The packages there were made before I checked the dependencies (ie, they are what the debian control files say are needed, rather than what are definitely required.)

Unfortunately the Mac with my definitive list on has just gone back for repair.....

The i915 driver has been disabled in the kernel Kconfig as this driver is known to cause latency problems. If the distribution was properly built, you can use vesa or fbdev and have 1080p or 4K resolution. The i915 KMS DRM driver is not required for high resolutions. Unless you are playing video games on it, llvmpipe with fbdev will be fine.

Well, it might be that the driver causes latency problems, but not on all devices. And this particular hardware does not give any resolution higher than 1024x846 with vesa (fbdev and modeselect fail).

This is what lspci -v says:
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])

I have had problems like this a few times, especially running Virtual Machines on my Mac. (5880x2440 screen)
Google searches tend to suggest xrandr but alll I have had much success with is creating an Xorg.conf file and forcing a resolution the old school way.

Hello guys I attempted to follow Andy's advice to tommylight on installing the rtai files in www.linuxcnc.org/temp on mint 19.2.

If I run the latency test after a reboot the graphical window comes up but the displayed numbers stay at 0.

If I run the stepconfig wizard for a 4 axis setup using the defaults I get the following error report.
Warning: Spoiler! [ Click to expand ]


Any tips for why the configuration has an error?

Some update on my screen reolution issue: If you have the same problem - stuck to 1024x768 - it's sufficient to create this monitor definition and restart Xorg (adjust the "Virtual ..." to your needs):
# /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Monitor Model"
	HorizSync       28.0 - 60.0
    	VertRefresh     43.0 - 72.0
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Virtual 1280 1024
	EndSubSection
EndSection

Other thing I want to mention: "stepconf" needs "gir1.2-gtk-3.0", which is not in the dependencies of the linuxcnc *.deb-file. If it's not installed, you get a cryptic error message.

Will there be some a new version for testing?

I followed these instructions on a debian 10 system.
github.com/andypugh/RTAI/releases

uname -a shows this:
Linux X3CNC 4.14.132-rtai-amd64 #1 SMP PREEMPT Mon Jul 8 23:47:38 BST 2019 x86_64 GNU/Linux

Should this still be showing PREEMPT?

I did not successfully install 28. I got a bunch of dependency issues.
sudo dpkg --install linuxcnc_2.8.0.pre1.4891.gadf1eff73_amd64.deb

Unfortunately this doesn't work on my machine with i915 graphics. :(

You have to enable "source code" repositories in the "software sources" from the main menu>administration.
