X2go "qt_geo_map calling GLX 1.3 function "glXCreatePbuffer" when GLX 1.3 is not supported!"
This seems to be a X2go server issue, as described here
Therefore, there are 4 reasons why certain modern “3d-ish” desktops are incompatible with nxagent, and therefore X2Go. The desktop environment requires a newer version of the X11 extension “GLX” (OpenGL) than nxagent 3.5.0.x and X.org 6.9 provide (version 1.2).
I did some tests on
- Ubuntu 16.04 Mint
- CentOS 6.8
I tried both Qt for linux installations for Qt 5.8 and Qt 5.5.1
In CentOS 6.8 Qt 5.8 even fails to install
With Qt 5.5.1 in CentOS 6.8 and Qt 5.8 in Ubuntu 16.04 Mint I get this error trying to run the QtWebView minimal sample
failed to get the current screen resources WARNING: Application /data/home002/pvicente/git/star_icvs/tools/build-qt_geo_map-Desktop_Qt_5_5_1_GCC_64bit-Debug/qt_geo_map calling GLX 1.3 function "glXCreatePbuffer" when GLX 1.3 is not supported! This is an application bug! QSGContext::initialize: stencil buffer support missing, expect rendering errors QXcbConnection: XCB error: 172 (Unknown), sequence: 163, resource id: 150, major code: 149 (Unknown), minor code: 20
*This seems to be a pure X2Go error *, since trying ON THE LOCAL TERMINAL (in Ubuntu 16.04 Mint with Qt 5.8, the program runs fine.
thanks for any help
This is the error trying to install Qt 5.8 or Qt.5.4 in CentOS 6.8
