@Kai-Heng Feng: When I posted that I was comparing my Tumbleweed kernel which is running 5.8 with the two ubuntu installs . . . that seemed to break when they bounced up to 5.8. The two ubuntu distros are now running something like 5.4 . . . because I unchecked the "pre-release packages" box . . . .
Checking the "pre-release packages" box brought in the 5.8 kernel into the two ubuntu installs, but caused problems with video . . . . I assumed at the time that it was "the kernel" . . . . There are quite a few system reports posted in this thread, but I don't think any of them show the system when it was using the 5.8 kernel . . . because nothing could be seen . . . . Today I'm back in my Tumbleweed install, that system is running the 5.8 kernel . . . and it is working well . . . much faster than the 5.4 kernels that my ubuntu installs are . . . etc. -- 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/1890211 Title: 5.8 kernel appears to break video in two groovy installs Status in linux package in Ubuntu: Confirmed Bug description: Ran apt to update/upgrade in both of my groovy distros, Lubuntu & U-MATE 20.10 . . . on reboot not only was my grub list broken in both cases but seemingly the update to the new 5.8.0-12 kernel shows splash logo, but "logs" to a black screen. Display power light is "on" but screen is black. I repeated this several times in both systems . . . having to boot using SG2 to another distro to repair grub . . . then after I did that I got to grub list and went to "advanced options" and rolled back to the prior 5.4.0-42 kernel . . . and GUI is operational. I believe in TW I am running 5.7 kernel and that system has video. I have an Nvidia card and I'm using "nouveau" as my driver.
