I did an initrd rebuild and rebooted. Still no change in behaviour.

Still poring over that material, but in the meantime I did at least
manage to get screen output by using "Run on discrete graphics card"
from Gnome.

However a) I want to use KDE, and b) I still haven't managed to get
anything graphically interesting to work, i.e. Windows games via Steam,
which I have been able to run before now on the IGP.

Rebooting with only the AMD card connected to the monitor doesn't work
either. I may have to disable the IGP from the BIOS, but I can't
believe this is the only solution.

It may not be the only solution, but it is probably the least likely to give
problems in the long run across OS versions and driver updates.

Never trust cables and connectors -- you could try swapping HDMI cables.
My experience with switches has been that they work well if you find a
stable
configuration (order in which systems are powered on), but screw up if
something changes (new GPU, OS update, etc.)

Thanks. I was hoping to be able to use both GPUs, which I've been doing
for years with a Windows VM and my old Nvidia card. I'd much prefer
this to dual booting. I haven't yet managed to set up the VM correctly
for the new card, but that's a separate issue.

When I switched from nvidia to amd, many years ago, it was seamless.
But that was older hardware, I didn't have two graphics cards (a builtin
and a discrete), and I am using the radeon driver with an amd cpu, not
an amd card with an intel cpu. Anyway I did a quick search and found
this link that mentions something called prime that seems to do
something like what you want.

Re: Can one rescue a dead SSD?

So, a SSD just dieded on me, the root and home partition was on it. The

If the disk is not visible anymore, no tool can help you, it is
likely a hardware problem.
Have another look at the part of the circuit related to the external power,
that is the place where things can blow up.

Something that may be tried is to have the SSD in a freezer for a few hours
and immediately try it again while still very cold.
The concept is that any half broken soldering may make contact again
thanks to thermal shrinking of the components.
You should be careful to avoid condensation on the cold part, but, well,
there is not much to lose anyway.
Another "fix lost electrical contact" trick is trying different positions
of the drive and a bit of shaking or tapping.

But if something has been damaged, you need a deep investigation of the
hardware, with tools and knowledge that is not available to everyone.
That is, something like this:

(SMD (de)soldering, thermal camera, ...)

Font Error Before a Display of the Grub Boot Menu

2022-11-10 Thread Stephen Morris

Hi,
    When I boot my machine I am getting a font error before the Grub 
Menu is being displayed but is disappearing before I can get a good look 
at it, which may be because of the Grub Boot Theme I am using, which has 
not installed its files into /boot/grub2/themes but has stored them in 
/usr/share/grub, irrespective of the error the grub menus display fine 
with the theme. The error message seems to be referencing 
efi/EFI/fedora/unicode.pf2 as a target but I can't be sure, but the 
theme being used doesn't use that file anyway.
    Is there anywhere I can look to find the message to understand what 
is being objected to?


regards,
Steve

Video record the screen while booting?
