The new implementation does work for updating the settings; however, it's glitchy.
What I mean by that is when one has the settings set for 200% scaling, reboots the VM and then logs back in (at least in VMWare -- haven't tested elsewhere) the scaling for text is at 100%; however, icons appear to be scaled. In order to get the whole desktop experience working correctly the following sequence needs to be followed: 1. set scaling for the display to 100%. click apply. Click keep settings. 1.a. Repeat #1 because you need to do it with more feeling. 2. set the desktop to 200%. 2.a. Repeat #2 because, once again, more feeling is required to get the setting to stick than the initial click of 'keep settings'. 3. Close and re-open any applications that utilize the DPI scaling functionality. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1709667 Title: Missing desktop scaling slider in system settings Status in gnome-control-center package in Ubuntu: Incomplete Bug description: When upgrading from ubuntu 17.04 to 17.10 (obviously new window manager) ... there is no longer the ability to configure the HiDPI scaling within the window manager. This may be an intentional regression or simply something that got passed by. But I find this configuration option to be very useful when working on a Lenovo P70 w/ 17" 4k monitor (which neds 2x DPI scaling) and also when switching back to my multiple-monitor configuration (which doesn't need any scaling). This is a piece of functionality I use on a regular basis that is now lost.
