-4.el7.x86_64 In the release notes, there is mention of the "giant icon" problem and how to fix that. We understand that part. The bad problem I see now is that Emacs and Chromium-browser, which rely on gtk3 don't work properly anymore. In Emacs, the symptom is that the ribbon of buttons under the pull down menu will no longer show. In Chromium, the buttons and other widget things on the top are an ugly yellow distortion. I've recompiled the Emacs that comes with EL7, as well as 24.5, and the Emacs behaves the same way, no buttons show. The buttons are invisible, but still there. If you click in there, you can get lucky. Do you see it too in Emacs? I see some posts that say the Gnome themes don't work any more with GTK and those themes should have been deprecated by the gtk3 packages. I don't think the theme is the cause because I see same problem in both Gnome and XFCE4 desktops. I see it also if I SSH into the machine and run emacs forwarded over X11. I just realized that on Ubuntu I'm running gtk-3.22.11 with Emacs 24.5 and the icons do show. Maybe there is a change in the compiler flag for Emacs that I'm missing. pj -- Paul E.

7.4 network issues
by Alice Wonder 25 Sep '17

25 Sep '17

Two onboard nics, Intel, eno1 and eno2 If either of them is set to onboot then network won't start. one error message says :bad vendor preset disabled Another error message (in red) says Failed to start LSB If I can find a USB key there is an updated kmod-wl src.rpm that *may* bring up my wifi, but I am not sure I have access to a USB key at the moment. The motherboard is supermicro and the onboard nics are Intel which I thought were well supported, but I do remember going from 7.2 to 7.3 on a server IPv6 was bricked because of changes to how the /sbin/ifconfig scripts were configured. This one (is a xeon, server board, but its my desktop) I think started life as 7.2 and was at 7.3 before this update - in case there's a similar issue with incompatibilities with config file after update. I've not used the nics before, always just used wifi. What's the secret to getting them to connect via dhcp onboot at least long enough to try and get the broadcom wifi working again? -- -=- Sent my from my laptop, may not be able to respond timely

Bricked my system
by Alice Wonder 25 Sep '17

25 Sep '17

Updated to CentOS 7.4 No wifi. The wifi was using wl-something driver that had third party firmware but it wasn't seen. Attempted to get network with ethernet from the mobo to router but it wouldn't come up. So I rebuilt the wl-whatever kernel module and installed the updated version built against the newer kernel. Now when attempting to boot it gets stuck at "i8042 no controller found" and stops. That message is always there, either lack of serial port or lack of PS/2 ports - I forget - but the boot now hangs there. It's caused by the wl-whatever kmod update I tried trying to get network back, but I can't remove that rpm if I can't boot. Help. -- -=- Sent my from my laptop, may not be able to respond timely

yum groupinstall vs. yum group install
by Nicolas Kovacs 25 Sep '17

25 Sep '17

Hi, Is there a difference between 'yum groupinstall' and 'yum group install'? As far as I can tell, # yum groupinstall "X Window System" and # yum group install "X Window System" get me the same result. Just curious.

But the good news is, I've booted a few Linux Live CDs, and I think I'll just replace Mac OS X with CentOS 7, if possible. Anyone here with experience on installing CentOS on a MacBook Pro? This model is from 2009. As far as I know (correct me if I'm wrong), Apple hardware always uses EFI. What can I expect? Flawless installation or countless hours of suffering due to completely unexpected problems?

upgrade or install to Centos 7.4.1708
by Pete Geenhuizen 25 Sep '17

25 Sep '17

I upgraded from 7.3 to 7.4 over the weekend. Everything went well except that I can't login because the screen is black with a cursor. If reboot boot the 7.3 kernel 3.10.0-514.26.2.el7.x86_64 kernel everything works just fine, so my guess is that there's a kernel issue with the hardware, specifically the Skylake processor. Has anyone else run into this problem and if so can how I resolve the problem other than using the previous kernel? ASUSTeK COMPUTER INC. Z170M-PLUS VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz Skylake Any help with this would be greatly appreciated.

The answer is to recompile the source tarball with a patch which appeared at: https://communities.vmware.com/message/2686431?tstart=0#2686431 generously provided by https://communities.vmware.com/people/dariusd . Tried it and it works swimmingly.

Hi, how do I allow lighttpd access to a directory like this: dr-xrwxr-x. lighttpd example unconfined_u:object_r:samba_share_t:s0 files_articles I tried to create and install a selinux module, and it didn´t work.

Being like this, selinux is entirely unmanagable. Does it even do any more good than it keeps getting in the way?

[Slightly OT] Use CentOS to create a bootable Mac OS X DVD from dmg file?
by Nicolas Kovacs 24 Sep '17

24 Sep '17

Hi, Sorry if this is only half-CentOS-related. In my office, I'm running CentOS on all my systems (server, workstation, laptop, sandbox PCs). A colleague brought me her MacBook Pro to upgrade it from OS X 10.5.7 to 10.11.6. I downloaded the 5.8 GB dmg file and now I wonder how to create a bootable DVD with this using only Linux tools. 1. Can I simply burn this as a data DVD with K3B? 2. Or do I have to jump through burning loops using dmg2img, mount -t hfsplus, etc. I only have a couple of double layer DVDs here, so before burning a pair of expensive coasters, I thought I'd rather ask here.

Connecting to internet with USB tethered iphone
by Larry Martell 24 Sep '17

24 Sep '17

I am trying to get a centos 6 system on the internet with a tethered iPhone. I can see the phone with lsusb as bus 001 device 011. A post on stackoverflow said I would need to run "# ip link set usb0 up && dhcpcd usb0" But how do I reference my phone in that command?
