ok, thank you.
not, there no .xsession* files in home directory. i also see at /var/adm in logfiles for something interesent in that regard, and not found.
looks like any communication with xorg loaded driver problem, if boinc not run from session opened by kde ( window manager)?
try also do xhost +local:
also from root account in physical console. also try to run ./boinc in physical console from root account - always the same result - boinc stuck at gpu detection and not see gpu. when i run boinc from terminal session from kde - all be beautiful - detection is fast, and all found.
boinc is programm, who compute tasks on computer, also using for that a videocard ( GPU), if found any. looks like, ati videocards require x org running and x org videodriver loaded, then boinc can communicate with that driver and use it. Nvidia videocards \ drivers looks like better in that way - there is requiring to install kernel drivers, then you can log in in console (CLI) and boinc can use and detect Nvidia card without any X-es and another struggles...
sadly, but i need to get work ati videocard ( radeon 4350, catalyst 13.1 driver, amd SDK 2.9 for OpenCL, slackware64 14.0 )...and to work from console, not from terminal on WindowManager ( where it works ok)...:(

Others probably have more useful help, but I wonder if when starting boinc (after starting the dummy-wm), maybe use 'xterm -e sh /path/to/rc.boinc'?

Your kde log has ...which the other log file doesn't.

I don't know if that's relevant or not. I'm afraid that I won't be of much help. Sorry.

If you start xterm anyways to start boinc, you don't need the dummy WM, just use xterm as WM. In fact, any program can act as a WM in this way, possibly just starting BOINC instead of the dummy WM will work (as suggested already by business_kid).

xm, today at morning before get to job i try that ->

#!/bin/sh
xterm -e sh /Install/BOINC/boinc


into file dummy_wm_boinc
make it executable and do
xinit /Install/BOINC/dummy_wm_boinc

looks like X start, and then quit.
in logfile is a strange for me lines like "ctrl-alt-del pressed" or so on. put that log in evening, when got to home....
i be more and more not like ATI.
Nvidia looks like far better in driver quality and linux support than ati.
i have nvidia 210 videocard at work, and boinc work with it very fine - even without any Xes - computer started at runlevel 3, i log in as user, run ./boinc - and all detected, and running. with that ati i struggling more than week for now, and do not see a light at the end of the tunnel....

log file for try running


#!/bin/sh
xterm -e sh /Install/BOINC/boinc


into file dummy_wm_boinc
make it executable and do
xinit /Install/BOINC/dummy_wm_boinc
in attach:

There is no indication for an error in that log. It may be possible that BOINC has detached itself from the terminal, which would have closed the terminal automatically and therefore shutdown the X server. What happens when you start BOINC directly as WM, without using Xterm?

Woow!
i change dummy wm script to:
dummy_wm_boinc file, file perm 100755:

#!/bin/sh
##xterm -e sh /Install/BOINC/boinc --dir /Install/BOINC/
## > dumlog.txt
/Install/BOINC/boinc --dir /Install/BOINC >boinc.log 2>berror.log

then
xinit /Install/BOINC/dummy_wm_boinc

and there is boinc.log:

i e at least, looks boinc be started, and see a GPU. it is very great result. ill be try to test all this in this week.
also think about make a startup script for this, for can be start it from console, and that task remain running after console was closed...

thank you very much, and all another folks, who post there and help me.
:)
