[git] Cannot run denise with an error 'GLXBadFBConfig'.

[Frederic Bezies]

Hello.

I tried to launch a freshly git build. But I cannot get i run, both in Wayland and Xorg.

Here is the error log:

(denise:17804): Gdk-WARNING **: 18:09:09.205: The program 'denise' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadFBConfig'.
(Details: serial 4034 error_code 167 request_code 152 (GLX) minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

ok I will check it for Arch Linux

I can’t reproduce it when testing in Manjaro, running on VMWare.

When does the error occur?
immediately when Denise is opened or when emulation is started. In the latter case, please switch the setting 'Threaded Renderer' under Options/Video and then start the emulation.

If you haven’t already please checkout latest git master and try a “make clean” before “make --jobs=3“ (builds faster on 3 CPU cores)

Still no luck on my Manjaro Gnome (unstable) and mesa 21.3.3-2.

Denise won’t start

[PiCiJi]

has it ever run in older versions of Denise ?

I have readed about some problems with mesa 21. I am using mesa 20, couldn’t update to mesa 22.

I tried successfully Denise 1.1.1. Weird.

[PiCiJi]

hmm strange, I will compare both versions for relevant changes

‌

[PiCiJi]

please try latest master branch if it works. maybe it needs some “try and error” to fix this.

besides of that vsync runs smoothly again.

[Frederic Bezies]

It works correctly, now. So this issue can be closed.
