changed: - $ insert stuff here. - $ qtcreator Qt: XKEYBOARD extension not present on the X server. Xlib: extension "RANDR" missing on display ":10.0". Could not initialize GLX Aborted <... hey, at least it crashes instead of hangs.> Note LIBGL_DEBUG=verbose and LIBGL_ALWAYS_INDIRECT=1 had no effect. A search of the internet suggested tightvnc has no GLX support. It's unclear if the alternative vnc4server does, with some bugs/posts suggesting it once did but now doesn't. The latest thing everyone recommends is TurboVNC with VirtualGL for client-side hardware rendering, but its comercial with no Debian debs. I tried vnc4server and it didn't help. 3. Why the hell does qtcreator need GLX anyway? A search tells me "qtcreator -noload Welcome" fixes it. And Hey! it's running! But WTF, and I'm not making this up, the keyboard mapping is all weird! Instead of a 'qwerty' keyboard I now have a 'c.gvn' keyboard... and only in qtcreator, all the other apps run fine. I guess that "XKEYBOARD extension not present" warning was serious. 4. try "--noload Welcome" with cygwin ssh'ed to the linux box: It works! Hooray! If anyone has any hints why so many of these attempts didn't work, I'd love to hear them.
I just want to run Qt5's qtcreator to do UI work on OpenTrack?. The problem is my current development platforms are;
It turns out qtcreate is a graphical IDE, and thus needs more than an ssh terminal to run. So things I tried are;
Install cygwin on the windows 7 box. I can run X11, ssh to the linux box, and run qcreator there! It doesn't work:
$ qtcreator libGL error: failed to load driver: swrast <...it just hangs with nothing happening, and needs ^C to exit> $ export LIBGL_DEBUG=verbose $ qtcreator libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so libGL: driver does not expose __driDriverGetExtensions_swrast(): /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: undefined symbol: __driDriverGetExtensions_swrast libGL: Can't open configuration file /home/abo/.drirc: No such file or directory. libGL: Can't open configuration file /home/abo/.drirc: No such file or directory. libGL error: failed to load driver: swrast function is no-op <... nothing again, needs another ^C> $ export LIBGL_ALWAYS_INDIRECT=1 $ qtcreator function is no-op <... and still nothing...^C>
It's just not working at all. Thinking maybe cygwins GLX stuff is dodgey, I ran glxgears. It creates the window with the gears, but then proceeds to claim 50~2000 fps with no visible changes in the gears window at all. That's with and without LIBGL_ALWAYS_INDIRECT=1. So maybe the GLX stuff is a bit dodgey.
Install xrdp, tightvnc, and LXDE on the linux box. Run windows remote desktop to access it and get a whole linux desktop running on the linux box in a window on the windows box. It doesn't work there either::
