Can't say with absolute certainty but, looks like a hardware issue to me. If it's not, I'd be interested to know what caused it.
After I woke up I saw my laptop display is showing misaligned screen.I have no idea whether I rollover on my laptop while sleeping. Display as shown in my video recorded link [URL] In order to find hardware or software issue I connect hdmi cable and view it in desktop but it shows screen as shown in my captured picture Desktop Picture. [IMAGE]   The above screen shows only my Ubuntu desktop wallpaper it's not showing my apps and other things.   What problem it's hardware or software? I updated, upgraded by running '''sudo apt update''', '''sudo apt upgrade'''.Issue Still persist.
