Binary package hint: mc

Release: Jaunty Jackalope
Version of MC: Current as of apr 26, 2009
Expected:

MC able to save and restore the shell screen

Actual:

MC blanks out

Detail:

When on a virtual console,

Using control-O to flip between MC and the subshell causes the screen to be erased.

Diagnosis:

The problem is that for some reason a vc login isn't granting the appropriate permissions on /dev/vcs*
Which in turn means that mc is unable to read /dev/vcsa*

Kludgy workaround:

I wrote a suid-root C program to grant world rwx to /dev/vcs* every time I log in on VC.

Changing the files so that the user has read/write permission to /dev/vcsa* solves the problem. I suspect that mc is a victim of a bug elsewhere that fails to grant a console user the appropriate permissions /dev/vcs* upon a login.
