Public bug reported: My system has worked fine for many moons.
Last night, it stopped being able to launch some apps from the launcher. I figured it might need a restart, since I had updated software. Now it will not boot. When I go to grub, I can select the normal kernel or older kernel. It will not matter. Ubuntu splash screen, the 5 dots turn red, then it freezes, then it goes to black screen and says: [ 0.000000] ACPI BIOS Error (bug): Failure looking up [/_SB.PCIO.XHC.RHUB.HS11], AE_NOT_FOUND (20180105/dswload-211) [ 0.000000] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20180105/psobject-252) [ 0.000000] ACPI ERROR: AE_NOT_FOUND, (SSDT:xh_rvp11) while loading table (20180105/tbxfload-228) [ 0.000000] ACPI Error: 1 table load failures, 12 successful (20180105/tbxfload-246) [ 1.536258] nouveau 0000:01:00.0: DRM: Pointer to THDS table invalid /dev/nvme0n1p5 clean, 412566/5767168 files, 21898623/23040283 blocks /dev/nvme0n1p5 clean, 412566/5767168 files, 21898623/23040283 blocks _ And it will be stopped for a while, then the _ cursor will blink as if active/alive, then it will freeze again. I can't do anything from this screen. Though the errors claim to be hardware, my suspicion is software, possibly graphics drivers, because the problem is at the point where you have to turn on the login screen, classic moment where Ubuntu+ graphics drivers fail. Maybe it's gdm, maybe it's the weird Wayland that has to happen at the login screen, I don't know. I'm on the same machine in Windows, experiencing normal behavior, so I believe it's something Ubuntu introduced in the past 24 hours or so that wrecked itself. ** Affects: gnome-sushi (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764459 Title: Ubuntu 18.04 fails to get to login screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-sushi/+bug/1764459/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
