Re: [X2Go-User] qt5 application window not rendered

[Bernd Schubert]

Hmm, very weird. So after upgrading to current mesa didn't help either,
I wanted to try newer QT, as there are no QT ppa packages available. I
just updated QT5 from the next ubuntu version (18.04). Now these libs
seem to incompatible with any installed qt5 package - it purged all
related packages. I don't know if the update would have helped - there
was nothing left to test with... So I went back to the previous QT
version and also just let it install qgit. Somehow this made it work
again in x2go. Not the ideal way to solve it, but at least it works...

No, nx has an own (old) copy of mesa.

Just plain mesa packages from ubuntu. So I now switched to a slightly
more recent version using a ppa - same issue. Besides, wouldn't it be
required to rebuild x2go, so that x2go uses those mesa libs internally?

Have you upgraded mesa or your gfx driver recently? Can you try
reinstalling them?

[X2Go-User] qt5 application window not rendered

[Bernd Schubert]

Hi all,

somehow qt5 application windows are not rendered anymore. I think this
came with the upgrade to ubuntu 17.10, but I'm not totally sure. My
desktop is xfce and I only rarely run qt applications - I recently
noticed that qgit is broken and then noticed that not a single qt5
programm works. Applications linked to qt4 seem to work fine.

So when I run qt5 programs, it brings up window, but this just shows
whatever was under that new window, but not the real not content.
Outside of x2go it works fine, of course.

I also just updated x2go to the unstable nightly (Version:
2:3.5.99.12-0~201801110901~ubuntu17.10.1), same result.

Before updating to the nightly build, it complained about xkb errors
when I started qt5 programs, right now nothing except a gtk2 warning
comes up.

Is there any way to trace what is going on? I'm rather clueless about X
debugging.



Thanks,
Bernd
