openSUSE screen blanking!!!

Posted 09-11-2013 at 12:47 PM by nobahn (Learning Linux on OpenSUSE 12.3 (and seeking help!))

So, OK: I'm sitting at my computer reading my textbook. When I look up, I'll occasionally see a rectangle being briefly shown with a percentage; if I move the mouse, then the rectangle will reappear and the percentage will go to 100%.

Today's feature:
  • A C/C++ utility (script if you have runc-rs) to change symlinks to url files.

[Requires runc-rs or at least librunc.a from runc-rs.
Doesn't require mint to work, nor even a deb derivative.]

This experiment today is significantly less ambitious than the deb repository builder thingy in the previous blog entry and is again a nice intro to C/C++...
