HDMI1 disconnected (normal left inverted right x axis y axis) Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384ĮDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mmĭP1 disconnected (normal left inverted right x axis y axis)ĭP2 disconnected (normal left inverted right x axis y axis) But setting that to use the nouveau display driver doesn't help either. I'm using the proprietary nvidia driver found in the "Additional Drivers" app. the second monitor is connected through the HDMI port.acer Aspire V 17 Nitro – Black Edition (Aspire VN7-792G).But as soon as the laptop turns off the screens (standby) or I reboot the machine or I unplug the cable, the second screen doesn't work anymore.Īlso, if I reinstall ubuntu-desktop, but power off the laptop with the HDMI cable plugged in, this trick doesn't seem to work. The first time I login, and the first time i plug the cable in, the second screen works without problems (dmesg still complains about WARN_ON(!wm_changed), but no more i2c i2c-1: sendbytes: NAK bailout.). If I unplug the monitor, then I run sudo apt-get install -reinstall ubuntu-desktop The same monitor, cable and laptop work in Windows. It's a fresh install of Ubuntu 14.04.3 (later also 15.10). I'm not using any special adapter, it's a straight HDMI cable. Searching the web didn't get me very far. I don't really know where to start looking to solve this problem.
