Local X server crashing?

[aave]

Hello,

I have my whole desktop session crashed when I try to connect to remote NoMachine servers

The GPU is some new intel iris, the laptop is new Thinkbook Gen 4 16p.

[Fri Oct 20 19:11:13 2023] traps: nxplayer.bin[13372] general protection fault ip:7f1cd64674a6 sp:7ffed0b29200 error:0 in libc-2.31.so[7f1cd644e000+159000]

On my laptop these are the versions:

ii  nomachine                                                   8.9.1-1                                    amd64        Fast and secure remote access system

00:02.0 VGA compatible controller: Intel Corporation Device 46a8 (rev 0c)
No LSB modules are available.
Distributor ID:    Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:    11
Codename:    bullseye

I have tried to reinstall the NoMachine package, didn’t help. I have tried to stop the NX on the remote server to get a new clear desktop, in that case it gets to the point where it asks me do you want to start a new session? If I say yes the X on my notebook crashes restarts again.

Any ideas what to try? I use latest custom kernel 6.5.7 it is the same with the stock vmlinuz-6.1.18 kernel.

Hi,

first thing to try is disabling hardware decoding on the computer you are connecting from.

Exit the Player and then go to $HOME/.nx/config/player.cfg on your machine, edit the “Enable hardware accelerated decoding” key and set the appropriate value as indicated to ‘disabled’. More about this is in following article:  https://kb.nomachine.com/AR07U01202

If that doesn’t help, send us:

– nxplayer logs
– journalctl output (sudo journalctl -x |grep -i gdm)
– /var/log/Xorg.0.log.old (cat /var/log/Xorg.0.log)
– if there is a core file from nxplayer, extract the backtrace

Instructions are how to extract player logs are available in section 2. How to Collect Client Logs from Users’ Devices of the following article: https://kb.nomachine.com/DT07S00244. That article also outlines how to extract the backtrace (section 4).
