Graphical corruption and Xorg crash after resume in both Linux 4.19 and 4.20

I am running Linux 4.20-rc6 patched with the PCI_PREF_BASE_UPPER32 quirk from and the Nvidia driver 415.23 on my ASUS GL504GM laptop with a GTX1060. I use PRIME display sink and synchronization to let the nvidia driver access the internal LVDS screen, too. Upon resuming from suspend, the KDE Plasma lockscreen takes a very long time to appear. Upon logging in, KDE complains that the compositor has crashed, and there is graphical corruption such as

When an external display is connected to the HDMI output of the GTX1060, graphical corruption also appears. If I suspend and then resume again, Xorg flat-out crashes (all the opened applications are gone). The attached Xorg.0.log.old is the log from the crashed X server. It ends with an (EE) Backtrace: line, as the X server was apparently unable to even output a stacktrace.

The attached nvidia-bug-report-4.20.log.gz is the output of on my patched 4.20-rc6.

I can also reproduce the issue under the stock Arch Linux 4.19 kernel (setting acpi_osi=! acpi_osi=“Windows 2009” to work around PCIe issues makes no difference). The report right after the Xorg crash is attached as nvidia-bug-report-4.19.log.gz

Upon switching batch to the X session from the virtual terminal that I used to create the bug reports, I noticed the Xorg screen was all black save for the mouse pointer. I switched back to the vt and immediately created another bug report, attached as nvidia-bug-report-4.19-later As I noticed lots of nvidia-related in the dmesg output, I also attach it as Xorg-crash-dmesg

I am also experiencing similar crashes when I try to boot with an external display attached. In this case, the display manager gets in a “restart loop”, which makes creating a bug report fairly difficult.

As boot and sleep with an external display work in Windows, I’m quite sure that this is not caused by a hardware issue.

Is this an nvidia driver bug? How should I set up my machine so that it works with an external display and resuming?

Now I found out that my X server also crashes without an external monitor connected: upon the first resume after boot, there is graphical corruption, while after the second resume, X crashes and gets into a “restart loop” due to the display manager trying to start it again, but failing. I could not gather an nvidia-bug-report this time due to being unable to switch to a VT. After rebooting the machine, Xorg.0.log.old did not contain any errors. As a temporary workaround, I masked sleep and hibernation in systemd. However, the situation is extremely annoying, and I would much rather prefer if the driver could be fixed.

Something is still fishy after the workaround: when I rebooted, and tried to connect my external monitor, X crashed. After the display manager restarted X, it only displayed a black screen an the cursor (which I could move between displays just fine). There were no errors in Xorg.0.log or dmesg. I attached an nvidia-bug-report from this incident.

Upgraded to 4.20rc7 today. Suspend is still broken (and I did not try HDMI, as Xorg gets into a “restart loop” even without HDMI upon the second suspend-resume cycle. While I could not run on the “restart looping” system, the dmesg from the failed boot (extracted with journalctl -b -1) is very interesting:

Please take a look at the Xorg coredumps:

Upon switching from KDE Plasma to GNOME Shell, I can now sometimes resume multiple times from sleep when no HDMI output is connected without Xorg crashing. It did not solve the problem altogether; however, at least it seems the GNOME compositor relies less on broken functionality of the driver than the Plasma one…

The problem seems to lessen if I set

options nvidia-drm modeset=0

Of course, that disables PRIME synchronization and introduces tearing issues. Please look into this issue, as it makes laptops with HDMI outputs wired to Nvidia GPU useless as “laptops” with Linux. I have to treat my machine as a desktop PC and shut it down every time, not to mention the enormous power drain at idle despite enabling PowerMizer.

On a slightly related note, please also fix PowerMizer on laptops! My GPU is stuck with the highest clock unless I kill my desktop compositor (tested with both KDE Plasma and Gnome) or limit performance with NVreg_RegistryDwords, and many other people report similar issues in these forums. Idling in the lowest PowerMizer setting would make my machine able to be used on battery for several hours despite not having PRIME offload support; however, reaching it with a desktop compositor seems all but impossible.
