Thanks. This is probably an issue with the default 'nouveau' kernel driver. That causes so many bugs that I would always recommend installing the Nvidia 470 driver instead, as you have.
I would not expect a fix for 'nouveau' any time soon as it is not well supported. But if you are using the Nvidia proprietary driver then that won't affect you. ** Summary changed: - using xorg driver for graphics card prevents suspend + Using nouveau driver for graphics card prevents suspend ** Package changed: xorg-server (Ubuntu) => linux-hwe-5.11 (Ubuntu) ** Changed in: linux-hwe-5.11 (Ubuntu) Status: Incomplete => New ** No longer affects: xserver-xorg-video-nouveau (Ubuntu) ** Tags added: focal -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1946691 Title: Using nouveau driver for graphics card prevents suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.11/+bug/1946691/+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
