Yes, exactly correct. You need to remove all vestiges of the previous drivers for a good working reinstall. That is where I goofed Sunday when I just purged and didn't autoremove too when I tried installing the CUDA10 drivers.

Good to hear you are up and running again Kevin.

I am starting to think my issue with the disabled "second monitor" is probably a problem with KDE and how it handles multi monitors..
I am pretty sure my xconf is set correctly.

When i boot the computer, when logging in, I have a splash screen with KDE logo/loading, at this point i have my whole screen, but there is a mirrored smaller screen on the top left corner,
the resolution of this small screen seems to be 640x480 so it match the "X Screen 1" properties. When at the desktop it vanish (i think it is moved to where xconf set it up (right of "screen 1") by default.
And it looks like KDE doesn't like this fake non-connected display much and let me move my cursor into it, even if it is shown as "displays: none" for this screen.

I could try normal Ubuntu, but i am not much of a gnome fan, so i might just leave it like this. Maybe it will get fixed some days..

Can you see 2 monitors in X Server Settings?
You should be able to disable 1 there, or even set them to be clones. So you have only 1 screen.

No, when in the X server display configuration, i only see one screen i can move around..
Same thing if i go into KDE monitor settings, no trace of a second screen.

The only control i have over this "fake" non connected screen is in the nvidia x server display configuration, on the dropdown box
if i select X screen 1, i can select its color depth, and position/offset (absolute, right of, left of... above or below)
I am guessing that is the normal behavior even if nothing is connected.

If i use the --only-one-x-screen, my second gpu vanish from xconf, so coolbits won't be enabled on it

. . Yes that is the Display Active indicator. But I am surprised about a couple of things. Firstly, that while you have two GTX1060-6GB cards nvidia-smi shows two different TDP values. And while the unit with the display active (I am presuming it is the top card) shows the higher TDP and current power consumption it is showing a lower temperature and fan speed than the less 'power hungry' card. Maybe you need to try a different version of the video drivers or maybe your overclocking settings are confusing something?

. . Also if you look in the active processes section you will see that the 'upper' card is running the /runner and /plasma shell functions which are your display. As well the second card is running its own copies of /xorg and /kwin_x11. My rig does not show that, they are only running on the first card.

Probably different manufacturers of the same card.

No it is quite normal, the top one is a factory OC'ed with higher tdp limits, 3fan model with huge heatsink (Asus ROG Strix 1060 6G)
the second one is a normal clocked card with a very tiny heatsink and only a single fan. (EVGA Gaming 1060 6G)
On a cool day the Asus will run 2164mhz and probably more, The 1fan card would probably catch fire at those frequency hehe

I am only using coolbits on the 2nd card to control the fan speed

. . That speaks volumes for the Strix card then eh? I guess there IS an advantage in running the top end version cards for a given GPU.

If it will fit in your case....

Yes i guess there is one, i bought this card used tho, which makes more sense.
Because the price of this card when new was a bit ridiculous considering the price of a 1070 was rather close.

. . What script are you using for your overclocking and can you remember the command line you used to set coolbits?

I am not using a script at the moment to set clocks, i only do it in nvidia-settings yet, i plan to set it all soon, and possibly use keepP2
I've used sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration

(-a is a short for --enable-all-gpus)

What does your xorg.conf have for the entry ServerLayout. It should be the first section in etc/x11/xorg.conf, just post the section here. My three GPU machine has this;

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" 1920 0
    Screen      2  "Screen2" RightOf "Screen1"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "Xinerama" "0"
EndSection

I don't have any trouble with ghost screens, and coolbits works on all 3 GPUs.

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Ill add the xinerama 0 see if helps at all

You might want to add the screen width to screen 1 as you see in mine;

Screen      1  "Screen1" 1920 0

My screen is 1920 wide, so it knows where the screen ends.
