Linux HiDPI support is in an evolving state with some applications and environments providing seamless support while others provide close to none. I wanted to share both my findings about the state of HiDPI in each DE and some tips for how to improve usability in each environment on a high resolution screen. For all the other Desktop Environments installation instructions are included for each.
The instructions were tested coming from the XFCE edition but it should be the same regardless of where you start. Budgie Budgie is a simple and intuitive desktop. Budgie scales in 1x increments up to 3x. Cinnamon scales in 1x increments up to 3x. Deepin Deepin has added support for hidpi displays in recent versions.
The scaling is manual but it is simple to use. Deepin scales in.Coreboot documentation
The window borders are very difficult to target and some UI elements do not scale. It auto-scales by default and is completely usable out of the box. Sometimes gtk application will not scale quite as well on plasma as they do on other DEs but that is relatively rare. Scaling is automatic. Application scaling works pretty well but I noticed a lot of layout issues with MATE panels and widgets when scaling was enabled.
It is worth noting that in my testing enable auto-scaling scaled a You can set Xft. An alternative solution until Deepin receives HiDPI support is to lower the resolution in the settings which is not ideal. As an alternative, you can adjust your display resolution. Yup, I will moved this to technical-issues-and-assistance:tutorials category and adding some tags….This article helps users to configure their system for High DPI display, like a 4K monitor or notebook with retina display.
DPI setting of a regular display is If you have a 27 inch 4K display resolution is xyou want to display 2 pixel width for 1 actual pixel width, the scale factor is 2. Then the DPI setting should be Increasing scale factor could make fonts and user interface bigger and sharper. However it will make the available desktop space smaller. You should balance what you want: a larger space to show four windows at the same time, or a nice and beautiful desktop.
By default, GRUB automatically detects the resolution of screen. In high DPI devices, texts of boot menu are too small. After that, boot menu will always scale up to resolution of your choice.

I am running a T with 3K monitor and all display managers seems to load as if they were 2K. I have learned to live with - annoying - bu after all it is just login. But you mention setting dpi in SDDM - I would think that setting it to something between 96 and would cause at least fonts to scale up.
Changing DPI doesnt resolve at all. Of course you can manually force setting so they look right on your screen. But then you unplug your laptop and its not right yet again. Trivial but just not good enough.Tsclient c
I think you right. Been trying for almost a year to become friends with KDE but its just not working right. Nice project but too much stuff my OCD mind cant tolerate. Install lightdm. Not true… it uses a max of M in mine, once booted. Thanks, tried that but same error persists.
Assuming then there is no fix for this and one has to live with it. There are other reasons for avoiding sddm. Switching away from sddm to lightdm fixed the problem.
It took weeks to find that, and longer for sddm to fix it.
Hmm was just wondering because I really like the look of GDM. But using LightDM now and its working very sweet and scales perfectly. Goodbye SDDM. Bit off-topic, but oh well.
It only uses This topic was automatically closed 30 days after the last reply. New replies are no longer allowed. Does anybody have the same problem or a fix for this? If it works better, then you can uninstall sddm. Ah brilliant. Can you also use GDM? Why would you want to? Lightdm uses around 4M in my machine.

It might be that changes in some other package cause the problem, as I upgraded quite a few of them, but since this is sddm which is not functioning properly now, I think it's fair to report this here.
I have same issue in 0. Have just installed sddm This is completely broken on my deployment as well. We had a good solution with -dpi and now this is broken as well. The -dpi option also still has an effect but it seems to be applied in an unsupported manner. The layout just feels like some elements are scaled and othesr are not and the effect is a container in which you try to fit elements that are too big for it. I have tried many suggestions, e.
It would seem that, at least in my case, the Nvidia does not take scaling or panning, etc. The system already knows what the details of the monitors are, but it does not really matter. This just turns off the external HDMI monitor for the login screen ONLY and uses the 96 dpi setting for the OS and desktop to get the correct scaling -- once again, the system knows the details of your monitors i.
A potential fix would exist if you could set the DPI for the login screen, but then convert back to 96dpi before entering the desktop -- by I have not figured out how to do that -- I thought that Xstop sounded like a logical place but it made no difference.

There is no [X11] or [Wayland] section in my sddm. How can I correctly add the above line to the sddm. You can then generate a sample sddm. You can then modify the relevant lines such as themes, cursors and finally tag your dpi settings to the ServerArguments line. But, afaik this only affects font scaling. A better solution would be to ensure Xorg is configured correctly, specifically in the monitor section you need to make sure either your dpi is specified there or that the correct dimensions mm of your monitor are specified.
Xorg can then correctly calculate your DPI. This command will not work as the redirection is done as a regular user, and you will get a permission denied error. It should be something like this:. Atom topic feed.How to read wechat backup file on pc
