Hallo Community,
ich habe folgendes Phänomen:
Wenn nach Inaktivität der Energiesparmodus sich einschaltet, Bildschirm aus, dann startet Ubuntu neu.
Ich hab mal in den Logs geschaut und das hier gefunden, weiß nicht aber nicht, ob das damit was zu tun hat:
[drm:drm_dp_send_dpcd_read [drm_kms_helper]] *ERROR* mstb 0000000037d25c08 port 3: DPCD read on addr 0x4b0 for 1 bytes NAKed
Mein Ubuntu läuft auf einem Lenovo Laptop, hier der Output von lspci:
