Description Dick Gevers 2019-01-08 19:13:49 CET

Description of problem:

Laptop HP with AMD Radeon R5.

Live media (64 bits) show boot media but after entering an option nothing seems to happen anymore.

If I remove "splash quiet" I see many many boot messages for a second but
thereafter the screen is black and stays that way...

I tried adding the blacklist parameters: rd.driver.blacklist=radeon 
rd.driver.blacklist=amdgpu and indeed I got a lot further !

I now get all the boot messages and see after 5 to 10 minutes that network
is active. With tty2 I can login as live and see X is not running.

With XFdrake I did not manage to get a working setup; each time it is:
"error (EE) Fatal server error"

Bug report after discussion with MartinW on QA ML

With 6.1 and 7beta1 this did not happen.

I think this is a kernel driver regression.

Mageia7 beta2 Gnome Live from USB.
Real EFI hardware with AMD Radeon HD7310 graphics (which apparently does not now require non-free driver). Boot menu results:
- Boot Live all free: worked.
- Boot Live with non-free: started, showed occasional splash screens, then stuck on a blank screen.
- Install all free: worked
- Install non-free: started, showed occasional splash screens, then stuck on a blank screen.

@Lewis, there is no proprietary driver for AMD graphics. The "non-free" menu items add the nokmsboot kernel boot option, which is needed for the nvidia drivers to work, but prevents the free radeon driver from working.

Comment 5 Thomas Backlund 2019-01-13 11:11:53 CET

I think we should alter the menu to state "nonfree nvidia" to avoid confusion.

If we ever package up the nonfree amd driver stack again we can re-visit the issue... but that wont happend for Mga7

Yes, I'd been thinking that. The only reason I hadn't already is that it's more work for the translators.

Is there a problem here? Should 'nokmsboot' kernel boot option queer other things which do not need it?
As a naive user, I always took the boot menu non-free drivers option to be system-wide, not just re video for booting. So Thomas' suggestion 'the menu to state "nonfree nvidia" to avoid confusion' is sound. Accept for the future, not M7.

Okay for me in round3, closing
