Lately my desktop has been freezing solid and needing to be hard reset [power off/on]. While frozen the cursor will move but nothing else happens. I have tried a number of ways to reset or get information about this condition without a hard reset. I have tried the set of commands which are referred to as “raising the elephant”. This sometimes works without the need to power off the computer. But sometimes it doesn't. I am running Ubuntu 18.04.1.
I have an output from the hwinfo command here. And below is the output from the lshw -c video command.
*-display description: VGA compatible controller product: GK208B [GeForce GT 710] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:27 memory:fd000000-fdffffff memory:f0000000-f7ffffff memory:f8000000-f9ffffff ioport:e000(size=128) memory:c0000-dffff
This latter because I believe that this may be a video driver problem.
What I would like are some suggestions for things, such as commands to try or logs to look at, that can be done after a hard reset to help debug this problem.
