Description Tom Hughes 2009-07-08 04:41:59 EDT
Description of problem:

vncviewer ignores the -LowColourLevel switch and uses a 24 bit full colour connection.

Version-Release number of selected component (if applicable):

tigervnc-0.0.91-0.11.fc11.x86_64

How reproducible:

Every time.

Steps to Reproduce:
1. Run "vncviewer -LowColourLevel 2 <host>".
2. Note that the output says "Using pixel format depth 24 (32bpp) little-endian rgb888".
3. Note that the view takes ages to redraw if the host is on a slow link.
  
Actual results:

A full colour connection is used.

Expected results:

The requested connection type is used.

Additional info:

It seems that the old realvnc client in previous releases had the same problem - the only difference was that it defaulted to an 8bpp connection instead of a 32bpp connection.
Comment 1 Adam Tkac 2009-10-07 11:06:28 EDT
After discussion in upstream this is actually not a bug but a feature. When you would like to use reduced color level you have to specify also -AutoSelect=0 parameter.

Main reason is that some users would like to use auto select mode and would like to control which reduced color level is used when autoselecting code decides to switch to reduced color level.

Currently there is another bug in code - you have to use -FullColor=0 in addition to -AutoSelect=0 parameter to get -LowColorLevel working as you wish. This will be fixed in the next release.
