Hi José, The problem lies in the primary buffer (extracted from your xorg.log):
[ 153.672] (II) NVIDIA(0): Setting mode "nvidia-auto-select" [ 153.735] (EE) NVIDIA(0): Failed to allocate primary buffer: out of memory. [ 153.735] (EE) NVIDIA(0): *** Aborting *** [ 153.735] Fatal server error: [ 153.735] AddScreen/ScreenInit failed for driver 0 You have this graphic card: GPU GeForce 7025 / nForce 630a (C61) Have you tried to install the nvidia drivers 173 instead of 256? Have you installed the latest grub-common and grub-pc packages (1.98+20100722-1ubuntu1)? José, this is just an idea (if the above does not help), but you might try to edit the file: /etc/grub.d/00_header by adding an extra line after the line: set gfxmode=${GRUB_GFXMODE} Add this line there: set gfxpayload=keep Like this: ... set gfxmode=${GRUB_GFXMODE} set gfxpayload=keep ... Save the file and then run in terminal: sudo update-grub and reboot (of course nvidia drivers installed and correct xorg.conf after running "sudo nvidia-xconfig"). -- nvidia drivers not working https://bugs.launchpad.net/bugs/607551 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
