I fixed this issue by replacing the 450 Nvidia driver to 455 driver as you mentioned here. Now Steam is working properly and I can play my games again.
For those who wonder how to update the driver, follow these instructions, but before doing mhwd --install pci Your455Family and right after doing pamac remove for each driver installed (including the 450 driver) - which you can list by typing mhwd --listinstalled - you also have to uninstall each of the driver installed (ex. for removing the 450 driver: mhwd --remove pci Your450Family). This last part is not mentioned in the linked tutorial, but I had to do those steps to be able install the 455 driver.
Kernel 5.9 breaks my bluetooth mouse connection. Need to reconnect after each reboot. This only affects my bluetooth mouse but not my bluetooth keyboard.
Itās a knowm issue and apperently affects all bluetooth devices that only support BLE (Bluetooth Low Energy). EDR and LE bluetooth devices are not affected.
Getting my system updated along with VMWare Workstation 16 and Nvidia 455:
Nvidia drivers very easily and cleanly with the Manjaro Settings Manager BUT you need to uninstall cuda for some reason to get it to not error out. Just install it again after updating.
VMWare Workstation 16 needs its modules updated. Best way to do this whenever there is a new kernel is to reinstall it from the AUR. After it has updated the dkms modules reboot and type in a terminal:
modprobe -a vmw_vmci vmmon
this should load the modules needed to keep vmware working. I do this every time I update as well. Just thought I should post this to help anyone who is confused by this as much as I used to be.
Update on 2 computers (KDE plasma) without problem.
However I cannot use linux59 because linux59-nvidia-390xx is not in the repositories. Will it come later?
Both my Wifi and my ethernet stop working after updating to 5.9. (I am now in 5.8 again because I know it works). The vote/poll said to post about my problems so I am.
That is expected as CUDA or other tools may be build against your currently installed drivers version so changing drivers version requires you first remove this programs relying on a specific version, then you reinstall them for the new driver version.
Question about that directory permission difference of dhpcd: Isnāt there a way to repackage this package with an additional post_upgrade or post_transaction hook which chmods the directory with the correct permissions?
Anyone else having lag issues with KDE? It just feels so much slower and more laggy after 455, and I canāt downgrade because that breaks Steam. God I wish I hadnāt updatedā¦
