I got an error message when I ran LinuxCNC two weeks ago."LinuxCNC terminated with an error. When reporting problems, please create a report file and include in your message."Previous Sunday I try LinuxCNC again for my weekend project, ran successfully without any error message.Today Sunday I run LinuxCNC again, but the error message appears again. Thanks for any suggestions.

"Could not connect to display 0.0"
That points to a failing graphic card, but can also be caused by failing power supply and memory module/controller.

Problem solved.
The original display card is VisionTek Radeon 5450 2GB DDR3 (DVI-I, HDMI, VGA) (fanless) $63, bought in Aug 2023. I used a dedicated Noctua 92mm fan to cool it.
Today I buy a new no brand HD7000 display card (HDMI, VGA) (with fan cooling) $13 to replace the old one, no error message when running LinuxCNC now.
Thanks for tommylight much.

Problem seems to be really solved today.
The error message reappeared yesterday. Not only LinuxCNC shows the "Could not connect to display 0.0", but other applications also show the same message as well. I think the problem may be due to some corrupted files in Debian in my old SanDisk 120GB SSD.
Today I replace it will another SSD with the latest LinuxCNC 2.9.3, everything seems ok now.
Sorry VisionTek Radeon display card, it is not your fault.
