I have:
Clevo notebook 32 GB memory (2016)
Processor i7 2.80 GHz
1 “normal “ 512GB disk , 1 Intel ssd disk also 512 GB. NVIDIA Geforce video card.
This happens a few weeks ago:
Suddenly my laptop was froozen. By opstart I saw only a few colorfull stripes on the screen of the notebook, I tought a defect videocard. In bios I see that video was set on DISCRETE I change that in MSHYBRID. Now Now the notebook can also use the videocapability from the CPU. I buy me a Geekom minipc and the old notebook (2016) i wil use for linux play en expirementing with other distro's.
When installing e.g. Kumander 7.1 I have an image on my laptop screen, I can follow the installation procedure on that screen. But after installation, boot up no longer an image on laptop screen and also not on 2nd screen.
Some 'strange' things for a Windows user:
Gparted sees 2 drives wdc and SSD; Dolphin only see the WCD drive.
Looked with Testdisk only recognizes the WCD disk.
CPU-X sees my Nvidia video card (40 degrees open GL version 4.60) and doesn't give any error codes or the like. Graphics test is going well, but I don't know here if he tests the graphics part of the CPU or also the NVIDIA test. Test with spinning prancing horse etc. GLMark2 score = 1459 I don't know how to interpret that score.
My PC setup Geekom mini PC and laptop are connected to Samsung 28" screen via KVM Switch.
A few days earlier I ask on the site of Kumander:

I thought I had a defect Nividia Videocard so I set in de Bios (UEFI) MSHYBRID Now he start up with graphics possibillity from the CPU.In bios was set on DISCRETE. Because of that problem I don’t have any activity on the notebook screen so I use my second screen a 28” (when you are older you need things bigger) screen. For my Kubuntu its perfect.
On the “Normal disk” I have Kubuntu and on the SSD I will install Kumander. A very nice distro. And expirimented/play with other distro’s
To install I get a very clear menu. But I am not familiar with Linux so I need some help. How to make and partitions? Ext2,3,4 os NTFR, FAT 16 or 32. Need I EFI or is MBR good enouch.
But see the next day:
This morning I try it again and write the steps on paper. Suprise I take the right choise: use the whole disk. But after install I start the notebook and now I get no screen on second screen or the screen of the notebook. GRUB:On start I get a 26 choises of possibibilities I choise the first one, there are The same happens with other distro’s.
Looking with Gparted to the disks IntelSSD: ( I don’t get that in a nice index
Partition: /dev/nvme0 p1; /dev/nvme0 p2; /dev/nvme0 p3
Filesystem: Fat32; ext4; Linuxswap
Size: 512 MiB; 475 GiB; 976 MiB
Used: --; 13 GiB; 0.00 B; Unused: --; 427 GiB; Flags : --; Boot,esp; Swap
Did I sometings wrong?
Thanks in advance.

The first thing you should post here when you are having a problem would be the name of the software you are having the problem with and if it is not common, a link to the site (Komander is something most users never heard of). Is the link below what you are referring to?

https://www.kumander.org/

I'm not sure what you mean by "follow the installation procedure". Are you no longer able to see anything on your screen? Were you following on screen instructions which came with the OS or from an online tutorial.

The information you posted at the bottom of the post is only from the SSD which shows an EFI install on the drive so that should be 'kumander' from what you said and the FAT32 partition shows itis an EFI install and it appears you also have a swap partition and the rest of the drive is the filesystem partition for Kumander. Those are the only partitions needed for an EFI install.

Are you using Grub from Kubuntu or Kumander? Which disk is set to first boot priority in the BIOS firmware. 26 choices is not expected and seems excessive? What is the first choice you selected? Do you see options to boot Kubuntu and Kumander?

It is much easier for members to read command output you post if you use CODE tags. When you are writing a thread, mouse up to the icons at the top of the input box and it will show what their use is. The icon: # is used for code and immediately to the left is another icon which is used for QUOTEs.

I'm not clear on what the problem is. Is it that you cannot boot your Kumander or is it a graphics problem, you don't see a screen in Kumander but do see it in Kubuntu? If this is the case, did you install proprietary NVidia drivers on Kumander?

Thanks for the request.
Kubentu is install on the second disk WCD I wil use the first fisk, the SSD, for playing with several distro's. In GRUB I chose p.e. Kubuntu and without a problem Kubuntu wil start. On my second screen.
When I chose Kumander It seems to start, but after a few minites nothing happens. In the bios I can chose kubuntu. (I just look into the bios I see only kubuntu on p2 WDC. I gone try to install a other distro and looks what happens in the bios. I try to install Kumander again. Now program says : I can't install because of The detected media cannot used for installation purpose.

Hello there, it's good, I have the solution for my problem. I known I read this somewhere before : Nomodeset. But I did known what and special how to do? By try to install opensuse leap I found this site. Carefully read everything on :

https://en.opensuse.org/SDB:Nomodese...tion_Obstacles .

And for my second display set in bios: advance and choose DISCRETE and voila. my 28" display works. I must say, I was at first a little bit suprised that it was standing at DISCRETE the first time and I read that it was normal on MSHYBRID. Now I known why.
Thanks everyone for their help.
