Switching between VUE & CDE

[Arthur Corliss]

Is it possible to have both CDE and VUE installed on the same system, and allowing each user to select their preferred environment?

Yes & No ... you can have CDE & VUE installed on the same system, however they will contend for the Xserver process & for control of the DISPLAY, probably giving an error along the lines of : cannot connect to DISPLAY:0 or something about permissions on sockets.

CDE by default starts at run-level 3 so will grab the Xserver first, VUE will fail, starting normally at run-level 4. You can swicth between the 2, but you'd have all users login via one or the other not some CDE and some VUE :(

VUE to CDE
1) From the VUE login (vuelogin) select Options -> No Windows.
As soon as the screen goes blank, press return. You should see
a Conole Login prompt. Login as root.
2) /usr/dt/bin/dtconfig -e (enable CDE)
3) /etc/init 2 (change run-level)
4) Log back in as root.
5) /etc/init 3 (start CDE)

CDE to VUE
1) From the CDE login (dtlogin) select Options -> Command Line Login.
As soon as the screen goes blank, press return. You should see
a Conole Login prompt. Login as root.
2) /usr/dt/bin/dtconfig -d (disables CDE)
3) /etc/init 2 (change run-level)
4) Log back in as root.
5) /etc/init 4 (start VUE)

Great info, there. Thanks for the run-down. :-)
