Is there a way to get HiDPI from X programs, or at least a small-but-crisp rendering?

My current (only) target is spacemacs-docker, and running it right now gives me correctly sized but very blurry text. I imagine it is rendered on a lower resolution and then upscaled.

I've tried changing XORG_DPI (env), XPRA_DPI (env), desktop-scaling (xpra.conf), but I'm limited by my lack of knowledge on both Xpra and X11.

The current workaround is to disable the system "2x" scaling, so that Xpra receives the correct screen size (4k) and renders the output accordingly. It is indeed very small, but I can increase the font size and have normal-sized, crisp text.)

Please let me know if you'd like me to check/test something that I've missed.

This is an absurdly amazing tool! Thank you very much!

aisamu commented 6 years ago

Here's spacemacs rendered through x11-bridge (left) vs native (right).

JAremko commented 6 years ago

@aisamu Besides setting this and that vars via docker envs dno :thinking: Mb try fiddling with Xpra client settings.

aisamu commented 6 years ago

Yup, that's exactly what I've tried fiddling with! e.g. setting both mentioned vars to 192 gives me the same result, with the following output:

Note that the advertised screen sizes are what OS X wants, not the true panel size. Both are actually 2x that.

I've also tried (all are active now):

// filename:linenumber
// Changes

/Applications/Xpra.app/Contents/Resources/etc/xpra/conf.d/05_features.conf:45
env = XPRA_DEFAULT_VFB_RESOLUTION=3840x2160

video-scaling = off
dpi = 192

/Applications/Xpra.app/Contents/Resources/etc/xpra/conf.d/40_client.conf:65
desktop-scaling = off

When I turn of the 2x scaling on the OS, I get the correct output on Xpra, with the desired 1x1 pixel mapping. This is the output during the change:

The reason I cannot go with this workaround is that it makes everything else on the system incredibly small.

aisamu commented 6 years ago

I forgot to mention: setting desktop-scaling to 50% gives me the correct screen size for monitor 2 from Xpra's server logs, as well as the expected (smaller) font size on Spacemacs on my screen, but the pixel density doesn't increase (making it unreadable). :/

JAremko commented 6 years ago

@aisamu You can try using XQuartz instead of Xpra it will give you better performance and probably solve the problem.

aisamu commented 6 years ago

Good call! Tried it and unfortunately got the same results 😞.

Is there a way to advertise a forced, fake screen size (2x) to Xpra? Since it works when I turn off OSX's system scaling, I still have hope!

JAremko commented 6 years ago

@aisamu Hmm. I think you should ask at https://www.xpra.org/ they helped me a ton when I had feature request, found bugs.

@aisamu Btw can you try XQuartz and Xpra with something like Firefox? Just to make sure that we aren't searching for a problem in a wrong place.

https://bugs.freedesktop.org/show_bug.cgi?id=92777 :thinking:

aisamu commented 6 years ago

Tested Firefox with XQuartz, same behavior. (followed this: https://fredrikaverpil.github.io/2016/07/31/docker-for-mac-and-gui-applications/) Correct size (consistent with the OS), but extra-large pixels. Turning off system scaling "fixes" it as well (1-to-1 pixel mapping, everything becomes small).

Firefox with Xpra is interesting. With the DPI flags set to 192, FF renders as if it were on a HiDPI display, but at twice the size! Turning down the desktop-scaling to 0.5 brings it back to the correct size, but the DPI is reduced as well. So close! Firefox with Xpra and no DPI flags is just like the others.

aisamu commented 6 years ago

Firefox with Xpra using the web client behaves as the local client with DPI flags set: rendered as a HiDPI app, but at twice the size. (even with the DPI flags unset)

aisamu commented 6 years ago

I've asked on xpra's IRC channel and I was told the version we're using (2.0.1) is a bit old and unsupported. They've also asked if we're using the patched dummy driver, but I really couldn't answer with certainty. (they mentioned that https://xpra.org/trac/wiki/Xdummy should contain the patches)

JAremko commented 6 years ago

@aisamu We use dummy from Alpine repo https://pkgs.alpinelinux.org/package/edge/main/ppc64le/xf86-video-dummy

JAremko commented 6 years ago

(2.0.1) is a bit old and unsupported.

You can try build Xpra with a different version https://github.com/JAremko/docker-x11-bridge/blob/master/Dockerfile#L6 and submit PR if it works. You can figure out what is the latest one from by looking here https://www.xpra.org/src/

aisamu commented 6 years ago

I'm trying to build it with version 2.3, but the RUN command fails with returned a non-zero code: 3

JAremko commented 6 years ago

@aisamu Usually it means that Xpra changed its dependencies and we need to add new packages and stuff.

Look into build log :wink:

Yeah this (EE) parse_vt_settings: Cannot open /dev/tty0 (No such file or directory) doesn't look good. Having same problem.

Debian and Ubuntu have xserver-xorg-input-void package that may help... We can try replacing Alpine with Ubuntu.

I'll probably try building Xpra to figure out when it broke.

JAremko commented 6 years ago

@aisamu Looks like I managed to fix it and update to the latest version :shipit:

aisamu commented 6 years ago

Tested it, thank you so much! Still no luck, though :( Here are the screenshots of the HTML Client, the Xpra Client (with scaling off) and the Native app. The server was started with -e XORG_DPI=192 -e XPRA_DPI=192 -e XPRA_HTML_DPI=192

We're still getting these warnings:

2018-07-20 18:59:53,354 DPI set to 42 x 25 (wanted 72 x 72)
2018-07-20 18:59:53,354  you may experience scaling problems, such as huge or small fonts, etc
2018-07-20 18:59:53,354  to fix this issue, try the dpi switch, or use a patched Xorg dummy driver

JAremko commented 6 years ago

@aisamu You can try building dummy with patches from https://xpra.org/trac/wiki/Xdummy#Status but it will require coding in C :thinking:

It may help you https://git.alpinelinux.org/cgit/aports/tree/main/xf86-video-dummy/APKBUILD

aisamu commented 6 years ago

:sob:

JAremko commented 6 years ago

Now we use patched dummy.

@aisamu When it finishes building you can try again with the new image.

JAremko commented 6 years ago

@aisamu Added another update - removed stuff that seems to be no longer needed. Now it needs good testing :shipit:

aisamu commented 6 years ago

Oh my, you're fast!

Done testing, fiddling with all the parameters listed before. It's not working yet, but we've got some new behavior!

Xpra logs

We no longer get the dpi warning, but it shows 72dpi even with all the env vars on the server and the parameters on my local .conf files set to 192.

If I set the desktop scaling to 50% I get the correct screen size (but the pixels don't shrink accordingly, so the image gets effectively worse):

Firefox

Firefox, when both the server and client are forcing 192 DPI, renders itself as a HIDPI app - but at twice the "correct" size, since the effective DPI is not correct. If I then scale it back with desktop-scaling I loose the added pixels.

Scaling off

After setting scale to 50%

(Poor quality only apparent if you click the thumbnail)

Emacs

Emacs behaves the same as before

JAremko commented 6 years ago

@aisamu What Xpra ppl saying about it? :thinking:

JAremko commented 6 years ago

We use latest Xpra with latest dummy patched with all 3 xpra patches (without conflicts)

JAremko commented 6 years ago

@aisamu The only somewhat reasonable thing I can think about at this point is fiddling with /etc/xpra/xorg.conf
You can mount modified version.

Mb try removing/adding some resolutions to force it into hiDPI mode. Also try removing this section - it is at the end of the /etc/xpra/xorg.conf file :thinking:

aisamu commented 6 years ago

I had some free time today to test some of the parameters with your latest version:

--desktop-scaling=on|off|auto|value
                  desktop−size - the scaling will be enabled and the server will render to the given size. ie: 1600x1200

@aisamu So if you use default Xpra config it doesn't start... :thinking:

JAremko commented 6 years ago

Mb there is something interesting in /tmp/xdg/xpra/Xorg.:14.log

aisamu commented 6 years ago

Tried it again with the contents of the link and got the same result :/

JAremko commented 6 years ago

@aisamu That's probably a good thing. There is a real probability that this Load "fb" makes Xorg not actually use dummy while Xpra thinks it does. Just a hunch :thinking:

@aisamu And if you use Load "fb" does it try to LoadModule: "dummy" ?

@aisamu [ 1188.930] (==) DUMMY(0): DPI set to (96, 96) interesting. Have you actually set it to 96 ?

aisamu commented 6 years ago

No! I ask for 192 everywhere that I could think of... Server is started with:

-e XORG_DPI="192" \
-e XPRA_DPI="192" \
-e XPRA_HTML_DPI="192" \

Client is started with:

Xpra attach ... --dpi=192

And the relevant client conf.d/ file also has dpi=192

JAremko commented 6 years ago

May be if you start Xorg from Xpra like in https://xpra.org/trac/wiki/Xdummy it will help :confused:

xpra --xvfb="Xorg <xorg_configs>" \
    start :14

Here's how we start Xorg (you can comment it out or set START_XORG to something else then "yes") https://github.com/JAremko/docker-x11-bridge/blob/master/bin/run#L44

And here's how we start Xpra (add --xvfb stuff here) https://github.com/JAremko/docker-x11-bridge/blob/master/bin/tcp_m

Did some asking about fb thingy https://unix.stackexchange.com/a/460553/145842

totaam commented 6 years ago

Note that the advertised screen sizes are what OS X wants, not the true panel size. Both are actually 2x that.

If the OS is lying to xpra, then xpra doesn't stand a chance to paint things with the desired geometry.

env = XPRA_DEFAULT_VFB_RESOLUTION=3840x2160

FYI: this is only useful for applications that try to calculate their own DPI based on the screen geometry. And only for application started before the client connects.

video-scaling = off

This only affects video encoders. Unless your application is refreshing the screen at 10fps or more, this won't make any difference.

When I turn of the 2x scaling on the OS, I get the correct output on Xpra, with the desired 1x1 pixel mapping. The reason I cannot go with this workaround is that it makes everything else on the system incredibly small.

Sounds like it is the other applications that need to adapt properly to the DPI, not xpra.

Is there a way to advertise a forced, fake screen size (2x) to Xpra?

No, and even if there was one, it wouldn't help: xpra would still be painting using APIs that pretend to be a different size.

There is nothing you can do server side. The only hope is to find a way to get macos screen API to stop lying about the resolution of the monitors. Similar to what we have under MS Windows with their DPI Aware / awareness settings. Xpra's "Helpers/GTK_info" or "Helpers/NativeGUI_info" utility scripts have to be able to get the real monitor geometry to have any hope of rendering correctly. If that's even possible and they have an API for it.

Just in case (unlikely IMO), you may want to try the macos beta builds based on the newer python3 / gtk3 toolkit: (https://xpra.org/beta/osx/ xpra macos beta builds)

aisamu commented 6 years ago

@totaam Thank you for the input!

Sounds like it is the other applications that need to adapt properly to the DPI, not xpra.

Xpra is being correctly rendered, but as a non HiDPI-aware OS X app. You can get the same behavior out of a HiDPI app by checking the "render in low resolution" flag on the app's "Get Info" (Example)

What I meant is that my end goal is to have Xpra rendering using the "real" pixels, as a HiDPI app, even if that means the underlying application will be extra-small (since there's not necessarily support on X11 or by the app).

If that's even possible and they have an API for it.

I'll keep my fingers crossed!

You may want to try the macos beta builds

Gave it a try, but it won't start :/ I'm on Yosemite (two minor versions behind), so that might be understandable.

And thanks for this great software :)
