I am trying to get an RTX 2070 running over ThunderBolt in a Sonnet eGFX breakaway box, connected to a ThinkPad P70. The card and the box are working fine on a ThinkPad P52s under Ubuntu 18.04 (NVIDIA driver 418.x, CUDA 10.0), so the problem appears to be specific to the P70.
I do not need graphics on the RTX 2070, just CUDA.
The P70 is also running Ubuntu 18.04 and has a M3000M installed, which is working fine with drivers 410.x and 418.x.
The kernel appears to recognize that the device is connected. Nouveau is blacklisted via /etc/modprobe.d/blacklist-nvidia-nouveau.conf, whose contents are:
blacklist nouveau options nouveau modeset=0
Some output relevant to the RTX 2070 with
lspci -v is:
0a:00.0 VGA compatible controller: NVIDIA Corporation Device 1f07 (rev a1) (prog-if 00 [VGA controller]) Subsystem: eVga.com. Corp. Device 2172 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at b4000000 (32-bit, non-prefetchable) Memory at <unassigned> (64-bit, prefetchable) Memory at a0000000 (64-bit, prefetchable) I/O ports at 2000 [virtual] Expansion ROM at b5080000 [disabled] Capabilities:  Power Management version 3 Capabilities:  MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities:  Express Legacy Endpoint, MSI 00 Capabilities:  Virtual Channel Capabilities:  Latency Tolerance Reporting Capabilities:  L1 PM Substates Capabilities:  Power Budgeting <?> Capabilities:  Advanced Error Reporting Capabilities:  Vendor Specific Information: ID=0001 Rev=1 Len=024 <?> Capabilities:  #19 Capabilities: [bb0] #15 Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia
Though the device is recognized, there is no kernel driver in use.
The output of
lshw -c display is:
*-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:0a:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list configuration: latency=0 resources: memory:b4000000-b4ffffff memory:a0000000-a1ffffff ioport:2000(size=128) memory:b5080000-b50fffff
It appears that the card is being recognized, just not attached to a driver. Any help getting the driver to recognize the external RTX 2070 would be greatly appreciated.
