Re: [CentOS] VNC into CentOS 7.4

[Eliezer Croitoru]

This is a question should be asked about any VMware system and not just
vmplayer.
This issue exists on any version with the combination of either RDP or VNC
for a very long time when using they GUI such as vsphere client.

Subject: [CentOS] VNC into CentOS 7.4

When I VNC into 7.4 everything is fine until I run vmplayer (VMware).
The vmplayer runs but when I type on the console for vmplayer which is also
running a centos image I get multiple key presses - sometimes. Its not
everytime - but enough to be annoying.

How do I take care of that ?

Re: [CentOS] Gnome dark panels

Log out and there will be a setting in the login screen where you can
change your desktop environments. There you can choose GNOME 3 (Not GNOME 3
Classic)

I checked with a Red Hat Enterprise Linux system and the problem
occurs in that also. I have opened

included since you did all the work.

I'll figure that out later. I found a USB key in my camera bag (I'm out

I need to get an Intel wireless nic with drivers in the kernel, that's

I'll figure out what's up with the wired connections later.

[CentOS] 7.4 network issues

[Alice Wonder]

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?

Re: [CentOS] Bricked my system

[Alice Wonder]

I got in and removed that kmod and got it booted.

Now I have to figure it out why it won't connect via ethernet even 
though its set to DHCP and should.


Seems every major CentOS update changes the network stuff in a way that 
causes headaches. That's probably just my frustration speaking but 
that's what it feels like.

[CentOS] Bricked my system

[Alice Wonder]

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.

[CentOS] System shutdown on OOM

[Thomas Plant]

Hello all,

had an issue on with a virtualmachine on XenServer 7.0 yesterday. It is 
a Centos 7.4.1708 and in a OOM situation it just shut down.

No kernel panic where I could see a message, but it just turned itself off.

All I could see in the /var/log/messages was the following:

Sep 24 03:11:08 hostname xe-daemon: Running CollectDisk ...

Anybody seen this before? Is there a way to configure it so that it does 
a reboot instead of a shutdown?

[CentOS] yum groupinstall vs. yum group install

[Nicolas Kovacs]

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.

Re: [CentOS] [Slightly OT] Use CentOS to create a bootable Mac OS X DVD from dmg file?

With CentOS 7 I only had one problem, which proved to be a showstopper.
Normally I'm running a highly customized version of KDE on all my CentOS
desktop installations (installation is described in detail on my blog at
https://blog.microlinux.fr/poste-de-travail-centos-7/). On the MacBook
Pro, KDE simply froze at startup. The KDE splash screen would show the
first hard disk icon, then there would be a little chime, and that's it,
freeze.

I've already seen this behavior on other older laptops, and a peek in
/var/log/Xorg.0.log showed me that the card couldn't render the desired
effects (don't remember the exact error message). And this even though I
had installed the proprietary NVidia driver.

The thing would probably have worked with Xfce or MATE, but I had a
strict time limit for that installation. Ubuntu 16.04 worked pretty much
out of the box - and is nice to look at - so I decided to go with that.
Next time I'll give CentOS 7 + custom Xfce a spin.

Cheers,

Niki
