# rent  desktop,  otherwise  it contains a '-' character. The next
# two columns contain the fixed string DG: and  then  the  desktop
# geometry as '<width>x<height>' (e.g. '1280x1024'). The following
# two columns contain the fixed string VP: and then  the  viewport
# position  in  the  format '<y>,<y>' (e.g. '0,0'). The next three
# columns after this contains the fixed string WA:  and  then  two
# columns  with  the workarea geometry as 'X,Y and WxH' (e.g. '0,0
# 1280x998'). The rest of the line contains the name of the  desktop
