About

Xpra is known as "screen for X" : its seamless mode allows you to run X11 programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine(s), without losing any state. Effectively giving you remote access to individual graphical applications.
It can also be used to access existing desktop sessions and start remote desktop sessions.

Xpra is open-source (GPLv2+) with clients available for many supported platforms and the server includes a built-in HTML5 client.
Xpra is usable over a wide variety of network protocols and does its best to adapt to any network conditions.

Xpra forwards and synchronizes many extra desktop features which allows remote applications to integrate transparently into the client's desktop environment: audio input and output, printers, clipboard, system trays, notifications, webcams, etc

It can also open documents and URLs remotely, display high bit depth content and it will try honour the display's DPI.

Installation

Official stable downloads

All the packages are signed. There are also beta builds available.
For more information, see xpra downloads

Build from source

git clone https://github.com/Xpra-org/xpra; cd xpra
python3 ./setup.py install

For more details, see building from source.

Usage

Seamless Mode

To start an xterm on a remote host and display it locally:

xpra start ssh://[email protected]/ --start=xterm

(both xpra and xterm must be installed on HOST).
For more examples, see usage.

Shadow

To view an existing desktop session running on a remote host:

xpra shadow ssh://[email protected]/

Network Access

Xpra servers can support many different types of connections using a single TCP port: SSL, SSH, (secure) http / websockets, RFB, etc..
Connections can be secured using encryption and many authentication modules.
Sessions can be automatically announced on LANs using multicast DNS so that clients can connect more easily using a GUI (ie: xpra mdns-gui).
Its flexible proxy server can be used as a relay or front end for multiple server sessions.

    Follow up from #400, #669 - related to #835.

    • would be nice to share more code between the client and server
    • handle the sound sequence mechanism for "microphone" just like we do for "speaker"
    • use a cython or ctypes wrapper for accessing the pulse properties rather execing a subprocess
    • avoid the osx pool autorelease warnings?
    • setup process tagging in subprocess only?
    • allow us to use python3 / gstreamer 1.0 in the subprocess from a python2 caller (requires execing a process to get the list of codecs supported..)

    python3 and gtk3 support

    Issue migrated from trac ticket # 90

    component: core | priority: major | resolution: fixed

    2012-03-27 08:53:09: antoine created the issue

    Makes sense to bundle this together since python3 is only really supported with gtk3 and vice versa.

    Main work items:

    • backwards compatible python3 changes (via 2to3 mostly), most already done in r618, r619, r620, r621 and r622
    • python3 strings: changes need testing on python2.5, also need to ensure that calling encode(..) and decode(..) does not adversely affect performance
    • for other non-backwards compatible python3 changes, find a way to run 2to3 during build so we can keep a unified source tree in python2 format. (main issue here: catch exception syntax change)
    • gtk3 imports have moved and now require annotation to silence pydev lint
    • gtk3 methods on gtk.Window have changed, client.py will need to provide wrapper methods:
      • gdk.get_default_root_window().get_pointer() (removed)
      • gdk.get_default_root_window().get_size() (removed)
      • gtk.Window.__init__(win, wintype) (removed: no arg constructor now)
      • window.set_geometry_hints(...) (signature changed)
      • window.flags() (removed - must call get_$FLAGNAME)
      • window.window.set_cursor(..) (renamed to window.override_cursor?)
      • window.window.invalidate_rect (now window.queue_draw_area)
      • do_expose_event(event) is now do_draw(context)
      • window.window.get_geometry (removed, must now call get_position() and get_size()?)
      • constants have moved
      • gdk.keymap_get_default (removed?)
      • gdk.Cursor can no longer use pixbuf..
      • ...
    • gtk3 removed GdkPixmap and GdkImage, we're supposed to be using cairo but cairo.ImageSurface.create_for_data is not implemented in pycairo and there are no alternatives (ouch!)
    • PIL (Python Imaging Library) is not available on python3 (so we can't use that to fix cairo either)

    As discussed here on the mailing list

    We need to calculate the client's screen dimensions and pass it to the server so that the Xvfb uses the same dimensions.

    The --dpi option of xrandr actually computes dimensions from the resolution and dpi.

  • Focus issue with mouse on osx client

    Focus issue with mouse on osx client

    Issue migrated from trac ticket # 469

    component: client | priority: major | resolution: wontfix | keywords: osx focus

    2013-12-11 02:15:18: afarr created the issue

    With osx client 4905 mouse cursor focus seems to become confused when there is a single click on an xpra session window overlapping a second xpra session window.

    Testing with windows client (0.11.0r4903) against a fedora 19 server (0.11.0r4904) the erratic cursor/focus behavior does not occur.

    In the edited logs that I included in #438 (I'll load those logs into this ticket when I get a chance), there is an initial focus on window 55 (first drawn on line 31 of the log, comes into focus line 139), followed by a focus shift to window 82 (first drawn on line 43, comes into initial focus on line 157, I think)... then there follows what I assume are indications of mouse-wheel scrolling events occurring on window 55 (lines 174 on). That is the 'event'. The logs aren't clear that focus shifted to window 82, from what I can tell, but what I did was to click on 55, then click 82, then click 82 again on a portion of the window which, once 82 'rose' to focus, was now overlapping 55. From then on, I never clicked on window 55 again, nor did I scroll the mouse off of window 82. From the point of line 157 in the log on, my cursor remained hovering over window 82 ... but the mouse scrolling events all seem to register on the lower window (55) despite the appearance of focus being on window 82. Testing this with xterms showed that the keystrokes would register on the apparently focused window, but also that clicking on a portion of an 'upper' window (with apparent focus) which was 'above' a window space with a link would trigger the link 'through' the apparent-focus window.

    component: encodings | priority: major | resolution: fixed

    2018-11-01 16:03:47: nathan_lstc created the issue

    Unless I run xpra with only h264 enabled,

    /usr/bin/python2 /usr/bin/xpra start -d encoder --start=xterm --no-daemon --video-encoders=nvenc --encodings=h264 :57

    I can observe from the debug data that very few frames are actually rendered using NVENC even when I have h264 selected from the UI. When I run it using the above command, it works wonderfully. I'm using r20858 on CentOS7 with VirtualGL on the server and an r20882 client on windows. The driver is 390.87. I'm using a C2075 for render and a K20c for encode.

    I do not think the problem has much to do with my hardware or reversion because I'm having this trouble on all of my configurations including a brand-new new computer (the other one is pretty old) with a GTX 1060 running release 2.3.4 server with release 2.4 client.

  • better sub-window encoding: detect regions and use sub video encoder

    better sub-window encoding: detect regions and use sub video encoder

    Issue migrated from trac ticket # 410

    component: core | priority: critical | resolution: fixed

    2013-08-09 07:19:24: totaam created the issue

    If you have a large window but only a fraction of that window changes we waste a lot resources. We currently create a video encoder for the whole window and waste a fair bit of time capturing, csc-ing, encoding, (sending), decoding and displaying regions of the screen that have not changed at all (and we know they haven't) [[BR]] We have the "small region" code, which deals with small-ish regions by sending them using another encoding (usually rgb or png/jpeg) but it has its limits: it does not use a video encoder and is limited in size. [[BR]] We should keep track of the damage areas in more detail, including their location and size (easy). Then we can detect regions of the screen that update often (easy-ish) and create a sub video encoder just for those (harder). This could even work when the region is moving, as long as its size stays the same. This is negated somewhat by the fact that when we send the whole window (because of other updates), it will include this region - unless we purposedly blank it out before compression and ask the client to re-assemble the two before displaying the result (hard).

    An even better solution to this would be #509 or #510, as this would give us the video area precisely everytime, even before it gets converted to RGB pixels.

    GL acceleration for client rendering

    Issue migrated from trac ticket # 147

    component: client | priority: major | resolution: fixed | keywords: GL

    2012-06-16 07:52:48: antoine created the issue

    (remaining) tasks:

    • provide a GL client window alternative to the standard gtk window, so OpenGL can take care of colourspace conversion, done in r922
    • urgent: fix vpx (ahuillet)
    • support all encodings (ie: mmap, jpeg and png)
    • do_expose_event isn't called automatically - fix it
    • fallback to non-GL rendering when PyOpenGL is not installed, or when the GL driver is blacklisted (or not whitelisted)
    • win32 build: we need to document how to build everything from scratch

    Changes required from commit r922:

    • whitespace cleanup
    • remove wildcard imports
    • remove unused variables
    • constify GL command string
    • do not use SystemExit
    • why does this crash python??:
    python -c "from OpenGL.GL import glGetString, GL_VERSION; glGetString(GL_VERSION)"
    • remove duplicated window backing code: separate GL (backing) from window code - and re-use backing (super)class if needed. GLWindowBacking is not used??
    • use booleans and not integers (ie: vtxarrays - not used?)
    • use_openGL_CSC is hardcoded, make it a switch? Needs testing too.
    • self.current_mode and self.textures, need documenting more clearly, and initializing in constructor?
    • restore nogil for decompress_image_to_rgb: csc_image_yuv2rgb does not need the gil
    • run automated tests to compare with more scenarios

    Contingency plan: we can disable the opengl code if this proves unstable or problematic.

    Note:

    • with local connections, it might even be possible for the server to render directly to the client window? (even faster than mmap)

    Paste from windows not working in 3.1.3 client (server 3.1.2): NameError: name 'ellipsizer' is not defined

    Hi there,

    I recently updated my MS WIndows Xpra client from 2.* to 3.1.3 and have noticed that pasting from the windows clipboard is timing out, then failing (eventually pasting something from one of the X selections).

    Steps to reproduce:

    1. server xpra start :1011 --start=xterm
    2. client xpra_cmd attach ssh://[email protected]/:1011
    3. in windows open notepad and type 'test'. copy 'test' text to clipboard with "ctrl-c"
    4. in the xterm, press middle click

    expect: paste "test" to the xterm actual: xterm hangs for a few seconds, nothing is pasted.

  • Log files should be moved out of /run/user/<UID>/xpra

    Log files should be moved out of /run/user//xpra

    Is your feature request related to a problem? Please describe.

    Log files (Xorg.log, server.log) need to be moved from /run/user/<UID>//XDG_RUNTIME_DIR directories. Suitable locations could user based directories (e.g. XDG_DATA_HOME) or standard /var/log directories.

    The filesystem under /run/user/ is tmpfs. It is situated in RAM. Use recommendations for that directory include temporary storage of PIDs, sockets, etc, session information, configuration files - all with consideration to be small.

    LOG files belong on the opposite side of the size spectrum. Occasionally they tend to grow fast and for that reason often are placed on separate partitions altogether.

    Describe the solution you'd like

    Possible suitable LOG location candidates

    • XDG_DATA_HOME
    • XDG_CACHE_HOME
    • /var/log directories

    Alternatively LOG file location could be configurable via cmd arguments or configuration file(s).

    Describe alternatives you've considered

  • Xpra opens windows as tabs

    Xpra opens windows as tabs

    Describe the bug Not sure if it's a bug or not. But I've searched a lot and I haven't seen anyone (or the documentation) mentioning this. I use Xpra 4.4 on a remote headless Linux server and my local macOS laptop to have the GUIs of the apps running on Docker containers of the Linux server shown on my macOS laptop, even with streaming audio and OpenGL. Everything works perfectly, but there is an issue that's been bothering me a lot. I run Xpra in the seamless mode, and all windows are shown as tabs of a single window on macOS. Then, I need to detach the tab into a new window manually:

    tg_image_1906475866

    If it's not clear, what I want is to have each window opened as a separate window, not a new tab. I already have some application running, and I develop some code that I need to respawn regularly, which would be frustrating as each time I have to switch to that tab (for that window) which also mistakenly inherits the size of the previous window (tab) that is already open.

    As a side, I have found that the binaries released for macOS can not be run due to an issue with the libcrypto shipped with Xpra. FYI, I resolve this issue by replacing those files with the libcrypto and libssl installed by Homebrew. So, at least this one is a bug!

    To Reproduce Steps to reproduce the behavior:

    1. Server: xpra start --daemon=yes :9898
    2. Client: xpra attach ssh:[email protected]:9898 --encoding=h264
    3. Action: Opening any [unrelated] applications
    4. Effect: All windows are shown as new tabs. Need an option to override this so that any window would be result on a new window on the client.

    System Information (please complete the following information):

    • Server OS: Headless Ubuntu 22.04.1 LTS (with Ubuntu 20.04 Docker images)
    • Client OS: macOS Ventura 13.0.1
    • Xpra Server Version: v4.4.3-r0
    • Xpra Client Version v4.4-r0

  • Programs are not recognized as being from different applications in a Wayland session

    Programs are not recognized as being from different applications in a Wayland session

    Describe the bug When using xpra in a wayland session with KWin compositor, all xpra windows get grouped under the same taskbar entry and all windows have the xpra icon. It seems that some window class or the wayland equivalent is set to xpra and not to the window class of the forwarded program (coming from a virtual X11 server on the server-side).

    To Reproduce

    1. Server: xpra start :10
    2. Client: xpra attach ssh://server/10 (on wayland)
    3. Action: Open some windows from different applications
    4. Effect: All windows are grouped as if they were from the same applications and all windows have the xpra icon, so wayland probably treats xpra windows as a single application instead of forwarded windows from different applications.

    System Information (please complete the following information):

    • Server OS: Debian bullseyes
    • Client OS: Debian bookworm
    • Xpra Server Version: v4.4.3-r0
    • Xpra Client Version: v5.0-r32356
