Hi,
I have seen this post for a Nvidia video card and not sure if is the same problem as myself. It's about the only thing I haven't tried to get my displays working.
viewtopic.php?f=23&t=14555
I'll try to explain the details of my venture as best as possible.
I purchased a new Gigabyte G5 KD laptop (can be found here: https://www.gigabyte.com/ca/Laptop/G5-- ... 1th-Gen#kf and the specs here: https://www.gigabyte.com/ca/Laptop/G5-- ... -Gen/sp#sp) and installed a new SSD drive with Mageia 8. It's now dual booting with Windows and Mageia 8. I can't stand Windows which is the reason I installed Mageia.
The laptop has dual video cards, one Intel and the other Nvidia. Here are the specs for the cards - can also be found with more detail on the Gigabyte site - link above:
-Intel® UHD Graphics
-NVIDIA® GeForce RTX™ 3060 Laptop GPU 6GB GDDR6
Boost Clock 1425 MHz, Maximum Graphics Power 105 W
NVIDIA Max-Q Technologies:
Dynamic Boost 2.0, Resizable BAR, and Optimus™ Technology.
There are 3 out video ports so the laptop is able to have 3 displays plus the laptop screen for a total of 4 displays. This is the main reason I bought this laptop.
Here are the video ports:
1x DisplayPort 1.4 Type-C over USB 3.2 Gen 2 - plugged to a 43 inch UHD television - Type c to HDMI
1x HDMI 2.0 (with HDCP) - plugged in a regular 24 inch monitor - working like a charm by default
1x mini DP 1.2 - not plugged in yet but will be plugged in once I get my problem solved
I have been trying to configure the display port 1.4 that is hooked up to my 43" UHD television. I have been using the graphical interface to try and set it up and have failed many times. The closest that I have been to getting anything to work is using the following steps:
step 1 - Launch graphical interface tool from MCC
step 1 - select Nvidia option GeForce 420 to GeForce 630
step 2 - select option configure all heads independently
step 3 - install Nvidia propriatary drivers
step 4 - only select option Automatically start the graphical interface (Xorg) upon booting
Once all is installed I reboot and I can see the cauldron loading screen on all 3 displays (laptop, 24 inch monitor and the television) but then I get stopped with the errors "training failed" X 3 and "core notifier timeout" X 2.
At this point I can get to the command line but don't really know what to do from here. What I do is use the Mageia 8 cd to do an "update" to get back to default settings. Sometimes it works like a charm and I'm back to normal but sometimes I get locked out of my user account and need to delete 3 .Xautority files in my profile to get back in. I use root user to do this.
I then proceed to uninstall all Nvidia drivers and then reboot. At this point it looks like I'm back to normal and everything seems to work fine.
So far no luck with a multitude of settings.
I'm wondering if anyone could give me a pointer on how to get my setup working. I have very little experience in setting up displays in Linux and just enough experience to get by using the OS.
If anything is needed such as log files or screen shots please let me know and I'll get whatever is needed.
Thanks for anyone who has a look.
Cheers
