I already tried that, it V4.1.5 worked with both Ubuntu 18.04 and 20.04. I put in an earlier comment about this.

When the upgrade was run my external HDMI monitor was plugged in, after the update, when I reboot, the internal monitor shows the beginning of the boot process (I deactivated 'silent splash' by editing grub.cfg) then it switches to the HDMI monitor and the internal monitor goes dark. I can also get the tty consoles on the external monitor but not on the internal monitor. In MATE it was a real problem because the panel is apparently still on the invisible part of the desktop; I used a tty to install gnome, then I could get the display settings by right-clicking on the desktop, and setting the monitors to mirror, so I can reach applications, etc. Computer is a Dell Inspiron 3275 AIO with touch screen and Intel on-board video, I think. I had no problems with Ubuntu 18.04 with MATE. The problem seems to be similar to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874194 but sort of the reverse, in that the internal monitor is the problem.
