Hello, I have tested some livecd, and my OS.
On the config:
A6-3650 -> then gpu SUMO
1 screen on HDMI
1 screen on DVI
F1A75-I DELUXE
Manual say that's work, the efi boot screen is show on both screen.
But under linux I have just the HDMI connected screen that's work. The other is
just disconnected (no signal it say, then same when is not connected or in
sleep).
Software tested: Ubuntu/Kubuntu/Gentoo. I have try the git ati drivers (git
kernel crash here). At the mode settings the second screen is close too.
It's 2h to assemble this computer (missing hdd, power supply, then I need use
of my main computer), then if you can group your query.
I have noted the dmesg, lspci, ... nothing execpt:
[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing E262 (len
2585, WS 4, PS 4) @ 0xE94C
drm: registered panic notifier
I have try both under KDE, it crash.
The both screen is detected.
