[SOLVED] Higan: system logs out when setting input

Hello.

I installed Higan and tried to set input from settings->configuration, input tab. I select a console and double click on one item, then I press a key (on the keyboard or joypad).
Now I double click on another item and the system logs out: I find myself on the login screen.

Why? What do I do?

Re: [SOLVED] Higan: system logs out when setting input

Can't confirm, does something crash? Do you get a coredump (

man coredumpctl

for more info) is there anything interesting in journal/dmesg and or your Xorg log? What's your hardware?

For xorg logs I did:

cat /var/log/Xorg.0.log

But I guess those logs are after the crash and the restart.

Re: [SOLVED] Higan: system logs out when setting input

Disclaimer: Your system will not be happy with higan, it is way too slow to actually  emulate at fullspeed should this even be workable in any shape or form. Use snes9x(-gtk) instead.

This said it still shouldn't kill your XServer like that. Does acceleration work normally? Can you post

glxinfo | grep OpenGL

. Still, chances are very likely that it tries to allocate some sort of buffer that is way too big for your hardware to handle, can you post an actual backtrace

coredumpctl gdb 24496
bt

Especially if you havent started a game yet it still might be a bug because it shouldn't attempt to do much fancy stuff already....

As for the Xorg log, in modern xorg and with the open drivers it should be at ~/.local/share/xorg/ if your xorg is started in rootless mode. Maybe ~/.xsession-errors contains some more info as well

$ glxinfo | grep OpenGL

Anyway, now magically I can set the input, but I encountered a number of other issues: missing files that prevent a rom from starting; blank screen and distorted sound, I guess it's like you said, I cannot run higan in this machine.
Not much luck even with zsnes, it crashes when I set fullscreen.

Use snes9x, zsnes hasn't seen updates in a long time, and is overall less compatible than  either higan or snes9x.

Yes, thank you, at least snes9x works. And sorry for this useless topic.

Re: [SOLVED] Higan: system logs out when setting input

Well its a strange problem, likely not something in higan itself, but some crash in the underlying layer. The only thing I could think of is that cairo tripped up because higan requested a OpenGL 3 core profile which doesn't work on your card and then ran into some cornercase that killed your xserver. But this shouldn't happen until you start a game so from that aspect it is still weird.

But yeah your machine is definitely too slow for higan, for reference I couldn't get a stable 60 fps on my 4.6 GHz  skylake. This turned out to be a problem in the intel_pstate powersave governor which didn't recognize the workload of higan to need a constant 4.6 GHz and it constantly switched frequencies and these switching differences made it stutter and jump between 55-60 fps. There switching the governor to performance helped, but your system in general is too old to be able to run it in fullspeed.

You can prepend [SOLVED] to the title of your topic if it is solved in your point of view.
