External Monitor not detected anymore

Hello,

This time I'm facing a serious issue.

After installing the latest updates, my external monitor is not detected anymore. I tried switching between various Nvidia drivers but had no luck. I'm currently using Nvidia-driver-440 and my laptop's graphics card model is GeForce GTX 1050 Ti Mobile. Furthermore when I launch nvidia-settings from terminal I see the following errors.

ERROR: NVIDIA driver is not loaded


ERROR: Unable to load info from any available system


(nvidia-settings:10847): GLib-GObject-CRITICAL **: 01:30:29.665: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 01:30:29.668: PRIME: Requires offloading

** Message: 01:30:29.697: PRIME: is "on-demand" mode supported? no

Any ideas what might be wrong? Anyone else having issues with external monitors?

In terminal, could you please try:

Code:

sudo rm /lib/modprobe.d/nvidia-blacklist.conf

then

Code:

sudo update-initramfs -u

I do not have such file nvidia-blacklist.conf in this path. I did try the second command though. Didn't make any difference

Ok, yeah if you do not have the file, then the command will do no good. I need to run someone to a Dr. appt but hopefully the thread will continue with suggestions- when I get back I will try looking into it more to see if I can provide any kind of help...

Thanks for your interest. I tried most of the suggestions found online but none of them worked. My last resort would be to reinstall zorin or some other distro. But I'll wait in case someone comes up with something I haven't tried yet.

btw when I boot ZorinOS from flash drive my external monitor is recognized and used normally. So maybe this is a kernel issue or some other update that broke the system.

Hi, Could be a combination of kernel and nvidia driver update - I always stick to the nouveau drivers - never the proprietary ones. I hope you have earlier kernels still present on the system. If you can't see GRUB at boot time, press the left shift key during boot to view GRUB and choose an earlier kernel - if that works o.k. you know what the issue is.

Well I didn't believe there are people who actually stick to the nouveau drivers. They are c*** plus I don't think they offer support for external monitors anyway I will install Ukuu today and do some kernel roll backs and see if this works. I will keep you posted.

Yes roll back is what I would do. You MAY try rolling forward, too. See if an issue was patched in a later release than Zorin has rested/released.
-And be sure to remove Ukuu when finished lest you be killed by voracious nagware...-
Please update.

Nouveau information here:

https://nouveau.freedesktop.org/wiki/

I found that proprietary drivers on Zorin never work well - and technically can be a security risk.

So I installed Ukuu and rolled forward to kernel 5.5.2 and everything is back to normal. Second monitor is now detected normally both on display port and HDMI. Nvidia settings can also see the monitor. Damn you linux and your broken kernels

Good to know you are sorted.

I'm trying to get my Thinkpad T420 to connect to my TV using a DisplayPort to HDMI cable but the TV doesn't pick it up.

I tried installing to the latest kernel and nothing.

Any suggestions/advice?

Check the "Facepalm" things first, like the T.V.'s input settings. That one gets us all... As sson as we think our foreheads are safe and we get fooled.
Which Distro are you using, Zorin 12?15? Core?Lite?
Edit: I recall from another thread- you are running 15 Lite.
What is the output from

Code:

xfsettingsd -V

Can you paste in the output from

Code:

inxi -Fxz

Unplug your T.V. from the HDMI port, open terminal and input

Code:

xrandr

then plug in the T.V. to the HDMI and try to connect.
Please update.

I am using Zorin 15 Core on this laptop.

I'll give that a shot later today, thanks.

If using Core, then just paste output of:

Unplug your T.V. from the HDMI port, open terminal and input

Code:

xrandr

then plug in the T.V. to the HDMI and try to connect.

Thanks. I'll update later today. Am I running these codes in the terminal while the displayport is connected?

Either, works for the 'inxi -Fxz.' The 'xrandr' is a command, not an info-request, so would be run just prior to you lugging in the monitor. Er., T.V.

Most of the time, when you see a small command in code tags on Linux discussion forums, it refers to a terminal command. You won't break anything (or at least, it is exceptionally rare) by trying a command in terminal that isn't a command. So, if you could - consider that your default setting when you see an item in code tags.
To open a terminal, hit ctrl+alt+t on your keyboard.
Or you can select it from the app menu. The terminal emu is a lot like the DOS command prompt on wind0$
For folks migrating to Linux from windo$, the terminal appears intimidating, but it is actually a very powerful and informative tool. When I came over to Linux, I initially tried to avoid the terminal and use GUI as much as possible because that is what Windo$ had trained me to be used to. I learned swiftly to get over that. I do the vast majority of things from the terminal, these days.

I got that part, I was just assuming that I needed to copy and paste the output of the first command somewhere else.

Those commands didn’t seem to work.

Odd... works on my copy of Zorin 15... Maybe you need to install inxi, first
run

Code:

sudo apt-get install inxi

then once installed, run

Code:

Yup, installed inxi and ran those commands. Still not able to connect to my TV.

is not for making the connection, but to give an output that shows your computer specs like graphics card. I am asking if you can paste the output from that in terminal onto here so we can see if there is any hardware conflict or something else.
The problem with this issue is that the HDMI port may have a fault, the cable may have a fault, the port on the T.V. may have a fault... For example if you try making the connection using VGA with a VGA cable and no problems there, then we KNOW with certainty that the issue lies in the HDMI side and we can then try to narrow it down to Hardware or Software.

We already covered your Manufacturer info above;
Open Software Center and click the Menu button, then click "Software Sources"
Checkmark the box "Proprietary drivers for devices."
You'll need to give it your password, then authenticate.
Now, go back to your App menu and go to ALL or System category- Look for "Additional Drivers"
Open that...
Click the proprietary driver labeled with your manufacturer's brand from the inxi cmd we did earlier and above and click the "Enable" button. If the wrong proprietary driver is already enabled, click it and click the "Disable" button.
