But this is easy: The difference between Linux and Windows app_info.xml is only the file names and app versions.
So adapt this file names in the xml, copy it in the project folder and restart the client.

All newer cards need an app_info.xml to work with MW.

Like this (Linux):
You have to edit the file names and versions.

3) Message boards : Number crunching : Insufficient amount WU on the server (Message 64003)

Do 15 Okt 2015 13:37:15 CEST | Milkyway@Home | Scheduler request completed: got 0 new tasks

Especially with fast GPU's it is impossible to get enough work yet.

Tentatively i have activated modified-fit yesterday.
To date, over one day no error occurred.
It seems ok.

All results under linux with NVidia 331.67 and AMD 14.4-2:

Run time (sec) | CPU time (sec) | Credit
AMD HD 7870 boost (tahiti Chip) | 152.99 | 8.21 | 213.76 (Two WU's simultaneously; so divide Run time by 2.)
83.65 | 40.15 | 106.88 (Two WU's simultaneously; so divide Run time by 2.)

AMD R7 Spectre (A10-7850K) | 1,105.01 | 9.96 | 213.76
553.32 | 5.02 | 106.88

AMD R3 Kalindi (Athlon 5350) | 4,816.01 | 2,056.16 | 213.76
2,411.88 | 1,018.88 | 106.88

NVIDIA GeForce GT 635M | 1,222.49 | 77.63 | 106.88 (Modified Fit don't work, because the libc6 is too old. But you can, as you can see in the other, appreciate the double time: 2,444 s)
6) Message boards : Number crunching : PC with AMD GPUs and the LinuxMint 14 64bit Cinnamon system (Message 61753)

Post:
The AMD GPUs run very well on Linux for Milkyway, the tahiti based in particular.

For the driver installation you have two options:
1. Installation of the distribution packages (debian based works good).
2. Or of the driver packages from the AMD side [1].

In any case, you have, as opposed to windows, also install the AMDAPP SDK [2]. Although it indeed explicitly for CPU, but without boinc does not recognize the GPU.

Furthermore, one must consider when AMD OpenCL, the need for a user to be logged in Xserver must and will be allowed on this access to the GPU.
Actually you just have to, every time you log in,
xhost + local
run and then boinc start/restart.
Also you can use
clinfo
to check whether the OpenCL GPU is detected below a user or root.

7) Message boards : Application Code Discussion : wrong videocard detection (Message 61750)

Post:
Ok, the same problem with new igp like Kalindi (Kabini/Athlon APU) and Spectre (Kaveri APU).

So I'll try it with the app_info.xml.

Post:
Yes, the problem ist still available on all my linux clients.
All other projects and mw@home, nbody are ok.
Even on an old debian lenny (very old libc) system!

I just deactivate modified_fit in config (as long as it dosn't work) .
