Re: [cdesktopenv-devel] crashing on Manjaro Linux
Antonis, I always use dtlogin to start CDE and have no problems. caveat: I'm running and older version of CDE. Add this to the end your boot scripts, after rpcbind is started, networking and DNS are up, etc.: /usr/dt/bin/dtlogin -daemon Then login graphically to CDE. When you exit CDE, it should prompt you to save your session. The next time you login, it should restore any clients you had open when you last exited. If you use dtlogin, it starts Xsession for you. To the best of my knowledge, startx is for running X outside of a session manager. You login on a text console and just type 'startx'. While it can take arguments, I've never had to give it any. See startx(1) about the arguments. startx processes your ~/.xinitrc if you want to start some clients automatically, and finally should execute your preferred window manager. If you want to use dtwm with the startx method, just change /usr/X11R6/bin/mwm to /usr/dt/bin/dtwm in ~/.xinitrc, as below. If doing this, do *not* start dtlogin (as above). Example: cut here # $HOME/.xinitrc # Commands in this file are run when you run 'startx'. # startx runs xinit, which starts the X Windows System when you are # not using a display manager, e.g. xdm(1). # # start some xclients xclock & xterm & # # exec window manager last and not in background if [ -x /usr/X11R6/bin/mwm ]; then exec /usr/X11R6/bin/mwm else exec /usr/X11R6/bin/twm fi cut here Xsession, on the the hand, is used with a login manager like xdm(1). To use xdm, you would start it at the end of your boot scripts: exec /usr/X11R6/bin/xdm > /var/adm/xdm.log 2>&1 & Then you should be presented with a graphical login. xdm will process ~/.xsession and takes the place of .xinitrc used in the startx method. cut here # $HOME/.xsession # X session startup # When logging into X via xdm, /usr/X11R6/lib64/X11/xdm/Xsession # (global) is run, then this script is run. # This is an executable shell script. # All commands should be run in the background except the # window manager which is started last. # # start some xclients xclock & xterm & # # Exec window manager last and not in the background exec /usr/X11R6/bin/mwm > $HOME/xsession.log 2>&1 cut here dtlogin works like xdm, only you start it with /usr/dt/bin/dtlogin -daemon instead of /usr/X11/bin/xdm & Choose one method: startx --OR-- xdm or dtlogin. Do you have ~/.xinitrc and/or ~/.xsession files? Try renaming or removing them. Other places to check for errors: * Xorg log, usually /var/log/Xorg.$DISPLAY.log * Dtlogin.errorLogFile, usually /var/dt/Xerrors On the hung/frozen process thing, try strace(1): $ ps -ef | egrep 'X|Xsession|dtlogin|dtwm' ## depending on what is running $ strace -p pid_of_process When I'm logged into CDE using dtlogin, I have these processes running: $ ps -ef | egrep 'X|Xsession|dtlogin|dtwm' | grep -v egrep root 3775 1 0 Oct28 ?00:00:00 /usr/dt/bin/dtlogin -daemon root 3783 3775 0 Oct28 tty1001:23:21 /usr/bin/X :0 -auth /var/dt/authdir/authfiles/A:0-ZZAhRD root 3971 3775 0 Oct28 ?00:00:00 dtlogin <:0>-daemon user1 4055 3971 0 Oct28 ?00:00:00 /bin/ksh /usr/dt/bin/Xsession user1 4091 4075 0 Oct28 ?00:02:11 dtwm scot Antonis Tsolomitis wrote: Steps: while in mate-desktop rm -rf .dt/ rm -f .dtprofile logout and login to CDE.

cyrus torros wrote: Given that CDE has been given many a modern patch and is now used on beefy machines mostly, how is its resource use? I can't speak to the bleeding edge versions of CDE as I'm still running version 2.2.3, well before the switch to the autotools build system. Why haven't I upgraded? Because for me, it does what I need it to. That said: In 2015 I ran CDE 2.2.3 on an old ThinkPad Pentium III 1.0 GHz with 1 GB RAM (32-bit system) on Slackware Linux. I ran 4 virtual desktops, lots of dtterms, firefox, seamonkey, etc. all without any issues. That system was recently "retired" due to aging hardware. At one point I also ran CDE (probably same version) on the same ThinkPad running FreeBSD 9.x with no issues. I used whatever version that was in the FreeBSD ports/binary packages at that time. I'm currently running CDE 2.2.3 on a desktop Pentium 4 3.0 GHz with 4 GB RAM (64-bit system) on a highly modified/updated version of Slackware Linux. I built CDE from source. The system is from about 2005 and I have no issues. I am able to run multiple copies and versions of web browsers (firefox, seamonkey), watch youtube videos, and run audacity all at the same time. I would think CDE itself should run OK on your machine. The 512 MB RAM limit is definitely going to be a problem if you plan to run a modern web browser or an huge IDE like Eclipse though. How does the stock fvwm desktop perform on your machine? Are there other processes or daemons running that you don't need that you can shutdown? ___ cdesktopenv-devel mailing list cdesktopenv-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cdesktopenv-devel

Re: [cdesktopenv-devel] MS style alt tabbing
cyrus torros wrote:
Hello, I am wondering if anyone has devised any hacks to have MS style alt
tabbing in CDE?
Add this to your ~/.dt/dtwmrc.
Alt+Tab switches between applications on the current workspace/desktop.
Use Alt+F[1-4] to switch between workspaces.
You can choose different key strokes in the first column if you
prefer something else.
cut here
Keys DtKeyBindings
{
# Alt+Tab or Alt+up arrow = next window
AltTab root|icon|windowf.circle_up
AltUp root|icon|windowf.circle_up
# Alt+Shift+Tab or Alt+down arrow = previous window
Alt ShiftTab root|icon|windowf.circle_down
AltDownroot|icon|windowf.circle_down
# Alt+Fn key to move to specific workspace
AltF1 root|icon|windowf.goto_workspace One
AltF2 root|icon|windowf.goto_workspace Two
AltF3 root|icon|windowf.goto_workspace Three
AltF4 root|icon|windowf.goto_workspace Four
}
cut here
also, I am wondering if it is possible to use enhanced motif window manager
with it instead of mwm
It is an enhanced fork of MWM that has support for hints and other cool
stuff (can be found here https://fastestcode.org/emwm.html) (site does not
require javascript)
Good luck and let us know how it goes.

Maybe they shrink down some on a 32-bit machine, and depending on compiler options. My ksh is AT&T ksh93u compiled with libm so maybe that's why it is larger. Bash 4.2 on the same system uses 2988, so not much better. bash does not use libm. One thing I’d like to point out though, is that the Xserver itself is taking over 20MB, and it’s not fair to count that against CDE. That's true but you need X to run CDE so you really can't avoid it. ___ cdesktopenv-devel mailing list cdesktopenv-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cdesktopenv-devel
