[one-users] noVNC problems AND question about VM images [OpenNebula 3.2.0 on openSUSE]

[Hector Sanjuan]

Hello,

about your noVNC problem, please comment the TIGHT_PNG line in
/usr/lib/one/sunstone/public/vendor/noVNC/include/rfb.js:

        encodings      = [
            ['COPYRECT',         0x01 ],
-        ['TIGHT_PNG',        -260 ],
+        //['TIGHT_PNG',        -260 ],
            ['HEXTILE',          0x05 ],
            ['RRE',              0x02 ],
            ['RAW',              0x00 ],
