I have a Dell Inspiron E1505 with the Ultra HighRez display. It has an Intel 945GM graphics card and can display 1680x1050@60Hz under Windoze XP. When I install Ubuntu, the config for Xorg gives me three choices, with 1024x768 being the highest resolution offered. Even then, though, the Gnome Display Manager quits and asks me to make fixes before restarting. I know that Intel has written a driver for the 945GM chipset that works with SuSE 9.3.

Has anyone had experience/success making the Gnome Display Manager work properly with this graphics card (at any resolution)? Which distro?

Has anyone had experience/success installing the Intel Linux driver for this card and making it work with Ubuntu 5.10? Any help will be greatly appreciated.

Thanks.

Have you tried just killing the X server and manually setting the stuff with "sudo xorgconfig" from the terminal?

You seem to have all the information you need for setting it up. The only thing that you would have to worry about are the sync ranges,but you know what it can handle at highest res - so it should work.

I made some progress with my Dell Inspiron E1505, but still have some stumbling blocks. I was unable to get the X server to start with Ubuntu Breezy 5.10 with the 1650x1080 WSXGA+ display and the Intel 945GM chipset. When I changed the device from "i810" to "vesa" and added a line for 12M of VideoRam, the X server comes up and the display works. However, the resolution is 1280x1024, so the aspect ratio is incorrect for the screen. The result is that graphics and text are stretched horizontally. (An image of me makes it appear that I gained 15 kg :-})

I looked at the 915resolution hack, but didn't try it, since it has to be applied with every reboot of the system. I also looked at the beta release of Ubuntu (Dapper 6.04 flight 6), but it also appears to have problems with this display and chipset.

Any other suggestions will be appreciated. Also, has anyone been able to make this display and chipset work properly with any other Linux distro? Thanks.

Have you tried 915resolution?
My notebook is a Asus W5F which also uses Intel 945GM, and its display is 1280x768.
The resolutions suppored by video BIOS of my notebook are 640x480, 1024x768, 1280x1024, 1600x1200,
and 1920x1440, so this tool is needed for me.
Maybe you should also tried it for your 1680x1050 display.
