I’m trying 5.4 and 5.5 kernels to test a bug fix for the increase in power use while idle for intel integrated video on machines of gen 6 or later (it’s in the official 5.5 kernel rc1, the patch applies cleanly to 5.4.3).
These are not official Ubuntu kernels, although we are invited to do just what I’ve done when testing bug fixes. Other users on the bug list say there are stability problems seen in extended use, so I thought I’d try to use the 5.5 kernel in real life for a while, to see what happens.
But: snap apps don’t launch under either of these kernels. They fail silently. If I can find relevant errors I will add them here.
This manjaro post https://forum.manjaro.org/t/kernel-5-4-snaps-and-flatpaks-not-opening-for-the-most-part/106535 sasys “That is a config issue of the kernel. It is fixed in 5.3 but not yet in 5.4 series.”
Does anyone here know how to fix?
EDIT: By the way, I am copying the kernel config of my most recent ubuntu kernel (5.3) before building the mainline kernel, so therfore I expected to catch any important configuration options.
