X server fails after upgrade Dapper > Edgy

I also decided to reconfigure the xorg.conf it by running

dpkg-reconfigure xserver-xorg

Because the new xorg.conf has some entried about a wacom input devide, I decided to comment those lines hoping that could resolve the issue, but it didn't. Attached is my actual xorg.conf.

Please attach /var/log/Xorg.0.log

X still doesn't work.

Here it is my Xorg.0.log

I have been playing around and I have found that the nv driver causes the xserver to fail. I successfully tried using vesa and vga drivers to launch X.

I had exactly the same issue:

This for me was easy to resolve I simply had to run

sudo apt-get install nvidia-glx

whilst logged into the new kernel:

However I cannot boot from any of the previous kernels as they bomb out on Xserver-Xorg errors.

I tried to add/enable 3D... in edgy. Got that working ok, but then X started locking up. Even back to stock ati driver (which was used no matter 3D or not).... Anyway, some of error files. I have to login terminal or ssh into same ... Nothing good works for video while logged into Gnome.

Good luck.

I am experiencing the same problem. My laptop's video chipset is an S3 Savage, which works fine with Dapper. In reconfiguring xserver-xorg, it makes no difference whether I select the 'vesa' or the 'savage' driver; either way the console totally hangs. I cannot even switch virtual consoles nor send CTRL+ALT+DEL to make the box reboot.

I can, however SSH in from another box and use a shell, but that's all that is possible.

I originally upgraded from Dapper but today installed Edgy fresh (from Netboot). I suspect the problem is related to a recent patch to Xorg or the kernel, as things previously did work fine with Edgy on this notebook until kernel 2.6.17-8 was released.

Have just noticed that setting acpi=off in the kernel boot options seems to make X work. It did not, however, work on the system I'd upgraded from Dapper to Edgy. This could be because of some pre-Edgy cruft or it may be that an update to a package in the 3-4 days since I last tried has made X at least work with ACPI disabled.

I had noticed that on booting I got a dozen or so messages on the system console which look possibly ACPI-related, like the below example :

Calling INT 0x15 (F000:F05E)
  EAX is 0x5F03

Same problem (or result) today after upgrade via apt-get on a Compaq 900 laptop.

Rebooting after the upgrade fails at the Xserver. Trying startx from the command line gives the following errors:

X: warning; process set ti priority -1 instead of requesting priority 0. giving up.
xinit: Connection refused (errno 111): unable to connect to X server
xinit: No such process (errno 3): Server error.

using sudo startx, I just get

xinit: server error

Same problem
its a simple fix
Xorg isnt installed :-P
so sudo apt-get install xorg
and you're all set
at least here

I had the same results as RJ Marsan, xorg was not installed. When installed everything just worked.
strange.

xorg is a dependency of ubuntu-desktop; this metapackage must be installed in order to ensure that all of the proper packages are installed for desktop functionality. Update Manager copes with this automatically and this is one reason why it is the officially recommended upgrade path.
