Probably going to happen. Going to postpone this switch and thanks for 
clarifying.

Oh, I thought you were saying grub in general on UEFI systems was 
unsafe. Makes sense now.

Re: [qubes-users] F2 stoped working after last kernel update

Could not find a solution how, if even possible to pick which kernel to
boot or/and modify kernel parameters before booting like i am used from
grub by pressing 'e'.
Does UEFI Boot support this or/and how can i safely switch my setup to grub
boot? I would like to see what happens when i remove the plymouth option (:


UEFI boot doesn't support on-the-fly modifications like grub. You can
edit that xen.cfg and change the default= to a different entry, but it
won't take effect until next boot. It might be possible to switch boot
to grub, but I wouldn't call it "safe". Some of the new systems only
support UEFI booting, for example, so switching to grub might break boot.


Doesn't grub support UEFI? That is, can't the firmware's UEFI loader 
load grub in UEFI mode (grub.efi), which can then boot other OSes just 
like it does in legacy mode (with menu, command line, config editor 
etc)? So grub should work fine on a UEFI-only machine, shouldn't it?


Actually, I found that if you install qubes on another partition on a 
machine that already has qubes (or maybe any OS), (perhaps only if they 
share a /boot), the qubes installer will enable grub (the UEFI entry 
becomes grub.efi instead of xen.efi). And I'm pretty sure legacy boot 
was disabled when I did it.


So I'm not sure why it would be unsafe. In fact I'm thinking about 
manually enabling grub (in UEFI mode) just to ease troubleshooting in 
the future should I ever run into any boot issues. Just my take, but I 
could be wrong.

to grub, but I wouldn't call it "safe". Some of the new systems only

However, as long as you have a Live boot image of some type nearby, you
can try edits in your xen.cfg. If it breaks something, boot the Live
image, mount your drive, and edit xen.cfg back. Looks like
https://github.com/QubesOS/qubes-issues/issues/3849 is why it got added,
so doesn't seem like it would hurt to try removing (but don't think it
would gain you anything either).

Contrary to my believe i did had not searched for rhgb and just assumed it 
would be in the "options=" line.
You were right, after deleting it from the kernel i see dmesg messages and 
slight different UI for password. ESC key switches back and forth. 
Also adding pci=noaer in the kernel line finally removed the messages. 
Thanks.

Looks like you're using UEFI boot instead of grub, so kernel options are
right next door to the Xen options in xen.cfg- look one line down for
"kernel=". :) This is where I see rhgb quiet.
Plymouth.ignore-serial-consoles is new; you might also try removing, but
it could be there for a reason.

There is no rhgb quiet in /boot/efi/EFI/qubes/xen.cfg 
I have been pressing just F2 to unlock Kernel with passphrase for over a 
year now and i was being able to read dmesg messages until XFCE login 
prompt.
Already tried combinations of ctrl-alt-F2, alt-ctrl-Fx, alt-Fx and none 
shows the console.

Today's Kernel update showed some dmesg but way after kernel unlocking and 
right before XFCE Login.

My guess, it might be driver related. I do run qubes with a rx 480 since my 
mobo/cpu does not have intel grafix.

My xen.xfg,
options=loglvl=all dom0_mem=min:1024M dom0_mem=max:4096M iommu=no-igfx ucode
=scan smt=off pci=noaer

(Since install, there have been countless pcieport :00:01.1: AER: 
Corrected error received: :00:01.1 messages with PCIe Bus Error: 
severity=Corrected from the rx 480 and tried to stop displaying them with 
pci=noaer but the option has not helped yet.)

Since i do not exactly remember where i added the pci=noaer, i cannot find 
/etc/default/grub to eddit options, could you be so kind and point as to 
where one modifies kernel options?

Check to make sure "rhgb quiet" didn't get added to your boot options.
Also, isn't it ctrl-alt-F2, or is that only once inside XFCE?

We used to be able to switch to console when typing password or after to 
see messages, now just black screen. 
Pressing F2 again shows GUI.
