That's because xscanimage cannot open your scanner device; /dev/sg?<br>
|
|
probably has permission `rw-------' allowing root access only.<br>
|
|
<p>
|
|
Either make it accessable to everybody (`chmod 0666 /dev/sg?') -<br>
|
|
potential security risks involved; or make it accessable to a special<br>
|
|
"scanner user" group and make xscanimage SETGID, or configure `sudo'<br>
|
|
to allow the users to use xscanimage (preferred solution).<br>
