Title:
amdgpu needed blacklisting of radeon module
Status in xorg-server package in Ubuntu:
New
Bug description:
I have installed a new Radeon card alongside the old one:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Baffin [Polaris11] (rev cf)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RV730 PRO [Radeon HD 4650]
Booted Ubuntu, and the console just froze when switching to graphics mode. I
was not able to switch consoles with ctrl+alt+f1/ctrl+alt+f2, despite having
NAutoVTs=6 in /etc/systemd/logind.conf.
I could login via SSH, but all I could see is that X wasn't able to find any
screens, but without any clues why:
[ 11.142] (EE) No devices detected.
Finally when running X -configure as root I got the following helpful log
message before crashing:
amdgpu_device_initialize: DRM version is 2.49.0 but this driver is only
compatible with 3.x.x.
After some searching I found that I should blacklist the radeon module
to get the amdgpu module working, and indeed adding this file fixed
it:
/etc/modprobe.d/blacklist-radeon.conf
# cannot load both amdgpu and radeon
blacklist radeon
Then: sudo update-initramfs -u -k all
Another workaround is to remove the old graphics card, that made
booting work again.
I think there is a bug here though: X shouldn't crash: it should be
able to use at least one of the two graphics card drivers, and the
text console should still be operational even if it failed to
initialize graphical mode, so that the user can log in, investigate
and fix things from a local console, instead of relying on fixing
things over SSH.
