OpenGL error messages at startup cause error messages

smoe commented 2 years ago

Here are the steps I follow to reproduce the issue:

install Debian bullseye
run linuxcnc
press "OK" (cancel is fine)

This is what I expected to happen:

no idea, it is the first time I started this

This is what happened instead:

$ linuxcnc LINUXCNC - 2.9.0~pre0 Machine configuration directory is '/home/moeller/linuxcnc/configs/sim.axis-1' Machine configuration file is 'axis_mm.ini' Starting LinuxCNC...

Information about my hardware and software:

I am using this Linux distribution and version (often, shown by lsb_release -a):

No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux bookworm/sid Release: unstable Codename: sid

I am using this kernel version (shown by uname -a):

Linux x230 5.15.0-3-amd64 #1 SMP Debian 5.15.15-2 (2022-01-30) x86_64 GNU/Linux

I am running ...
- [ ] A binary version from linuxcnc.org (including buildbot.linuxcnc.org)
- [X] A binary I built myself
- [ ] A binary version from some other source besides linuxcnc.org
I am using this LinuxCNC version (shown in package manager or, for git versions, scripts/get-version-from-git):

A recent master, the bug has been reported also for the RPi.

I am using this user interface (GUI) (e.g., AXIS, Touchy, gmoccapy, etc):

Just the linuxcnc application started from the home directory - KDE.

I am using this interface hardware vendor and chipset (e.g., parallel port, ethernet port, FPGA card):

Nothing attached. Just a blank laptop, not even running a realtime module.

There's a bunch of broken stuff, and I agree with you, they should ideally be fixed, but failing that they should not be in the package. PRs gladly accepted.

I am very happy to hear that we no longer have that dependency on GLUT. I just grepped for it and nothing popped up. Happy.

To make sure we are all on the same page, and have me recreate a new .iso for it, would you mind to upload a new version of the Debian package? That soft freeze the day after tomorrow would be another reason :o/

From #debian-devel:

uploaded. See -- Happy hacking Petter Reinholdtsen

I tried again on a fresh Bookworm without GLUT and I can confirm that Gmoccapy runs under X11 (RIP). But still problems on Wayland:

Xlib.error.DisplayConnectionError: Can't connect to display ":0": b'Authorization required, but no authorization protocol specified\n'

After sudo xhost +

I get

 File "/home/cnc/linuxcnc/linuxcnc-2.9/lib/python/gremlin.py", line 244, in reshape
    self.xwindow_id = GdkX11.X11Window.get_xid(widget.get_window())
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: argument self: Expected GdkX11.X11Window, but got __gi__.GdkWaylandWindow

I only wonder why gremlin is working under Axis. I thought it's the same code used there.

SebKuzminsky commented 1 year ago

@hansu, does @JetForMe's suggestion of GDK_BACKEND=x11 help? https://github.com/LinuxCNC/linuxcnc/issues/2264#issuecomment-1411221972

If so I suggest we add it here: https://github.com/LinuxCNC/linuxcnc/blob/2.9/scripts/linuxcnc.in#L25-L29

hansu commented 1 year ago

Yes export GDK_BACKEND=x11 does the trick, great! Sorry, I lost a bit track on all these OpenGL stuff. Yes let's add it there!

jepler commented 1 year ago

Since gtk cannot create a compatibility context we need the x11 backend for now too create it via glx calls. Major updates are needed to gremlin before it works with "modern" opengl. I support adding the environment variable workaround unconditionally though I'm not fully aware of the downsides (I don't use Wayland anywhere yet)
