Begin forwarded message: From: "Berdonces Bonelo, Erik" <[email protected]<mailto:[email protected]>> Subject: Re: HTML start-desktop crash Date: February 13, 2017 at 1:44:44 PM GMT+1 To: [email protected]<mailto:[email protected]> Hi again, I’m sorry but I’m not receiving any of your mails in my mailbox. I have to go to the ML archives an read the answers there. When I meant it doesn’t work is that it throws exactly the same error. And I’m not using any funny or strange configuration. It’s just a plain Ubuntu 14.04 server installed with default configuration, just install everything, enable SSH, and install xPra using the remote winswitch repo. 0.15.10-1 works as expected, but any version after this, throws the errors that I sent in the previous message. So procedure to reproduce: 1. Install Ubuntu Server x64 14.04 in VirtualBox (running in MacOS) or any server (I have already tried in both). Simple settings, just enabling SSH server to remote connect and no interface or anything needed. If you want you can install SSH manually later on yourself, but this doesn’t affect the result. No NFS, nothing strange, just a plain installation of ubuntu. 2. Update the packages and install xTerm:`sudo apt-get update && apt-get upgrade -y && apt-get install xterm` 3. Install xPra (via winswitch or deb packages): 3.1Follow the instructions in https://winswitch.org/downloads/debian-repository.html?dist_select=trusty for trusty (14.04). 3.2 I also tried the alternative alternative installing with the deb packages manually from http://xpra.org/dists/trusty/main/binary-amd64/ with dpkg and apt-get install -f (both procedures 3.1 and 3.2 result in the same error later on). I made sure to install websockify, python-xxhash, python-reencode, ffmpeg-xpra when installing deb packages manually. Usually I use the winswitch PPA repo as it’s much easier. Xpra gets installed with version 1.0.3: sturgelose@gilgamesh:~$ xpra --version xpra v1.0.3-r15051 4. Add user ubuntu to Xpra group `sudo usermod -a -G Xpra ubuntu` to avoid problems. 5. Execute `xpra start --bind-tcp=0.0.0.0:14500 --start-child=xterm` (just start a screen with xterm). There is nothing running in port 14500. You can also try with different ports, and will result the same problems. Also tried with `--html=on` option with the HTML5 client, it will happen exactly the same. And I tried different computers as clients. If the command in 5. is ran as default non root user (ubuntu user), which is part of the Xpra group (added in 4.), the server doesn’t start and the daemon ends (mostly the error I sent in previous messages): 2017-02-13 09:46:02,017 Error: failed to create socket '/home/ubuntu/.xpra/machine86ec8863-384b-4baf-af76-aadfbefd4400-0': 2017-02-13 09:46:02,017 [Errno 1] Operation not permitted: '/home/ubuntu/.xpra/machine86ec8863-384b-4baf-af76-aadfbefd4400-0' xpra initialization error: failed to create socket /home/ubuntu/.xpra/machine86ec8863-384b-4baf-af76-aadfbefd4400-0 If run the command (5.) as root user (something I’d like to avoid doing), the socket connects, but then when connecting from the client, it says it can’t find bus package (and other packages), which is installed… still you can try to connect a client but the dbus error will kill the process. _XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: server already running Initializing built-in extension Generic Event Extension Initializing built-in extension SHAPE Initializing built-in extension MIT-SHM Initializing built-in extension XInputExtension Initializing built-in extension XTEST Initializing built-in extension BIG-REQUESTS Initializing built-in extension SYNC Initializing built-in extension XKEYBOARD Initializing built-in extension XC-MISC Initializing built-in extension SECURITY Initializing built-in extension XINERAMA Initializing built-in extension XFIXES Initializing built-in extension RENDER Initializing built-in extension RANDR Initializing built-in extension COMPOSITE Initializing built-in extension DAMAGE Initializing built-in extension MIT-SCREEN-SAVER Initializing built-in extension DOUBLE-BUFFER Initializing built-in extension RECORD Initializing built-in extension DPMS Initializing built-in extension Present Initializing built-in extension DRI3 Initializing built-in extension X-Resource Initializing built-in extension XVideo Initializing built-in extension XVideo-MotionCompensation Initializing built-in extension SELinux Initializing built-in extension GLX [dix] Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!

I tried downgrading Xpra to 0.15.10 with Ubuntu 14.04 and works like a charm. Also, try the whole same procedure in Ubuntu 16.04 and it works as expected (no errors nor warnings). In the client I only have one screen (disconnected the second one and rebooted even). I tried with other computers as clients and it’s just the same. The problem is in the xPra server. I attach as well an export of the server configuration done with xPra. _______________________________________________ shifter-users mailing list [email protected] http://lists.devloop.org.uk/mailman/listinfo/shifter-users
