Centos Dual monitors not working version 430.40 elrepo

Having a hard time getting both monitors to work at the same time. If I run nvidia-xconfig --enable-all-gpus then the hdmi port works but then it doesn’t display on the latop. I believe its a setting in this file just not sure how or what to set it to.

startfresh install then ran this /***********
so at this point I was actually able to get into the machine… After that I followed these steps…

yum install $(nvidia-detect)
yum bumblebee

I have done a bunch of these and can’t seem to get it right… Any suggestions please let me know again. I believe its just the config file but how do I figure out whats what?

This is an Optimus notebook so it requires special setup.
Please use the rpmfusion drivers, those have some packaged the required config, see this:

Thank you. How do I find the .run file? I mean it should be somethingXXX.run correct? Where would I find that at?


I went to both pages and I did not see a .run - or instructions to uninstall a .run file if that helps any.

Skip that part, the user in that thread used the nvidia web installer. Instead, uninstall the elrepo packages and use the ones from rpmfusion instead.

Sorry I misread that. ha it is a Approved Repositorie

Still only getting one display :(

I didn’t do anything under special notes - https://rpmfusion.org/Howto/NVIDIA#Current_GeForce.2FQuadro.2FTesla

is something else required?

Now if I run any of the nvidia-configs like
–base-mosaic I can’t even get the hdmi to work at all. With elrepo I could… I am not sure that helps any… Not sure where to go from here.

I tried https://rpmfusion.org/Howto/Optimus nothing on that… :(

Trying cuda now. Cross your fingers. sudo dnf install xorg-x11-drv-nvidia-cuda

UPDATE - nothing… I think I may just go back to elrepo as at least I could get one screen or the other to work. Honestly not sure what to do or try now.

Tried uninstalling and reinstalling everything. Also tried a fresh install centos too… I am sure I am missing something silly.

don’t create an xorg.conf at random. Please delete it, reboot, then run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

thank you. here is your log. For the record I only created it after everything else failed then deleted it.
nvidia-bug-report.log.gz (69.3 KB)

Looks like the packages for Centos don’t fully set this up yet. Please use (c/p) the xorg.conf and create the .desktop files for Gnome like here: https://devtalk.nvidia.com/default/topic/1022670/linux/official-driver-384-59-with-geforce-1050m-doesn-t-work-on-opensuse-tumbleweed-kde/post/5203910/#5203910

thanks. I will try in a week or too. I may just go back to elrepo then. I figure that should work fine with the other config. Right? any thoughts? At least with elrepo I can get other monitors and it seems like more stuff is supported too.
