I had a similar problem, but I could ssh into the machine,
otherwise I would say it was locked. My problem was the video
driver (NVIDIA card). I fixed it by installing the manufacture
driver.
Dear all,
I'm running Debian 10 with the recent updates using a RT Kernel to run a Machine using Linuxcnc. I face the problem that Debian "hangs" i.e. becomes completely unresponsive. This includes Keyboard, Mouse and also the SysReq + REISUB does no longer work. The system does not really "crash" i.e. I keep seeing X. Usually X and keyboard freeze a bit before the mouse pointer also stops to move.
I have the feeling that this only occurs when there is a realtime task running but I cannot say that for sure.
Not sure if pastebins are appreciated here:Output of dmesg: https://pastebin.com/zgh6Cw84Xorg.0.log:https://pastebin.com/eNJCLTWf/var/log/messages https://pastebin.com/EbJh4qYY
I did spot anything obvious in the logs
This PC was used for a couple of years for Machine control running a Realtime Kernel on Debian 7
I'm a bit clueless at this point and would appreciate hints what to check for.
Thanks,Malte
