<Solved>Screen Blacking out after several minutes after installing alongside Windows 10

[d8sconz]

I installed LM (18.3 Sylvia) on a spare drive after moving windows to an SSD. It works perfectly. The only slight annoyance was that I couldn't get to the grub menu without hitting the 'f12' key at boot, so I decided to also install Mint on the SSD alongside windows to automatically default to the grub screen. Everything works fine except my screen goes black after several minutes on this new install (alongside windows). I am currently working from the original installation on the HD partition and everything is fine (no black screen). Result of inxi -Fxz (for the SSD install) =

It says that graphics drivers "FAILED(?)" I'm new to Linux (relatively) and not sure where to go from here. Does this mean that the drivers are faulty/not there? And if so, why does the screen work OK for some time before blacking out? Any help appreciated.

Thanks

It might help to run inxi -Fxz again from the working HD system to compare with the SSD install.

I'm guessing your monitor is connected to the add-on nVidia GeForce GTX 750 Ti, and not the integrated Intel GPU.

Different Kernel and/or not installing the nVidia driver from Driver Manager are possible leads to check. GPU temp at 81C seems a little high, but I also see all the CPU cores are running near max. Was that inxi on the SSD install run at idle, or is there some process running to cause the high CPU activity?

If you're not using the integrated Intel graphics, you might Disable that feature in BIOS. Look in the Peripherals menu in BIOS settings for "Intel Processor Graphics".

With a Gigabyte MB, it is very important to immediately enter BIOS setup and "Load Optimize Defaults" and Save-Exit after you update/flash BIOS. After you do that, reboot, and then (again) go to BIOS setup and adjust settings, as needed. I've seen some very odd behavior on boards if you don't following that procedure.

For future reference, this line tells you what is trying to run-
Display Server: X.Org 1.18.4 drivers: (unloaded: fbdev,vesa) FAILED: intel,nouveau

Which means the nvidia card is not being loaded, and the intel is failing to load. I did not include the resolution, assuming you know what your max reso is and not to go over it.

Your: GLX Renderer: NV117. tells mine you have nvidia drivers installed, but no successful boot to identify the card correctly.

So to confirm Clix: odds are your bios is set to cpu graphics, and the display is trying to run off Nvidia. Disabling cpu graphics should let the Nvidia drivers load properly. and to also confirm CLix, you may need a different kernal as well.



Here is how mine looks. Its shows what your nvidia stuff should kind of look like when properly loaded.

Thanks for all your help.

ClixTrix - old nVidia driver was the problem, although I can't recall needing to change them on the HD install. But then I was like a kid in a candy store and was playing with all sorts of settings I should have taken a note of. I don't quite understand however, how the screen worked at all. The screen is plugged into the nVidia card with bad drivers and the cpu graphics didn't load so I'm curious how I got any kind of screen at all - and why black out after a period of a few minutes? I've disabled cpu graphics in bios and startup is even faster now (i'm back on the SSD). Also, thanks for the heads-up on temperatures. My motherboard was recently replaced by two dodgy guys on motorbikes (no kidding) and I remain to be convinced that it was even necessary. The upshot is that the air inlet fan on the case has nowhere to plug into now and I wondered if that would affect the temps. From what you say, it does so I'll have to figure out a solution for that one as well. For now I can actually see what I'm doing and I can retire the HD installation. Thanks for your help.
