@3v1n0 I tried but can't yet confirm if the original reboot persistence bug is still happening, because it seems every time I test it an additional layer of problems occurs.
Parallels Desktop 13 still doesn't officially support Ubuntu 18.04. Ubuntu installs okay, but post-installation the VM guest tools (Parallels Tools) don't install due to breaking changes. Unfortunately those tools are necessary to enable the full host monitor resolution (2880x1800 in my case for my MacBook Pro) within the Ubuntu guest VM, and without the VM guest tools the Ubuntu VM is stuck with 800x600. The relevant Parallels support thread is here: https://forum.parallels.com/threads/parallels-support-for- ubuntu-18-04-lts.344488/ In that thread this third party workaround was mentioned: https://gist.github.com/rudolfratusinski/a4d9e3caff11a4d9d81d2e84abc9afbf Luckily using that workaround I was able to get Parallels Tools installed successfully, but since that's not an official fix I'm not confident all of the tools are fully working. I rebooted the Ubuntu VM and it detected and enabled the full 2880x1880 resolution of my host machine, finally! Then I opened Settings > Devices > Displays, but the HiDPI scaling controls are missing entirely. This is similar to what happened in the Ubuntu 17.10 guest VM in my comment #7 above, except this time the scaling controls are missing on a fresh installation of 18.04 without having yet performed any additional Ubuntu software updates. Even after installing all current Ubuntu updates and rebooting, the scaling controls are still missing. Also perhaps worth mentioning is that under Parallels Desktop 13 the default Ubuntu 18.04 GNOME session continues to use the X.org backend instead of Wayland, just as under 17.10 (there are two instances of the X server running, one on vt1 serving the GNOME greeter, and one on vt2 serving the desktop session). I suspect this is due to Parallels' custom display driver, which identifies itself on my machine as "Parallels using AMD Radeon pro 555 opengl engine". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720465 Title: HiDPI scaling does not hold across reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1720465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
