GTX 1050 ti and Ubuntu 20.04

Display problem in Ubuntu 20.04
when I use
“Using server - New display driver from xserver-org-video-new” I do have a 1920X1080 display. However, when I choose the driver installed by default:
“Using Nvidia metapackage from nvidia-driver-455 (owner)”
on reboot, I only have a 1024X768 display

my graphics card is an nVidia GTX 1050 ti 4Go; I am on the VGA output of the graphics card

nvidia-smi gives me "NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. "

nvidia-settings gives me this:
"ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
(nvidia-settings: 19184): GLib-GObject-CRITICAL **: 15: 09: 40.911: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed
** Message: 15: 09: 40.914: PRIME: No offloading required. Abort
** Message: 15: 09: 40.914: PRIME: is it supported? No "

Can I get some help? thank you

Please run as root and attach the resulting nvidia-bug-report.log.gz file to your post.

here’s the attached file nvidia-bug-report.log.gz‌. I hope it’ll be useful

I hate to break it to you, but I think your “GTX 1050 Ti” is fake. It’s an old Fermi GPU that’s been hacked to report itself as a 1050 Ti. Note that the audio function still reports itself as GF116 even though the graphics function misreports itself as a GP107:

/usr/bin/lspci -d "10de:*" -v -xxx

06:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1) (prog-if 00 [VGA controller])
06:00.1 Audio device: NVIDIA Corporation GF116 High Definition Audio Controller (rev a1)

Another telltale giveaway is that Pascal and newer GPUs don’t support VGA outputs, so if your card has one of those then it’s bogus.

The driver queries the actual capabilities of the GPU rather than just going based on the PCI device ID, which is why it’s reporting your GPU as not supported. Fermi GPUs are only supported in the legacy release 390 series of drivers.

Can you return this GPU for a refund?

I bought it in 10th of june 2019‌ on Is Warranty OK ? And return to whom ?

I’m not familiar with, sorry. You’ll have to work with them to try to get a refund, I guess.

thank you for all. I’ll try to have a refund
