Linux/Mandriva beginner here.
For some reason, my monitor (Samsung SyncMaster 960bf,) whenever it's set in 1280 x 1024 resolution, the screen appears to be offcentered, with about a 1/4 of an inch of a vertical black bar on the left hand side of the screen, with everything else shifted over.
Now, I read that I should check the XF86Config file in /etc/X11 folder and make sure the refresh rates for both the vertical and the horizontal settings are to be inline with the manufactured specifications. The ones listed are wrong, so I changed them to what they should be, however when I clicked save as and wanted to overwrite it, a menu popped up saying that it couldn't overwrite it and that I should check if I have access or enough space (which I do have enough space.)
So my question is, why isn't it letting me overwrite the file?
