If it worked with the standard Debian kernel (whatever mystery release you're running), and you got the kernel from backports, the odds are that you need to upgrade the firmware package from backports also.

what i need to set in kernel to use radeon open driver ? Can you write in points what i need to do

[cuckooflew]

Do you read what they say and ask ?
Maybe if you just give the information as requested,then he can give more specific instructions.

additional note:

Code: Select all

lsb_release -a

will give the release info , 'uname-a ' as requested will give the kernel information needed , so he can explain what needs to be done.

i want to use radeon driver

[stevepusser]

OK, better, but what happened to "apt policy firmware-amd-graphics"? If you can't do a simple command after being asked to do it twice, nobody is going to want to waste time on you. Not to mention that you still haven't said if it was working on the stock kernel. Maybe you should update to Buster.

Where did you get the 5.6.14 kernel? It's not in any Debian backports repo for Stretch, and I haven't been able to backport the Debian version on Stretch myself.
