hi everyone,

I met a problem. Before I shut down the computer, I run some C++ program with saving data files in the computer. But next time when I start the computer, it said the space is not enough to start the kde. Then I login to the save mode and deleted some files. And restart, this time I cannot only login kde, but also, I cannot delete any files. I only can read them.

When I typed kde, the following error occurred:
xsetroot: unable to open display
xset: unable to open display
xset: unable to open display
xset: unable to open display
ksplash: cannot connect to X server
kdeinit: Aborting. $DISPLAY is not set
Warning: connect() failed: : Connection refused
The following installation problem was detected
while trying to start KDE:

No write access to $HOME directory (/home/elfyl)

KDE is unable to start
ksmserver: cannot connect to X server
Warning: connect() failed: :Connection refused
Error: Can't contact kdeinit!

I cannot copy out any file. What happened to the linux?

Thank you very much

Try logging in as root and do the following

1) reconfigure X, use your favourite script or text-editor
2) chown elfyl:users /home/elfyl -R

hi, karma,

Thank you very much for your kind reply. The problem is I cannot open any text-editor. and I am not good at linux, I do not exactly know how to configure X. Would you like to help me again?

Thanks a lot.

First off, you should be logged in as root at a terminal. We're good to go if you see a hash mark ('#') or whatever you want to call them at the end of the last line on your screen.

Commands for editors:
These are some editors that can be run from the command line. Usage is <command> <path to target file>.

Really easy editors (you might not have them installed):
nano
pico

almost-easy:
vi
vim (if vi doesn't work, and it should)
joe

Your X windows configuration is stored in a file, typically /etc/X11/xorg.conf or /etc/X11/XF86Config. You can open this file in one of the aforementioned text-editors like so:

# pico /etc/X11/xorg.conf

and follow the comments (lines preceeded with '#') in the file.

There are several X-configuration scripts and utilities available from distribution to distribution to help you configure X without having to use the config file directly. From the command line, try the following commands:

# XF86configurator
# xf86configurator
# setup

Your particular flavour may well include a graphical X configuration utility that will run X in a hardware-friendly mode while you configure its settings with the comfort of a mouse.

Now, as for the thingie, just type that in exactly as shown at the command line. And I mean _exactly_, or terrible spooky goings-on will happen in your machine
