I removed Trinity during the upgrade to make dependency resolution easier and re-installed it later. All the upgrades were done using the command line method from the installation instructions. After the upgrade was finished I manually scanned for any remaining mga5 packages and removed or upgraded as appropriate, so there shouldn't be any mga5 hangovers on the system in terms of code, although that doesn't exclude the possibility of an issue with a config file. If no other suggestions are forthcoming I'll try a clean install on a spare hard disk with the same hardware, I'll also use this to check it isn't the NFS mounted home causing an issue. > I have 4 TDE on Mageia PCs, but ATM I have no recollection which have upgrades > from 5 to 6 or even have TDE instead of KDE5.

There's no sign of nomodeset in the boot parameters. I'll see if any clues turn up, although I'm tempted to try the spare HD first. For reference, running ksmserver with gdb gives the following, which may or may not be relevant: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff4c196a0 in TQString::TQString(TQString const&) () from /lib64/libtqt-mt.so.3 Thanks again!
