A recent update appears to have affected Gnome’s ability to work with Thunderbolt. Prior to an update that happened in the last 2 weeks or so, the Gnome control panel was able to detect & identify my Thunderbolt 3 hardware without problem, but now it shows that TBT is either undetected/unsupported or set incorrectly in BIOS. I haven’t made any changes to the BIOS configuration (it’s set to “Secure” mode, though in troubleshooting I tried “User” and “Legacy” options as well with no effect).
I don’t know which update it is specifically, but the error was present before the 4.20 kernel came out, and I have updated to 4.20 with the error still present. I suspect it’s something to do with Gnome specifically, because /sys/bus/thunderbolt is still present & shows entries, boltd is still running, and usermode console commands tbtadm and boltctl do not throw errors when checking the status. (but if mods feel this belongs in Kernel/Hardware it can be moved there)
Were the compile options changed on the package?
Thanks in advance,
