CommonUser pretty sure that message is normal, I see the same thing.

what about running dmesg | grep -i blue ?

Also, was bluetooth working for you before the sync?

      davidjharder when i run dmesg | grep -i blue it is resulting

      for the problem i'm not remember if it occurred from when i using solus 4.3 before, but i sure that after i reinstalling to solus 4.4 it is the bluetooth is not working. is my hardware not supported ? but when i using opensuse timbleweed it is working fine.

          First: Thanks for this awesome distro. It is definitely currently one of the greatest desktop distros out there.

          Updated my packages yesterday and one of the packages was the nvidia driver. Now it doesn't start X anymore. Kernel and Nvidia driver are out of the sync. The kernel module has a different version than the nvidia driver package.

          Please correct that asap. Thanx a lot!

            m1h43l you're going to have to be more specific than that, we have multiple Nvidia drivers and they were all rebuilt after the kernel upgrade

                API mismatch: the client has the version 535.86.05, but this kernel module has the version 535.54.03

                          m1h43l Seems like you're booted into the old kernel. The new one is 6.4.8-247. Either your update wasn't complete or something prevents the kernel update from being applied (like a too small ESP partition).

                            eopkg remove linux-current
eopkg install linux-current

                            Now it works. Don't know why.

                              m1h43l probably because the package triggers happened again when you installed the package again. You could have achieved the same effect with sudo usysconf run -f

                                CommonUser Acer specs on that show mediatek mt7921
                                How did we get to lite-on are you using external adapter or replaced mt7921?

                                On that note another user had mediatek issues we could not seem to resolve dont know if he ever got it working.
                                I cant find much about lite-on.

                                    Axios nope, i didn't using any external bluetooth adapter or replacing it.

                                        CommonUser Do from terminal sudo LC_ALL=en-US.UTF8 lspci -vnn
                                        and see what it says for network controller.

                                                CommonUser Ok it is mediatek not sure bluetooth is going to work like I said earlier
                                                Unless somebody knows something I dont.
                                                There was a long thread we had about this dont remb the name tho.
                                                The users wifi worked fine but his bluetooth wasnt your error code looks similiar to his and it crashed
                                                at about the same point if memory is right.
                                                Sorry I wasnt of more help we were hopeing kernal updates would fix it.

                                                On a note I looked your computer up and that module is easy to replace I would recommend the intel
                                                If bluetooth is needed its supported good.

                                                    Axios aaahh okay got it, thankyou for the information it is helpful, if you not pointed out about that i have no idea what's going on. For the usage of bluetooth it is not that urgent so maybe i can wait till next kernel update available.

                                                    But one thing i got curious, when i using opensuse tumbleweed i am using the kernel 6.4.3-current if i'm not mistake, and i can use the bluetooth as usual.

                                                        CommonUser Alright I think I see the issue. Kernel needs some more enablement around that, I'll get it added to the next Solus kernel. Can you please run the following command on your system?

                                                        eopkg info linux-current

                                                        And then respond with the output. I can give you early access to the next kernel when I build it. I also need to know whether or not you're using secure boot.

                                                            ReillyBrogan for the secure boot yes i enable the secure boot from the bios when i'm installing solus 4.4, running eopkg info linux-current resulting
