I bought recently a Lenovo E490. This laptop only comes with Windows 10. So I made a new partition and installed Ubuntu on it. Used manly for programming, but sometimes I playing one or two rounds of CS:GO.

The specs are:

  • Intel i7, 8th generation
  • 16 gig RAM
  • 512 SSD
  • Radeon RX 550X / Intel UHD 620

But I only could play on ultra low settings with a resolution of 1600x900. I figured out, that Ubuntu doesn't used the dedicated rx500x. So I tried to used switcheroo-control. Didn't changed. I set DRI_PRIME=1 steam. Also didn't brought the beneficial change.

But what all these steps above did, the game crashes without any error and I get thrown to my desktop and the game ended.

I also tried to install the amdgpu-pro driver, but I did that, I couldn't start up ubuntu anymore. Had to remove that from the cli.

So I just want to have the basic setup when I installed Ubuntu 3 months ago. Is there a reset option? Of course without losing my local git branches, etc. I did every week a backup with dejavu.

  • That brought me on the right track! Also check out the program configure-debian – Maxstgt Dec 2 '19 at 18:26
