(Sorry for my English. It is not my native language)


I had until now Video card built on the motherboard (Intel4600). Yesterday I bought my new video card (Rx460). And it works great on windows.

I also use tails os 2.91 From my 16 gb usb flash drive. my problem is this that rx460 does not work well with tails. It works slowly and the video is clipped.

on intel4600 tails work great That's why I know this is a problem of the my new video card.

I think the problem is the drivers. How do I install video card drivers in tails?

Hi & Welcome to LQ-

Become 'root' use 'sudo'
CD to the directory where the driver is and use dpkg --install <name of driver>.

Here's an example:

Is this your new Rx460 GPU?

Here's the Proprietary Driver if you have an interest.

-:::-Keep in mind that whatever you install on a Live system will only stay in memory. A fresh reboot the software will have to be installed again. Not sure if that applies to drivers.-:::-

Now that I'm trying to run tails that showing me this screen (https://postimg.org/image/6950zed9z/)

You know If it possible to Use two graphics card at the same time? In other words I installed the Rx460 And my old video card that built on to the motherboard (Intel4600) stopped working why? There is a possible to Choose in bios Which video card I want to use? Do you understand. what do I mean?

I can not do what you said Because tails will not up. Every time I try to run tails that showing me this screen (https://postimg.org/image/6950zed9z/). You have a solution to this problem?

I think you can choose which GPU that you want to use in the BIOS; you'll have to look.
IF not you will have to blacklist the onboard GPU.
Just open your /etc/modprobe.d/blacklist file and blacklist the onboard GPU by disabeling the driver for it.

This error that you are getting:
indicates one of 2 things. Either there is a problem with Plymouth or there is an issue having 2 different graphic cards.I do not have experience at manipulating Plymouth, sorry.

This might help. I'm not sure if Grub is the problem. I'm thinking that there is more likely conflict between the 2 graphic cards.
