Crash on Wayland with Nouveau driver

Support

I’m having a problem with Kicksecure 18. Using Wayland with the Nouveau driver seems to cause my system to crash. My system logs show the following errors:





localhost kernel: nouveau 0000:01:00.0: gsp: mmu fault queued
localhost kernel: nouveau 0000:01:00.0: gsp: rc engn:00000001 chid:16 type:31 scope:1 part:233
localhost kernel: nouveau 0000:01:00.0: fifo:c00000:0002:0010:[labwc[2244]] errored - disabling channel
localhost kernel: nouveau 0000:01:00.0: labwc[2244]: channel 16 killed

If I blacklist Nouveau and use Pixman instead, the system becomes very slow. Kicksecure 17 worked fine with this hardware configuration.

Is it possible to run Kicksecure 18 on my desktop with this setup, or is there a known workaround for this issue? Additionally, is it possible to switch from Wayland to X11 to avoid this problem? I’m open to any suggestions.

I assume you followed these instructions to use Pixman:

If so, there’s not much that can be done. Falling back to Pixman software rendering is the primary workaround for this issue. The other one is to install the proprietary NVIDIA drivers:

Alternatively, if your system has both NVIDIA and Intel GPUs, you may be able to blacklist the Nouveau kernel module entirely to force the use of the iGPU, or you may be able to disable the NVIDIA GPU in your system’s BIOS.

Not currently supported by the default desktop configuration. However, you may be able to install Debian 13 with X11, then distribution-morph to Kicksecure, installing the kicksecure-baremetal-cli package. See:

Thank you for your message. I have already followed your Pixman and NVIDIA instructions. I think my best option is to install Kicksecure within Debian.
