I "Accidentally" upgraded to 16.04 from 15.10 as it would have lost support anyway in July, and now FGLRX is nowhere to be found and only one of my monitors work.


Currently screenfetch is displaying my GPU like this:

GPU: Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)

It is a Sapphire R270 and should be supported by the new radeon driver. I have tried to edit the xorg.conf file but it did nothing:

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "radeon"
EndSection

The file didnt even exist to begin with so I made a new one, but as I said it did nohting.

I have searched further and found a 10-amdgpu.conf file in

/usr/share/X11/xorg.conf.d

but I am too scared to edit there anything, since I am afraid to render my system unuseable.

There is no need to install the open source drivers. They are already installed by default.

You can check which kernel module is used by running

lspci -k | grep -EA2 'VGA|3D'

in terminal. It will show something like this

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV620/M82 [Mobility Radeon HD 3450/3470]
    Subsystem: ASUSTeK Computer Inc. Device 19d3
    Kernel driver in use: radeon

GPU: Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits) looks correct.

  • so could be the reason that I cant use multiple monitors and everything feels so slow ?

  • This is another question why the system works slow.

  • I suggest asking a new question. Describe what is the problem and post there the output of lspci -k | grep -EA2 'VGA|3D|Display'. This question has been answered and it does not help the actual issue.
