I am having this problem on ubuntu 18.04 on my dell precision m3800 it has built in 13inch 4k screen which is perfectly setup and scaled but i also have external 40in 4k screen on display port , this gets scaled to the same settings as the 13inch screen which is waste.
under unity i could scale each independently and it was excellent additionally my external screen now only runs at a horrible 30hz when it used to run at 60hz the internal screen runs at 60hz . xrandr doesn't give me more options I am using the nvidia driver in fulltime optimus mode with the built in -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1687246 Title: GNOME Shell should support fractional (non-integer) Hi-DPI scaling Status in Mutter: In Progress Status in Ubuntu GNOME: Triaged Status in gnome-shell package in Ubuntu: In Progress Bug description: https://trello.com/c/r12LY9iA (for 17.04 was https://trello.com/c/TvwNvXOo) --- I'm using fully updated Ubuntu GNOME 17.04. In Ubuntu Gnome, you only allow for integer scaling of things for high DPI monitors. While in theory this sounds good, on a 27 inch 4k monitor like mine, restricting it to integers is a problem. 1x is annoyingly small, and 2x is WAY too big. You need a 1.5x, and presumably to just allow most noninteger values to future proof the distribution given 8k monitors and all sorts of new and weird things coming out, like windows 10 has. Photos of the two annoying sizes are available here (it won't let me attach two files): http://i.imgur.com/vWrvZxq.jpg http://i.imgur.com/11p19k7.jpg I apologize for my photography skills in advance., you'll have to look at the ruler for scale to see the problem. Please contact me if you need any more information etc. Workaround ========== You can enable experimental fractional scaling in Ubuntu 17.10 or 18.04 LTS by running the following command in a terminal and then restarting your computer. Note that this is an experimental feature and is not fully supported by either Ubuntu or GNOME. gsettings set org.gnome.mutter experimental-features "['scale-monitor- framebuffer']" After restarting your computer, you should find additional scale options in Settings > Devices > Displays. If you change your mind and want to get back to supported status, run: gsettings reset org.gnome.mutter experimental-features To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1687246/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
