[LinuxCNC/linuxcnc Issue#256] linuxcnc does not start with mesa board About GRBL HAL

Issue #256 | 状态: 已关闭 | 作者: valeriob01 | 创建时间: 2017-04-10

Here are the steps I follow to reproduce the issue:

1. run pncconf and generate a config
2. run linuxcnc
3. freeze up

This is what I expected to happen:

axis gui shows up

This is what happened instead:

axis gui does not start

I am not sure that this is a LinuxCNC bug as such. This seems likely to be a problem specific to your particular PC.
What happens if you edit the INI file to use tklinuxcnc rather than axis in the [DISPLAY] section?

I did the change and nothing shows, it is frozen again:

What do I have to do after physically installing the mesa board? install some driver ?

#3 – andypugh 于 2017-04-10

The Mesa drivers are built-in to LinuxCNC, no extra config should be needed.
Can we move this to the forum?

#4 – valeriob01 于 2017-04-10

Yes, already done, but now I have a trace:

@valeriob01 reports in email that they fixed the configuration problem and things work now:
