I install ubuntu feisty Beta i386 on my labtop acer extensa 5620 and it boots fine until i run updates then when i restart it displays a message startx failed? The driver is set to vesa.

Try to reconfigure your X graphic server:

1) try to access to a pseudo tty (a terminal) press CTRL+ALT+F3:
Make a login with your user and password and go to point 3.

2) If you can use Gnome Gui:
Please open a Terminal from the menu Applications->Accessories->Terminal:

3) To reconfigure xorg please type:

cd /etc/X11
cp xorg.conf xorg.conf.vesa
sudo dpkg-reconfigure xserver-xorg
answer to the simply question, then reboot the system, type:
sudo reboot

give your user password when requested, you don't see nothing when you type it, then press enter.

Thank you

OK i tried that and it said that x- server for this graphics card was not found. So here is my specs for my video driver

Mobile Intel GM965 Express Chipset with integrated 3D graphics,featuring Intel Graphics Media Accelerator (GMA) X3100 with up to 358/3845 MB of Intel Dynamic Video Memory Technology 4.0 (8 MB of dedicated system memory, up to 350/3765 MB of shared system memory), supporting Microsoft DirectX 9

I did not see that on the list for x server driver

Thanks Pedro Fragoso, that solved my question.
