Hi,
This is a report of things don't work on an Acer Aspire AS5536. http://us.acer.com/acer/productv.do? LanguageISOCtxParam=en&kcond61e.c2att101=57644&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=447&ctx1.att21k=1&CRC=1731859535
............................................................................
Is X running at the correct resolution?
Not sure, since xwininfo is not installed. but xrandr reports wrong resolution.
3-D Acceleration?
Probably not, since glxinfo is not available/installed.
Does the trackpad work? Partially.
* Does it move the mouse pointer? Yes * Does the right hand side emulate a mouse scroll wheel? No * Does the trackpad single click, click & hold work? No
Does the sound work? Yes, the speaker-test works.
Does pressing the volume hotkeys raise, lower and mute volume?
Yes for raise, lower volume -- there is dialog appearing on screen showing the current volume. But mute doesn't work.
Does pressing the sleep button cause the machine to sleep? No
Is CPU frequency scaling supported? No
sudo invoke-rc.d powernowd start
shows the error
required sysfs object not found.
............................................................................
The most important thing to note is that, all above things don't work under Grml Medium works fine out of box in Unbunto.
Most of them are fundamental features, IMHO. Hope that future Grml Medium may include some of the above fundamental features.
Thanks

but 'soundtest' fails on Grml Medium.
Power Management of the screen? No.
The machine's screen should go blank and then suspended after some time. but it isn't.
Does pressing the sleep button cause the machine to sleep? No
How can I make it happen if I've done the HD installation?
Thanks

Looks like pretty fresh hardware, right?

xdpyinfo | grep -e resolution -e dimension

Absolutely not a goal for live grml.

Please use cpufreq-info instead.

[1] Please grab a sid based daily ISO from http://daily.grml.org/ and give it a shot. They provide current X.org and a newer kernel version. And please be aware of the fact that some of the above tested features aren't in the core goals of live grml (even though it's nice if it works, but usually we put our developers time in other areas), whereas Ubuntu is optimized for those desktop tasks.

Thanks for your reply mika.
Just FYI, neither xdpyinfo or cpufreq-info is available in the Grml Medium that I have, which is grml-medium_2009.05. I'll try a sid based daily ISO also.
thanks

The full tool collection is available the full version of Grml. ;)

It’s frustrating when you hit that wall with a specific distro where the basics like CPU frequency scaling or trackpad gestures just don't play nice out of the box. Seeing that error about the "required sysfs object not found" is a classic headache—it usually feels like you're fighting the hardware instead of using it. It reminds me of a struggle I once had with a home server build. I was trying to run everything off a budget 400-Watt power supply https://serverorbit.com/power-supplies/network-power/400-watt, and I kept getting weird stability issues that I initially blamed on the OS. It turned out the unit wasn't providing clean network power to the peripherals under load, which caused some of the hardware sensors to flake out, looking exactly like a driver issue. Sometimes, what we think is a software limitation is actually a deeper power delivery problem. Given how well Ubuntu handles this specific Acer model, do you think the issue with Grml stems from missing kernel modules for this hardware, or is it more of a configuration oversight in the base install?

No idea about the "required sysfs object not found", what is the exact error message and when/where do you see it?

As a starting point, which Grml version + flavour did you try?
Also, which kernel modules are loaded when Ubuntu is running, vs what is running (and possibly missing) compared to when running Grml?
