Upgrade To 8.4 .2105 Problems

The yum upgrade from 8.3 to 8.4 on my main machine  looked as if it was working fine so I went to have a coffee.

When I came back the screens were blank so I don’t know what happened. On rebooting the screens are still blank.

I have two graphics cards running three displays.

I have a “rescue” system on the same machine that upgraded from 8.3 to
8.4 fine. The 3 screens work fine on this.

I am not sure the upgrade completed properly. For example the new kernel:

 vmlinuz-4.18.0-305.3.1.el8.x86_64

was not present in /boot. Even worse, “yum upgrade” said there was nothing to do and would not install it. I installed the kernel package manually.  /etc/redhat-release says CentOS Linux release 8.4.2105

My main question is: Where are the config files for the screen(s). This used to be something like /etc/X11/xorg.conf.

Since I have a working rescue system my current plan is to compare/copy the config files.

Suggestions please as to where I should start. It is difficult to work without a GUI. I have SSH access to the machine.

Thanks

  • I noticed in journalctl that gnome-shell was core dumping.

    yum reinstall gnome-shell fixed my displays problem.

    So I am back to my first premise that the ‘yum update’ did not complete properly for some reason.

    Is there any way I can check the integrity of the packages installed?

    What could cause ‘yum upgrade’ to say ‘Nothing to do’ and not install the latest 305 kernel?

  • rpm, but not to my knowledge, has a “verify” command.

    It checks all files from the specified package are present and compares 9 properties with the original specs.

  • Thank you.

    I managed:

    but rpm -Va is neater. It only showed up config files and the like that you would expect to be different.

    I’ll check the list of rpms next against a clean install/upgrade to make sure I have them all.

  • Additionally checks can be done with (its in yum-utils package):

    package-cleanup –problems

    package-cleanup –dupes

    # dnf remove –duplicates
