This is known: KDE Plasma 5 needs OpenGL 2. Try use Software accelerator instead of hardware: echo 'QT_XCB_FORCE_SOFTWARE_OPENGL=1' > ~/.bashrc echo 'LIBGL_ALWAYS_SOFTWARE="true"' > ~/.bashrc This will add two line in /home/[username]/.bashrc : QT_XCB_FORCE_SOFTWARE_OPENGL=1 LIBGL_ALWAYS_SOFTWARE="true" Or you can create /etc/xdg/plasma-workspace/env/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 |
