When you change these settings and click apply, are they in fact applied as expected? Or does nothing happen? (In reply to Nate Graham from comment #1) > When you change these settings and click apply, are they in fact applied as > expected? Or does nothing happen? The combobox changes but otherwise nothing happens Thanks. Can you use kscreen-doctor to change the settings? Or does that fail too? (In reply to Nate Graham from comment #3) > Thanks.

Found mode "8" "1920x1080@60" kscreen.doctor: Output 1 set mode "8" kscreen.doctor: setop exec returned KScreen::Config( KScreen::Output(1, "eDP-1", connected enabled priority 1, pos: QPoint(0,0), res: QSize(2560, 1440), modeId: "8", scale: 1.65, clone: no, rotation: KScreen::Output::None, followPreferredMode: false) ) So even kscreen-doctor does not work, thanks. Does any of this work in the Plasma X11 session? If so, then the issue may be in KWin. (In reply to Nate Graham from comment #5) > So even kscreen-doctor does not work, thanks.

Maybe kscreen's backend is broken pretty badly for your hardware, or maybe the hardware or its firmware/drivers aren't behaving properly.

It's a Linux-by-default device so that would be really unfortunate lol. I'll try with another distro just to check Please attach the output of drm_info, most likely the 60Hz mode is not advertised by the display but generated by Xorg and KWin and then rejected by the driver for some reason. Does only the specific 60Hz mode not work, or can you still change the resolution to a different one? Created attachment 171405 [details]

You can report the modes not working to https://gitlab.freedesktop.org/drm/i915/kernel/-/issues, though I'm not sure they'll really consider it a bug, as they're not guaranteed to work anyways |
