Latitude 7430 does not detect intel graphics card (choking)

ru flag

This week I installed ubuntu 22.10 in my latitude 7430 which is supported ubuntu hardware but, it does not load the intel driver for my graphics card AND the video "chokes/freezes" every few seconds. What can I do?

It shows driver=i915, so Intel driver is loaded. Is issue then something else?

you can try adding nomodeset to grub. By the way, this is the worse laptop ever for Linux. HDMI and USB-C video outputs are not working, display brightness adjustment is not working. Display rotation (even manual) if you want to use the tablet is not working. The only thing that I got working is the fingerprint.

@oldfred so the problem is that the i915 doesn't work well. I get glitches in my screen every now and then and even playing videos is troublesome; videos just stop/break randomly.

@maxadamo adding nomodeset disables brightness control which is a no go for me (bad eyesight), so had to remove it. Trying out acpi_osi=linux

Do not know if this applies to you or not. Often fixes for newest chips also help several generations back, also. I have motherboard with i5-12400 and have no issues with Kubuntu 22.04. I have booted with 22.10 but not really used it. My chip is not the top end model and shows video as Device: Mesa Intel(R) Graphics (ADL-S GT1) (0x4692) Version: 22.0.5 Typically very newest hardware takes a while for Linux kernel & drivers to catch up.

I believe i had the same issue as you.

I think this is related to

If you use Ubuntu 22.04 and do not install any updates, so that you are using the Kernel 5.15 kernel, you will be ok, everything seems to be working normally for me, except the touch screen which I am not sure my laptop even supports or not.

I sit in a Tesla and translated this thread with Ai:

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.
