There is an issue with mesa indeed, I can reproduce it on the Zenbook

Running strace gives me:

Code:

open(“/usr/lib/i386-linux-gnu/libtxc_dxtn.so”, O_RDONLY|O_CLOEXEC) = 13
read(13, “177ELF11133122010004”…, 512) = 512

mmap2(0xf03d9000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 13, 0x34000) = 0xfffffffff03d9000
close(13) = 0
mprotect(0xf03d9000, 4096, PROT_READ) = 0
futex(0xf7062b2c, FUTEX_WAKE_PRIVATE, 2147483647) = 0

Found a workaround in the ARCH!1! Forums: https://bbs.archlinux.org/viewtopic.php?id=155009

On Ubuntu run:

Code:

sudo apt-get remove libtxc-dxtn-s2tc0:i386

The game should now launch

And by doing that you won’t be able to play any other game that needs S3TC under linux.

Yes, that’s why it’s only a workaround and not a proper solution. The bug seems to happen only with recent versions of this lib so I might consider adding it to the lutris runtime (based on Ubuntu 14.04)

Update: I added libtxc-dxtn-s2tc0 to the runtime, reinstalled it on my laptop and the game still fails to launch. At this point, I don’t see any reliable solution, I wish there was some kind of LD_UNLOAD to prevent a lib from loading.

The gdb backtrace clearly points to something going wrong in mesa:

Why is it calling stdc++6? The game needs stdc++5.

The executable seems to be linked against libstdc++6:

Code:

ldd nwmain | grep libstd
libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf4e06000)

Removing it makes the game complain about the lack of it.

[linuxgnuru]

besides; by using

Code:

sudo apt-get remove libtxc-dxtn-s2tc0:i386

I get

Code:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
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: 32
Current serial number in output stream: 33

i honestly didn’t realize i even had mesa installed;

[strider]

If you’re not running the proprietary NVidia driver or AMD Catalyst then you’re running mesa, it’s the open source OpenGL implementation.

Try renaming nwn.ini to something else and run the game again to see if you get different results.

Also, can you paste the output of xrandr?

[linuxgnuru]

that’s the thing; i’m using Nvidia’s 355.11 driver

xrandr:

Code:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
LVDS-0 connected primary 1920×1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm
1920×1080 60.02*+
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)

[strider]

wait, you’re on the nvidia driver? something’s very wrong then…

your monitor has only one resolution available, which is weird but instead of renaming nwn.ini try changing the resolution to 1920×1080

Code:

[Display Options]
…
Height=1080
Width=1920

[linuxgnuru]

not weird when it’s a laptop. I’m at work now; will try that when i get home

[strider]

Is your laptop Nvidia only or does it also have an integrated GPU? That could explain why it tried using mesa. There’s an option to run games with primusrun in Lutris btw.

[linuxgnuru]

nvidia only
