charset=utf-8 Content-Transfer-Encoding: 8bit I have a 21:9 ultrawide monitor connected to an RX 570 with the amdgpu driver. I'm still using the 4.14 kernel since with later kernels I can't get the driver to allow use of the full resolution of 2560x1080 and I'm limited to regular HD, ie 1920x1080. The latest kernel I've tried is 5.4-rc2. My distro is NixOS unstable-small. I have two other monitors (16:9 and 16:10) connected to the same graphics card.

Is there anything I can do to work around this or try to fix it? I had a look at the driver sources but couldn't find where the mode is set. I'm happy to try things if someone can point me in the right direction, even if it's just to gather better info for a bug report. Using such an old kernel is becoming really inconvenient.

Some additional info about the situation on 4.14 that may or may not help:

1. The resolution is limited with Wayland but not with X11

2. When the system boots up the resolution is square and the image is squished horizontally with many columns dropped, both during the boot process and at the gdm login screen. It's not until after I log with X11 that the resolution is set correctly.

3. The output of xrandr --props is below.

TIA for any help.

charset=utf-8 Content-Transfer-Encoding: 8bit I have a 21:9 ultrawide monitor connected to an RX 570 with the amdgpu driver. I'm still using the 4.14 kernel since with later kernels I can't get the driver to allow use of the full resolution of 2560x1080 and I'm limited to regular HD, ie 1920x1080. The latest kernel I've tried is 5.4-rc2. My distro is NixOS unstable-small. I have two other monitors (16:9 and 16:10) connected to the same graphics card.

Is there anything I can do to work around this or try to fix it? I had a look at the driver sources but couldn't find where the mode is set. I'm happy to try things if someone can point me in the right direction, even if it's just to gather better info for a bug report. Using such an old kernel is becoming really inconvenient.

Some additional info about the situation on 4.14 that may or may not help:

1. The resolution is limited with Wayland but not with X11

2. When the system boots up the resolution is square and the image is squished horizontally with many columns dropped, both during the boot process and at the gdm login screen. It's not until after I log with X11 that the resolution is set correctly.

3. The output of xrandr --props is below.

TIA for any help.
