[Bug 1885405] [NEW] brightness control sometimes doesn't work after boot
Public bug reported: Brightness control sometimes doesn't work after boot. Doing `sudo apt install --reinstall kscreen`, logging out, and logging back in usually resolves the problem. Booting into Windows, adjusting the brightness, then rebooting back into Kubuntu sometimes resolves the problem.

[Bug 1881213] Re: System hangs at reboot or poweroff. kworker blocked at dp_altmode_work
Switching the ports so that the WD15 dock is connected to the USB-C port closer to the power socket and the display is connected to the other USB-C port fixed the issue. Apple USB-C to HDMI dongle exhibited the same issue when plugged into the same port. When the WD15 was connected to the port closer to the power socket with a display attached, USB devices intermittently disconnected and reconnected. Likely a hardware defect, but @mapengyu could you try to reproduce with the ports switched around? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881213 Title: System hangs at reboot or poweroff. kworker blocked at dp_altmode_work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I still find it weird that no issues occur in Windows. Will try to reproduce with kernel 5.7 and attach dmesg. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881213 Title: System hangs at reboot or poweroff. kworker blocked at dp_altmode_work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Issue still occurs on latest mainline kernel without nvidia proprietary drivers. Attached another picture as logging is shutdown when issue occurs. The attached display is only connected to the dedicated GPU and is not outputted to at all in this configuration. ** Attachment added: "Picture of error message." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881213/+attachment/5378562/+files/DSC_0436.JPG -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881213 Title: System hangs at reboot or poweroff. kworker blocked at dp_altmode_work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1881213] [NEW] System hangs at reboot or poweroff. kworker blocked at dp_altmode_work
Public bug reported: Expected: System reboots/powers off. Actual: System hangs with the plymouth bootsplash with the Kubuntu logo. Pressing escape shows `[OK] Reached target Reboot`. `journalctl -b -1` shows at the end. ``` May 28 16:33:21 jordan-ThinkPad systemd[1]: Shutting down. May 28 16:33:21 jordan-ThinkPad systemd-shutdown[1]: Syncing filesystems and block devices. May 28 16:33:21 jordan-ThinkPad systemd-shutdown[1]: Sending SIGTERM to remaining processes... May 28 16:33:21 jordan-ThinkPad systemd-journald[454]: Journal stopped ``` Letting the computer continue to idle, an error message shows up. I've attached a picture because the error message does not show up in any logs. Possibly a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872817, though the other user did not mention the same symptoms.
