I started having this issue on my HP Probook with 5.13.0.27, the problem happens when I lock my laptop (does NOT restore - flickering screen - had to hard reboot).

Here is what I got on my hw:

*-display
description: VGA compatible controller product: Renoir vendor: Advanced Micro Devices, Inc. [AMD/ATI] physical id: 0 bus info: pci@0000:05:00.0 version: c4 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi msix vga_controller bus_master cap_list configuration: driver=amdgpu latency=0 resources: irq:46 memory:d0000000-dfffffff memory:e0000000-e01fffff ioport:2000(size=256) memory:e0600000-e067ffff

Please let me know if you have any ideas.

Please provide your OS & release details; you mention Ubuntu and a kernel version (a kernel that is used by multiple releases), so some options that may exist for you may also not exist; depending on details you've not yet provided (ie. what product/release are you using?) *You mention hard reset; did a clean SysRq reset command work to resolve? or are using using a product/release where that's not possible? Could you switch to text terminal & explore etc*

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.
