    Installing Linux w/ Lilliput 8" Touchscreen LCD

    Hello all,

    I just received my Lilliput 8" touch screen today. I hooked it up to my Mac Mini and reinstalled Mac OS X to make room for Linux. Once done, I attempted to put Fedora Core 4 Disk #1 of 4 in and boot the installer. I get to the boot prompt just fine, but when a type "linux" -- or press enter -- and it boots linux up, the screen immediately starts to flicker and "roll".

    Does anyone know what settings I may need to pass on the kernel command line to resolve this rolling issue? Is it the refresh rate set?

    Thanks,
    -DJBS

    What if the person who has the answer I'm looking for (instead of a smart a** comment) only reads one or the other thread? I didn't see a thread labeled "Linux and LCD screens", did I miss it somewhere?

    I really hope there are other people who aren't as stuck up here on these forums, otherwise I'm wasting my time.

    P.S. Happy Thanks Giving to all the non-stuck up people out there.

    Most people aren't stuck up. We're not either. We didn't insult you, or tell you search, or call you stupid. If I could help you, I would.

    But, what we are telling you is that if you use the forums to get help, don't **** all over them by double posting and getting upset with people who expect you to follow the rules.

    If I was asked nicer to not post on multiple threads, then I would've apologized and moved on. I did not realize it was "against the rules", otherwise I wouldn't have done it in the first place.

    Found a workaround/fix

    Hello all,

    I wanted to post an update and let everyone know I found a solution for this in case anyone else runs into the same problem. Without finding anything on the web, I decided to dive into Linux kernel sources myself and I found several interesting things.

    Linux attempts to detect the video card in the PowerMAC it is running on (Mac Mini in my case), and then tries to sense what kind of monitor is connected. Based on these values, it sets the internal frame buffer (macfb) to specific values (resolution, refresh, etc). It looks like this driver doesn't allow you to manually specify which mode to use. I will probably add a way to do this later, and figure out what "mode" the Lilliput likes best.

    I found that if you pass "video=ofonly" to the kernel command line, it uses whatever the open firmware has already setup. This seems to work fine for me, and I am now on my way to installing FC4. I think most people don't hit this problem because they install in their house with a normal monitor, and then hook it up to the Lilliput Touch LCD screen in their car afterwards.

    I'll post another update once I've completed my installation, just in case I've hit any other issues.

    if you were asked nicer? were not here to kiss your ***. and if you realize i didnt give you attitude or anything like that when i informed you not to double post. i was giving you a heads up not only because its against the rules but because the guys here will flame the **** out of you. but since you think my comment was a smart *** comment i hope they burn the **** out of you. FLAME ON!
