why I can't start centos 7.6 sometimes

Hi,

I make centos 7.6 usb-disk, via which CentOS 7.6 is installed. But sometimes CentOS 7.6 can't start correctly, and stopped with the following message:

led to map dmar1
[ 1.881791] nouveau 0000:01:00.0: disp: conn 01:0130: func 00 lookup failed,

What's the problem with CentOS?

Thanks!

Regards

Andrew

safety vulnerability in tablet computer

We discovered safety hardware vulnerability in Samsung tablet computer model SM-T580 16GB SN: R52M20EG5WR – dangerous overheat of the tablet lithium-ion battery caused by short circuit to flash LED, which caused more likely by failed LED controlling hardware. We believe that similar design have other mobile computerized devices utilizing flash LED for digital camera. The computer in question has been in use for only three weeks. The temperature outside of the case was approximately 55C in open space. The LED was shining while the computer was power down.

Diskless Centos & Cgroup config changes

Hi,

I have OS 'image' that boots via PXE and mounts over NFS. (7.5.1804). I am
wanting to explore allowing cgroup usage on this configuration.

The root image is exported read-only over NFS and am using statetab & rwtab
to allow some persistent parts of the filesystem as well as read/write
where needed.

I have tried setting /sys in the statetab and this causes the machine to
fail, as I have tried /sys in the rwtab. The latter increases the boot time
to a point which is not usable.

Updateinfo file is not valid XML

Hi,

Since last night, all my servers spew out the following error when

upgrade to kernel 4.19.43 fail.

Hi all...

I just upgraded to laatest kernel in experimental from 4.19.40 ,
and for my OpenCL app this now fails with this msg:

amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x.

Booting back to 4.19.40 makes it work again.

I have added a few files from amdgpu-pro package, to make openCL work
here in centos7; but something must have changed in this new kernel for
amdgpu support.

As kernel 4.19.40 works fine, it is not a big issue here - just wanted
to report it.

Allan.

how to change all hardware and system-IDs

Hallo,
has anyone a hint how to change all device-IDs in a cloned Centos-VM.

Using a live-cd is possible.

Thanks for hints

Thank you for your time.

UEFI boot manager sequence problems HP Envy

Morning all,

I have a HP Envy dual boot system (Win8 for serious stuff, i.e. Train Sim and Flight Sim) and Centos 7 for everything else.

In the past I've had the occasional problem where an update on the windows side has updated the UEFI boot sequence but using efibootmgr has always fixed it.

On Friday I discovered that my HDD was failing so I tried using Clonezilla to move it on to a new SSD of the same size. Unfortunately the clone didn't work, failing half way through my main partition.

Older versions of samba that work with CentOS 7?

Hi.

Are there any places I can download older versions of Samba working with CentOS 7?

Reason:

I have been upgrading all of my servers from 6.X to 7.X.
This alone is a massive task for me as I am a one man band.

Samba made massive changes not allowing NT style domains anymore in the 4.10 branch.

If I can find older samba RPM's for CentOS 7 than I can finish all upgrades of the OS, then later upgrade samba once I am finished when I have more time.

Any ideas anyone?

thanks

Bash completion thrown by quoted option args?

There was a thread about C7 bash completion back in August last year, but it doesn't have answers for this problem.

Example: "yum install /path/to/local/package" works fine with tab completion to fill in the path and package bits.

However, "yum --debuglevel="1" install ..." just gets stuck and doesn't offer anything. The only option is to type everything out, or type enough to use a wildcard. After more testing, I found that any option argument that is quoted breaks completion. Which in turn makes me think this is not even specific to yum but bash completion in general.

system unresponsive

Ok, we used to get this occasionally on cluster nodes, and we just got it
on a fileserver (very bad). The system is discovered to be unresponsive:
it doesn't ping, and plugging a console in, you can see that it's not
dead, but there nothing at all on the screen, nor does it respond to even
<ctrl-alt-del>. The only answer is to power cycle it; it comes up fine.

Nothing in /var/log/dmesg or /var/log/messages. No abrts I can find. sar

Bypassing 'A stop job is running' when rebooting CentOS 7

I'm currently trying to reboot a CentOS 7.5 workstation (to complete an
upgrade to 7.6), but it is 'stuck' while shutting down with 'A stop job
is running for ...' - the counter initially gave a limit of '1min 30s' -
but each time it reaches that limit, it just adds on ~90 seconds to the
limit ...

Currently the limit is '25min 33s'

I'm in no hurry to have this workstation operational, but I guess at
some point I will have to power cycle it ...

Does anyone know how to bypass this?

bad install

I tried to install Centos on a partition of a Windows machine, and I
screwed up. Thinking that the installation would take a while, I took a
short break. When I

came back, the install was "done" but it is now asking for a password
that I never gave it. I can't get around this. I tried to reinstall from
the DVD I downloaded,

but it just comes up "password" instead of letting the DVD mount. I
tried to reformat the partition (sda6) using gparted, but the section
that contains the

problem does not reformat, it remains there.

Rhel8 guest and window resizing (possible OT)

I have installed a redhat 8 server in a KVM/Qemu VM guest to prepare for

with incompatible versions of spice or is there something else besides
the spice daemon that I should be looking at.  Does this work correctly
under CentOS 6 & 7 Host?

Opera browser on CentOS

Is anyone running the Opera browser on Centos 7 or 6? While not available in a yum-repository, it seems to be available as a snap-package. Not familiar with those yet but curious if the browser is worthwhile to run. I have generally found Firefox less useful/compatible than Chromium but would also like alternatives, particularly since Opera defaults to a VPN-connection.

CentOS 6/EPel: Missing EPel package?

The EPel repo has a *nearly* complete collection of QT5 packages. One
important one that *seems* to be missing: qmake.

There does not seem to be a package containing qmake in the collection of QT5
packages for CentOS 6!

I guess I can find the source code and build it (somehow)...

bash off topic

I have a simple bash script it will take arguments from a file that has
quotes.

my file arg.txt would be this
-lt "*.txt"

my script file would be
LS_ARG=`cat arg.txt`
ls $LS_ARG

it does not run properly:
sh -x ./arg.sh
++ cat arg.txt
+ LS_ARG='-lt "*.txt"'
+ ls -lt '"*.txt"'
ls: cannot access "*.txt": No such file or directory

How do I resolve that ? If the quotes are not in my file it all works
fine. I think its because it looks like the extra single quotes it puts
around the "*.txt" - or - '"*.txt"' - how do I do this ?

centos 7 gnome-terminal login-shell

Hi !

I wonder, that i got a login shell, if i start the gnome-terminal on my Gnome-Desktop,
recognizing the sourcing of all files in /etc/profile.d/ ..

Can somebody give me an hint, where it's system-wide configured or it's a
bug and it isn't configurable ?

(it's not configured as login-shell in Preferences and the checkbox ;-) )

For Ubuntu18.04 it's not the default, but the Checkbox for login-shell works there like a charme ...

I see openjfx at openjfx.io. I assume that if this version is appropriate

Firefox esr repackage

Hi everyone, I use firefox on centos 7 at work but due to the fairly well know extension signing problem, I cannot use ublock origin.

It looks like Mozilla have just released firefox esr 60.6.2 which should fix the signing issue.

What happened if install a el7 package on a el6 system

Hi,

Recently, I encountered a interesting phenomenon that CentOS 6.3
running as normal even if I (my colleague, actually) installed a
kernel that build for CentOS 7.x (e.g. kernel-3.10.0-327.el7.x86_64.rpm).

I found kernel is mismatch accidentally when I using "uname -r" to
check kernel version. So my question is what the harmness we will
get if I install a el7 rpm into a el6 system?

yum remove iptables problem

Hi

Just got a new server replacing another server.
I had to use iptables to protect it until I could move a hardware firewall from the old server to the new server.

Now I am trying to delete iptables but it wants to delete lots of other dependency packages, e.g. sendmail, cyrus-sasl and even plymouth.

Can I just use "force" and "no-dependecies" to get rid of it?
Are there other implications I do not know about?

Firefox addons disabled - temporary fix

The currently available fix for Firefox doesn't work with ESR, but there's a temporary fix that works. At least, it's working for me:

Go to about:config and set xpinstall.signatures.required to false.

The Firefox folks say that a fix for ESR will be coming at some point, but at least this gets things working again in the short term.

It's not clear to me if the fixed ESR (when available) will require a new Firefox rpm to be created and installed or if it's something that will just show up by magic and start working or if any steps will have to be taken to enable it.

HERE document in docker script file

I am trying to use a HERE document in a docker script file to generate a text file but must be doing something wrong since I get a warning message that I did not expect:

EOF: line 6: warning: here-document at line 0 delimited by end-of-file (wanted `EOF')

This is the sample script I am testing in my docker file:

RUN bash -c "$(/bin/echo -e "cat << 'EOF' | tee -a /test.txt \
    \n<test> \
    \n  someting here \
    \n  something else here \
    \n</test>")" \
EOF

Can anyone see what is wrong in the above statement?

Thanks.

"Untrusted application launcher (desktop launchers)"

I am having this problem on Ubuntu 18.04 -- I manage a batch of desktop
machines with some convience desktop launchers, which gnome3 insists are
"untrusted". With some general websearching reveals that this is a *GNome3*
so-called "security" issue
(<a href="https://gitlab.gnome.org/GNOME/nautilus/commit/1630f5348" title="https://gitlab.gnome.org/GNOME/nautilus/commit/1630f5348">https://gitlab.gnome.org/GNOME/nautilus/commit/1630f5348</a>).

CentOS 7, KDE, Dolphin and MTP support

Hi,

It looks like KDE's file manager Dolphin doesn't support MTP under
CentOS 7. When I plug in an MTP device like my Nikon camera or an
Android phone, Digikam shows its content OK, but Dolphin seems to ignore
it.

For now, my custom CentOS 7 + KDE desktop meets about 99 % of my needs.
Now I've decided to tackle the remaining 1 %.
