    The update to version 25.2.0 from the control center went smoothly, but when the computer resumes from sleep, the taskbar (dock) disappears. The mouse and keyboard become unresponsive, and then the screen freezes to black. This did not happen before the update.

    In a KWin X11 environment, it freezes only when waking from sleep.
    In a Wayland (Deepin) environment, it freezes when waking from sleep and when logging out.
    And in a Wayland Treeland environment, it also freezes when waking from sleep and when logging out, and many applications fail to run or open, for example, the Brave browser and web apps created with Brave.
    The same behavior occurs on both my Asus motherboards (X415 and X515).

    Unfortunately, the latest update, version 25.2.0, dated 2026-07-13, did not fix the freezing problem when resuming from suspension.

    The solution I found for my black screen issue after suspending was the following:
    Run cat /sys/power/mem_sleep in the terminal. If the output is [s2idle] deep, switch to deep using sudo sh -c 'echo deep > /sys/power/mem_sleep'.

    Then incorporate and update GRUB:
    GRUB_CMDLINE_LINUX_DEFAULT="splash quiet mem_sleep_default=deep"
