trouble with video monitor, 4.4.0

once again, having troubles getting video monitor working ( ardour 4.4, av linux 6.0.4).
the Video Monitor checkbox in the Window menu cannot be checked, no xjadeo window appears even though the video seems to be correctly imported and i can see it on the timeline.

some time ago i was encountering similar problems

https://community.ardour.org/node/7355

but none of the solutions mentioned back then works for me now. if i remove the xjremote file from the ardour dir, the Video Monitor entry is grayed out and ardour log argues about xjadeo version being too old.

installing the requested xjadeo v. 0.8.0 from the av linux deb (http://bandshed.net/avlinux6-debs/xjadeo/xjadeo_0.8.0-static-avlinux6-1_i386.deb) helps neither. in fact, this version doesn’t work for me even from the command line, the output is:
tomas@avl6:/$ xjadeo
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 138 (ATIFGLEXTENSION)
Minor opcode of failed request: 66 ()
Serial number of failed request: 13
Current serial number in output stream: 13

i was trying to install other (newer) versions of xjadeo, but wasn’t successful in solving the dependencies.

any suggestions? thanks!

Looks like your system does not support openGL. Do other openGL applications run? try glxgears (a simple opengl test/demo app, available on most systems) also the output of glxinfo may shed some light.

PS. Binaries from http://xjadeo.sourceforge.net/ which are also shipped with Ardour are self-contained (no dependencies, except for X11/openGL)

thanks for fast reaction!

binaries from http://xjadeo.sourceforge.net/ give the same result
tomas@avl6:~$ xjadeo
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 138 (ATIFGLEXTENSION)
Minor opcode of failed request: 66 ()
Serial number of failed request: 13
Current serial number in output stream: 13

so does glxgears - exactly the same terminal output

glxinfo has one more line:
tomas@avl6:~$ glxinfo
name of display: :0.0
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 138 (ATIFGLEXTENSION)
Minor opcode of failed request: 66 ()
Serial number of failed request: 13
Current serial number in output stream: 13

with every linux install i always struggle to get my dual head setup and graphics in general working properly, it is possible that something strange / non-standard could have happend in the process. it is strange though that the old xjadeo 0.6.4 works fine, at its own or with older versions of ardour.

what should i do to fix this?

reinstalled the fglrx video drivers, xjadeo 0.8 sort of works now. in ardour, i can see the xjadeo window, but no picture, just frozen time. if i start xjadeo externally and sync it with ardour via jack or mtc, it works fine.
