I have a Raspberry Pi 3B+ and I just installed xrdp on it. I wanted to do this so I can do some ROS projects. But just after using RDP to log in to the Pi, I was welcomed with a painfully slow desktop. I have plenty of internet speed/bandwidth. My Picamera that I have attached to the Pi is also very slow and I am getting very low FPS. Is there anything I can do to fix all of this?


  • Raspberry Pi 3B+
  • Picamera with Ribbon
  • Proper Cooling(heatsinks, fans)
  • Good internet speed(20Mbps Download,
  • Raspberry OS with Latest Updates
  • how big is your sd card? Maybe you can try one with more space Commented May 11, 2021 at 17:47
  • It is 32GB and it is not that full.....I think. Commented May 11, 2021 at 17:50
  • should be fine; are you having the same issue when you login to the pi directly without using xrdp? Commented May 11, 2021 at 18:15

I had the same problem. Try editing /usr/bin/startlxde-pi and set TOTAL_MEM=ge20480. That solved the problem for me.
