Kernel 6.2 have issues on webcam, need to use an older one as default

in flag

Some weeks ago my Ubuntu installation on my Dell Latitude E7470 received kernel 6.2 (now 6.2.0-31-generic), but this update raises issue on my webcam. I can do meetings as usual but the image is flickering continuously because, I suppose, is continuing adjust brightness to react to environmental light. I try to boot with an older kernel, my case 5.19 and the issue disappeared. Given the facts that:

  • kernel 6.2 has some issue on the topic
  • kernel 5.19 seems discontinued

I need to find a way to use, as default so it should be something reboot/update proof, a previous kernel version that should be at this time 5.15.0-60-generic still installed.

Thanks for any advice

Run the command `lsusb`. Edit your question to include the line of that output that is your camera. Show us that complete line.

You've not mentioned what release you're using, but Ubuntu 22.04 LTS has two supported kernel stacks (*I'm skipping OEM stacks for simplicity here*), being 5.15 or the GA kernel stack, & HWE which is now 6.2 (*it was 5.19 not long back; 6.2 from 23.04 & 5.19 from 22.10*) thus if your release is 22.04 or *jammy*, then 5.15 is a supported kernel. You didn't mention your release though (*6.2 is the kernel from 23.04, which is where 22.04 gets it*)

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.
