    After installing Ubuntu 24.04.2 LTS on a new MSI D3052 with an nVidia GPU (3050) in the x4 PCIE slot I get some strange rendering issues. Both are running 8.16.1 and I have had no such problems in the past with my laptops (Windows 7, 8, and 10) and other Linux boxes (Ubuntu going back to 14.04 LTS).

    Monitor connected to DP and hardware acceleration on: Screen is mostly black, but I can see some text and window borders fade in over a minute.

    Monitor connected to DP and hardware acceleration off: Screen is split with the left side black and the right side a compressed desktop. Moving the cursor around via the remote connection shows proper mouse movement, click selection, and keyboard input, but the attached monitor and the remote display do not match up at all.

    Monitor connected to HDMI and hardware acceleration off: Screen is black and I see a tiny cursor that appears to move properly

    Any thoughts on what is causing that and what to try other than hardware acceleration off?

    Hi, did you also try disabling HW decoding on the Player side? That means editing the following key in the player.cfg file option key="Enable hardware accelerated decoding" value="disabled" (see https://kb.nomachine.com/AR07U01202). It’s important to exit the player first and re-open after editing before trying to connect again.

    If that didn’t help either, are you able to send us the full server-side and player-side logs so we can check them? Enable debug on the server side before reproducing the problem. Complete instructions on how to get both server and player logs are available here: https://kb.nomachine.com/DT07S00243
