Sounds like when you turn off wicd, then ifup and ifdown work the way
you want them to.
Yes. But this is not the way I wanted it, since this PC is supposed to
be used by a number of persons who may not be at ease in opening an
Xterm, switching to superuser with the appropriate password and then
typing 'ifdown eth0' 'ifup...' every time they wish to connect or
disconnect. With the old Lenny system - before I upgraded - they easily
connected and disconnected doing a right click on the NetworkManager
icon on the gnome desk.
So, since I had so little success with the NM and Wicd programs that I
had on my system, I first removed the 'Wicd' and 'Wicd-daemon' packages
and then tried to see if a newer version of NetworkManager was available :
#apt-get install -s network-manager
showed that it was a matter of replacing a huge number of packages by
newer ones, including gnome packages etc... After a short hesitation, I
decided to go ahead.
#apt-get install network-manager
did a thourough job !!! At one time, it warned that : "The nm applet
could not find some needed resources ; it cannot continue...". I clicked
on the OK, and the process nevertheless continued up to the end.
Then I re-booted.
The newly installed network manager (yes, it did install despite the
warnings that the applet could not continue) seems to work better then
the old one. It does operate connecting and disconnecting upon clicking
in the right place.
But my system now behaves in a weird way !
At first, it is.... very very slow ! 5 to 10 full seconds to wait an
xterm to open after clicking to the icon that is supposed to open it ;
same thing with any program.
The program 'top' shows that 90% of my CPU is used by "mutter", which is
supposedly a kind of desk manager... 10% of the CPU is taken by Xorg,
only a fraction of one percent is free to other applications !!!
I very briefly read the man page of mutter, and tried to shut it down:
#mutter --replace
Then the system got a lot more speed... except that a lot of functions
were now unavailable: I can't drag and drop xterms, I can't go from one
desk to another....
Thanks in advance for your help in restoring a convenient desktop
environment
