How to switch my GPU

I have a Integrated Graphics card being used as Default , I want to Switch to Radeon 520 which I presume wont have laggy desktop experience , Is there any way to do it ? I am using Cinnamon and all packages are updated. Thank you in advance

some more info on your setup would be helpful to both you and anyone willing to help you.

Sorry for that but what more info should I provide?

please test if

DRI_PRIME=1 glxgears

works for you.

BTW in your case, i’d switch to a smaller desktop. Your problem is most likely the in general weak hardware in terms of CPU and much more HDD. The change to your radeon will increase the power usage, but I dont think it will change much in terms of desktop performance.

We have a thinkpad here with the same CPU, but a SSD that can run GNOME just with without to much fuzz and lag (since 3.20). It’s totally not possible to run Cinnamon smoothly on there. KDE runs very smooth, XFCE also.

It does show on average 60 fps, My system takes lot of time to boot up to graphical dsplay so I think there must be problem with GPU rendering, Should I use KDE instead ? I hate how laggy it is , I think though switching to AMD GPU might fix it . Just dont know how to do it

in both cases your graohics driver (if AMDGPU or radeon) will use radeonsi to provide you graphics. There will be no change at all. There is no need to try this.

Why do you think that? If the boot takes long, the bottleneck often is the CPU or the HDD. To reach the desktop is a CPU and HDD heavy task. So yeah, you could try the KDE. Maybe this will work much better. But boot-up-times will most likely not get shorter :wink:
