No GUI after upgrading from Lenny to Sid
 

I have been running Lenny and it has worked OK
Recently I tried to upgrade to Sid and did following:
1. chanced lenny to sid in source.list
2. sudo aptitude update
3. sudo aptitude full-upgrade

After rebooting there is now GUI ... I just get a login prompt :(
There must be something basic I have missed ...

This means X fails to start. What vga are you on and with which driver?

Whet happens when you type
after logging in at the prompt

@zkab, I suggest that you look at the xorg logs to see what's wrong.

If you're not very familiar with Linux in general, and Debian in particular I strongly recommend that you stay with testing. If you decide to stay with SID, also look at apt-listbugs, mailing lists, etc.

oh I recall. I had this problem too. Is it gdm?
You have certinaly a problem with the
to be be checked. or the session. I dont recall.

that s a clearbug
then
I could pass through the issue with root typing.
give me info.
I forgot how I did it

I had this proble m from Etch to Lenny, so it means that they realyl have to work on this bug, man, really. Mine was stable, so ?? stable is stable?

to Slackware users, Is slack really more stable than Debian ?

Thank you guys for your help ...

I got it working after login, startx and installing some GNOME desktop software ... the system boots OK into a GUI environment
During boot process it suggests that I install GRUB2 with command 'upgrade-from-grub-legacy' which I did and after reboot I get:

GRUB Loading stage 1.5
GRUB loading, please wait ...
Error 15

and then it is DEAD ...

zkab, use a Linux CD to boot your distro and try:

(I don't remember exactly the commands so look at the boot options).

There should be a command to setup grub such as grub-install or installgrub, use it and setup grub on the mbr partition.

Reboot and see that nothing is DEAD.

Problem solved ... I executed 'grub-install' from the installation/rescue CD, rebooted and that did it
