I think the root cause of the problem is that you have upgraded multiple 
times, and somewhere along the way (maybe around the F25 timeframe), the 
management of the rescue image and its grub entry got lost by the 
release and testing teams, and never removed or upgraded.  It is still 
there and not getting cleaned up by any of the upgrades, but waay out of 
date and missing more than a few critical bits now.  This is probably 
one of the casualties of allowing testing on VMs instead of real 
machines and insufficient release acceptance criteria.  So for your 
situation, its dead, Jim.
You may be able to recover using the install media like you can in 
Ubuntu or Debian or Slackware, but I had no luck with keeping the 
filesystem contents intact using the default one-disk layout on Fedora 
30.  I probably didn't have the obscure document available on how to 
actually do this, so YMMV of course.
Failing that and assuming that you don;t have a petabyte or so of LVM 
content, it may be possible to mount the existing LVM volumes from the 
install media, in order to copy off a backup of what you need to keep 
undamaged, and reinstall from scratch.


So many things wrong with that...

1. The rescue images don't get updated automatically.  You have to 
delete the existing one and then a new will be created.
2. The default install is a separate filesystem for /home so even a full 
reinstall won't damage your user files.
3. He doesn't actually have a problem right now, he's trying to plan 
ahead in case something does happen in the future.

That's probably not what you think it is.  By default the initrds have a 
very limited number of drivers, intended to be the minimum required to 
boot the current hardware.  The rescue image has the full complement of 
drivers so that if you change your hardware or move the drive to a 
different computer, you will still be able to boot it.  Unfortunately, 
that initrd is never rebuilt with newer kernels and also doesn't 
necessarily include 3rd party drivers.


My preference is for the rescue mode to use the most recent release 
practical up to and including f30 (not 31!).  I do now have Fedora live

How do I rescue the rescue mode?


If you delete the existing rescue kernel and initrd from /boot, the next 
kernel install will generate a new one.  However, what you're really 
looking for, you already have with the live boot.  If you boot from the 
live image, in the grub menu is a troubleshooting submenu. In there 
you'll find the memtester option.

If you read the rest of the thread, the problem was unrelated to the
Steam installation as such. It just needed a BIOS tweak. However for
the moment I'm not pursuing this until there's a reliable way of
sharing game installs between Linux (Proton) and my Windows VM.

just a question, not a problem. Whenever that screensaver begins to move

What are they? Is there a setting for that screensaver that makes

I looked on jwz.org, but didn't see a link from which to ask such

I've been running Steam on Fedora for two years now and it's worked
just fine. At first I had a GTX 1060 6GB. Last December I upgraded to

As far as I know this resume option is only used when resuming: it
doesn't affect normal boot. The UUID should be the one of the swap

I think the stanza will be instead in /boot/loader/entries/* except
perhaps if the machine is multi-boot and then grub2-mkconfig generates
legacy menu entries in the /etc/grub.d/30_os-prober section

rescue mode needs rescuing!

2020-03-14 Thread home user

(stand-alone home workstation; f30; Gnome)

Well, as I noted when I closed the "prep. for upgrade." thread, I'm 
getting hints of hardware trouble.  I thought I'd start by testing 
memory (memtester).  My understanding is that it's best to do that with 
as little else as possible running.  So I re-booted.  In the grub menu, 
I chose the line

"Fedora (0-rescue-[32 hex digits]) 30 (Thirty)"
which is the 4th line in my grub menu.  A thick line of various shades 
of a bluish color appeared at the bottom of the screen, with "Fedora 19" 
at the right end.  The line turned white starting from the left end, 
working slowly towards the right. Then in the middle of the screen, the 
message

"NVIDIA kernel module missing.  Falling back to nouveau"
appeared.  Nothing else happened for over 5 minutes, at which point I 
did a manual hard reset.


1. The grub menu entry and the boot progress line contradict each other.
2. The rescue mode fails to completely boot.

My preference is for the rescue mode to use the most recent release 
practical up to and including f30 (not 31!).  I do now have Fedora live 
on a USB stick, but as I noted (in different words) when I closed the 
"prep. for upgrade" thread, it's glitchy.  So I'd like to have this 
second fall-back.


How do I rescue the rescue mode?

Samuel has already answered your question to your satisfaction, so this
is just for future reference.  At this point you could have used
man mount
to see how mount works.  With your background you are fully capable of
resolving simple errors like this.  Mount doesn't create the mount
point, so my memory was faulty and the mount point didn't already
exist.  Samuel got around this by using plain /mnt, as that always
exists, but if there is anything else trying to use /mnt/[some
directory], that will cause problems (unlikely from an ISO, though).

Something that has worked for me in the past is to chroot to the
installed system as you already are and then run
dnf update
to bring the system fully up to date.  Often that will resolve a
problem.

But all this is irrelevant if the problem is hardware.

Are you really trying to resume instead of booting from the installed
system?

As Francis already said, you are still booting using legacy grub, so
your grub.cfg will be in /boot/grub2/ as grub.cfg.  Maybe you could
show the boot stanza from that file here?

If you want to boot from the grub.cfg you should comment out the above
GRUB_CMDLINE_LINUX and replace it with the one from the most recent
entry in the /boot/grub2/grub.cfg file.  Then rerun the 
grub2-mkconfig -o grub.cfg file in the /boot/grub2 directory.

I think this is because of the resume from hibernate.

We trust you have received the usual lecture from the local System

So now I can do "rooty" things in the workstation hard drive when using 
Fedora live.  I might need this soon


A few times while trying to use Fedora live, the workstation froze while 
in Firefox.
A few times, Fedora live did not shut down properly; and the cooling fan 
surged; and I had to do a hard manual shutdown.
Twice, very early in boot-up, before the grub menu appeared, a warning 
about the cpu being hot appeared.
Thursday, I had to go into windows-7 briefly to see if my board was bios 
or uefi; it froze during shutdown.


Both Samuel and Tim have made suggestions and asked questions that I 
want to follow up on.  But with hints of hardware trouble, I need to 
turn my attention to the hardware.  I'll open a new thread on that.


The questions I asked when starting this thread are answered.  I thank 
those who tried to help for their time and effort.  I've marked this 
thread "SOLVED".


Bill.

Re: GRUB2 removing args "quiet" "rhgb" - grubby doesn't work

With this, grub2-mkconfig will generate in /boot/grub2/grub.cfg (your
previous trace shows that your machine is not using EFI):

### BEGIN /etc/grub.d/10_linux ###
...
# The blscfg command parses the BootLoaderSpec files stored in
# /boot/loader/entries and populates the boot menu. Please refer to
# the Boot Loader Specification documentation for the files format:
# https://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/.

set default_kernelopts="root=UUID=XXX YYY"

insmod blscfg
blscfg
### END /etc/grub.d/10_linux ###

Where XXX is the UUID of the rppt filesystem, and YYY is deduced from
GRUB_CMDLINE_LINUX present in /etc/default/grub
Ex: 

  set default_kernelopts="root=UUID=509e4d95-a5f5-40e6-94e9-8bbff77f32cd 
resume=/dev/disk/by-uuid/d16bbc09-698b-4e97-9aa0-c37328b36422 "

then, in my case, the /boot/loader/entries/* files only use the
default_kernelopts

Ex:

  title Fedora (5.5.6-201.fc31.x86_64) 31 (Thirty One)
  version 5.5.6-201.fc31.x86_64
  linux /boot/vmlinuz-5.5.6-201.fc31.x86_64
  initrd /boot/initramfs-5.5.6-201.fc31.x86_64.img
  options $kernelopts
  grub_users $grub_users
  grub_arg --unrestricted
  grub_class kernel


Check if those files differ from mine, ex: set options differently.

Have you checked /boot/grub2/device.map ?

Did that but I still don't get the verbose boot . .


then check after an addional run of the above "...grub2-mkconfig..."-
command if the boot files have changed => new date/time:

sudo -s

=> reboot

Odd thing: the grub menu font looks about double size . .

"Probing EDD . . ." - also in double size font

"Probing EDD . . ." - then changes to normal size font

but still not other text on the screen till the F31 login prompt . .

Thanks,

Phil.
