Teal screen with thick black bar after installing and rebooting

[steve7233]

I switched to my GTX 1060 6GB card but the driver won't install no driver will install! My system appears to be messed up. Since Noble Numbat finally released and I haven't done much configuring of 23.10 then I decided to do a fresh install of 24.04. This thread will be continued in 24.04/post install.

Try replacing the adapter with a directly fitting cable without adapter - better even a DVI to DVi or a DVI to DisplayPort cable (if your monitor has a DVI or DisplayPort port).
Avoid HDMI if DVI-D/DVI-I or DisplayPort are available - HDMI is the inferior technology, escpecially compared to DisplayPort (only VGA is worse nowadays, because it is analogue).
And direct cables without adapter are always better, too (I have had dozens of monitor adapters in the past that caused problems).

I will try switching the card for my 1060 which has an HDMI port as my monitor only has an HDMI, VGA, and DisplayPort. I have no kind of DisplayPort cable.

I noticed my DVI to HDMI adapter from Radio Shack had a bent pin. I tried to bend it back but maybe it bent again when I plugged it in so could it be the monitor's EID info isn't transferring?

Looks like package nvidia-dkms-390, failed to configure properly with exit status 10. Remember I got it from ppa:graphics-drivers/ppa Its not part of the Ubuntu repositorys. see comment #11.

X11 but if I go to system settings > display and monitor and hover the mouse pointer over the little question mark, it says only 640 X480 is supported in this Wayland session. Could part of the system be using Wayland while another part is using X11. Maybe an improper install?

[Schwarzer Kater]

[…] I think I am using Wayland. […]

What does echo $XDG_SESSION_TYPE say?

The default session type both in Kubuntu 22.04 LTS and Kubuntu 23.10 is X11.
In 22.04 Wayland is not even preinstalled - see Overview: Kubuntu, its parent and some of its siblings.

It’s not a button. The text to the right of the keyboard is what you click on.

No it just brings up the keyboard. Maybe it doesn't work in safe mode?

I see a virtual keyboard but no other button.

From the Login Screen. Bottom left of screen you'll see: Virtual Keyboard Desktop Session:

Click on Desktop Session and choose Plasma (X11)

I see a virtual keyboard but no other button. Perhaps it is too low so it is off the screen at 640 X 480 resolution. If that is the case then I can't reach it. Is there another way?

[Snowhog]

How do I switch back to X?

I added Proprietary GPU Drivers from https://launchpad.net/~graphics-driv...ive/ubuntu/ppa with:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt update

That enabled driver manager to show the NVIDIA 390 driver and the Nouveau driver in the list but that didn't enable me to boot without going into safe mode with 640 x 480 graphics. I think I am using Wayland. How do I switch back to X?

[steve7233]

That is because the Nouveau kernel module and Mesa are already installed by default.



Or just use Kubuntu 22.04 LTS…

I just tried Kubuntu 22.04 and it still has the same teal screen problem so using 22.04 isn't the answer. Since I tried 22.04 and didn't install it then the hard drive still had 23.10 so I booted that so I could use the computer. I still have to use safe mode to load the desktop. I will try changing the graphics cards tomorrow. Ubuntu core just isn't compatible with the GTX 580.

[…] I have a 1060 6 GB in my broken computer maybe I can use that. […]

[steve7233]

It just occurred to me. Why is it that when I open Driver Manager and it populates the list why are the zero drivers listed? You would think that at least the Nouveau driver would be listed.
