I purge all the nvidia drivers and it is fixed now. In fact, there were multiple versions of the drivers installed - 535, 560 and 570 and I have to purge them all. I remember that Ubuntu release upgrade includes a "clean up" step at the end of the upgrade. Does this indicate that this doesn't do a great job and needs to be reviewed?
In addition, https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/2109446 is also fixed by installing the driver using "Addition Drivers". Strange why does nvidia affect the bluetooth? > 6. Optionally, for better performance and a semi-permanent workaround, please consider using a USB-C ended display cable so you avoid the laptop's HDMI port and thus avoid the secondary GPU copy path. My external monitor doesn't have USB-C, thunderbolt interface. I had bad experience with HDMI to USB converter. The connection is not reliable. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/2107684 Title: 25.04 boots up to a black screen, both built-in and external monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/2107684/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
