Screen Rotation and Distorted Display Issue After Installing Ubuntu 20.04 on Steam Deck #80
Comments
So I guess I'm confused as to what you want or expect me to fix here. The setting So for Ubuntu 20.04 (why not try newer LTS 22.04?), is the GDM login screen coming in with the portrait setting as I'd expect? If so, this is not a rEFInd configuration or problem to address. My suggestions would be to search about how to solve the GDM login screen rotation issue, if this is the root of your complaint. Once you're logged in to a graphical session, taking care of the rotation there is just a matter of adjusting display settings. So again, I don't know what you expect me to do or 'fix' here. |
I am aware that there is Ubuntu 22.04 available, but due to internal reasons, I need to use 20.04. |

Okay, so this confirms my suspicion that rEFInd is doing its job properly since your GRUB screen (the first picture) is oriented properly. So that leaves us with this being a GDM and/ or other Ubuntu display problem. Monitor rotation seems to have been a problem with older Ubuntu versions. When I had used Kubuntu 22.04 on my Steam Deck, I did not witness similar behavior, but that could also be SDDM differences from GDM or KDE Plasma versus Gnome. In any case, please try some of the proposed things from here. This seems to really be an Ubuntu settings problem. Since your docked larger monitor displays properly, you should be able to tinker and experiment with settings from there. Please let me know how it goes. Thanks. |
I encountered an issue after installing Ubuntu 20.04 on the Steam Deck where the screen was displaying vertically. At that time, the 'resolution' value in the 'refind.conf' file was initially set to 3. To change the screen to a 90-degree rotation, I modified the 'resolution' value to 0, 1, and 2.
The screen did rotate horizontally, but as shown in the picture below, the entire screen was distorted. Subsequently, even after changing the 'resolution' value back to 3, the display issue persisted on Ubuntu when running on the Steam Deck.
When I connect an external monitor to the Steam Deck, it displays correctly on that monitor, but the Steam Deck's screen remains blank.
I have attached the /esp/efi/refind/refind.conf file and images of the Ubuntu display output (including a photo of the distorted screen issue on the Steam Deck and an external monitor).
