Ubuntu install not booting normally after live boot ejected

[yancek]

The fact that you were not able to boot any usb with anything other than ventoy is irrelevant to the problem. I'm not sure what you are talking about when you say grub2 does not boot only grub. Ubuntu has exclusively been using Grub2 since 2009. There is no grub on Ubuntu, meaning the old Grub Legacy so that is irrelevant also.

Why are you running the usb and the Try Ubuntu option when you indicated previously you could boot Ubuntu from the hard drive using the Advanced option, recovery and resume method. Do that and run the commands suggested by oldfred. When you run the commands, watch the screen for messages particularly any error messages and let use know what you see if anything.

Hi yancek, sorry, I brought up the grub thing because in Ventoy there are the 2 options, one works the other does not.

I am NOT running the "try ubuntu" option, If I do that, my screen washes out, in other words the output display on the screen is useless, I am giving context so that you are able to understand what works and what does not.

I did watch the screen, problem is there is so much going on that I do not know what to look for and it all passes by before I can comprehend what is being said.

Sorry for any inconvenience or irritation caused by my ineptness....

Regards

No problem. If I were irritated I wouldn't waste my time responding. I was just trying to be clear and although I've never used Ventoy, I do know that some Linux systems refer to Grub and Grub2 separately and have directories named Grub2 as well as Grub and use commands containing grub2 not just grub so that's now clear.

In one of your recent posts (19) you were referencing using the Try option on the usb and apparently that was an explanation of what you had done previously. The suggestions by oldfred in his earlier posts were to consecutively run the commands and see if you got any output or if on rebooting, you would be able to see the screen properly. I don't have any suggestions about fixing the graphics but I do know that NVidia cards often pose problems for Linux users but they're great for windows.

To clarify things, were you able to boot the installed Ubuntu by going to Advanced and recovery options? Were you able to consecutively run the commands suggested by oldfred in the earlier post? My understanding is that you completed the install of Ubuntu to the hard drive and were able to create a user during that process. The Ubuntu install won't complete unless the user does this so you did do this, correct?

If you run a command and a lot of text scrolls by and you are returned to the prompt from which you started, that usually means success. If there are errors/warnings you will generally see the word warning or error near the end of any output, often in uppercase letters. Following that will be information relating to the error which is often not understandable to most of use. That is the information being sought. So, as oldfred asked, do you see and warning/error message when going through this process? If so, what warning/error. If possible, write down the error/warning message or take a photo with a smart phone if available and post that information here.

Hi Yancek,

Sorry for the delayed reply I sm currently on leave now so not able to look into the request now, I will be back home in about a week and will then resume the requested tasks.

I just though (in connection with ventoy) that I might be gacing other challenges in connection with loading an install, as I am unable to boot with any of the other mediums, I understand the nvidia cards are an issue, have known that from past dealings with Linux, but never ran into the issue this severally, I am in Africa so we do not have a very wide choice when it comes to vga cards and the prices are close to what a motor vehicle costs 2nd hand so pretty damned expencive, I have this card because I do some cad design and a lot of video editing. I hope I am able to get Ubuntu up snd running though, windows is not doing me any favours by charging what they do every 4 odd years for OS's....

Agsin, thank you, MafoEllfen and oldfred for your help, it is greatly appreciated.

Regards

NVIDIA cards are great, if you are using windows but have historically been problematic with Linux. The link below discusses using NVidia d on Ubuntu which might be useful to bookmark.

I've been using high-end graphics such as NVidia, AMD, & Intel with Unix and Linux since 2005. Albeit, that's when Alan Coopersmith taught me things about using them with Xorg (in OpenSolaris)... I didn't know at the time who he was, or his 'place' in Xorg... I just knew (then) that he expanded my previous knowledge about XServer, and how it could work. I've been passing-that-forward for over 22 years.

For Linux... Let's just agree to say that they (drivers for high-end GPU's) can be challenging for a new user. Because they are non-free drivers, there are things that need to be done for those. A process. A new user needs to learn how those things work, and how to maintain them, to use them.

That process is a lot easier than it used to be in 2011, when I wrote the "Graphics Resolution" Sticky, but most everything there is still relevant on what to look for, how to diagnose the Linux Graphics Layer, and what to do to correct things. That is "why" that sticky is still there.

A lot of those things are automated and made easier now, but it is not a perfect world yet. Things still happen and go wrong. Education is still the key to this. New 'things' are in place, but the basic concepts are still the same.
