I've been attempting to try out Unity 8 on both 16.04 and now 17.04 with no success.
As soon as i login, all I get is a black screen. If I then get console up and login there and then try 'startx', then I get a background screen with an 'X' as cursor and that's it. Nothing else at all. I'm fairly new to ubuntu so be gentle... I suspect this is down to my graphics card & drivers ?
I am on a laptop with an AMD R7 M360 (Also with intel integrated) and have to use the default drivers. When looking for amd-pro drivers it seems there are not any for my exact card model (http://support.amd.com/en-us/download/linux). I've seen mentioned that open source drivers have problems with Unity 8/Mir and so am wondering if the lack of amd-pro drivers for my card could be causing this unity 8 failure for me ?
Anything else I can try ?
If I run lspci -k to see what comes up, I get 2 entries for my video:
0:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)
Subsystem: Lenovo HD Graphics 520
Kernel driver in use: i915
Kernel modules: i915
And:01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445] (rev 81)
Subsystem: Lenovo Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445]
Kernel driver in use: amdgpu
Kernel modules: amdgpu
I'm confused as to which graphics card/system is being used by ubuntu. Ideally I'd like to just be using the AMD one, so is there a way of disabling one ? I could try disabling one or the other and see if Unity 8 works with either the Intel or AMD card only ?
