I should have mentioned that the screen blank flashes or flickering, is not the only symptom since there it comes with very little but noticeable "adjustments" of the screen brightness, and then, from time to time, the blinks. This all occurs specially when the PC is being used or working, seems less frequent at idle. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1940285 Title: [Teclast F7] Laptop screen flickering on kernels above 5.4 (not included) Status in linux package in Ubuntu: Incomplete Bug description: Recently, I installed Ubuntu 21.04 on my laptop and I was having the same problem I had like with others distros such as Fedora; for some reason, the screen just ramdonly and briefly turns off, (more like a flickering) and it also "autoregulates" a the brightness, just a little bit down and then a little bit up.

Please try editing /etc/default/grub and change: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0" and then run: sudo update-grub and reboot. If that has not fixed the problem then we will provide additional instructions for how to test other kernels. ** Summary changed: - Laptop screen flickering on kernels above 5.4 (not included) + [Teclast F7] Laptop screen flickering on kernels above 5.4 (not included) ** Tags added: hirsute -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1940285 Title: [Teclast F7] Laptop screen flickering on kernels above 5.4 (not included) Status in linux package in Ubuntu: Incomplete Bug description: Recently, I installed Ubuntu 21.04 on my laptop and I was having the same problem I had like with others distros such as Fedora; for some reason, the screen just ramdonly and briefly turns off, (more like a flickering) and it also "autoregulates" a the brightness, just a little bit down and then a little bit up.
