Use software rendering in case when OpenGL supported by graphics card is older than 2.0
This is known KDE Plasma 5 needs OpenGL 2.
Try use software rendering in case when OpenGL supported by graphics card is older than 2.0
Create /etc/xdg/plasma-workspace/env/plasma-Qt5-OpenGL2.sh or /etc/X11/xinit/xinitrc.d/10-plasma-Qt5-OpenGL2.sh file with content (and make this file executable):
#!/bin/sh OPENGL_VERSION=`LANG=C glxinfo | grep '^OpenGL version string: ' | head -n 1 | sed -e 's/^OpenGL version string: \([0-9]\).*$/\1/g'` if [ "$OPENGL_VERSION" -lt 2 ]; then QT_XCB_FORCE_SOFTWARE_OPENGL=1 export QT_XCB_FORCE_SOFTWARE_OPENGL fi
gnastyle: and probably we should make opengl2 the default
