Well the hardware is working fine as far as I can see.
Can you try to kill the X server over SSH and see if you then get some
screen update?

Can you get me the output of "sudo cat

It sounds like the display stack has crashed, but when the
sound keeps playing the system is most likely still
responsive over network.
Thanks,

What happens is this simple: after a few minutes, about 6 or
so, the entire content of the screen stays still. In some
minor situations only the applications panel of KDE Plasma.
If music is playing it continues playing, so only graphics
are hung. Yet in most cases the power button won't shut down
the computer, as it usually does.
At least this is the case using kwin on x11, and not on
wayland. It only happens on "radeon" and not on Intel or
"radeonhd".

Correct, but a TV is intended for videos only. That's

Interlaced transmits only halve the lines with each
frame, so a 60Hz mode effectively either becomes a 30Hz
mode, halving the vertical resolution or adaptive motion
compensated which the know visual artifacts. Depending
on what the deinterlacing setting on your TV is.
You could just add a progressive 1920x540@60 or
1920x1080@30 mode manually and would have the same
effect with probably better quality. See

for reference.
If you can give us some more information what is
happening when the system freeze we could try to narrow
this down, but we can't spend much time on a very
specific use case in a driver which is in maintenance mode.

No way anyone would prefer that over an interlaced
resolution or a lower resolution. That is, by far, the
worst option.
Just try it on your screen, set it to 24Hz or alike,
and tell me your experience. You can't even tell where
the mouse is going to go.

Hi Alberto,
well a frame rate of 24Hz is perfectly reasonable
for a TV and desktop usage.
This is probably caused by the TVs limited HDMI
bandwidth and a refresh rate of 30/25 Hz for the
interlaced mode isn't much better either.
Regards,
Christian.

The frame-rate at 24Hz is extremely poor for
normal desktop usage.
If the highest resolution, aka 1080p, uses that
refresh rate then the desktop will default to that
frame-rate.
Other progressive modes don't exhibit any issue.

Why do you think so?, the 24Hz resolution
seems to be the native one of the display.

But apart from that if you just connected
your PC to a TV I also wouldn't recommend
using an interlaced resolution in the
first place.
See those resolutions only exists for
backward compatibility with analog hardware.
I think we would just disable those modes
instead of searching for the bug.

I guessed so.
The GPU is a Radeon HD5870, and the
screen is an old Telefunken TV
(TLFK22LEDPVR1).
Since my real display got into repair I
used this TV meanwhile, and to my
surprise it froze the system.

Interlaced resolutions are not used
