If I might add to this issue; I also have an XPS15, GTX 1650 and Ubuntu and POP!Os both trigger the issue (kernel 5.3.0-7625-generic). I also have deep as mem_sleep and use s2idle.
I have tried the following parameters without succcess: $ sudo kernelstub -a "rcutree.rcu_idle_gp_delay=1 acpi_osi=! acpi_osi='Linux'" $ sudo kernelstub -a "pcie_acpi=off" (In combination and alone) I have also tried forcing persistence with the driver which also did not work. Here is another thread in mint forums https://forums.linuxmint.com/viewtopic.php?p=1728952&sid=d2f654dfa1082400eeea98c9fbf01918#p1728952 The added parameters seems to work for them, but I could not resolve the issue. Nvidia driver is also at the latest version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847937 Title: 'gpu has fallen off the bus' after return from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1847937/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
