Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Hello Robert, you could try disabling extensions in gnome, or gnome-shell, or mutter; I have heard those are a common cause of stability issues.

Thanks

[Daniel van Vugt (vanvugt)]

The attachment 'GsettingsChanges.txt' suggests there are no extensions enabled.

[Daniel van Vugt (vanvugt)]

Please:

1. Wait until the problem happens again.

2. Immediately after restarting, run:

   journalctl -b-1 > prevboot.txt

   and attach the file 'prevboot.txt'.

Hmm just noticed these replies thank you will try all of this only happened once since then.

[Robert Chilewski (chilewskirbuu)]

prevboot.txt

[Daniel van Vugt (vanvugt)]

Thanks. Unfortunately I can't see an explanation there right now.

If you have any crash files in /var/crash then please let us know and follow https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

Otherwise this sounds like some kind of kernel crash.

Np. I have a whole slew of different problems now with a new AMD card so ya lol :) this isnt the right card either and i have no drivers for it will post another boot text later with new card its literally crashing every 5 mins now gonna Rage a bit here meow Thank you for understanding lol :)

Gnome COntrol Center

[Robert Chilewski (chilewskirbuu)]

Add: I had to disable Temp max restart in win10 to get this motherboard to work work correctly it was doing the same thing with random restarts until i disabled that which is not good for the normal user but i monitor my temps closely and do shutdowns(side note)
:looking into what could be causing the same issues with this i disable da few bios suspend sleep features as of this moment no restart but ill troubleshoot some more!

[Robert Chilewski (chilewskirbuu)]

Add; I also purged previous nvidia drivers/ xorg,conf files as of now with all of this no restarts.

[Daniel van Vugt (vanvugt)]

Please report crash files using the 'ubuntu-bug' command only and don't attach them to bugs. But good news: crashes in gnome-control-center are not relevant here since that won't crash the whole system.

[Daniel van Vugt (vanvugt)]

Is comment #12 meant to say the bug is gone?

Please only send us prevboot log files when the bug has actually happened. On the first reboot after it.

[Robert Chilewski (chilewskirbuu)]

Ah sorry for the belated Response, I have no idea its even worse now with AMD card but i dont have screen tree so i supose ther eis always some balance in life lol :). It onyl restarts when im not using it which doesnt really bother me i drno theamd drivers dont work right , working on some amd support might go back to ubuntu 20 seemed more stable thanks.

[Robert Chilewski (chilewskirbuu)]

Can i close this somehow using a newer Ubuntu kernel now Will try and figure out ty :)

[Robert Chilewski (chilewskirbuu)]

It was never an Actual System Bug persay But i think i have narrowed this Random Crash to GPU driver/ Resolution HZ settings. Thank you! So technically the drivers i were using persay manufacturer dont work very well i have made my own custom drivers and functioning quite well very stable so far ty! I UNDERSTAND!
