re: a) > perhaps also laptops with only nvidia cards if those exist I don't think those exist; you typically want an iGPU for the low power consumption. But, if they did exist they'd be rare enough for us to be unable to find anyone to verify the test plan. In any case a laptop would trace all the same code-paths a desktop would, as there's no special handling of laptops (anymore).
re: b) > is the SRU only changing the default session, i.e., for users who have never logged in before, or have never made a choice. No, changing the default will also affect users who have already logged in, regardless of whether they ever made a choice or not. > What if I have an affected system, but have opted in to use Wayland, will this SRU change my choice and revert that to Xorg? There are four possible situations here: 1. Laptop originally defaulted to Xorg, then the kernel 6.8 update changed the default to Wayland -> the fix will revert you back to Xorg 2. Laptop originally defaulted to Xorg, then you opted-in-to Wayland, then the kernel 6.8 update changed the default to Wayland but you didn't notice as you already were using Wayland: -> the fix will revert you back to Xorg 3. Laptop originally defaulted to Wayland (as far as we know that has only happened if installing with 22.04.5 or 24.04 which have kernel 6.8) -> the fix will revert you back to Xorg 4. Laptop is unaffected, it originally defaulted to Xorg, updating to kernel 6.8 did not matter, and is still defaulting to Xorg -> the fix will not change the default, so you will keep your preference While all cases 1~3 change the current behavior, I only see case n.2 as changing the user *choice*. But we cannot do anything about it now because on an affected system there is no indication of whether the user is currently on Wayland because they chose to or because it is the default. re: e) We are choosing to default to Xorg mainly because all certified laptops shipped with Xorg. And while the OEM team might be open to re-evaluating Wayland in an existing LTS, that should only happen after testing (and possibly re-certifying?) and not because of a sudden bug. ==================== I will later edit the bug description addressing your points. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/2080498 Title: Default session type changed from Xorg to Wayland in some installs of 22.04 on Nvidia hybrids since kernel 6.8 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/2080498/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
