Help! #Boot / #GRUB advice:

I have a relatively new laptop. Recently when rebooting it just went to the GRUB bash-like interface rather than booting.

99 times out of 100 when rebooting the laptop doesn't recognize any USB key is plugged in and goes straight to GRUB recovery. #EFI boot sees the drives EFI files though.

1 in 100 times the whole thing boots just fine from either the drive or USB key.

BIOS hard drive diagnostics says it's fine.

Any ideas how to troubleshoot?

For the HP Prodesk G4 (and other HP models) if the Keyboard or Mouse isn't working in the UEFI Firmware or Grub menus the workaround in the JetKVM is to go to:

Hardware -> Settings -> USB Devices

and select Keyboard Only in Classes.

There is something wonky with HP devices USB HID support at Boot that means it won't detect JetKVM USB HID devices if the Classes option is set to more than one item in the Classes list.

Weird 🤔🤷‍♂️

Yes, #slackware current includes #Landlock support in the testing group with #kernel 6.14.
However, you must enable it at boot. If you're using #GRUB, follow these steps:

1. Add the following line to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="lsm=landlock"

2. Regenerate the GRUB configuration:

geninitrd

3. Reboot your system and verify that Landlock is enabled:

sudo dmesg | grep landlock

Example output:

[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-generic root=UUID=... ro lsm=landlock
[ 0.068388] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-generic root=UUID=... ro lsm=landlock
[ 0.212270] LSM: initializing lsm=capability,landlock
[ 0.212270] landlock: Up and running.

Once enabled, you can use landrun on Slackware-current:

I've installed Linux Mint Debian Edition onto one of my machines! I have been using Mint (the one made using Ubuntu) for about a decade and I'm happy to finally cut #Amazon out of the loop.

Linux Mint Debian Edition (LMDE) feels almost exactly like Linux Mint. The only difference I've noticed is that it asks me about the GRUB bootloader more at setup than I recall from Linux Mint.

If all continues to go well with my first machine, I'll be switching the other machines to Debian Edition, as well.

I had a hard time finding information on the differences between specifically Debian and LMDE online that wasn't just AI-generated clickbait garbage, but I have the general impression that LMDE has more set up for me at the outset, which is what I prefer.

So, what to do? First, enter in the 3rd OS (Open SUSE) (before going in Windows!!!) and copy the contents being in /boot/grub/grub.cfg (to use in the 2nd OS, so use some Internet or USB or whatever). Second, in the 2nd OS (Debian-like) paste those contents in a new file /boot/grub/custom.cfg (see forums.debian.net/viewtopic.ph, forums.debian.net/viewtopic.ph) And 3rd, it is possible you have to replace in that file the entries /boot with entries /@/boot (forums.opensuse.org/t/trying-t).

You can check this in the grub: press c to enter in the command line tool, press ls -l to see the partitions, and for example if (hd0,gpt1) is one of them, 'ls (hd0,gpt1)'+tab will show you the possible paths, being of the form '/boot' or being first '/@' and then '/@/boot'..

Anyway, I got Open SUSE Tumbleweed installed and accessible with Debian Grub2 after all the previous afternoon+evening+night looking for a solution.

forums.debian.net[Solved] Debian grub does not find Fedora - Debian User Forums

Assume you have Windows on your computer (as most of computers bring by default), assume you also have a dual boot with Debian or some other Debian-like OS (Ubuntu, Mint, ...) and you manage it with Grub2. Now, let's assume you install a third OS, like for example Open Suse Tumbleweed. It may happen 1) the new Grub2 you see when starting the computer is the one coming with the 3rd OS (Open Suse...); 2) if you enter in Windows and restart the computer... you find the terrible surprise that there is no more Grub2 and it enters straight to Windows; and 3) update-grub in the 2nd OS (Debian-like) does not detect the 3rd OS (Open Suse)...; and 4) after many attemts you solve neither 2) nor 3).
