SSH terminal randomly gets stuck in Alt/Meta state on RDM Linux 2026.3.0.5
SSH terminal randomly gets stuck in Alt/Meta state on RDM Linux 2026.3.0.5
Environment
OS: Fedora Linux 44
Desktop environment: KDE Plasma
Remote Desktop Manager: 2026.3.0.5
Connection type: SSH
Remote host: Linux
RDM terminal: built-in SSH terminal
While using an SSH session in RDM, the terminal works normally for some time and then suddenly starts behaving as if the Alt/Meta key is still pressed.
Normal keyboard input is replaced by sequences such as:
^[i
^[n
^[d
^[j
^[s
^[kFor example, typing normal characters results in ESC + character being sent to the remote shell.
At the same time, Ctrl+C stops working correctly. The remote shell continues to behave abnormally and pressing Ctrl+C does not interrupt the current input/process as expected.
Workaround
Pressing the Alt key once immediately restores normal keyboard input.
After pressing Alt, the SSH terminal works normally again without reconnecting the session.
Reproduction / observed behavior
Open an SSH session in RDM.
Use the terminal normally.
After some time, the keyboard input may become corrupted.
The terminal starts receiving ESC + character sequences (^[x).
Ctrl+C no longer works correctly.
Pressing Alt once immediately fixes the problem.
This seems to indicate that RDM is incorrectly retaining or restoring the Alt/Meta modifier state in the SSH terminal.
Please investigate whether this is a regression or a known issue in the 2026.3.x terminal/keyboard handling on Linux.

Same for me. If you click another connection then back to the one you want, that seems to fix it for me. Your solution of the ALT key also fixes it. Thank you!
Hello,
Thank you for contacting us on this matter!
We have provided all the information to our QA Team to see if they can reproduce the issue. Once we have more information, we will let you know.
In the meantime, If you have any further questions, please don't hesitate to let us know.

This is confirmed to be resolved for me in 2026.3.1.1 Thanks!!
Just installed. Yes, now it's working. Thanks u @Maxim Robert and team.
I take it back. It's partially fixed. It doesn't do it with SSH any longer, but if I flip back and forth from a Windows RDP session, the arrow keys in command prompt and powershell don't function until I press the ALT key again.
Hello,
Thank you for the additional information. I’ve reached out to our development team and shared the remaining issue affecting the arrow keys in Windows RDP sessions. We’ll let you know as soon as we have an update.

Hello,
Our development team has confirmed that the remaining issue affecting the arrow keys in Windows RDP sessions is being treated as a separate bug.
I’ll keep you informed as soon as we have further updates.

Hello,
Thank you for your patience.
Our QA team has reproduced the remaining issue with the arrow keys in Windows RDP sessions.
It is tracked as its own bug, and the fix has passed our internal testing.
The fix will be included in Remote Desktop Manager Linux 2026.3.2.0, which should be released in the next few days.
Until then, pressing the Alt key once after you return to the RDP tab restores normal input.
Switching to another tab and back also works.
Once 2026.3.2.0 is out, please update and let us know if the issue is resolved.
Best regards,
Carl Marien

Once you have installed the update, could you please test it in your environment and confirm that everything now works as expected? If the issue persists or if you notice anything unusual related to the same original problem, just reply to this message with a few details, and we will be glad to look into it further.
Thank you for your collaboration.

Its odd. I am on 2026.3.2.1 I connected to an RDP on Windows Server '25 and then alt-tabbed to another window. I switched back with alt-tab again, and in powershell I was able to type asfgh but not D for some reason. I right clicked start, went to run, and I was able to type D there. I flipped back to the powershell window and D was working. Odd. So I closed out of RDM and started over, and it did the same thing again. Third time, it was fine and I haven't been able to reproduce it.
So I guess its fixed?
Hello,
Thank you for testing and for the detailed feedback.
We’re glad to hear that 2026.3.2.1 resolves the issue. The fix covers both the original Alt/Meta problem in SSH sessions and the arrow-key problem in Windows RDP sessions after switching tabs.
We’ll consider this topic resolved. Thank you both for your patience and collaboration.
Best regards,
