[Bug 1528319] Re: Scaling factors for HiDPI on multiple monitors
I'm on an iMac, so I want to make use of my Retina (hj-dpi) screen, while also using external screens that are not hi-dpi. I can confirm no good X11 support for separate dpis per screen. I was able to mess around with xrandr, but I got ghosting on my mouse cursor that I could not resolve. Possibly I could have hand-configured an X config for my particular screens, but seems like a lot of work and I don't want to hard-code my screens. The iMac screen doesn't work with all the resolutions selectable. In fact, my realistic choices were basically either: 1) Full resolution with 200% scaling, and no usable second screen 2) 1/2 resolution with 100% scaling and usable second screen I settled for '2'. However, I read this issue and did see Wayland supported it. So I: 1) Logged in with Wayland 2) Ran gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']" 3) Logged out (necessary) 4) Changed my dpis per screen in Display settings It works reasonably well. Gnome apps are crisp on my Retina screens, other apps are blurry due to presumable up-scaling of low-dpi rendering to go onto the larger canvas. Unfortunately of course Ubuntu has made Wayland non-default. I hope it can become default again and all the issues with it (network protocol, native app support) can be resolved, as I do think X11 is dated at this point. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1528319 Title: Scaling factors for HiDPI on multiple monitors To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1528319/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1528319] Re: Scaling factors for HiDPI on multiple monitors
It looks like it's working now in Ubuntu 17.10! In the display settings you can set the resolution and the scaling individually per monitor if you are using Wayland. You might have to turn on fractional scaling (see http://www.omgubuntu.co.uk/2017/09/enable-fractional-scaling-gnome- linux). If I set my laptop monitor to 3840 x 2160 and 175% scaling and the external monitor to 1920x1080 and 100% scaling, xrandr says: Screen 0: minimum 320 x 200, current 2192 x 2313, maximum 8192 x 8192 XWAYLAND0 connected 2192x1233+0+1080 (normal left inverted right x axis y axis) 350mm x 190mm 2192x1233 59.89*+ XWAYLAND4 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 530mm x 300mm 1920x1080 59.96*+ I am seeing a flickering white line just above the gnome top bar (and it flickers on the right hand side), though. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1528319 Title: Scaling factors for HiDPI on multiple monitors To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1528319/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1528319] Re: Scaling factors for HiDPI on multiple monitors
@Kai: You can set per-monitor scaling by setting org.gnome.desktop.interface scaling-factor to zero, and then Wayland figures out the scaling automatically. But it only works for apps that support Wayland directly (like nautilus), not for apps that run under XWayland (like chrome and firefox and most other apps as well), so it's a bit pointless at the moment. There's some info here: https://askubuntu.com/questions/875832/how-to-set-per-monitor-scaling- on-wayland The page https://wiki.gnome.org/HowDoI/HiDpi talks about HiDPI support via the org.gnome.settings-daemon.plugins.xsettings overrides setting. I think it says Wayland detects monitors above a certain resolution as HiDPI and applies the override scaling factor you set (eg of 2) just to those monitors, but I haven't tried it. (My guess is it also doesn't work with XWayland apps). And https://bbs.archlinux.org/viewtopic.php?id=221742 discusses issues when trying to use this setting. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1528319 Title: Scaling factors for HiDPI on multiple monitors To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1528319/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
