I have been researching the somewhat confused situation regarding NVIDIA driver 620.70.06<\/strong> and Kernel 7.4-rc (now 7.4-rc2<\/strong>), and this was – to say the least – a bit of a muddle..<\/p>\n

One one 7.4-rc system the driver installed and ran successfully with no<\/span><\/strong> patches (see https:\/\/rglinuxtech.com\/?p=3527<\/a> ), but on another it failed to compile with several errors..
\nThis makes no sense, but I can only conclude that the byzantine NVIDIA conftest<\/em><\/strong> series was confused for some reason?
\nI found an (apparently) AI-generated patch and this installed OK on another system but failed on a third..<\/p>\n

I finally found a combination of extracts from several published patches that did work OK on all<\/span> these systems..<\/p>\n
