[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from [email protected] --- I have the same problem. I posted more info about it on the Forum from Arch Linux, as well what I already tried and some ideas: https://bbs.archlinux.org/viewtopic.php?pid=2268957 What is happening here: 1. The Laptop Awakes. 2. kwin (?) sends some handshake to HDMI (monitor in stand-by). 3. The monitor starts turning on. 4. HDMI handshake request times out from KWIN. 5. The monitor is ON but it has no signal. 6. Monitor turns off again. 7. Placeholder screen has blocked input access. (Need to open lid, press enter, close lid) 8. HDMI monitor is ON again and everything is good until the next suspend state. How it could be mitigated: 1. Increase the time-out to X seconds and try to reach the same monitor again or try to connect multiple times for X seconds. 2. Allow receiving input (keyboard, mouse) inside the placeholder screen itself. (If I could press enter, the monitor would wake up (like opening the lid) Some logs from the forum post: ``` Oct 22 14:34:35 theluga plasmashell[1178]: requesting unexisting screen available rect -1 Oct 22 14:34:35 theluga plasmashell[1178]: requesting unexisting screen available rect -1 Oct 22 14:34:35 theluga plasmashell[1178]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga kscreenlocker_greet[2644]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga org_kde_powerdevil[1200]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga kwin_wayland[1013]: Could not find a matching X RandR CRTC/output to set as primary for KWin::DrmOutput(0x648acddd91c0, name="HDMI-A-1", geometry=QRect(0,0 1920x108> Oct 22 14:34:35 theluga kwin_wayland[1013]: Could not find a matching X RandR CRTC/output to set as primary for KWin::DrmOutput(0x648acddd91c0, name="HDMI-A-1", geometry=QRect(0,0 1920x108> Oct 22 14:34:35 theluga yakuake[1368]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga xdg-desktop-portal-kde[1408]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga ksecretd[1415]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga kdeconnectd[1361]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga kactivitymanagerd[1194]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga polkit-kde-authentication-agent-1[1199]: There are no outputs - creating placeholder screen Oct 22 14:34:35 theluga kwin_wayland[1013]: Could not find a matching X RandR CRTC/output to set as primary for KWin::DrmOutput(0x648acddd91c0, name="HDMI-A-1", geometry=QRect(0,0 1920x108> ``` -- You are receiving this mail because: You are watching all bug changes.
