Ubuntu 20.04 guest keeps resetting DPI setting on every boot

Post by flashmozzg »

I run VBox on a high DPI 4K screen and it requires to set 200% scale in Ubuntu settings, however, after each reboot/restart Ubuntu revert to using 100% scale. Does anyone know if this could be fixed?

Another unrelated issue I'm trying to figure out is it seems that VBox overwrites /etc/resolv.conf file on every boot but doesn't set all the search domains (it uses only the first one), so I have to manually add all of them on each boot as well. It appears to be some issue with the VBox DHCP server but I don't know how to check/fix that.

Start the VM from full power off, not save-state. Run until you see the problem happen, then shut down the VM from within the VM OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.
