एक Xubuntu 16.04 पूरी तरह से नए सिरे से बनाए गए उपयोगकर्ता के साथ पूरी तरह से पैच वाली मशीन है जो मुझे मेरी स्क्रीन लॉक करने के लिए लाइट-लॉकर का उपयोग करने के बाद अनलॉक करने देती है (भले ही लॉक मैन्युअल रूप से या टाइमआउट के माध्यम से सक्रिय हो)। स्क्रीन काली रहता है सही पासवर्ड प्रवेश पर (लेकिन संचालित)
Tty1 से लाइट-लॉकर को मारना डेस्कटॉप को प्रकट करेगा (और परिणामस्वरूप आगे लॉकिंग को रोकता है)।
प्रयास किए गए चरण:
- प्रकाश-लॉकर सेटिंग्स में और बिजली सेटिंग्स में सक्षम / अक्षम लॉक (कोई परिवर्तन नहीं)
- प्रकाश-लॉकर (कार्यों) के बजाय xscreensaver का उपयोग किया
- यदि समस्या सस्पेंड या बंद ढक्कन से संबंधित है तो परीक्षण किया गया है (यह नहीं है)
- हालांकि, काली स्क्रीन को निलंबित करने के बाद
This session is locked: You will be redirected to the unlock dialog automatically in a few seconds
संदेश प्रकट होता है - बिना किसी पुनर्निर्देशन के
- हालांकि, काली स्क्रीन को निलंबित करने के बाद
- purged + पुनर्स्थापित किया गया lightdm, light-locker और xubuntu-default-settings
- उपयोग
loginctl unlock-session
का कोई प्रभाव नहीं है systemctl status lightdm
केवल पता चलता है (हानिरहित, अपेक्षित) क्वाटलेट पाम मॉड्यूल के बारे में संदेश गायब हैं- "यह काम किया" और "यह किसी भी अधिक काम नहीं करता है" (कोई भी संदिग्ध नहीं है) और पिछले कर्नेल को बूट करने के बीच dpkg लॉग की जांच की गई (समस्या बनी हुई है)
- सत्र-आरंभ किए गए प्रकाश-लॉकर के बीच तुलनात्मक व्यवहार और मैन्युअल रूप से शुरू किया गया एक (कोई अंतर नहीं)
- उपयोगकर्ता को समूह
nopasswdlogin
समूह में जोड़ा गया (काली स्क्रीन लॉक करने के ठीक बाद होती है, न कि केवल पासवर्ड दर्ज करने के बाद)
कैसे अतिरिक्त कदम यह पता लगाने में उपयोगी साबित हो सकता है कि इसे कैसे ठीक किया जाए?
