Ubuntu 20.04 LTS on Lenovo IdeaPad Flex 5 14" 81x20005us

Lenovo IdeaPad Flex 5 14" 81x20005us 


I'll keep this short, this laptop is a buy.
At the time of this post, it goes for $599 on Amazon

Out of the box almost everything works. After installing Ubuntu 20.04 LTS, everything works except for the HDMI port. I think this has to do with the AMD AGPU and a driver is probably needed. I'll follow up with the fix once I have one if this is a software issue. 

Other than that, this laptop is a buy. I didn't bother booting up into windows. I booted Ubuntu from a USB stick and installed it with secure boot and updated the MOK without issues.


  • USB-C Charging 65W adapter included
  • 2 in 1 
  • Backlit Lenovo Keyboard
  • AMD Ryzen 4500U 6 Core CPU
  • 16GB RAM (Not Upgradeable)
  • NVME SSD 256GB (Upgradeable)
  • TouchScreen works out of the box in Ubuntu 20.04
  • Web Camera (works with boltgolt/howdy facial unlock tool, I don't think it's IR)
  • 2 X USB A 3.0 Ports
  • SD card slot
  • Glossy screen and bright enough for me
  • Comes with Stylus
  • Speakers are loud, good for YouTube Watching
  • Good amount of screen real estate
  • Fans quiet, near silent with Chrome open and playing YouTube in the backgroun
  • Plastic material has a rough feel and grips well to my wrist
  • Bezel around the screen is thin and not noticeable at all
  • Performance is great and 6 cores and 16GB of ram is plenty
  • 2 in 1 functionality works well
  • In Tablet Mode, keyboard and mouse automatically disable


  • USB C port does not support Video output must use HDMI)
  • SD Card slot is half (maybe 1/4) depth so you need an adapter if you want full time slotted SD card
  • .2lbs Heavier than a surface pro 4 with Keyboard, case, pen
  • Ubuntu Screen brightness not working, screen only turns on or off using brightness control
  • Stylus uses funky usb slot holder, just put the stylus in your bag.
  • Sound doesn't have enough bass
  • The keyboard is a good size but I noticed I my right index reaches a little more than usual for the 'Y' key, this could be due to using a Surface Pro 4 and Macbook 13" (or it's just in my head).
  • Trackpad feels cheap, it's large but the clicking is loud and has a cheap click feel to it
  • Fingerprint reader is a nice touch but it should just be on the power button or someplace above the function keys
  • CPU SMT would have been nice, getting this to 12 threads would make it the ultimate buy
  • Keyboard and trackpad do not disable when in tent or movie stand mode, this is probably an Ubuntu/Linux limitation. 
  • Screen won't rotate when in Tent mode, again probably an Ubuntu/Linux limitation. 
  • Screen does not rotate to portrait mode when converting to tablet mode, again probably an Ubuntu/Linux limitation. 
  • Webcam face detection using Howdy only works in well lit rooms.
