*** This bug has been marked as a duplicate of bug 484037 *** I have the exact same problem. I can see that this is a duplicate of 464037 but that one is a little different, this covers my situation exactly. I have to unplug and replug the monitor, then it returns to the correct resolution. Linux/KDE Plasma (Fedora): KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 Graphics card is Intel + Nvidia Ok, re-opening this one. Please attach the output of drm_info when the resolution is wrong I have attached four files. correct.txt shows the output of drm_info BEFORE the display is turned off. incorrect.txt shows drm_info AFTER it has turned off and turned on again. I have also attached two screenshots, config_correct.png shows the configuration dialog when everything works fine. The display_arr_incorrect.png is a screenshot of the entire screen with the right half (sensitive parts) cropped. But you can see that the external display stayed at the same position with incorrect resolution while the internal display remained correctly positioned and sized. I saw this bug appear in other way as well, last time the external monitor moved to the top right of the internal monitor without a gap but also with a 640x480 resolution. The flow for me: - display gets locked after a timeout, SDDM is shown - after a while, both monitors are turned of correctly - when I moved the mouse, SDDM comes back as expected but the external monitor has the 640x480 resolution Also it happened to me that this issue only occurs on the first two suspends, the third time the display came back properly. Please let me know if you need more info. Created attachment 172542 [details]

The driver reports 640x480@59.94 as the only mode. Please report this to NVidia (https://forums.developer.nvidia.com/c/gpu-graphics/linux) |
