I created a new 17.10 VM in Parallels 13 and didn't update any packages post-installation, so I can still access the scale controls in Settings.
I'm attaching copies of ~/.config/monitors.xml before changing any settings, immediately after changing Settings > Devices > Displays > Scale to 200%, and after rebooting (which yields identical results to simply logging out and back into a session). Curiously, there are 2 Xorg servers running on a fresh installation, and this is true both before and after installing Parallels Tools in the guest VM: --- user1@testvm1:~$ ps aux | grep -i xorg root 1078 0.1 0.3 464924 15300 tty1 Sl+ 19:54 0:00 /usr/lib/xorg/Xorg vt1 -displayfd 3 -auth /run/user/121/gdm/Xauthority -background none -noreset -keeptty -verbose 3 root 1369 2.2 5.4 891936 220480 tty2 Sl+ 19:54 0:04 /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -background none -noreset -keeptty -verbose 3 --- Also attaching a screenshot of Settings > Details > About, to show the string of the video driver installed by Parallels. ** Attachment added: "Monitor config after fresh installation" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1720465/+attachment/5013913/+files/monitors.xml_fresh-install -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
