HDMI was working perfectly before but lately whenever I turn on my pc (Dell g3590), I see the ubuntu logo but after that my monitor displays no signal. My laptop's screen is broken so I don't know what's going on. so what is going on and how do I fix it.
My laptop's screen display is broken, so I usually use an external monitor and that's where I see the ubuntu logo which disappears after a minute or two loading. Also yeah it does appear to be booting up, I know the laptop works fine since I booted to another ubuntu using my usb and everything was working fine there.
OK. So you can boot fine from a USB stick and all is OK. This suggests the hard drive is bad or corrupted. Have you tried to reinstall ubuntu? I mostly use Windows, so I can't be much help. Maybe someone else has a suggestion???
