Dear ALL,

I have installed Ubuntu Server 12.04 LTS 64 bit on
1. Mother Board -- INTEL S1200BTS
2. CPU -- XEON E3 1220V3
3. HDD -- 1TB Seagate SATA
4. RAM -- Transcend 16GB DDR3
5. ONboard graphic card SiliconMotion (SM712)LynxEM+

I have installed GUI(GNOME Desktop) through following commands
sudo apt-get update
sudo apt-get install ubuntu-desktop

At present the screen resolution is set to 800x600. I am not able to set the screen resolution to 1024x768 or higher.
I tried to download display drivers from INTEL website but drivers available only for Redhat & SUSE Linux.

I have tried following commands
(Below is the command and the output)

Please Help let me know how to set the screen resolution. ThankYou

Thanks & Regards,

Looks like you know how to set the screen resolution, unfortunately the driver support isn't there to support the 1024 resolution. Without that you won't be able to get the higher res. Maybe someone knows of a third party driver but without out you're kind of out options.

Hi Kustom42,
Thanks for the reply.I guess you are right driver support is not there

Manjunath, I also faced the same problem with ubuntu, so how did you fix the problem with ONboard graphic card SiliconMotion (SM712)LynxEM+. I belive I need to get a new supported Graphic Card. Can you advise any card both graphic and audio that will be supported under ubuntu.
