I have been using a company computer running Ubuntu 22.04. There are frequent and unexplained problems, like segmentation faults, stack errors, files disappearing, computer freezing or not booting, or turning off immediately after I turn it on. I don’t know what to do. The IT staff came to my office to check the computer and said “it was all good.” I am not allowed to boot from a USB stick or enter BIOS or open the case. I ran a command line memory check several times with no errors. There is an NVIDIA card, but it’s running X.org and usually headless. I mostly set up tasks via SSH.
What would you do?
They should be able to put memtest on the boot partition and then break to an EFI shell on boot and Ioad it manually.
There will be a bit of swearing and googling required but it’s doable in a way that doesn’t mess with the current boot arrangement.
