I now have something like: GRUB_CMDLINE_LINUX="pcie_aspm=off nouveau.debug=\"info,PDISP=debug\"" in /etc/default/grub in case you want to know why the pcie_aspm=off it remove the AER corrected errors on PCIE device that my GTX 660 to generate nouveau.debug=info does not give me the information I want, which is the state of the different engines with faulted 1 or faulted 0 after: Apr 10 18:22:59 jenny kernel: nouveau 0000:02:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT] to add more useful info in https://gitlab.freedesktop.org/xorg/driver/xf86-video-nouveau/-/issues/339 nouveau.debug=debug produce so much "crap" that when I "dmesg > somefile" somefile does not have all messages from boot, because there is so much unneeded info, that only unneeded info is in the file. unneeded info looks like this: [ 338.951804] nouveau: DRM-master:00000000:8000900b: fini completed in 7us [ 338.951811] nouveau: DRM-master:00000000:8000900b: destroy children...

Anyway, I need help to build a nouveau.debug= line that would make me achieve my goal... please!
