Comment 61 for bug 1768976

Ubuntu offered me a security update. It was offering it for a long time and I didn't want to take it, because I didn't wanted to mess it up. But installed all, and it messed it up with kernel 4.15: it couldn't install the 340 nvidia driver I need into the new kernel. It became an endless loop when ran the new kernel version (4.15). I read somewhere that this might be because of video driver. I started the last working linux kernel and activated nouveau. 4.15 kernel started this way, but overheated in a minute and shutted down.

What I did is: started linux in command line mode and blacklisted nouveau, downloaded 340 nvidia from nvidia website and installed it manually (without DKMS, because it didn't work).
Now there is no overheat. Nouveau is the one to blame imo.
