Latitude X1 12.1" WXGA (Intel 915GM graphics) display problem


I already have a thread for this started in the Mandriva section, but thought I might have better luck resolving my problem here. Here is my original post, and a link to the thread:

So under the tree this year, the fat man left me a new Dell Latitude X1 subnotebook. It's got a 12.1" WXGA widescreen display at 1280x768. I got Mandriva 2006 installed okay, but it will only display at 1024x768. The display is stretched to fit the whole screen. I tried using the "Change The Screen Resolution" tool in the Mandriva Control Center to switch to 1280x768. But when I switch to 1280x768, the display is bigger than the screen, and I have to scroll left and right to see the entire thing (it's like it's still "stretched to fit", just at a higher resolution). I did some reading and found the 855resolution and 915resolution tools to change the vbios resolution for the Intel 855 and 910/915 chipset, but there's not really any instructions on how to use it that I could find. So after reading vague instructions for a different distribution, I got as far as installing an rpm for the 855resolution utility and patching one of the resolutions to 1280x768, but the instructions past that were for a different distribution, and I couldn't get it working (apparently you need to add a startup script after you patch the vbios so that it will use the patched resolution setting when you reboot). Can anybody help me out? Either with the 855 or 915resolution utilities, or some other creative solution?



I downloaded and installed from source the 915resolution utility, followed the instructions in the readme, got one of my resolutions patched to 1280x768, changed my xorg.conf, and added /usr/bin/915resolution 5c 1280 768 to "rc.local". I restarted, and it's the same thing as before: my display is wider than my screen. Any help would be great.

As it turns out, the rc.local script is symlinked to the file S99local in "etc/rc.d/rc5.d" . The problem is that the display manager also starts in runlevel 5, and is named "S30dm", so because it has a lower number, it starts first. I just changed the name of S99local to S01local, and now everything's fine. Hope this is of help to somebody. I think I'll put up a review on linux-on-laptops too, in case anybody else runs into the same thing.

For future posts:

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
