I have trouble accessing the integrated Nvidia graphics in debian. This is especially anoying as the HDMI plug is not working in the current state.
Intel Graphics are working fine but I want to activate the switch.

Could someone from DELL please look at the acpi dump that I posted on the nvidia form:
bbswitch is not running. switching to pure nvidia graphics would drain the battery a lot faster (and the battery is not very good anyway.)
It could be due to the following warning:
[ 33.401073] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20180810/nsarguments-66)
forget the above message, it is not the actual error
The error is at primus/bumblebee which can not activate the card:
▶ primusrun glxgears /usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input primus: fatal: Bumblebee daemon reported: error: Could not enable discrete graphics card ▶ sudo dmesg |tail -2 [ 1033.751425] bbswitch: enabling discrete graphics [ 1033.751453] pci 0000:01:00.0: Refused to change power state, currently in D3
Here is what NVIDA says about the error:
64-Bit BARs (Base Address Registers)
Starting with native PCI Express GPUs, NVIDIA's GPUs will advertise a 64-bit BAR capability (a Base Address Register stores the location of a PCI I/O region, such as registers or a frame buffer). This means that the GPU's PCI I/O regions (registers and frame buffer) can be placed above the 32-bit address space (the first 4 gigabytes of memory).
The decision of where the BAR is placed is made by the system BIOS at boot time. If the BIOS supports 64-bit BARs, then the NVIDIA PCI I/O regions may be placed above the 32-bit address space. If the BIOS does not support this feature, then our PCI I/O regions will be placed within the 32-bit address space as they have always been.
Unfortunately, some Linux kernels (such as 2.6.11.x) do not understand or support 64-bit BARs. If the BIOS does place any NVIDIA PCI I/O regions above the 32-bit address space, such kernels will reject the BAR and the NVIDIA driver will not work.
The only known workaround is to upgrade to a newer kernel.
what kernel version works with the DELL Precision 5530? - Ubuntu is currently at 5.0, I think.
Problem is probably due to insufficient implementation into the linux kernel. The dmesg log shows:

But I don't know what to do next here.
