BUG: After longer time of not running PC it fails to load login screen

[MaCroX95]

I'm not sure if I'm writing this issue in the correct section so I'd like to ask someone to replace it if it needs to be anywhere else :)

There is this strange bug that happens every morning when I turn the PC on. It loads the system but fails to show the login screen, it only happens once and after the reboot it starts working correctly as it should. It seems that the bug occurs every time the computer has not been running for a longer period of time for example overnight.
Hardware:
MSI MS-7528 Motherboard
Intel Core 2 Duo E8500
Nvidia 9500GT (Nouveau driver)
4GB DDR2 (800MHz) RAM
HDD: WD Black 320GB (7200rpm)

Software:
Solus 3, Budgie (updated to latest)
Kernel 4.14.15-48 (current) x86_64

Solus is the first distribution that has the mentioned problem, so I'd gladly help in solving it, let me know if there are any logs that I can send to the development team so they can look into the issue. I wrote some basic hardware info above.
