[Bug 1870971] Re: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API
@alexander-s-m: On a fresh install without any workarounds using VLC with the setting "Hardware-accelerated decoding" set to "VDPAU video decoder" (under Tools -> (Simple) Preferences -> Input/Codec) I experience the same low video quality on HDTV (H.264) video channels you are writing about. On UHD (H.265) channels the video is stuck. Setting this to "disabled" in vlc gives good video quality on HD and UHD (the cpu is used intensively though). Oddly on Windows 10 this laptop (Lenovo Ideapad S540-14API) isn't able to show these HD or UHD tv channels without big glitches, no matter which settings, drivers or whatever. Reinstalling didn't help either. At least it seems to work good on Linux. Only other major issue with the laptop so far was the wifi card: Changing this to 01AX709 with an atheros chipset made wifi great again... But back to the topic: I suggest everyone who thinks to be affected by this issue to try to change one line in "/etc/default/grub" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft" and run update-grub afterwards. This seems to have fixed the black screen issue so far (at least I haven't experienced the issue in the last 24 hours) and I didn't notice negative effects of this change.

@katastic Interestingly I've also noticed video output problems in VLC on my Lenovo Ideapad L340-17API. In my case video is present in VLC but quality is quite poor, video looks interlaced even though it is not. Workaround: reconfigure VLC to use another video output module and probably restart VLC.

I have the same issue on a Thinkpad X395: with power plugged in, everything boots fine. However, on battery it will only boot to a black screen once the display manager is started. Plugging the power in, booting up and unplugging the power once the login-screen appears does work, however. Also, using `nomodeset` as kernel option works, but in that case, amdgpu won't be loaded (I assume some generic VESA driver is used in that case). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Apologies, this only occurs from me when I don't have the POWER plugged in. If I am on just battery it will just boot to a black screen, but when plugged in to the charger it boots up just fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am also experiencing this same issue on an Acer Aspire Slim 5. I installed Ubuntu 20.04 server edition and then Mate-desktop on top of that. It seems that I only experience this issue when I do not have ethernet plugged in. With ethernet plugged in the system boots just fine into the window manager. I get the same dmesg output as above. I will try and collect all the relevant information and post it soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1870971] Re: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API
I noticed that after boot with badly initialized GPU idle power consumption is 2-2.5 higher than after normal boots. But this can be fixed by putting laptop to suspend and waking it. Therefore I've extended my workaround from #3 to this: [Service] Type=oneshot ExecCondition=/bin/sh -c "journalctl -fk | grep -Fm1 'amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser'" ExecStart=/usr/bin/echo 'Not good. Restarting display-manager' ExecStart=/usr/bin/systemctl restart display-manager.service ExecStart=/usr/bin/sleep 3 ExecStart=/usr/bin/echo 'Brief suspend to fix power consumption' # Note that mode has to be "mem". "freeze" does not fix power consumption. ExecStart=/usr/sbin/rtcwake --mode mem --seconds 3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ha, that's a great hack and not something you should need to do.

This issue is not 100% reproducible. It happens after 50% of reboots and I can't figure out regularity. But I managed to contrive a workaround! ``` $ cat /etc/systemd/system/fix-graphics-after-boot.service [Unit] Description=Restart display-manager if amdgpu initialization failed After=display-manager.service JobRunningTimeoutSec=30 [Install] WantedBy=graphical.target [Service] Type=oneshot ExecCondition=/usr/bin/dash -c "journalctl -fk | grep -Fm1 'amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser'" ExecStart=/usr/bin/systemctl restart display-manager.service ``` After you've created such file don't forget to enable it: systemctl enable fix-graphics-after-boot.service The idea of this service is to scan kernel logs for 30 seconds after display-manager is started and if there is signs that amdgpu initialization failed then restart display-manager. Works for me! Though adds 15 seconds delay for 50% of boots. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
