Hi I have Dell Precision 5760 with NV Quadro RTX A3000(6G) card, and it comes with preinstalled Ubuntu 18.04, when I tried to connect to my external Monitor, but it doesn’t work. and it has nvidia-driver-470 driver installed, here are some video card check result: **uname -ra** Linux 5.4.0-89-generic #100~18.04.1-Ubuntu SMP Wed Sep 29 10:59:42 UTC 2021 x86\_64 x86\_64 x86\_64 GNU/Linux **sudo ubuntu-drivers devices:** == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd000024B8sv00001028sd00000A5Ebc03sc00i00 vendor : NVIDIA Corporation driver : nvidia-driver-460-server - distro non-free driver : nvidia-driver-470 - distro non-free recommended driver : nvidia-driver-470-server - distro non-free driver : nvidia-driver-460 - distro non-free driver : xserver-xorg-video-nouveau - distro free builtin == /sys/devices/pci0000:00/0000:00:14.3 == modalias : pci:v00008086d000043F0sv00008086sd00004070bc02sc80i00 vendor : Intel Corporation manual\_install: True driver : backport-iwlwifi-dkms - distro free **glxinfo | grep renderer** GLX\_MESA\_multithread\_makecurrent, GLX\_MESA\_query\_renderer, GLX\_EXT\_visual\_rating, GLX\_MESA\_copy\_sub\_buffer, GLX\_MESA\_query\_renderer, Extended renderer info (GLX\_MESA\_query\_renderer): OpenGL renderer string: llvmpipe (LLVM 10.0.0, 256 bits) **xrandr --verbose** xrandr: Failed to get size of gamma for output default Screen 0: minimum 3840 x 2400, current 3840 x 2400, maximum 3840 x 2400 default connected primary 3840x2400+0+0 (0x2b0) normal (normal) 0mm x 0mm Identifier: 0x2af Timestamp: 36805 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: \_MUTTER\_PRESENTATION\_OUTPUT: 0 non-desktop: 0 supported: 0, 1 3840x2400 (0x2b0) 811.008MHz \*current h: width 3840 start 0 end 0 total 3840 skew 0 clock 211.20KHz v: height 2400 start 0 end 0 total 2400 clock 88.00Hz **sudo lshw -c display:** \*-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga\_controller bus\_master cap\_list configuration: latency=0 resources: iomemory:600-5ff iomemory:620-61f memory:a9000000-a9ffffff memory:6000000000-61ffffffff memory:6200000000-6201ffffff ioport:3000(size=128) memory:aa080000-aa0fffff \*-display UNCLAIMED description: VGA compatible controller product: Intel Corporation vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 01 width: 64 bits clock: 33MHz capabilities: pciexpress msi pm vga\_controller bus\_master cap\_list configuration: latency=0 resources: iomemory:620-61f iomemory:400-3ff memory:628c000000-628cffffff memory:4000000000-400fffffff ioport:4000(size=64) memory:c0000-dffff memory:4010000000-4016ffffff memory:4020000000-40ffffffff **sudo prime-select query:** nvidia **nvidia-settings** : ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system (nvidia-settings:30665): GLib-GObject-CRITICAL \*\*: 20:15:21.464: g\_object\_unref: assertion ‘G\_IS\_OBJECT (object)’ failed \*\* Message: 20:15:21.465: PRIME: No offloading required.

> [1.831309] [drm] Your graphics device 9a60 is not properly supported by the driver in this > kernel version. To force driver probe anyway, use i915.force\_probe=9a60 > module parameter or CONFIG\_DRM\_I915\_FORCE\_PROBE=9a60 configuration option, > or (recommended) check for kernel updates. You’d need a newer kernel to support your integrated GPU. Sounds just stupid from Dell to install Ubuntu 18.04 on it. I’d recommend installing Ubuntu 20.04 and a HWE kernl with it. ---

> [@user33879](#): > > Also my have hard driver full encryption is enabled, but I can’t disable it, is this the reason that Driver could not be loaded? The nvidia driver is loading. But also is the nouveau, which should be blacklisted. The nvidiafb driver also needs to be blacklisted (maybe that’s the reason the X server quits saying it can’t run in framebuffer mode). However as said before, I’d install a newer OS and kernel. ---

Ok, Thank you for your response, Iet me try the configuration change first. we are still using 18,04 for development, 20.04 will cause other problems. if it doesn’t work, I will try upgrade OS.
