There is one brief moment where my screen reverts back to normal, when I'm shutting down, there's one brief flash of a terminal screen with white letters on a black background in a normal aspect ratio. I tried downloading Ubuntu 18.04 onto an USB and booting from USB - the stretched screen remains the same. This has happened before with previous computers and I normally just shut off the monitor and remove the hdmi cord/plug. Upon powering my laptop and monitor just now, the screen of the second monitor is stretched out.

I also tried every display option in the bios boot up menu. I recently got a second monitor for my acer laptop (using windows 10 if that matters). I've also tried updating the Intel Graphics drivers by downloading the Intel Graphics Installer and installing it: dpkg -i intel-graphics-update-tool_2.0.2_b And it's also funny that when I boot into Windows it doesn't have the exact same problem. Since it shows up on the Thinkpad start up screen before Ubuntu boots, it makes me think it's a hardware problem.but then it's funny that it appeared only after I rebooted my computer. How else can I try to solve this problem? In Ubuntu, when I try to adjust the 'Displays' property in 'System Settings', it doesn't show anything strange, it looks normal, see screenshot below. In Ubuntu, when I try to adjust the 'Displays' property in 'Settings' it says, 'Could not get screen information.' When I boot into Windows, I can see the full screen, but there's a black strip maybe 1 inch wide on the right side. I've tried sudo apt-get remove -purge xserver-xorgĠ0:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) Below is one example where I was trying to run ubuntu in recovery mode.

This occurs even before Ubuntu boots, on the Thinkpad start up screen. I updated recently, and when I restarted my computer, my screen was stretched out twice as wide. I have Ubuntu 16.04, a Lenovo T420s laptop. I'm quite puzzled about how to solve this.
