[SOLVED] New 20.04 install, hard crashed twice within a few minutes of booting

[suplero]

I haven't experienced this before, but it could be because of my system:

Fresh install on new (refurbished) drive, with windows partition. Windows installed and runs fine.
Installed Kubuntu 20.04 normal install with all the updates and 3rd party packages.

Running Kub20.04, every 10-15seconds the mouse would pause for a second or so,
I only installed a few widgets at this point: simple monitor, cpu monitor, thermal monitor, network monitor, and the redshift widget.
After installing these is when I noticed the mouse pausing. It could be because of these, or just noticeable.
thermal monitor had a gpu monitor - using the nouveau device?

installed smartmontools, did smartctl on /dev/sda and all was fine. Ran short test, and passed and zero problems with the drive.
Decided to install some packages, started konsole, sudo apt install kicad, and the system locked up
Nothing on the desktop responded, no numlock change, no tty1, etc. Drive light is on solid, but starts to flicker then goes out.
Hard power down, reboot.

Reboots normally, back into KDE.
I am suspicious about the nouveau driver, and have a GT-710 installed. System settings driver manager finds it, and I click install.
Download goes fine, 8% into the driver install, the mouse stops moving, and hard drive light is on solid.
When the drive light goes off, I hard power down.

booted into another linux with the 20.04 drive as a second drive, and looked around a bit
here is what was in /var/log/syslog:

I don't know what this means, but it seems like this was the last thing the kernel was doing.

This is the first time I've had a Kubuntu crash in a long time with this hardware. Currently running 16.04 on the primary drive and that has never crashed.

Any help would be appreciated. If I can't install the nvidia binary drivers, will nouveau ever work?
thanks

Have you tried an Nvidia driver?

I don't have a GT710, but I do have:

inxi -Gxxxx
Graphics:  Card-1: Intel HD Graphics 530 bus-ID: 00:02.0 chip-ID: 8086:1912
          Card-2: NVIDIA GF108 [GeForce GT 730] bus-ID: 01:00.0 chip-ID: 10de:0f02
          Display Server: x11 (X.Org 1.20.5 ) drivers: modesetting,nvidia (unloaded: fbdev,vesa,nouveau)
          Resolution: 1600x900@60.00hz
          OpenGL: renderer: GeForce GT 730/PCIe/SSE2 version: 4.6.0 NVIDIA 390.132 Direct Render: Yes

Under 18.04.4 I needed to change my Nvidia driver, as there were difficulties showing up. I ended up adding this:

deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu/ bionic main

which allowed the install of 390.132 that was recommended at the Nvidia site. The graphics drivers is a PPA, which I usually avoid, but Nvidia is a good resource and in this case it worked.

I have an Nvidia GT650M which uses the 390 driver. It has been faultless.
I found two possible solutions while browsing the web, both in this single link. The first solution was to replace the GPU. The second solution was software involved:

Thanks GreyGeek,

I went a different route, and I haven't determined if there is a performance penalty or software conflict.

I found an online guide to installing both ubuntu and kubuntu desktops on the same system, with sddm and tasksel, and that allows for changing from ubuntu to kubuntu on boot/login.
https://vitux.com/how-to-install-the...ntu-18-04-lts/

This let me use the ubuntu installer, which allows me to select several different partitions for encryption at install without crashing, and then I followed the guide to install kubuntu-desktop on top of that.

Ubuntu installed with the nvidia driver, rather than initially going with the nouveau driver, and that seemed to fix the mouse stutter and it also hasn't crashed.

I kind of think that it was the temp monitor widget with the nouveau temperature selected that caused the problem, and with the nvidia driver installed, the temp monitor can just use that.

Glad you got it sorted out.
