fridobox First of all, you need to accept that "your laptop graphics only work with kernel 5" is likely a false statement. Whatever issue you have with kernel 6.6 is likely solvable, please open an issue on our issue tracker:
https://github.com/getsolus/packages/issues/new/choose
Frankly we do not have the bandwidth to maintain more kernels than we already do. We can only maintain two kernel versions, current and lts, and at some point we need to update lts to a newer version and that time is now. We're not downgrading back to 5.15 now, please work with us to help us figure out your issue so that you can continue to be on a kernel supported on Solus.
For now, if you really need to continue to use 5.15 (hopefully only while you're helping us debug your issue) then you can switch to the old kernel in GRUB or in systemd-boot by mashing the down key while you boot. You should see the old kernel still present and can switch to it. Note that since we're not going to be updating the 5.15 kernel at some point you'll be exposing yourself to security vulnerabilities by continuing to use that old kernel and that Solus could break with it as any time as we're not testing Solus against that kernel anymore and we will not be fixing compatibility issues that are only present in 5.15 and not 6.6.
