SDDM sometimes crashes on RTX 5060 Ti

NVIDIA Open GPU Kernel Modules Version

575.57.08

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Operating System and Version

Description: Arch Linux

Kernel Release

Linux F*****o 6.14.10-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Wed, 04 Jun 2025 18:52:21 +0000 x86_64 GNU/Linux

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

• I am running on a stable kernel release.

Hardware: GPU

GPU 0: NVIDIA GeForce RTX 5060 Ti (UUID: GPU-00b9f2e0-c5f3-ed8d-d1ea-37ae6bd41851)

Describe the bug

Sometimes, roughly 50% of the time, my computer hangs on boot. After some troubleshooting, I have found out that the SDDM crashes at the following call stack:

#0  0x00007fd38db4ebc5 in ?? () from /usr/lib/libnvidia-glcore.so.575.57.08
#1  0x00007fd38d7d7440 in ?? () from /usr/lib/libnvidia-glcore.so.575.57.08

#9  0x00007fd394f1ee69 in ?? () from /usr/lib/libQt6Core.so.6
#10 0x00007fd3952ca7eb in ?? () from /usr/lib/libc.so.6
#11 0x00007fd39534e18c in ?? () from /usr/lib/libc.so.6

This happens regardless of kernel version, it happened with linux 6.14.10, linux-lts 6.12.32 as well as linux-zen 6.14.10.

I can't verify if it happens with proprietary driver version as it is not compatible with RTX 50 series. I'm aware of workarounds, so I'm not looking for a solution, I would like the issue to be fixed for better stability of the open drivers.

To Reproduce

The issue is very hard to reproduce.

• start the computer
• computer hangs on boot (sometimes)

More Info

No response

Start by reading the attached nvidia-bug-report.log.gz and the stack ending at QRhi::endFrame in Qt6Gui, with attention to the SDDM boot crash on the RTX 5060 Ti. Try to reproduce the intermittent hang across the reported kernel versions and determine whether the open driver is implicated; done means the crash cause is identified and the startup failure is reliably addressed.
