495.46 Xorg SIGSEGV in Fedora 35, only on MSI MPG Trident3, and only for MATE desktop

I have 4 systems that are maintained with identical *.rpm complements, differing only in hostname, IP + VPN configuration, and fstab, along with systemd services and crontabs per their intended uses. Of these, 2 are perfectly fine with the new 495.46, both HPs, one of which is the HP Omen on which I’m typing (RTX 2070 MQ), the other being an old Envy used mostly for utility work (backup mgmt, VPN hub) (840M), these days not used for anything graphics except having a console session.

X Server 1.21.1.1 crash on startx with nvidia driver 495.46

Your log shows you’re running an old kernel version - have you updated fully? If you added the nvidia* modules to your mkinitcpio.conf you’ll also have to rebuild the initramfs, It will also be worth checking the Arch forum for similar threads.

You could use the 470xx driver till the issue is resolved.
