F11: LiveUSB Screen Resolution Issue

[Jaguar07]

Hi everyone:

I have been creating LiveUSB images and had great success is most cases lately with F11 x64.

One issue seems to be reproducible.

On some computers, when I boot with a LiveUSB x64 F11 I get the same screen resolution options I would have with a typical OS.
On some systems, I get results that are less desirable.

Example the Dell I am on at the moment only offers screen resolutions of 1024X768 or lower. The video card on this system is an Nvidia 8300GS and on another system using an Nvidia GTX260 I get the expected gammut of screen resolution choices using the same LiveUSB drive.

When I searched the LiveUSB drive for xorg.conf the file is not found.


So, Where does the liveUSB F11 x64 OS obtain it's video configuration information from? I would love to modify a file or setting so that I have the higher choices available.



Thanks,

Jag

The new xorg system can live without xorg.conf. It determines the appropriate settings with the help of HAL. This is more flexible than hard-coding video options. However, you may create your own xorg.conf and try to overwrite the automatic settings. But that will probably result in more hardware dependencies and a less portable live system.

Sometimes disabling kernel modesetting will give you more resolution choices. To try this add the keyword "nomodeset" to the kernel command line. On a live usb the file to edit is called syslinux.cfg in the syslinux directory.

Thank you for the suggestions. I tried both methods and had no success. I now believe it to be a driver bug or a limitation of the video card itself. Even when I hard code the video to the latest Nvidia driver the resolution options are maxed at 1024x768.
