Gnome Lock Files

In some cases Gnome will no longer let a user login because there are some lockfiles that weren't removed the last time the user logged out. These files are:

• ~/.gconfd/lock
• ~/.gconf/%gconf-xml-backend.lock/

Just remove these files and the login error should go away. If not, most likely the account is over quota, which can be checked with the command 'quota -v' If the account is over quota, files will also need to be removed before the user can log back in. The "Failsafe Xterm" session option that can be chosen from "Sessions" at the login screen can be used to get access to an xterm while the account is broken.

Otherwise, contact the Systems Operator for assitance removing the lockfiles.

XCursor

X Resources go into ~/.Xresources for Linux machines.

To revert to default cursors, set Xcursor.core to true.

Xcursor is configurable via environment variables and X resources.

(resource/environment variable): type...

• Xcursor.core/XCURSOR_CORE:bool

  Whether to use core cursors exclusively, overriding any available Render extension capability.

• Xcursor.size/XCURSOR_SIZE:int

  Nominal size for cursors. Themed cursors can have multiple sizes for each cursor, Xcursor picks the size closest to this size from those available. If Xcursor adds SVG support, this size will be used to scale the SVG objects.

• Xft.dpi:int

  If Xcursor.size isn't set, then this value is used to compute the nominal size = dpi * 16 / 72

• Xcursor.theme/XCURSOR_THEME:string

  Name of theme. Xcursor uses the freedesktop.org icon theme specification to locate cursor files; cursors live in one of the icon directories in a cursors subdirectory. Xcursor looks in the standard icon directories, along with /usr/X11R6/lib/X11/icons. It also parses the index.theme file to follow Inherits values. If no theme is set, Xcursor uses 'default'

• Xcursor.dither/XCURSOR_DITHER:threshold/median/ordered/diffuse

  Dithering algorithm when creating core cursors. Xcursor transforms an ARGB cursor into a two color cursor with one of these algorithms (yes, only ordered and diffuse are really dithers). The default is ordered, which is a 2x2 ordered dither.

• Xcursor.theme_core/XCURSOR_THEME_CORE

  If the server doesn't support ARGB cursors, this value controls whether Xcursor goes ahead and themes core cursors using the core cursor requests.

RealPlayer

To setup RealPlayer for Linux:

1. Install the soft/RealPlayer10 module.
2. Create the ~/.mozilla/plugins/ directory
3. Run these commands
   ln -s /soft/RealPlayer10/Linux/mozilla/nphelix.xpt ~/.mozilla/plugins/
   ln -s /soft/RealPlayer10/Linux/mozilla/nphelix.so ~/.mozilla/plugins/
