Hi Lisandro, same problem with sddm, but segfault occurs later (more than 1 minute after resume). I found other logs: when a KDE session is opened, _and only in this case_, the screen flashes as soon the computer resumes. nouveau/kwin seem involved: Oct 11 23:05:40 mac-debian kernel: [ 144.724915] nouveau E[kwin_x11[1511]] fail set_domain Oct 11 23:05:40 mac-debian kernel: [ 144.724921] nouveau E[kwin_x11[1511]] validating bo list Oct 11 23:05:40 mac-debian kernel: [ 144.724928] nouveau E[kwin_x11[1511]] validate: -22 Oct 11 23:05:40 mac-debian kernel: [ 144.762168] nouveau E[kwin_x11[1511]] fail set_domain Oct 11 23:05:40 mac-debian kernel: [ 144.762176] nouveau E[kwin_x11[1511]] validating bo list Oct 11 23:05:40 mac-debian kernel: [ 144.762183] nouveau E[kwin_x11[1511]] validate: -22 Each group of 3 lines appears to correspond to a blink. Note that before upgrade to testing, the computer worked perfectly. Regards, Xavier
