I have Bullseye currently installed on my main Linux platform.

When I logged in this morning I got an Out of Range 95.3 kHz/60 kHz error.

Although I have been using Linux since the early days of Slackware and
the Red Hat Mother's day release, I'm strictly  a user. I googled the
problem and got answers that I don't understand. I can boot into the
rescue mode but can go no further.

Suggestions would be much appreciated.

Thanks in advance.

I have Bullseye currently installed on my main Linux platform.

When I logged in this morning I got an Out of Range 95.3 kHz/60 kHz error.

Although I have been using Linux since the early days of Slackware and the Red Hat Mother's day release, I'm strictly  a user. I googled the problem and got answers that I don't understand. I can boot into the rescue mode but can go no further.

Hi Stephen,

It seems strange that you monitor config should "just change" but is this of any use?


Not sure off the top of my head how you persist changes, or whether xrandr is (initially) the correct tool with which to persist changes on your system, but that may give you some clues to check your DE/wm config if nothing else.

Kind regards,
Gareth

What was the system stated immediately before trying? IOW, was it suspended, off,
hibernated, asleep?

It's hard to help much when you tell so little about your current system. Was your
cat sleeping on it when you came to use it? Is it a laptop? How many displays are
attached? What GPU(s)? Which DE or WM? Inxi -GSaz is a good way to provide needed
system info, if you can get logged in successfully somehow, maybe by rebooting, or
Ctrl-Alt-F3 then Alt-F7/F1 cycled a time or three, or cycling the display's power.
Is your video cable loose? Ancient? Is your display ancient, or VGA (analog)? Is
your display under warranty? Maybe it's hinting you'd be wise to upgrade to
Bookworm, or shouldn't be tempted. How old is it?

What version are you running now?

That sounds like something an older monitor could fuss about. Did you
get an indication it had dropped to a lower definition setting? Look at
/var/log/xorg.log.1 or maybe .2 and see what it says. OTOH xorg.log of
any kind is not being generated here. A clue I'm running wayland? Check
and reseat the monitor cables in any event. Otherwise maybe somebody
smarter might know.

So many unanswered questions. :(

> First of all, I don't have a cat, so let's forego any further cattiness.

It really wasn't meant to be humorous. Horizontal configurations with top vents
are attractive to cats napping, leading to hair buildup collecting on components,
overheating, and strange behavior over time.

I see no video outputs on this one:
https://www.newegg.com/asus-m5a97-le-r2-0/p/N82E16813131872

> AMD FX-8320 Eight-Core Processor 3500MHz

No GPU found on that either:

Not likely system RAM has anything to do with an out-of-range display problem.

My then 3 year old LG from 2017 needed new LED strips, shortly after its warranty
expired. LG was Goldstar before its name change.

> All the cables are firmly attached.

When did that happen last, 3 years ago? eBay stuff, or good stuff, and what type?
USB-C to DP? HDMI to HDMI? DVI to HDMI? Any adapters? These come in many flavors.
Is a KVM switch involved?

Is inxi that hard for you to do? No help from rebooting, rebooting in failsafe
mode, or trying a TV instead of your 23?

Out of range is a not infrequent occurrence here, with 11 or so displays shared
among 30+ computers. Reasons are many, including software that works the first
time, then barfs until a restart of X, or the whole PC. Asus' BIOS aren't stellar
performers either. Two of my FM2+ Asus motherboards from 2014 died over a year
ago, leaving me with an AMD PRO A8-8650B on the shelf, and an AMD A10-7850K moved
to an Asrock. Some UEFI BIOS don't like to play nice with their connected
displays. I see more out-of-range from them than from the oldies.

It wouldn't hurt for us to see /var/log/Xorg.0.log in addition to inxi output. If
not found, look for ~/.local/share/xorg/Xorg.0.log.

My previous message suggested

xrandr -q

but this

https://unix.stackexchange.com/questions/651209/how-change-monitors-from-terminal-xrandr-cant-open-display

suggests xrandr expects to run from within a running X session.

If no other displays are available to test the system (or systems available to test the display) do you get the same behaviour from a live cd/usb if you have or can make one?

I was going to ask about logs but Felix has already done so.

Best wishes,
Gareth

Not only that, but there is also the possibility of an exterior
monitor hardware button being accidentally pushed thus triggering a
different setting to become priority. I started a draft response that
I left hanging earlier. Animal related interference was my own first
suggestion, but my mindset was that the culprit might be an energetic
dog.

The other is: What is the screen showing when rescue mode hits "that
stage"? I just had to go through this yesterday k/t something related
to maybe GRUB EFI. Several rescue mode options were almost
understandable, but I opted to just wing it by entering root's
password, instead. That worked, and I'm still typing in that same
session 24 hours later.

Disclaimer is that my issue was not monitor settings so my success is
an apples to orange [anecdote].

If you can run a live CD or USB image, let me suggest a possibility.

Boot to the live system, install arandr. Use it to get your display the
way you want it. arandr will then export a short script (in ~/.screen, I
believe; check the docs). You can then call this from your regular
installation's session manager.

I'm running Debian 11, but I was going to install Debian 12 on another drive in the computer.
As I quered anther person responding to this thread, would that solve the problem or exacerbate it?

Not a good sign. :( Did you turn the TV on, and to the correct input, before
turning on the PC? Some TVs don't like being late to the boot. So do some GPUs.

If network is working, sudo apt install inxi will install it, but because
Bullseye's inxi is a broken antique, better to do the following as root:

cd /usr/local/bin && wget -O inxi smxi.org/inxi && chmod +x inxi
from:
https://smxi.org/docs/inxi-installation.htm#inxi-manual-install

to get the much improved current version. Inxi -Gaz is the best there is for
providing basic graphics troubleshooting info.

> cat for both logs returns:  no such file or directory

Bad sign. I never use Wayland, so can't be sure what if any logging it does that
ordinary people can locate. Xorg should have left an old one in either location if
there is no current one. I think Wayland leaves its stuff in the journal:
<https://www.google.com/search?q=debian+journalctl+wayland>

It's possible to muck up what you have, but if you remove the current drive and
install the different one and Bookworm, it might be your best way forward. If the
installer can't work either, it would be near certain you've acquired a hardware
problem, hopefully easily resolved with a graphics card swap if you can locate one
to try without too much trouble. What to look for might depend on what you have in
there now. NVidia as good at giving people headaches like you have. Intel only
just began (after more than two decades of not) providing discrete graphics cards.
So hopefully you could get hands on a PCIe AMD card made less than 10 years ago to
try.

Simply starting the Bookworm installer, if it starts at all, might say a lot.

Stephen said this happened "when [he] logged in."

Stephen, assuming you actually logged in before the issue occurred, did you log in to a login/display manager such as LightDM or did you log in to a console/CLI prompt and subsequently run startx, whereupon the issue occurred? If the former, either X or Wayland is running at the point of "login screen", isn't it? At some "standard" (high-ish, working) resolution?

"[...] systemd [...] starts all the important system processes
and then starts X11 [...]
which in turn starts a login manager [eg.] LightDM [...]
The login manager starts a session manager [...]
which starts a window manager and usually a menu bar, a desktop [...]"

https://dev.to/jfhbrook/what-s-a-desktop-session-manager-and-why-do-i-want-one-agl

Doesn't this suggest a display configuration problem rather than a hardware issue?

Thanks

LightDM (for example) combines some of this "under one roof/umbrella/[process?]":

"LightDM is a lightweight, cross-desktop display manager. A display manager is a daemon that:

Runs display servers (e.g. X) where necessary.
Runs greeters to allow users to pick which user account and session type to use.
Allows greeters to perform authentication using PAM.
Runs session processes once authentication is complete ..."

but I don't think my point re indication of config issues is affected, is it?

Thanks

Do you have a second machine that can log into the subject machine via

A display configuration problem should not result from shutting down one day and
booting again next day. So, the state of the PC "when logged in" matters. Was it a
fresh boot? A resume from hibernation? Resume from sleep?

Given he got 'into rescue mode', it probably means nomodeset and/or other failsafe
X parameters that could preclude compositing that his DE depends on. It's pretty
important he report what his GPU is. If it's an NVidia, we need to know whether
he's using NVidia's proprietary drivers. It could be that before his last
successful session exit some automatic updates were applied to break a proprietary
driver installation. In that case, booting a prior kernel could be a workaround or
solution.

Indeed, if his words were meant literally, he may have been at a GUI login screen,
but he could have meant login at a shell prompt. From a shell prompt startx or
equivalent causing the black screen means any part of DM or DE or WM or personal
settings could be at fault. If at a GUI screen, he should be able to select some
other session type than his normal one to log into. Other type can mean both
switching between Wayland and Xorg, and/or among other installed DEs or WMs. This
could result in a successful session that might point to a problem with his
personal settings, or the DE or WM session type he normally uses. We need to see
more details about his normal login process, what actually transpired, and what
his normal DE or WM is.

There are multitudes of ways to get a black screen. The more info, the better and
faster a solution might be found.

Now that you have a GPU with outputs other than VGA, find a DVI-to-HDMI or
HDMI-to-HDMI cable and connect that HD5450 to your LG instead of the VGA
cable. If that isn't any better, connect it to a TV's HDMI input to see what
results. I suspect your VGA connection is the root problem, either the cable,
or the VGA connector on your LG. All is good here with Bullseye and HD5450
using VGA connection, HDMI connection, and/or DVI connection:

You might notice that my HD5450 has loaded the modesetting Xorg display driver,
while yours has loaded ati,radeon. You may uninstall xserver-xorg-video-radeon
to allow yours to do the same.
