Hey guys.
i recently attempted to change my root file system from ext3 to XFS.
it all went wrong, so booting knoppix, i had to mount my nre root XFS pattion,
mount an empty Ext3 partiton, and copy all the files from XFS to ext3. thus re-setting all my file permissions.

at first, nothing worked, couldnt start X, couldnt access home directory.

anyways, ive fixed the home directory by
chmod 700 -R /home/myuser
chown -R myuser /home/myuser

and i set /tmp and /var to be read /write by all users.

i then restarded my font server

and after that, i can now startX. however KDE is acting strangly.
for eample, when i create a new link to application on the desktop, the link fails with the error kdeinit could not start "program name"

also, when in the main menu i try to load konsole, it loads the window and all the tool bars, but no prompt is shown, and it will not take input.

i found some files relating to kde in /opt/ so i set othat to read/write too.

that am i missing ???

thanks

everything works ine when i log in as root.
i think the problem lies with suid,

ive set suid bit on the binary startx, but this doesnt work. i dont want to just suid all my binary's, in X11R6 but ii dont know which ones i should do !

well... partly to show off, and partly incase any one else ever finds tis thread and has had the same problem.....

i fixed with
chmod +s /usr/libexec/pt_chown
chmod 666 /dev/pty*
chmod 666 /dev/tty*

well, when i say fixed, i mean my konsole is back.

all my openGL programs still segfault if i run without root permissions.

and by using
i found errors reported about unable to open file '/dev/zero'
so chmod 666 /dev/zero and glxgears nolonger segfaults.

if you ever want to learn somthing about linux... do somthing stupid like reset all file permissions.
you learn loads, and look loke a but of a guru linux porn star in forums

I suspect that you haven't changed the permissions of your hidden directories.
In your home directory try:will be needed to get everything.

If I may make a suggestion, free up a partition of only a few gig and install another installation. Use that as a guide as to what the permission should be. Then you can remove that small installation. For example, If you have /var on a seperate partition, you could mount relocate /var in a subdirectory of the root dir; remove the old /var partition and install in that space.

all is fixed. now.
the rpoblem is i performed a network install, which took 7 hours, and i needed my system back and up again fast. anso, i didnt have the needed free space.
