Reading the initial bug report I see kolAflash said > nomodeset seems to be essential, but not sufficient.
When I added nomodeset to /etc/default/grub ( GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" ) then I can boot without issues, but suspend does not work. To reiterate: * the TTY1 screen is not blank on boot * sleep works * suspend does not work - you get this bug Given this error in syslog: > kernel: [ 0.047848] You have booted with nomodeset. This means your GPU > drivers are DISABLED > kernel: [ 0.047849] Unless you actually understand what nomodeset does, > you should reboot without enabling it > [ 0.047849] Any video related functionality will be severely degraded, and > you may not even be able to suspend the system properly > [ 0.047849] Unless you actually understand what nomodeset does, you should > reboot without enabling it I tried a few things without nomodeset in grub options. In this case: * the default screen, TTY1, (CTRL-ALT-F1) is blank on boot (or has the HP logo only) * sleep works * suspend doesn't seem to work. If you leave the laptop in suspend mode for a long time it does not resume. The screen is black with just a white underscore on it. The last log lines in /var/log/syslog is systemd[1]: Reached target Sleep. systemd[1]: Starting Suspend... systemd-sleep[8263]: Suspending system... kernel: [ 9425.088936] PM: suspend entry (s2idle) As a workaround for the default screen being blank on boot, you can go to TTY2 (CTRL-ALT-F2), log in and run startx from the command prompt. Some tests: * This does not seem to be the same issue as https://bugzilla.kernel.org/show_bug.cgi?id=204241 because the following command works just fine. for i in $(seq 30); do sudo rtcwake -m mem -s 5; sleep 15; done * I've tried adding GRUB_GFXMODE=1920x1080 to /etc/default/grub but that doesn't seem to solve the issue with the screen on TTY1 being blank on boot. The commands pm-hibernate and pm-suspend give the errors in /var/log/syslog > [ 2566.154192] Lockdown: grep: hibernation is restricted; see man > kernel_lockdown.7 and nothing happens The command pm-powersave gives the same "hibernation is restricted" error in /var/log/syslog but the system goes blank and the is unresponsive. ** Bug watch added: Linux Kernel Bug Tracker #204241 https://bugzilla.kernel.org/show_bug.cgi?id=204241 -- 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/1881494 Title: [amdgpu] suspend to ram (standby) crashes amdgpu (Ryzen-7 Vega - HP Envy x360) Status in linux package in Ubuntu: Confirmed Bug description: suspend to ram crashes amdgpu. System is still accessible via SSH after resume from standby. Happens when X is running (gdm/gnome with 3d acceleration) and also when X is stopped. Also the computer never really goes into standby. The cpu fan is running all the time and the power button is fully lighted up. Nevertheless, I need to press CTRL to "wake" it, so I can access it via SSH. I'll attach the dmesg output of several attempts. This is the hardware: https://store.hp.com/GermanyStore/Merch/Product.aspx?id=9YN58EA&opt=ABD&sel=NTB Tested EFI and BIOS bootmode. Please let me know if I can help tracking this down. I'm a software developer (sadly not a kernel developer), so you can ask dirty technical questions ;-) Workaround: Enable hibernation (suspend to disk) and use instead of suspend to ram (standby). What didn't help: Kernel parameters: no_console_suspend nomodeset amdgpu.gpu_recovery=1 init_on_free=0 idle=nowait amd_iommu=flush echo mem > /sys/power/state systemctl start suspend.target echo 0 > /sys/power/pm_async Upgrading kernel from 5.4 to: 5.6.0-1010-oem Using the kernel parameters no_console_suspend nomodeset amdgpu.gpu_recovery=1 init_on_free=0 idle=nowait amd_iommu=flush and doing echo mem > /sys/power/state before suspend made the system acutally not crash. Nevertheless, the cpu fan and the power button stay full on/lighted. So the system doesn't really go to standby either. I'll try to find the minimal combination of kernel parameters. nomodeset seems to be essential, but not sufficient. Without nomodeset the system wakes again for a few seconds, but freezes a moment later (ssh still accessible).
