.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 0 I had a dummy output issue on my Lenovo T470S (model 20HFCTO1WW) but just today there was an auto update by Ubuntu that was reportedly related to Lenovo Thinkpad and the sound was fixed, however, only for the laptop speakers and not when the headphones jack is plugged in. How do I get the sound to come out my headphones? sound headphones share | improve this question asked yesterday amphibient amphibient 602 3 8 18 ...

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 0 I have KUbuntu 18.04.2 LTS. graphics card (lshw): GM107 [GeForce GTX 750 Ti] driver: nvidia 390.116 4k monitor: BenQ EL2870U The monitor is connected via HDMI. But it is the same with DVI. If I connect the monitor to a different PC (same OS) then the tty is normal (black). If I connect a different monitor to the first PC then the tty is normal too. Maybe it's related to the 4K resolution? See photo. tty share | improve this question edited yesterday ...
