Under Wayland session, if you let your logged in laptop to go to sleep (not hibernate), i.e. power led blinking, and then wake it up, you are greeted with purely white screen. The mouse cursor is visible and movable, it even changes from arrow to hand when you pass certain elements, but those elements are invisible. Trying to switch to terminal (i.e. Ctrl-Alt-F2/F3) only removes the cursor, but the screen is still white. This bug has been reported many times before, however, it was mostly for Plasma 5 and NVIDIA GPU. In this particular case, it's a AMD-based laptop which only has AMD integrated graphics and no discrete GPU, so those solutions do not work. The issue has been reported on Arch, Manjaro, Fedora. 1. I did not experience this bug on Plasma 5. 2. The laptop screen is a portrait one, unfortunately, thus I have to rotate it in grub, kde and also sddm settings to use in landscape mode while it boots. 3. When the issue is present, I can connect an external monitor and it show interface perfectly fine. But the laptop screen remains white. inxi -G Graphics: Device-1: AMD Phoenix1 driver: amdgpu v: kernel Display: wayland server: X.org v: 1.21.1.13 with: Xwayland v: 24.1.0 compositor: kwin_wayland driver: X: loaded: amdgpu unloaded: modesetting dri: radeonsi gpu: amdgpu resolution: 1707x1067 API: EGL v: 1.5 drivers: radeonsi,swrast platforms: wayland,x11,surfaceless,device API: OpenGL v: 4.6 compat-v: 4.5 vendor: amd mesa v: 24.0.9-manjaro1.1 renderer: AMD Radeon Graphics (radeonsi gfx1103_r1 LLVM 17.0.6 DRM 3.54 6.6.32-1-MANJARO) API: Vulkan v: 1.3.279 drivers: radv surfaces: xcb,xlib,wayland uname -r 6.6.32-1-MANJARO Operating System: Manjaro Linux KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 Kernel Version: 6.6.32-1-MANJARO (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen Z1 Extreme Graphics Processor: AMD Radeon Graphics
What hardware is this? I don't think I've ever heard of a laptop with a portrait-orientation screen. Also, can you upgrade to Plasma 6.1 and see if it's already fixed thete?
>I don't think I've ever heard of a laptop with a portrait-orientation screen. Most small-screen x86 devices with touch capabilities will have their screen ripped out of a portrait tablet - Valve Steamdeck, Lenovo Legion Go, many GPD's/AYANEOs, and an army of off-brand Chinese 7/8/10 inch Windows tablets. They all have naive portrait mode screen in hardware, even those that are supposed to be used in landscape like Steamdeck, which makes you jump through hoops more often than not. Anyway, what seems to have fixed it for now is switch the screen to native portrait, let it sleep, wake it up to a normal lock screen, log in, and switch it back to landscape. Now the white screen is gone, for now at least.
