I am using Ubuntu 20.04.3 LTS on my HP Spectre X360 with Intel Skylake GT2 [HD Graphics 520] and I am having flickering graphics.

Unlike similar entries that have been reported, my flickering is discontinuous. It sometimes happens showing grey flickering boxes 5-6 times in a minute, and sometimes it does not happen for 2-3 minutes. Overall, it annoys me quite a lot.

I have tried decreasing the refresh rate from 60Hz to lower options, but that didn't work. Updating the drivers or purging Intel graphics didn't work either. I also tried a couple of stuff I saw online regarding /etc/X11/xorg.conf.d/.

I do not have this issue on Windows, therefore it must be Ubuntu-related.

When I set nomodeset on GRUB and update it, flickering disappears, but at the cost of my brightness adjuster and Night Light. As not being able to adjust the brightness is equally bad, I'm only using it as a temporary solution.

Here are the details of my graphics card:

  *-display UNCLAIMED       
       description: VGA compatible controller
       product: Skylake GT2 [HD Graphics 520]

       resources: memory:de000000-deffffff memory:c0000000-cfffffff ioport:f000(size=64) memory:c0000-dffff

Please help me, my hands are tied at this point!

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.
