Thanks for responding to my post,
here is the outpost of the commands:
sudo inxi -G
Graphics: Card: NVIDIA C61 [GeForce 7025 / nForce 630a]
X.org: 1.13.0 drivers: (unloaded: fbdev,vesa) FAILED: nouveau tty size: 122x39 Advanced Data:N/A for root
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
800x600 60.3 56.2
Memory allocated to the video card is 256 MB, Like I said before I can run a higher resolution (normally 1440x900) without any problems.
I just can get it automatically when start the computer, I have a 24" monitor, so 1024x768 is very small resolution.
I think your problem is that the Nouveau driver for your Nvdida card has failed to load, (highlighted in red). When I run same test
it shows that my driver is Catalyst (fglrx) for my ATI card.
Graphics: Card: Advanced Micro Devices [AMD] nee ATI Juniper [Radeon HD 5700 Series]
X.Org: 1.12.4 drivers: ati,fglrx (unloaded: fbdev,vesa,radeon) Resolution: email@example.com
GLX Renderer: ATI Radeon HD 5700 Series GLX Version: 4.2.11672 - CPC
Without the accelerated driver, your card will run at a default resolution.
Follow this guide first:http://community.linuxmint.com/tutorial/view/176
It contains a second link in Step 1 which you must follow.
This will blacklist the Nouveau driver and allow you to use Nvidias proprirtary driver.
Running nvidia-xconfig will generate an /etc/X11/xorg.conf file (not needed by KMS
but will be parsed and settings loaded).
Looking through sysnaptic current driver may be called nvidia-173 or similar.
Once loaded you should be able to use your 1440x900 resolution. This should
be set by either Xorg.conf, krandr aor nvidia-settings. Install nvidia-settings
You can test if acceleration is enabled by running
