Re: [SOLVED] NVIDIA black screen after upgrading GPU card

Remove that config, the nvidia driver doesn't care about PreferredMode and the rest is cruft.

"startx", switch back to a TTY and see whether "xrandr --display :0 --output HDMI-1 --mode 1920x1080" allows you to get an output.
Also post the xorg log of that run.

If this works
1. you probably need a better cable
2. /etc/X11/xorg.conf.d/20-nvidia.conf

Section "Device"
    Identifier "RTX3050"
    Driver  "nvidia"
    Option  "MetaModes" "HDMI-1: 1920x1080 +0+0"
EndSection

Edit: the GPU will probably keep at higher clockrates if you're using a multiscreen setup, but I'd run conky on that thing - and share a better picture.

Re: [SOLVED] NVIDIA black screen after upgrading GPU card

It's ok, I already removed that configuration. It was just an experiment. I tried your xrandr command under secondary TTY with HDMI-1 specified, but it didn't work. Later I saw that in NVIDIA driver it's called HDMI-0.

Never mind, I have other inputs. I tried connecting the monitor via another short HDMI cable of 1.2 m and voila, the picture appeared! I usually use a 7 m cable because of my indoor environment.

Let me remind you, that 7m cable works good with 3050+nouveau, 3050+win10, 1050+nvidia. So, can I make that cable work with 3050+nvidia? Can I adjust the HDMI clockrates?

Below I have posted some information commands from this successful 3050+nvidia connection via 1.2m cable.

$ xrandr --verbose

Re: [SOLVED] NVIDIA black screen after upgrading GPU card

This is the cvt1 reduced blanking mode, you could try to add and run

◉ cvt12 2560 1440 60 -b
# 2560x1440 @ 60.000 Hz Reduced Blank (CVT) field rate 60.000 Hz; hsync: 88.860 kHz; pclk: 234.59 MHz
Modeline "2560x1440_60.00_rb2"  234.59  2560 2568 2600 2640  1440 1467 1475 1481 +hsync -vsync

or https://wiki.archlinux.org/title/NVIDIA … ubsampling

For the custom modeline you'll have to tell the driver that this is ok.

    Identifier "RTX3050"

    Option  "MetaModes" "HDMI-0: 2560x1440_60.00_rb2 +0+0"

Re: [SOLVED] NVIDIA black screen after upgrading GPU card

I should add these 2 files, right?

/etc/X11/xorg.conf.d/10-bnq.conf

Section "Monitor"
        Identifier "BenQ BL3200"
        ModelName "BenQ BL3200"
        VendorName "BNQ"
        Modeline "2560x1440_60.00_rb2"  234.59  2560 2568 2600 2640  1440 1467 1475 1481 +hsync -vsync
        Option "PreferredMode" "2560x1440_60.00_rb2"
EndSection

/etc/X11/xorg.conf.d/20-nvidia.conf

Section "Device"
    Identifier "RTX3050"
#    Option  "ModeValidation"        "NoEdidModes, AllowNonEdidModes" # this allows you to skip all edid modes and add your config below
    Option  "ModeValidation"        "AllowNonEdidModes"
    Option  "MetaModes" "HDMI-0: 2560x1440_60.00_rb2 +0+0"
EndSection

But how to add this mode for virtual TTY?

Re: [SOLVED] NVIDIA black screen after upgrading GPU card

I decided to set VT resolution via kernel option like this

video=HDMI-A-1:2560x1440MR@60
video=HDMI-A-1:2560x1440M@59.95
video=HDMI-A-1:2560x1440M@60m

But none of these options worked. And I stay on the

video=HDMI-A-1:1920x1080@60

Then I added 2 files described above to /etc/X11/xorg.conf.d, but got a black screen with the following messages in the Xorg.0.log

[   114.065] (II) Applying OutputClass "nvidia" options to /dev/dri/card1
[   114.065] (**) NVIDIA(0): Option "ModeValidation" "AllowNonEdidModes"
[   114.065] (**) NVIDIA(0): Option "AllowEmptyInitialConfiguration"
[   114.065] (**) NVIDIA(0): Option "MetaModes" "HDMI-0: 2560x1440_60.00_rb2 +0+0"

[   114.411] (II) NVIDIA(0): Validated MetaModes:
[   114.411] (II) NVIDIA(0):     "DFP-1:nvidia-auto-select"

Then I left only one file /etc/X11/xorg.conf.d/20-nvidia.conf

Section "Device"
    Identifier "RTX3050"
    Option  "ModeValidation"        "NoEdidModes, AllowNonEdidModes"
    Option  "MetaModes" "HDMI-0: 2560x1440_60.00_rb2 +0+0"
EndSection

and after watching black screen for about 20 seconds I got X at a awful resolution something like 800x600. I tried to set custom clocks manually

xrandr --newmode "2560x1440_60.00_rb2"  234.59  2560 2568 2600 2640  1440 1467 1475 1481 +hsync -vsync
xrandr --addmode HDMI-0 "2560x1440_60.00_rb2"
xrandr --output HDMI-0 --mode "2560x1440_60.00_rb2"

but a black screen appeared again.

So all that remains is to try other cables. My cable turned out to be 7.5 meters long and not 7 as I wrote earlier. Finally I got another 8m expensive cable and 7m cheap cable. I tried both. The expensive 8m cable - black screen as always, cheap 7m cable - worked flawlessly. Alright the matter was half a meter long.

After a couple of hours I noticed horizontal black lines on the screen, 1 pixel thick. I thought, "oh no not again". I reconnected the cable and fixed it with electrical tape. The lines disappeared and I hope I never see them again.

I think we can close this topic. If the problem happens again, I'll create a new one.
