coolbits blank screen at startup, if delete xorg.conf, all back to normal

[mzaloon]

Hello guys!

please help me identify the issue causing the problem

I run Mint 19, and i have 2 GPUs, 1080Ti (main, connected to monitor), and a secondary 1070.
all runs ok, but i need do some overclocking, and needs control fan manually, for this i run the command:

sudo nvidia-xconfig -a --cool-bits=31
this results creating a /etc/X11/xorg.conf

so, i reboot, and ...
after reboot i have no video, just blank screen, and no error messages... so i CRTL+ALT+F1 to tty1, and delete xorg.conf with RM command.... and reboot...

so, after deleting xorg.conf, system boots normally again, working perfect...
this is very weird... i really need xorg.conf to use coolbits, but system not works when xorg.cong is in place... any ideas????


NOTE: the coolbits set is not causing the problem, because i already tested with no coolbits on xorg.conf, and blank screen back...
currently driver is 415.18, but 396 and 410 same issue..

please help!

this is my Work machine, i can't broke system, so, i need help to do coolbits work and change my fan speed for rendering on GPU at low temperatures.

HELP!

sudo nvidia-xconfig
then open it: /etc/x11/xorg.conf
and add this to the section of your graphics:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 9800 GT"
Option "ModeValidation" "AllowNonEdidModes"
Option "TripleBuffer" "1"
Option "Coolbits" "4"
EndSection

Option "Coolbits" "4"

where did you get =31 from?

from here:
https://bitcointalk.org/index.php?topic=1712831.0

and on Mint 18 worked, but when upgrade system to 19 (clean install), no work anymore.. the blank screen thing.

[trytip]

i been using :
Option "TripleBuffer" "1"
Option "Coolbits" "4"
since ubuntu 11.10 which works for my nvidia-340. try it with coolbits 4

[mzaloon]

just tried, nothing.. blank screen...

as i said, just the fact of xorg.conf exist on /etc/X11 make my linux not boot in UI.

this is very weird.

[mzaloon]

when i run: sudo nvidia-xconfig -a

the result on terminal is:

Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found
New X configuration file written to '/etc/X11/xorg.conf'


some tips??


the resulting xorg content is:

any ideas why system not boot on UI? even on "empty" xorg.conf?

why do you have 2 ? is one integrated into motherboard?

[mzaloon]

take a look, i do a video right now showing the weird behaviour...

https://www.youtube.com/watch?v=5Y1NRiYCPt4&t=13s

[trytip]

when you get to the blank screen before you remove xorg.conf and after you log in do startx

[mzaloon]

doing startx before removing xorg, just go to blank screen...

look:
https://www.youtube.com/watch?v=IDyT6uf7tfI

this image can contain a clue???
https://photos.app.goo.gl/nXNT2NUwB1C1besq8


maybe missing some on system?
xorg needs be installed? (if not already... its a mint 19 normal clean install)

[mzaloon]

i'm going crazy...

[trytip]

what kernels are you booting with? dkms status

[mzaloon]

4.18.16
but even default one, the same problem...

i use 4.18 because my wacom is model "One by WACOM", only supported after 4.16... so default 4.15 (actual for mint) is not for me.
installed via ukuu kernel update utility

[trytip]

what does this do in Terminal

Code: Select all

dkms status

[mzaloon]

nvidia, 415.18, 4.18.16-041816-generic, x86_64: installed

[Hoser Rob]

GPU over/underclocking is not supported by Nvidia (or AMD I think) because voltage tuning isn't, and it likely isn';t going to be, ever. I'd fiorget about this idea if I were you.

no, both are boards.
used for GPU rendering with RedShift Renderer.
