How to? Digitally connect to projector with Ubuntu 18.04 or 20.04?

2

I have two laptops which are exhibiting the same behavior (which is to say no behavior at all) when I attach either to my projector. I have two available cable paths for testing, both yielding the same results.

Lenovo w530 (mini-display port --> DVI) Ubuntu 18.04

Lenovo x220 (display port --> DVI) Ubuntu 20.04

I have tried two different DVI cables (with an appropriate set of adapters for each set-up). This is the same cable used to test the external monitors (well, one of the two is but neither work with the projector so I didn't haul the 15' garden hose of a cable in to test it as well).

If I attach any external monitor, I get the expected behavior: There is a brief flicker and the second monitor appears in the Displays settings area. By contrast, if I attach either laptop to my projector nothing happens to either. There is no flicker (of recognition); there is no change in Displays; xrandr shows no changes. Google was fruitless.

What do I need to do to make this work?

I was able to confirm this is a digital connection issue. I cobbled together and tested a VGA solution and it behaved just like the monitor connections have.

EDIT:

I have included output from sudo journalctl --follow:

Output from two separate laptops attempting to connect to an Optoma projector via a DVI cable.

This first one is running Ubuntu 18.04. I added the gap in the middle when I connected the cable with a mini-display port adapter. (There is likely superfluous output at the end as I was checking the projector and not looking at the output directly.):

Also, this first laptop is running a special driver (the second laptop is not). Per Software and Updates:

This device is using an alternative driver.

Cannot connect to wireless projector (Samsung LED TV)

2

I installed Ubuntu on my new laptop and I need to connect it to a Samsung LED TV.

When I was in Windows 10 I was able to connect to my TV by just pressing the combination of Windows+K. Then it would automatically connect to it. I can't connect now.

Solution to perspectivicly warp the whole screen?

2

Is there a way to perspectively warp the whole screen, so i can correct a image which is displayed on a projection screen from a strange angle?

Background is, we have a play and i would like to project background screens. Because i want to use a variety of Media Types and also would like to remote control the whole thing, the easiest way would be to simply warp the whole screen instead of using projection mapping or something.

To be clear, there is just one rectangular surface i need to transform the image on.

getting HP laptop to work with projector

3

I have an HP Pavilion dm4-2033cl laptop (specs here) and am running ubuntu 14.04 LTS. I'm a professor and I need to be able to use my laptop on projectors in different classrooms (all apparently different models!) but so far it isn't going well.

I find that when I plug in to the projector by the HDMI cable, my resolution drops down usually to 640x480, a bit bigger in one classroom. When I plug in by the VGA cable, the resolution is fine but the option to "mirror displays" is grayed out and I have to treat the projector as a second screen (i.e. turn my back to the students to give my demo).

I think this may be a clue to the problem: When I go to Settings -> Details, the "Graphics" card is described as "Intel(r) Sandybridge Mobile". However, I know from HP that I have an Intel HD Graphics 3000 card. Does this mean I have the wrong driver, and could that plausibly be the problem? If so, how would I fix it?

This is the video card described in the output of lspci -v:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
