Re: IO permission problem
Ok, I fixed the permissions, currently I have:
-rwsr-xr-x 1 root root 872936 AUG 11 12:57 /usr/local/bin/qw-client-svga
In this way I'm able to start the program.
But a problem still exists. This way my mouse don't detected. I got the message
on the screen after quiting:
'No mouse found'.
Starting the program as root: it is ok.
Thanks
Attila
