I have an integrated Intel graphics card and a discrete Nvidia card plugged on a PCI port. I’ve been using a three monitor setup by using the Nvidia card as my main card (two outputs), and using the Intel card (one output) via Reverse PRIME.
My computer was rebooted a few days ago (it had been on for a long period), and suddenly the setup broke. I cannot enable reverse prime again:
$ xrandr --setprovideroutputsource modesetting NVIDIA-0 X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 139 (RANDR) Minor opcode of failed request: 35 (RRSetProviderOutputSource) Value in failed request: 0x249 Serial number of failed request: 16 Current serial number in output stream: 17
Maybe some package upgrade broke this setup, but I wonder which one. I have tried several kernel versions (5.4.24, 5.4.63, 4.19.98) and the last two driver versions (340.107, 340.108) without success.
Find attached the nvidia report: nvidia-bug-report.log.gz (78.3 KB).
