Hello, I have an older Compaq nc6400 notebook (Centrino Duo). I was able to get up and running under openSUSE TDE KDE with your much appreciated help a few months ago 😁. The old thread is located here -> https://lists.opensuse.org/archives/list/users@lists.opensuse.org/thread/YVX... Some history on the 5.12.0-1-pae kernel (bootabillity issue I experienced) can be located on bugzilla here: -> https://bugzilla.opensuse.org/show_bug.cgi?id=1185542 I have locked the 5.11.16-1.ge06d321-default kernel (after installing the https://download.opensuse.org/repositories/home:/tiwai:/kernel:/5.11/standar... repository). I have been keeping the notebook updated with the "zypper dup" command. uname -a Linux pj-Compaq-nc6400 5.11.16-1.ge06d321-default #1 SMP Thu Apr 22 10:30:16 UTC 2021 (e06d321) i686 i686 i386 GNU/Linux pj@pj-Compaq-nc6400:~> sudo zypper dup [sudo] password for root: Loading repository data...

The following 6 items are locked and will not be changed by any action: Available: kernel-default-base kernel-default-base-rebuild kernel-default-devel Installed: kernel-default kernel-devel kernel-source Nothing to do. 1. I noticed this evening that I was able to select the 5.13.6-1-pae kernel from the boot menu and not only a 5.12.xx series kernel anymore. So I selected the 5.13.6-1-pae kernel and proceeded to boot without failure to the splash screen. I entered my password when prompted at the splash screen and KDE loaded without incident to the welcome screen (This lookout character is excellent 😁). 2. I opened a konsole instance and then entered "uname -a" then "zypper dup". pj@pj-Compaq-nc6400:~> uname -a Linux pj-Compaq-nc6400 5.13.6-1-pae #1 SMP Thu Jul 29 04:18:38 UTC 2021 (2d7b44d) i686 i686 i386 GNU/Linux pj@pj-Compaq-nc6400:~> sudo zypper dup [sudo] password for root: Loading repository data...

The 6 items that I previously locked (I used YaST to do this) may no longer need to be locked. If I decide to operate the machine under the 5.13.6-1-pae kernel. The machine seems to be operating fine with no known issues. I opened YaST and searched pattern "kernel" and there are 3 immediate packages relating to the 5.13.6-1-pae kernel listed as follows: 1a. kernel-default-base - The Standard Kernel - base modules (5.13.6-1.1.21.11) 1b. kernel-default-base-rebuild - Empty package to ensure rebuilding kernel-default-base in OBS (5.13.6-1.121.11) 1c. kernel-default-devel - Development files necessary for rebuilding kernel modules I want to install and lock every possible kernel package relating to 5.13.6-1-pae that can be recommended. I do not see any kernel-source package listed in YaST for 5.13.6-1-pae kernel. Only kernel-source for the 5.11.16-1.1.ge06d321 (installed) and kernel-source-vanilla (uninstalled) are shown under a "kernel sources" search pattern in YaST. 4. Going forward in order to lock the 5.13.6-1-pae kernel I will use YaST. I will need kernel-sources for documentation at some point. Where can this be located and what other kernel related packages can be installed for a more robust experience if necessary? 5. I believe I do not need to uninstall the 5.11.16-1.1.ge06d321 kernel just unlock all 6 of the currently locked packages: -> 1.the kernel-default-base 2.kernel-default-base-rebuild 3.kernel-default-devel 4.kernel-default 5.kernel-devel 6.kernel-source Well, should I just remove everything 5.11.xx related while operating under 5.13.6-1-pae....install and lock kernel-default-base 5.13.6-1.21.11.....*although*....where are it's kernel-sources? Perhaps I should not uninstall or remove the 5.11.xx repository nor packages just unlock the currently locked packages and lock 5.13.6-1.21.11 Perhaps I should leave the 5.11.xx locked as is. I can also lock the 5.13.6-1.21.11 right? zypp.conf is default right now (So It's only holding 3 kernels as per default settings. 6. I hope this is a fairly well written and understandable thread. I wish to get your advice on this situation please. -Best Regards
