Configuration: Linux Mint Ver: 21.3 ( Virginia )
Arduino IDE: 1.8.19
Since today 2-8-2024 port is grayed out.
Same happened at a system from a former collegue approx. 1 week ago
I looked for the brltty problem, no process like this.

Observe the additional output; you should see a /dev/ttyUSBx.
Although I do not think it's the cause of your problem (it would result in an "access denied message" to my knowledge), did you make yourself a member of the dialout group?
Hallo Sterretje
dmesg -w when I connect the board is like:

Good morning,
It took me a little more time to do a verification , putty via ttyUSB0 with a loopback wire is working. Arduino-Ide ver 2.3.2 Linux 64 bit.Appimage is also "working" ( sees the port ) . Arduino IDE ver 2 is not an option for me, there are too many differences for the STM32 compared with ver 1.8.19
When referring to Ver 2, are you referring to the installation from Mint's package manager? If so, that thing is antique; don't be fooled by the 2.something in the name.
Or are you referring to an older version of IDE 2.x (e.g. 2.0.1)?
Hallo Sterretje
The IDE ver 2.X or as I referred before the: Arduino-Ide ver 2.3.2 Linux 64 bit.Appimage is the current AppImage 64 bits ( X86-64 ) as obtained from the website https://www.arduino.cc/en/software.
Not refering to Mint Package manager, I know that the releases there may be old.
Have you checked your groups? Normally your user must be a member of the dialout group.
Open a terminal and type "groups" and enter. Is dialout listed there?
If not:
sudo usermod -a -G dialout username
Huh. I am not experiencing a similar problem.
Using MacOS 10.13 (old) and a portable install of Arduino IDE 1.8.13, the port menu has become grayed-out.
This is in spite of the fact that there are still multiple serial ports listed in /dev/tty*,
and a portable install of 1.8.19 on the same machine at the same time still sees all of the ports...
Very weird.
Adding: renaming the old portable install and copying over a new version, the new version also works fine...
I would also be interested to know. The platform developers know, but as is seems to be standard practice for developers they didn't have the respect for the users to spend a minute to communicate that information. So the rest of us are either left to wonder, or else waste hours digging though low quality commits to figure it out.
I guess we just have to be grateful that they even made the effort to document the loss of Arduino IDE 1.x compatibility.
That is correct. We do now have a "pluggable discovery" system, where platforms are able to contribute their own tools for discovering ports of novel protocols. However, that was added in Arduino IDE 2.x so, if anything, we would expect the ports list to only be affected by installation of a specific platform when using Arduino IDE 2.x (though of course a 3rd party discovery tool should not affect the discovery of serial ports since serial discovery is built-in and always running regardless of which platforms are installed).
It appears that the Ports do not disappear until after the IDE is reloaded.
(which is weird, since the ST boards are "available" immediately after installing the board package.)
I've also re-interpreted ST's lack of interest in debugging it as "it's an Arduino IDE bug and they're not going to fix 1.8.x anyway" rather than "our latest board package is only supported in IDE 2.x, so we don't care if 1.8 is broken."
