Xpra: Ticket #1043: glTexParameteri error

I am trying this on Ubuntu 14.04 with Xdummy.


On server:

xpra start :10 --xvfb="Xorg -noreset -nolisten tcp +extension GLX \
    -config /etc/xpra/xorg.conf \
    +extension RANDR +extension RENDER -logfile ${HOME}/.xpra/Xorg-10.log" \
    --sync-xvfb=50 \
     --bind-tcp=127.0.0.1:10000 \
     --start=libreoffice


On client:

xpra attach tcp:localhost:10000:10 --desktop-scaling=0.5


However, there is no display till I deactivated opengl from the menutray.
Client console repeats with the following error intermittently till opengl is disabled:

No display when opengl is enabled even with xdummy driver (no xvfb)

Display works when opengl is disabled.

This seems to be a recurrence of this bug (#565), I guess.


Thu, 26 Nov 2015 20:52:17 GMT - zenny:

I have uninstalled python-opengl and installed the latest PyOpenGL in pursuant to ticket:1024#comment:6, yet the error remained the same.
There is a reference to this bug in ticket:1036#comment:16 and ticket:1036#comment:17, too.

$ sudo dpkg --remove --force-depends python-opengl
$ sudo easy_install PyOpenGL


Howevever the issue remained unchanged with error:

Like Antoine pointed out (ticket:1036#comment:16), this is pertinent to a specific distro like Ubuntu 14.04. I tried xpra client in Debian Jessie 8.2 and the glTexParameteri error is no more. However the xpra server is still in 14.04. Yet there are errors in the client console as of quoted below:
UPDATE: BOTTLENECK
ffmpeg capture stopped working with this xpra+Xdummy setup with 4k modeline in customized xorg.conf :

Fri, 27 Nov 2015 17:53:43 GMT - Antoine Martin: status, summary changed; resolution set

the glTexParameteri error is no more. However the xpra server is still in 14.04..


The opengl error is a client side rendering issue, which is probably due to buggy drivers in Ubuntu Trusty.


Yet there are errors in the client console as of quoted below: .. ZeroDivisionError: float division by zero


Thanks, this should be fixed in r11319.

Closing this ticket as a duplicate of #1024. Please include your chipset information in that ticket so that we know what to blacklist.

The ffmpeg errors are not related to this ticket and very unlikely to be caused by xpra.

In the same setup, if I use xpra with xvfb, the rendering is fine and the ffmpeg fails to capture only when with Xdummy, fyi.
I assumed that it could be the ffmpeg bug discussed here: https://trac.ffmpeg.org/ticket/4575, even using the latest patched ffmpeg source and compiling didn't help, fyi.
The capture works till I attach the virtual x server to an xpra client, and once attached the ffmpeg capture dies. So this has something to do with xpra, I guess.


For my case, the capture is very important. If you have any hints or inputs to look anywhere in the system further, please put forth. Appreciate it!

Thanks. Patch applied.

You are not including the command lines you used, my guess is that you forgot to tell the server to skip resizing with XPRA_RANDR=0.

But, as I understand, disabling RandR is only for Xvbf xpra instances as it does not support neither RandR nor OpenGL. Lately, I am using Xdummy with xpra instead. Or?

No. If randr is not supported it will not be used (ie: Xvfb).

This switch makes xpra skip randr even if it would normally be supported and used.

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
>                   Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server
avahi_client_new failed.
The program 'Xpra' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 12450 error_code 3 request_code 3 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
