I have two identical HP monitors that both can handle 1920x1080 resolution connected to a basic HP SlimDesktop model 290-p0043w with a basic Intel® UHD Graphics 610 GPU.

Ubuntu 32-bit, dual monitor very slow
je flag

Older 32-bit laptop running 18.04.

When I plug in an external VGA monitor it slows down abysmally, as in 20+seconds between keystrokes. If I unplug the monitor it works fine again.

External shows the background fine and cursor is normal speed. Everything else is dead slow. Tried several monitors same result.

How can I fix this?

Display problem connected via VGA Splitter

I have one monitor with 1366x768 resolution and two CPUs(one Windows System and one Ubuntu System). I am using VGA splitter to render two CPUs. But I am facing few problems :

  • Every time I switch display from splitter , my resolution resets to 1024 x 768. Then manually I have to set it to 1366 x 768 using xrandr.

Adding Multiple Monitors to Ubuntu
cn flag

I currently have my system setup with Ubuntu 20.04. I have one HDMI port, where I am able to successfully add an additional monitor. I would like to add two more additional monitors (three total). Does any one have a hardware recommendation for either a HDMI to USB adapter or a VGA to USB adapter that works well with Ubuntu?
