This question already has an answer here:
lspci | grep -E 'VGA|Display'
shows that it has found my graphics card which is in the supported list and works fine on windows:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
dmesg doesn't show any errors.
glxinfo | grep OpenGL
shows that it is not using the GPU:
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits)
Is there any way to force Ubuntu to use the GPU as I am currently unable to watch youtube and run phpstorm at the same time without considerable lag.
