Right now I'm returning the 4810 that a less technical friend handed to test.
That leaves my personal aspire 3100 (with manually upgraded cpu and ram) as the
only test platform for the time being.
SO I don't know if opening a new bug entry is appropiate, since I can no longer
test both for comparison.
Both laptops had the same issues. Just different GPUs and assorted hw.
Something is broken on the list of recognized laptops on acer-wmi and maybe
that is why, the /proc/acpi/video directory is no loaded anymore?
All dmesg reports when I "modprobe acer-wmi" on K10.10 and opensuse 11.4 Mx&RC1
is:
acer-wmi: Acer Laptop ACPI-WMI Extras
Registered led device: acer-wmi::mail
and nothing else.
I have some knoppix 6.2 an others, somewhere.. Right now I have at hand Ubuntu
10.04 32bit, 10.10 64 bit and System RescuedCD 1.5.8 with 2.6.32 kernel.
When I get back at home, I might try others.
About Acer laptops,etc ; no offense taken. I was just stating my personal
experience and a opinion derived from it. People around me usually brings their
laptops issues, so I had seen many different models and brands.
Its just an intuitive feeling, so lacking any rigor or truth value, but seems
to me that Acer at least use the same "firmware-acpi" for most models even if
they have different hardware. I don't know if by following "style" guidelines
for "look&feel" or actually similar firmware code.
So it seems to me that the kernel used some short-cut via the acpi systems, and
maybe that is which KDE used those shortcuts until Kubuntu 10.10.
But of course since 10.10, I must load acer-wmi manually, which was automatic
in 10.04. And at the same time, 10.10 broke the 3d part on the radeon driver
and other bad stuff.
SO right now my speculation goes around acpi bug, video driver bug (the 4810
had an intel gpu but is still possible), Xorg bug or KDE bug.
I lack better kernel/user space knowledge, to be able to pin point the trouble
between this many layers, and regular life obligations keep me from dedicating
more time. But I'll help in what I can. If you have more suggestions to fix
this, please let me know.
If you can pass this issue to the appropriate upstream would be great. But a
lot of detective work before that.
I'll get RC1 64bit DVD by tomorrow and then I'll make a fresh install, and try
other desktops. I believe only Gnome and XFCE provide the tools for brightness
and powersaving facilities or you have another suggestions?
