Are there some relevant messages in dmesg or .xsession-errors ?
That I interpret as switching off of the GPU.
What are the specifications of the graphic card regarding maximal electric
energy consumption? On the web I found something like around 160 Watts.
Can your power supply unit in the computer deliver that?
You said in another e-mail that your computer worked with Windows but maybe the
driver is better with energy saving.
I use the kernel parameter "radeon.dpm=1" for saving some energy with my GPU.
In the file /var/log/dmesg there appears then a lot of output regarding dpm
(lines containing [drm]).

That is uptodate.

No, I just asked because some CPUs have builtin GPUs.
