Nvidia RTX 2060 not recognised, HDMI not working

I'm at my wits end here. I'm running 19.04 in dualboot(same SSD) with win 10.

On win10 everything is peachy; HDMI and mini display both work perfectly.

Come to Ubuntu 19.04, everything fails. Neither port works(xrandr never pulls up hdmi port as below):

And I've tried everything Google has. All failed. I installed and switched to LightDM, no use. I reinstalled, have gdm3 only running, no use. Any ideas? This is getting super frustrating :(

Connecting the laptop to my dell monitor brings up the message from the monitor: No hdmi signal from your device

ADD: I've switched back from proprietary nvidia-driver-418 to noveau drivers, with no luck either. I opened nvidia settings and am currently running on the iGPU selection.

I ran optirun xrandr and came up with this:

[ 120.658383] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ 120.658412] [ERROR]Aborting because fallback start is disabled

I've switched to running the Nvidia high perf gpu setting(my RTX 2060) in nvidia-settings, restarted but to no avail. Its funny how an OS supported by Amazon has pretty much zero driver/hardware/paid-dev support rofl.

UPDATE:

I just realised my RTX 2060 isnt even recognised in the software&updates-Additional Drivers GUI...

Nvidia Corporation: Unknown

There was a bug posted on installing via .DEB which repository installation solved, so I'd remove the old proprietary drivers first, run sudo add-apt-repository ppa:graphics-drivers/ppa and install the most current drivers available.

Gonna close this question but I have honestly no clue how. Even Nvidia-435 popped up mysteriously. For the record, my secure-boot is already disabled, and I run the storage in AHCI mode(wouldnt be able to install in dualboot otherwise anyway)

What i did was:

1) Do a complete fresh install of ubuntu 19.04

2) Purge all nvidia drivers with sudo apt-get purge nvidia-*

3) Go to Software & Updates ; switch additional drivers to nvidia 435(that automagically appeared in this fresh installation) and my RTX 2060 is still NOT recognised there, shows NVIDIA Corporation: Unknown

4) Open up nvidia settings from terminal

5) Switch to using the intel iGPU (word on the net is using the dedicated Nvidia GPU will block usage of the HDMI/DP port) 6) Reboot

And viola! It works. Sort of. Its all a hit and miss rn. Sometimes the cable works immediately. Most times I gotta pull it out and reinsert the thing like a monkey ten times before the monitor registers. If i used the miniDP port previously then the HDMI port doesnt register for 9/10 tries. And vice versa. WHY. The ports honestly feel like a timebomb rn. I got no clue when if ever, this fix will fail and I'll have to switch laptops again.

But, temps and battery life have definitely greatly improved. I get close to the same 6 hours on my laptop here as with Windows 10. User experience is pretty awesome now save for when I need to dual monitor for work.

But GOD, UBUNTU, FIX YOUR SHIT.
