Issues with going from amd to Nvdia

[Hubert797]

Hello all, I'm new to this forum, have been using Debian for a few years. I was previously using an amd rx580 gpu, however need Nvidia for the time being so I'm currently trying to get my gtx 1070 working. This is what I did, starting from a working amd setup:

Code: Select all

apt install linux-headers-5.5.0-1-amd64

apt install nvidia-kernel-dkms

apt install nvidia-driver

apt autoremove libgl1-mesa-dri xserver-xorg-video-ati

poweroff

Here I replaced the rx580 with the 1070 and attempted to boot. I got a command line, so installed kde and rebooted again. This time, I got in, but the resolution was very low, and kde wouldn't let me change it. So, I installed the nvidia drive again:

Code: Select all

apt install nvidia-driver

It installed a variety of new things, after rebooting, I got a black screen and after a few seconts a cursor. Switching to tty with ctrl alt F2 worked fine, and after installing xinit I can now get in with startx. However, I'm pretty sure the system is using the integrated graphics of the motherboard, not the nvidia card. Glx gears does not work.

Code: Select all

glxinfo | grep renderer

outputs:

Code: Select all

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

X Error of failed request: GLXBadContext

Major opcode of failed request: 151 (GLX)

Minor opcode of failed request: 6 (X_GLXIsDirect)

Serial number of failed request: 54

Current serial number in output stream: 53

And at this point I am stuck. Anyone know how to fix this? Starting with nomodeset does not help, and secure boot is disabled.

Thanks, Hubert.

However, I'm pretty sure the system is using the integrated graphics of the motherboard, not the nvidia card.

Surely the motherboard graphics has a different output socket from the Nvidia card. Which one is your monitor plugged into? Does your UEFI setup menu have an option to disable the mobo graphics? That's what I had to do on my desktop PC.

I looked into this and it appears as if my motherboard doesn't actually have integrated graphics, (the hdmi port is there only if the cpu does I guess, which mine does not), so that's my mistake. It must be running on the Nvidia card then, which makes this even more confusing.

Please install inxi and post here the output from

Code: Select all

inxi -SCG

You failed to note if you installed the compilers to build the drivers, as noted in the Debian wiki. Plus gave no output from the install commands, which would have shown if you did. I suggest "get thee to the wiki", follow the directions, especially for running nvidia-detect first, and then get back to us if the problems persist.

Output is:

Definitely seems bad that it says N/A for opengl.

I suggest "get thee to the wiki", follow the directions, especially for running nvidia-detect first, and then get back to us if the problems persist.

I'm pretty sure I followed the Debian wiki exactly, but I can always restart the process and make sure, along with noting all the outputs. However, I have not found a way to run nvidia-detect as the first step, as I can't even get into tty with the nvidia card installed without first installing nvidia-driver. Obviously running it with the amd card in the system won't be very useful.

The inxi output shows that the driver built successfully, but as noted, no openGL acceleration at all.

There are Nvidia GL files that should have installed automatically and it "just works", so I am stumped. Maybe the mixture of testing and Sid has broken something. I backported the 440.82 driver the other day for my MX Linux Optimus laptop, and it works fine:

Code: Select all

$ optirun inxi -G
Graphics:  Device-1: Intel UHD Graphics 630 driver: i915 v: kernel 
           Device-2: NVIDIA GP107M [GeForce GTX 1050 Ti Mobile] driver: nvidia v: 440.82 
           Display: x11 server: X.Org 1.20.4 driver: intel resolution: 1920x1080~60Hz 
           OpenGL: renderer: GeForce GTX 1050 Ti/PCIe/SSE2 v: 4.6.0 NVIDIA 440.82

Might be a reinstall coming my way... I shouldn't have a mix of Sid and testing though (at least I hope not), I'm on Sid and don't recall ever using any testing software. Not sure why it shows bullseye/sid, but it's shown that right from the start.

Not sure why you installed nvidia-kernel-dkms separately when it's a dependency of nvidia-driver anyway. Also not sure why you reinstalled KDE when presumably it was working with your AMD card. I doubt these would have caused your problem though.
I just checked my Buster/Nvidia system using nvidia driver and libgl1-mesa-dri is installed and not flagged by apt autoremove. Maybe reinstall that. It's a long shot but nothing else comes to mind.

A pure Sid system shows that, no problem there.

Make sure secure boot is off in your UEFI, the nvidia module won't load due to a key being out of date, at least that was the problem I had a month or two ago. Supported by the fact that inxi is reporting the nvidia module unloaded, not missing or using the open source module.

Everything built fine, but the kernel couldn't load the nvidia module, leading to a lot of bad graphical issues. Disabling secureboot and the subsequent boots were all flawless. You can check in dmesg after booting, just grep -i for nvidia. If there is a message about not being trusted and keys missing / out of date you know that is the issue.

OP's inxi shows nvidia module is loaded, but no OpenGL.

Just had another thought - GP104 cards need non-free firmware. Install the package firmware-misc-nonfree and reboot.
