I've run sudo make setuid and successful installed LinuxCNC. but when I run ../scripts/rip-environment linuxcnc, there is an error :

LINUXCNC - 2.9.0~pre0
application-specific initialization failed: no display name and no $DISPLAY environment variable
Error in startup script: invalid command name "image"
    while executing
"image create photo -file $f/$i.gif"
    invoked from within
"if [file exists $f/$i.gif] {
            return [image create photo -file $f/$i.gif]
        }"
    (procedure "linuxcnc::image_search" line 7)
    invoked from within
"linuxcnc::image_search linuxcnc-wizard"
    invoked from within
"set logo [linuxcnc::image_search linuxcnc-wizard]"
    (file "/home/tsinglin/linuxcnc-dev/tcl/bin/pickconfig.tcl" line 31)

I'm using Wayland as my display server. What should I do now?

Thanks

If you were in the ~/linuxcnc-dev/src directory then the commands should be:

. ../scripts/rip-environment 
linuxcnc

note the space between the first two dots

As an alternative, you could run:

~/linuxcnc-dev/scripts/linuxcnc

This command can be run from any directory.

Hi

I followed your advice but still have the same error:

~/linuxcnc-dev/scripts/linuxcnc
LINUXCNC - 2.9.0~pre0
application-specific initialization failed: no display name and no $DISPLAY environment variable
Error in startup script: invalid command name "image"
    while executing
"image create photo -file $f/$i.gif"
    invoked from within
"if [file exists $f/$i.gif] {
            return [image create photo -file $f/$i.gif]
        }"
    (procedure "linuxcnc::image_search" line 7)
    invoked from within
"linuxcnc::image_search linuxcnc-wizard"
    invoked from within
"set logo [linuxcnc::image_search linuxcnc-wizard]"
    (file "/home/tsinglin/linuxcnc-dev/tcl/bin/pickconfig.tcl" line 31)

Is there other problems?
I am using Wayland as display server. There may have some difference.

Thanks

Look if XWayland is running.

Are you running via ssh to the LinuxCNC machine, or actually at the LinuxCNC machine?

ie, is the monitor and keyboard that you are using plugged in to the LinuxCNC machine?

I see exactly the same issues when I try to run LinuxCNC via ssh on my Mac with Buster (but it used to work fine pre-Buster, as long as I used ssh -Y)

If this is a problem with a display local to the LinuxCNC machine then I am as puzzled as anyone else.

Hi andypugh

I'm running LinuxCNC on my board with a keyboard and monitor. But whatever I run on the board or execute the cmd on my terminal. It appears the same error.

Hi, rmu

I already make Xwayland run now. But when I run LinuxCNC,it shows me the same error.

LINUXCNC - 2.9.0~pre0
application-specific initialization failed: no display name and no $DISPLAY environment variable
Error in startup script: invalid command name "image"
    while executing
"image create photo -file $f/$i.gif"
    invoked from within
"if [file exists $f/$i.gif] {
            return [image create photo -file $f/$i.gif]
        }"
    (procedure "linuxcnc::image_search" line 7)
    invoked from within
"linuxcnc::image_search linuxcnc-wizard"
    invoked from within
"set logo [linuxcnc::image_search linuxcnc-wizard]"
    (file "/home/tsinglin/linuxcnc-dev/tcl/bin/pickconfig.tcl" line 31)

I'm sure the Xwayland is running. I can see it by "ps -aux" cmd.

Thanks

maybe your startup scripts don't export the appropriate DISPLAY environment variable. You could try launching LinuxCNC with

DISPLAY=:0 ~/linuxcnc-dev/scripts/linuxcnc

Look in /etc/ssh/sshd_config if X11Forwarding and related options are set to sensible values. In the ssh session, DISPLAY should be set to something like localhost:10.0 by the ssh daemon.
