Classic Ladder not working with LinuxCNC Rio

Will do that once back from Thanksgiving holidays.

I have some logs created. In the logs you find the different rio.hal and rio.ini configurations.
Twopass disabled
loadusr -w classicladder --modmaster vfd.clp in postgui_call_list.hal

Lcnc, Rio, Modbus all looking good. GTK not so much though (Failed to load module "atk-bridge").

Are you on a VM or accessing your linux session via VNC or XRDP by any chance? Additionally, it would be a proactive move to list/describe all the GTK debugging steps undertaken so far so that others seeing this can be updated on your progress. Bet it's an easy fix.     

Re: Failed to load module "atk-bridge"
Not sure how relevant that error message is but according to this
dev1galaxy.org/viewtopic.php?id=1815
you could maybe try:

It's working now! I am not 100% what really the solution was. I did 3 things:

1. Deactivated Twopass
2. Installed the missing libatk-adaptor package.
3. Added some CL nets to the hal file.

Now the GUI starts and CL starts in Modbus mode.
