You can check what the system sees with the command lspci
According to the specs I find with the model you gave, it seems like it has an AMD RadeonHD mobile GPU, though it’s possible that variants with the same reference would have a different GPU, like nVidia. In the case of an AMD GPU, you likely have only one possibility for the driver: Mesa/Radeon, which is the free open source driver and already used by default. Please also give the output of the following command:
glxinfo | grep OpenGL
(You’ll have to install the mesa-utils package for glxinfo if it’s not already installed.)
There’s also a proprietary AMD driver (AMDGPU-PRO) but:
a) it’s not in the Ubuntu repository and still in development;
b) I don’t think it handles your GPU model (only newer generations, especially as it’s a mobile GPU).
Ok. I misunderstood your initial message. The situation is a bit more complicated than I thought: you have a dual GPU (or hybrid) setup: an Intel GPU used for basic usage (i.e. desktop software) and an AMD RadeonHD 7500M or 7600M used when you need better specs (i.e. games). By default, the Intel GPU is used so that you have a longer battery life and when more power is needed (launching a game), the laptop is supposed to switch on the AMD GPU. Glxinfo confirms that you’re currently on the Intel GPU.
I’m not really familiar with this kind of setup, especially with AMD GPUs. Intel/nVidia dual setups have Bumblebee/Optimus but I’m not sure what is the equivalent for AMD.
Note that if you search for infos on Google about this (something like “amd hybrid graphics ubuntu”), you might find old messages saying to use the Catalyst proprietary driver to handle the switch automatically. The development of Catalyst (also known as fglrx) has stopped just before the release of Ubuntu 16.04 and if you find an old version, don’t try to install it on a recent Ubuntu, it won’t be compatible and you will break your system. Some docs also talk about vga_switcheroo but it seems to have been removed from recent kernels.
It’s possible that there is currently no way to make the OS automatically switch to the AMD GPU on hybrid setups. I’ve found a video that explains how to switch the GPU manually but it’s not very convenient to do this.
I’m not really able to help you more on this, as I’ve never used a hybrid setup, maybe there’s someone around who has more experience about this.
Maybe in diffrent way.
I have installed the game in PlayOnLinux and working - PathOfExile.
In the graphical settings I have only to choose integrated graphics.
I would like to set up a dedicated graphics card. What is solution?
