Hi to all
Since new update from OpenELEC to 3.0.1, I got HDMI Handshake problem.
So I try now XBMCuntu and I would like edit file "amdpcsdb" to fix HDMI Handshake issue.
In folder "ati" I don't have permission.
If I type command "ls -lah" I got:

Code:

drwxr-xr-x 4 root root 4.0K Jan 29 16:35 .
drwxr-xr-x 6 root root 4.0K Jan 29 16:39 ..
drwxr-xr-x 2 root root 4.0K Apr 30 13:50 ati
drwxr-xr-x 3 root root 4.0K Jan 29 16:35 OpenCL

I create during installation a user like "ich" and password "123456", with this user I can log in truth WinSCP, but can't edit "amdpcsdb" file, I got error:

Code:

Permission denied, error code:3

I try "sudo passwd root", "sudo su" without success.
How I can edit this file?
Thank you in advance for any help.
