pls, I am a new user of linux.
I just installed Kubuntu (10.04), did some upgrades and updates then upon booting the computer wont go beyond the login page. at first it posted a message (Xsession:warning: unabele to write to /tmp; X session may exit with an error).
I followed some instructions from the net which asked that I do the following:
ctr+alt+f
aptitude clean of apt-get clean
cd /var/log
rm *.gz
rm *.0
rm *.1
rm (all big files)
rm kern.log
rm syslog
reboot

after this, when I login it no more goes off, but the desktop wont still come on, instead a terminal (konsole) window is open but when I try start x it refuses.

(the only method I use to start my computer succesfully is though the recovery mode)

could some one help me out??????
