Hi. I have a dual graphics card setup on my laptop, an intel and an nvidia. To use the nvidia for specific programs I have to run the command like so:
optirun glxgearsthis will run glxgears through the nvidia card.

So I can't seem to get POL to do this. If I edit the shortcut scripts and change:
POL_Wine "Steam.exe" to
optirun POL_Wine "steam.exe"nothing happens and the error log says command POL_Wine not found.

Is there a setting I can change somewhere or is there a way to alter the script to make this work?

You could edit POL_Wine function in wine.lib ?

Thanks for the quick response!

Is wine.lib a file? I checked Tools/Manage Wine versions but that doesn't let me edit any settings.

You're a genius. Found it in /usr/share/playonlinux/lib/. That was exactly what I was looking for.

For anyone who finds this, I editing /usr/share/playonlinx/lib/wine.lib. Searched for "POL_Wine ()" and changed
wine "$@" ...
to
optirun wine "$@" ...

It's a nasty hack but it runs optirun.

Hello everyone.

I tried editing the /usr/share/playonlinux/lib/wine.lib and it didn't work for me. I don't see any "optirun application_name" anywhere in the terminal. Is there something that I may be missing?

Please read all the messages.

Well. I did read all the messages and I did change the function from wine.lib but it seems that nothing happenes... is as if PlayOnLinux won't use the POL_Wine () function. What kind of output do you think I should post here in order to make myself clear?..

POL uses POL_Wine for every shortcut

OK, so I started POL in the terminal:

and started Steam in debug mode:

Writting log to /home/razvan/.PlayOnLinux//tmp/errors_Steam.log.e

[POL_Wine_SetVersionEnv] Message: Setting wine version path: 1.3.33, x86
[POL_Wine_SetVersionEnv] Message: "/home/razvan/.PlayOnLinux//wine/linux-x86/1.3.33" exists

[...]

so... if I do "lsmod | grep -i nvidia" I get nothing... and I don't see any optirun anywhere, and I have this in "wine.lib":

[...]
if [ "$LOGFILE" = "/dev/null" ] || [ "$KeepOutput" = "True" ]
then
optirun wine "$@"
else
optirun wine "$@" >> "$LOGFILE" 2>> "$LOGFILE"
fi
errors="$?"
[...]

so what am I doing wrong here?... if you have any idea...

You missed the important part of the log

Thanks for your time... but this isn't helping very much if I'm not pointed in the right direction... I am new to POL so I have no idea about what 90% of this stuff is... what is the important part of the log? so that I can rectify my post...

I think your problem has nothing to do with optirun. Post a new topic and explain exactly what you are trying to do, run and paste the full output
