QCAD not opening after install on Ubuntu 20

Post by crashlandon » Sun Nov 22, 2020 2:47 pm

After installing qcad-3.25.2-trial-linux-x86_64.run on Ubuntu 20.04.1, and running QCAD, the GUI is not coming up. The processor grinds away for maybe 30 seconds, then drops to idle, and the GUI does not come up. Seems to be QT related, but couldn't find a previous post that seemed to reflect this case.

Here's the start of the output:

Code: Select all

You could try the QT 5.14 install, it's what I run in Mint 20
