Bc_desktop error

Dear All,

I am trying to install bc_desktop on our “ppc64le” cluster. Since there is no turboVNC availble, I installed tigerVNC instead. The result is this config doesn’t work and the following is the output.log. Would you please give me some advice for that?

Thank you in advance,

It is also possible your cache file is out-of-date; it may help to try:
$ module --ignore-cache load “ondemand-vnc”

Also make sure that all modulefiles written in TCL start with the string

VNC parameters:

Parameters can be turned on with - or off with -=0
Parameters which take a value can be specified as -
Other valid forms are = -= –=
Parameter names are case-insensitive. The parameters are:

Global Parameters:
ZlibLevel - Zlib compression level (default=-1)
ImprovedHextile - Use improved compression algorithm for Hextile encoding
which achieves better compression ratios by the cost of
using more CPU time (default=1)
pam_service - Alias for PAMService
PAMService - Service name for PAM password validation (default=vnc)
PlainUsers - Users permitted to access via Plain security type (including
TLSPlain, X509Plain etc.) (default=)
GnuTLSPriority - GnuTLS priority string that controls the TLS session’s
handshake algorithms (default=NORMAL)
MaxCutText - Maximum permitted length of an incoming clipboard update
RemapKeys - Comma-separated list of incoming keysyms to remap. Mappings
are expressed as two hex values, prefixed by 0x, and
separated by → (default=)
BlacklistTimeout - The initial timeout applied when a host is first
black-listed. The host cannot re-attempt a connection until
the timeout expires. (default=10)
BlacklistThreshold - The number of unauthenticated connection attempts
allowed from any individual host before that host is
black-listed (default=5)
QueryConnectTimeout - Number of seconds to show the Accept Connection dialog
before rejecting the connection (default=10)
QueryConnect - Prompt the local user to accept or reject incoming
connections. (default=0)
AcceptSetDesktopSize - Accept set desktop size events from clients.

AcceptCutText - Accept clipboard updates from clients. (default=1)
AcceptPointerEvents - Accept pointer press and release events from clients.
AcceptKeyEvents - Accept key press and release events from clients.
DisconnectClients - Disconnect existing clients if an incoming connection is
non-shared. If combined with NeverShared then new
connections will be refused while there is a client active
NeverShared - Never treat incoming connections as shared, regardless of
the client-specified setting (default=0)
AlwaysShared - Always treat incoming connections as shared, regardless of
the client-specified setting (default=0)
Protocol3.3 - Always use protocol version 3.3 for backwards compatibility
with badly-behaved clients (default=0)
FrameRate - The maximum number of updates per second sent to each client
CompareFB - Perform pixel comparison on framebuffer to reduce
unnecessary updates (0: never, 1: always, 2: auto)
ClientWaitTimeMillis - The number of milliseconds to wait for a client which
is no longer responding (default=20000)
MaxIdleTime - Terminate after s seconds of user inactivity (default=0)
MaxConnectionTime - Terminate when a client has been connected for s seconds
MaxDisconnectionTime - Terminate when no client has been connected for s
seconds (default=0)
IdleTimeout - The number of seconds after which an idle VNC connection

Hey @superdavidxp

What version of TigerVNC do you have deployed?

OOD launches VNC sessions with help from our ood_core package, -log is being passed to vncserver here:

We ran into a similar error. OOD does not like tigervnc-server for some reason. We found the best bet was to just install TurboVNC.

We did this by using easybuild (since it wasn’t available via yum) and adding “module load TurboVNC” to the batch connect vnc wrapper script.
