[ddccontrol-users] nvidia_open: cannot open /dev/mem: Permission denied

[Massimo T. <mas...@ya...>]

GeForce 6200 agp and Samsung 193p with Debian Sid.

As a normal user gddccontrol doesn't find the monitor and outputs in the
terminal: "nvidia_open: cannot open /dev/mem: Permission denied".

With sudo everything is fine, but in this way I cannot use the
ddccontrol applet in the gnome panel..

Hi Massimo,

Sorry for the delay...

In the case you have not solved your problem yet, could you run this
command ?
# ls -l /usr/local/bin/ddcpci /dev/mem (or /usr/bin/ddcpci if you
installed ddccontrol to /usr)

You should have this output :

crw-r-----  1 root kmem  1, 1 Jul 27 18:17 /dev/mem
-rws--x--x  1 root root 80964 Nov 27 16:04 /usr/local/bin/ddcpci

Best regards,

Nicolas

You're right, this was my output:

crw-r----- 1 root kmem  1, 1 2005-12-27 23:55 /dev/mem
-rwxr-xr-x 1 root root 20568 2005-12-03 15:27 /usr/bin/ddcpci

I've done a 'chmod u+s /usr/bin/ddcpci' and now it works fine..

Thank you very much !

That's strange that it was not done automatically by "make install",
could you please try to run "make install" in ddccontrol/src/ddcpci, and
send me the output of this command and of "ls -l /usr/bin/ddcpci" ?

Thanks,

Best regards,

Nicolas

Probably the problem is related to dpkg. 
For compiling the sources I use dpkg-buildpackage that runs configure,
make and make install and creates a .deb Debian package. Then I install
the package with my package manager. I use this method to keep track of
all the files on my system.

The permission is set wrong during the creation of the deb file, but
it's the first time that I have such problems.
