I'm not in a position to comment about that.  I do have a 35Pre 
installation on Fedora40.  rpms built by Gary's script, and it's working 
well.  But F40 itself looks far from stable at present.  Usually I have 
worked with F n-1, hoping to get the benfit of 6 months shakedown on the 
OS, so maybe the current upgrade rate is just to be expected; seems to 
be several hundred GBs per day...

My biggest trouble is with a dual-boot with Windows 10 box, which 
currently fails to complete booting:  KDE black screen with unresponsive 
cursor.    Both boxes have legacy GT710 nvidia cards, which have vga and 
hdmi outputs, using nouveau. That's mainly for control and editing.  I 
don't really need vdpau/nvdec, and 'real' watching is usually by leanfront.

I'm not recording at present on the bootable F40 box, mainly because its 
disks are full.  Enter kubuntu  22.04 PPA (on what was once my 
grandson's hardware) with no nvidia complications  :-)
