[SOLVED]CentOS 6.7 yum update; GPU access blocked by OS

[GShi]

Assuming there is no error, that should do it. (Or you can specify the kernel version to install if you like.)

You are right!!! It solved the issues!!! But I still got some error message and I wanna let you know:

So for the first time:
==============================
yum remove kernel-2.6.32-573.7.1.el6
yum update
==============================
I got 2 error msgs in from "yum update" about conflicts. I attached the pic. And then followed by a bunch of message telling me xx.xxx.package is a duplicate with xx.xx.package.
Apparently, I checked grub.conf and initramfs and the latest kernel wasn't successfuly updated. No signs of any 573 version.



Then for the second time I specify the kernel name:
==============================
yum install kernel-2.6.32-573.7.1.el6
==============================
this time the latest kernel was successfully installed and I checked grub.conf and initramfs and 573 comes back with all .img and initramfs. Then I rebooted the system in 573 version. The graphic interface came back and I ran "nvidia-smi" and it prompts my GPU cards information.


So, apparently, my original issues solved! Thank you very much for your time and patience and teaching me step by step! But also, I am worried about the two conflicts error. Obviously, my "yum update" can't work now...

Let me first say, "Congrats!".

I must go now but there are a number of experts in the forums. I'm sure your current issue is solvable.

Thank you very much! I will dig around online to see if I can solve these problems. But apparently the original problem was done. Thx again!

Your avahi-glib and libxcb are both outdated.
Try yum updating each and post the full yum output.

Hi! Thanks for reading the post and the help! So first, I ran yum list for each to check the version for libxcb and avahi-glib

libxcb:
==================================
Installed Packages
libxcb.i686 1.8.1-1.el6 @base
libxcb.x86_64 1.8.1-1.el6 @base
libxcb.x86_64 1.9.1-3.el6 installed
Available Packages
libxcb.i686 1.9.1-3.el6 base
==================================

avahi-glib:
==================================
Installed Packages
avahi-glib.x86_64 0.6.25-12.el6 @base
avahi-glib.x86_64 0.6.25-15.el6 installed
Available Packages
avahi-glib.i686 0.6.25-15.el6 base
==================================

So I believe both of them is up-to-date. But of course, I can yum update them.

for libxcb, the output is pretty long because it contains error msg about duplicates...

You could try using --skip-broken to work around the problem

I haven't tried "yum update" alone because that would update the whole OS and I am really scared that I will mess things up again.. Thanks again!! Really appreciate that!

[GShi]

oh by the way, I ran "yum clean all" before. But it seemed didn't help. Do I need to remove these two and re-install...?
