Before installation everything worked fine but after not

Post by Noxebe »

Good day everyone,

I have a problem with Linux Mint. First of all I couldn't boot live session properly so I serched for an option of "nomodeset".
It wroked. I was so glad about it. I could operate through system perfectly. Graphics was smooth and broweser worked at full speed.

But after installation I couldn't boot system from HDD. So i used "nomodeset" as well. The system started but... Everything works slow.
I mean not from the hdd standpoint but graphics.
So what's the difference between live session and installed one?

I have an AMD rx 570 graphics card.

How can I solve this problem? How can I make this work properly?

Hello Noxebe and Welcome to Linux Mint forums,

Unfortunately AMD has an on again off again track record with Linux For awhile they had some pretty good Linux drivers for their graphics cards but they stopped for awhile and started again. But did not make their drivers retroactive so it can be very confusing as to which cards work and which do not.
First thing I would try would be to go to Menu>Administration>Driver Manager and see if it offers any alternatives to the opensource driver.
If nothing there (note: give it several minutes to find your hardware) you may be able to find help here: https://www.amd.com/en/support/kb/relea ... -lin-18-40 select the one for ubuntu 18.04.1 Also this page may be of help https://easylinuxtipsproject.blogspot.com/p/amd.html Good Luck.

nomodeset just let's you boot. Then you are supposed to install the drivers needed to support your graphics adapter. This is explained in the Release Notes, right after the section about how to boot with nomodeset. :)

Good day again,

Thank you for the answers.
I did everything what was mentioned on the site: https://easylinuxtipsproject.blogspot.com/p/amd.html
It doesn't work.
Software manager says it's installed: amddisplaydriver.

The thing that is interesting (I was trying to point this out in the title of this thread) graphics was perfect before installation with "nomodeset"(!) enabled.
But after installation it:

1. Doesn't lunch at all. It hangs on black screen.
2. With "nomodeset" it works slowly/chunky/lumpy.

Do you have any other ideas what could go wrong?

Regards.

Did you try the driver from AMD the one for Ubuntu 18.04.1 It says it supports your card. Follow the instruction on the first link I posted in my first reply.

Because AMD has this on/off thing with linux, I moved on to NVIDIA. AMD development on linux seems to have has come to an abrubt stop. At some point I read that AMD has hired more poeple to help with linux driver development, but I have yet to see anything updated. In order to use the amdgpu drivers, you might have to downgrade the kernel to 4.15. I am currently running a custom kernel based on 5.5. My gpu is an EVGA GeForce GTX 1060, that I picked up new for about 150 bucks. I came form and XFX ATI Radeon R7 260x, which still worked perfectly, but I had issues with it on anything higher than linux kernel 5.0. Mint 19.3 comes stock with kernel 5.0.0, but immediately upgrades to 5.3.

Good day again,

Yes I tried this driver 15 minutes ago and terminal said it's not supported. I tried this driver before - under Ubuntu and it didn't work either.

Ok. For the time being I installed CentOS. It just works. But I wish I will return to Linux Mint some day.
