Solving old monitor woes

I decided to install Ubuntu to replace Windows on an old system of mine. So far, I am having troubles with the display. This display was also an inconvenience on Windows 10, and so the same root cause could be generating issues here.

In general, Ubuntu is not detecting my display. I can make it work when I boot from the installation Flash Drive, where I had customized the startup by replacing "quiet" with "nomodeset". However, I do not know how to make the display work when I boot from the new installation of Ubuntu on the hard drive.

Still, Linux should be customizable in some way to make it work, but I don't know how. That's my question. Please be aware that I know almost nothing about Linux.

*I should mention that this is an Acer monitor from 2011, and I use an adapter to go from HDMI to DVI to the computer.

**Thank you both for the comments. Here is the output of that command:

The HDMI-DVI adapter shouldn't be a problem but thanks for adding details. First of all please understand what `nomodeset` does, it forces a generic VESA video mode compatible with pretty much everything and overrides any graphical driver. Because of that additional driver functions like connections to external monitors may not work. The problem is NOT your monitor, the problem is precisely the use of `nomodeset`. Probably you need to install some proprietary drivers (Nvidia) and then **remove** `nomodeset`. Please [edit] the question and add hardware specifications.

To be specific: Please tell us the brand name and model id of the graphics chip/card. You can edit the original question by adding the output of this command: `sudo lshw -C display`; indent each line of the output 4 spaces to render it as `code` (makes it easier for us to read).

Thanks especially for the instructions! I am not sure what my hard disk booting is using. I tried tapping "e" to bring up the same interface to see if it is using `nomodeset` or not, but this did nothing in a hard disk boot.

To possibly clear up some confusing statements that I might have made: The display only works if using `nomodeset`, which I do when I boot from the USB. It will not work if I boot from the hard drive, and I don't know what the hard drive is using, but probably it is not using `nomodeset`.

At least from what I am seeing, this is not the right venue for this question, that is, maybe not a place for absolute beginners like me to ask novice questions. So, where would I go to ask this?

Did you try with the [boot option](http://ubuntuforums.org/showthread.php?t=2230389&p=13370808#post13370808) `nomodeset` in the installed system? It should be possible too, first temporarily via the grub menu, later on permanently according to [this link](https://help.ubuntu.com/community/Grub2/Setup#Configuring_GRUB_2). See also [this Arch Wiki link](https://wiki.archlinux.org/title/AMDGPU) that might be helpful to find a proprietary graphics driver for your card.

If you find this website too difficult, please try at the [Ubuntu Forums](https://ubuntuforums.org), which allows for more discusssions and a stepwise approach to a solution.

Thanks for the info--after spending more time with it, I was able to get something in Radeon working with it, but it was not ideal. I replaced Ubuntu with another type of Linux, and that is working now. I'm guessing that Ubuntu does not easily support that display card.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
