[SOLVED] Pete's XGL2 Linux PSX GPU / Nvidia 32bit OpenGL Broken?

quequotion · 2015-04-14 19:15:23

I'm trying to do some tests with pcsxr and ePSXe using this plugin.

It's 32bit, closed-source, and quite dated, but still one of the most functional plugins for PSX emulators.

PCSXR (cross-compiled in 32bit), just keeps crashing:

Failed to create OpenGL context!!!
Segmentation fault (core dumped)

In fact it segfaults even with its built-in OpenGL and XVideo plugins as well.

Less than a year ago I was using 32bit pcsxr with this plugin on the same machine... not sure what's changed.

After installing a number of obscure dependencies, I got ePSXe running but it crashes when this plugin is selected:

./epsxe 
 * Running ePSXe emulator version 1.9.26. 
 * Memory handlers init. 
 * ePSXe: PSX BIOS loaded [/home/david/ROMS/PSX/bios/ps-41a.bin]. 
 * Init internal cdrom ... CD_Init: open of "/dev/sr0" failed (123)
 * Init gpu[0][libgpuPeteXGL2.so] 
The program 'epsxe' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 18 error_code 2 request_code 154 minor_code 3)
  (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 --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I get the same sort of problem running the windows version of ePSXe in wine:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  1523
  Current serial number in output stream:  1524

I have both 64 and 32 bit versions of both nvidia and mesa's libGL, and I suspect that the plugin is trying to load the wrong library.

Is anyone else using Pete's XGL2 plugin with a PS1 emulator in archlinux?

EDIT: This may be affecting all 32bit OpenGL programs. I can't get any games to run in wine at the moment; they all crash with the same error.

No problem here with Intel GPU:

 * Init gpu[0][libgpuPeteXGL2.so.2.0.9]
Intel Open Source Technology Center
Mesa DRI Intel(R) Haswell Desktop x86/MMX/SSE2
 * Open gpu[0]

Older version of ePSXe here, 1.9.4, but I somehow doubt that makes a difference. BTW, which obscure dependencies? The config utilities for some of these old plugins are GTK1, which might be considered obscure nowadays, but that's it.

Edit: Do you have lib32-nvidia-libgl installed?

There are reports of similar errors for various things and the nvidia driver... 64bit OpenGL programs with the same driver version seem to be fine; but it could be something broken in the 32bit nvidia drivers.

Actually, I don't know of a way I can check which libGL the programs are trying to use; is that possible?

Yes, gtk1 (which was still installed from the last time I tried this, when it worked) also lib-compat for libstdc++-libc6.2-2.so.3, and a few others for ePSXe 1.9.25.

Do you have lib32-nvidia-libgl installed?

yaourt -Qs libgl
multilib/lib32-mesa 10.5.2-1
    an open-source implementation of the OpenGL specification (32-bit)
local/lib32-nvidia-libgl-beta 349.16-1
    NVIDIA library symlinks (32-bit, beta)
extra/libglade 2.6.4-5
    Allows you to load glade interface files in a program at runtime
extra/libglademm 2.6.7-3
    A C++ wrapper for libglade.
extra/mesa 10.4.3-1
    an open-source implementation of the OpenGL specification
local/nvidia-libgl-full-beta-all 349.16-1
    NVIDIA library symlinks (beta)

Of course beta versions are not supported, I know, but I doubt that the problem is the drivers themselves (only seems to affect 32bit programs).

I've reinstalled the drivers and I'm going to try a reboot; maybe everything will be broken

glxinfo32 from the lib32-mesa-demos package

Ok, back to normality.

Maybe I had forgotten to reboot after a previous reinstall of the drivers?

Still not sure what was wrong with 32bit pcsxr, but ePSXe is working now.
