Assertion failed under Kubuntu when Blending Unit Accuracy <> None
#1
So in troubleshooting my network problems I installed Kubuntu. Then I decided to tinker with PCSX2, to see how it's progressed on the "other side."

Specs are as in my sig. Using proprietary Nvidia driver (nvidia-current) on Kubuntu 15.04. PCSX2 was installed from gregory's PPA. OGL HW. Tried multiple games(FFX-I, P3:FES, Ar tonelico, BIOS)

Using default settings, I discovered if I set Blending Unit Accuracy to anything but "None" then PCSX2 will throw an "Assertion Failed" on booting anything

Not sure why this is happening. Not sure if it's something I've got configured wrong or what. But I was curious, so I thought to post it.

What happens if you press ignore?

Pressing Ignore results in PCSX2 immediately crashing.

Sync MTGS = no change

Sync MTGS was completely stupid. That's why I deleted it shameful.

That warning comes from a gpu driver/gsdx problem. Please run from terminal and post what it says during the crash. Should help reveal more clues as to the problem. Of course if that doesn't help, Gregory will likely have you run a gdb on pcsx2 to dig deeper.

It's showing a lot of unsupported extensions... hmmm. Definitely using proprietary drivers:

Code:
(from lspci -k)

But I think they are too old. Let me update them.

I didn't realize "nvidia-current" package should actually be named "nvidia-old-as-*****" lol

sudo apt-get install nvidia-346 will help (or whatever version Ubuntu is using these days).

Just checked the Ubuntu packages site. Yup, it's nvidia-346.

Yeah nvidia-346 is what I did to fix it, thanks. Still, having a package named current that is actually horribly old is kinda deceptive and dumb IMO Ninja

Hum, a GL function is likely mandatory but I forget to add a check on it. Dunno which one Tongue2 It will be so much easier if GL implementations were more uniforms.

I'm close to make various GL4 extensions mandatory. I only keep them optional for OSx and DX10-Class proprietary driver (aka GPU support the feature but they didn't implement it on the driver...)
