My graphics card just died and now linux won't start

Hello people,

I'm running Kubuntu on an older PC. A few minutes ago my graphics card (a Radeon HD6770) passed away. Fortunately my PC does have a onboard vga (a crappy Nvidia something chip). So I unplugged the AMD card, switched cables and now my linux doesn't start. To be precise, I get to the SDDM login screen and can enter my passphrase but then nothing happens. I'll get a blackscreen or some colourful nonsense but not my desktop.

Interestingly Windows does start normally.

Does anyone have an idea what I can do?
Maybe this is caused by:
* My monitor setup. I used to have two display connected to my AMD card but now I can only use one of them, or
* There is a trouble because of the AMD - Nvidia switching, or
* something totaly different

Nonetheless I have no idea what to do. Can anyone else please help?

Hi & Welcome to LQ.

I'm not a GPU expert but I have a few ideas.

You will need to find out what onboard card that is so you can find a driver for it. That is if Nvidia still has a Linux driver for that card. To do that run this in your terminal.
lspci | grep -i VGA
When you installed your Radeon it over rode the onboard card. I would remove it from the motherboard completely than try installing the driver.

I'm not good with a double display, sorry.

Graphics are controlled through the xorg.conf file-

Perhapas your kernel can use the nouvea driver for the onboard Nvidia card but I'm not sure how to do that. Sorry.
***Your going to need a member that's good with Nvidia.***

It sounds like your system might still be trying to load the driver for your Radeon HD6770 card.

You'll need to type the following command to see which kernel driver is being used;

lspci -nnk | grep VGA -A2
Although, given you can get to the login screen, it might be using the correct kernel driver but not the correct X driver.

Can you also post your X log;

cat /var/log/Xorg.0.log
The above should give us something to go on. Please use CODE tags when posting the results.

Can you get to a terminal with CTRL+ALT+F2?
