Linux - downgrade to version 15.27.3

15.29.4 appears to have resolved the issue. TV on Mint now connects to Windows as expected.

Sorry for reactivating this topic but I fear I have to report the exact same problem on LinuxMint 20.3, but the latest version still does not cure it. Any Teamviewer version higher than 15.21.4 starts fine, but does not register any mouse interaction at all.

Tested with Teamviewer 15.29.4 (both .deb and the tar file and the host), 15.25.5 (.deb file only) and, 15.21.4 (.deb file and host) and 15.16.8 (again, .deb file only). I uninstalled the previous version in all cases but also treid to install 15.21.4 first and then upgrade to 15.29.4. A "sudo apt –fix-missing update" does not find any missing dependencies.

I'm Afraid I had the same problem on version 15.29.4. I'm running Linux Mint 20.2 as follows:

-Version-

Kernel      : Linux 5.4.0-110-generic (x86_64)

Version      : #124-Ubuntu SMP Thu Apr 14 19:46:19 UTC 2022

C Library      : GNU C Library / (Ubuntu GLIBC 2.31-0ubuntu9.9) 2.31

Distribution      : Linux Mint 20.2

I had version 15.29.4 installed and it wasn't working as a client in a way very similar to what Gigi183 described. After much investigation, I decided to go back to 15.27.3. Not easy, as I couldn't find a way of downloading the earlier version. Eventually, I googled "teamviewer_15.27.3_amd64.deb" and downloaded it from a mirror (VERY DANGEROUS). I uninstalled and purged the later version and nervously installed the earlier. It worked fine.

I then upgraded back to version 15.29.4 and IT STILL WORKED! There is certainly an issue here but I suspect a clean re-install would have sorted the problem.

I am usually never joining on any forums however

Could not connect from Android device and Windows and other Linux machines to that specific 15.30.3. Either it would get stuck on "Initialising session" from Windows to Linux and just drop the connection without any error message and from Android to Linux it would just hang forever until it times out. No difference weather using TV ID, VPN IP or LAN IP. Any other machines were working properly.

Therefore that sudo apt install teamviewer=15.18.4 solved the critical problem!

Upgrade to 15.18.4 successfully solves the problem that the latest defective downgrade 15.30.3 introduced (or as it appears even few versions before).

Best regards

TV 15.30.3 wouldn't let me connect to a  Linux Mint 20.3 Una if the screen was locked. Downgrading to 15.18.4 worked - thanks

@.Carol.fg. This is good news, thank you very much! If there is anything I can help you your developers with please tell me, I will gladly run any test software and send you its output if that helps.

Dears I have to say that I had a similar issue with 15.33.7.

the UI is just DEAD.

after searching a while I realize that that was my WACOM Tablet (intuos pro pth-451 in my case) . When using the tablet and clicking with the pen it didn´t work at all.

I found a mouse, and manage then to click on the different part of the interfaces.

If would be also user friendly to have the standard shortkeys like ALT+C for connection, ALT+E for Extra, as the menu was not even accessible at first

I was able to replicate the problem on 2x different PC.

Hope this helps someone.
