[Kernel-packages] [Bug 1870971] Re: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API
@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. This command made video quality in VLC normal for me: sed -i 's/.*vout=.*/vout=gles2/' ~/.config/vlc/vlcrc -- 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/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API Status in linux package in Ubuntu: Confirmed Bug description: Freshly installed Xubuntu 20.04 shows black screen instead of login screen upon boot on Lenovo Ideapad L340-17API.

[Kernel-packages] [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.

[Kernel-packages] [Bug 1870971] Re: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API
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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API Status in linux package in Ubuntu: Confirmed Bug description: Freshly installed Xubuntu 20.04 shows black screen instead of login screen upon boot on Lenovo Ideapad L340-17API.
