I have no trouble with X. ALSA was simple once I finally realized that the .deb package wasn't creating a required link from /etc/modutils/alsa -> /etc/alsa/modutil/0.9. APM is definitely toast. PCMCIA works fine for me, but that seems fairly dependent on the cards you're using. > My advices: > > About ACPI: just forget 2.2.x kernels since it is now reliable (>= 2.4.16 I agree. > But there is still one main problem: it seems ACPI really hates to share > its IRQ (9) with any other devices.

I'm getting the kernel messages: IRQ routing conflict for 01:03.n, have irq 9, want irq 5 but everything is working. You are supposed to be able to turn off the ACPI handling of irq routing with a kernel parameter (I think 'pci=noacpi') at boot time, but I haven't tried it. It might make a difference for you. I'm really just getting into ACPI, and haven't tried the latest patch. > So I traced a little, read the doc to find a way to say the kernel to > provide it another IRQ as Windows does (it gives IRQ 5 to the PCMCIA > driver).

So XDM is enough to power off Where is the 'suspend' on a inspiron 2500? The blue suspend key (Fn-Esc) doesn't appear to send any signal that's caught by ACPI (but I'm just using the ACPI support in the kernel, not the latest patch - would the patch help?). > > About the touchpad: my /etc/gpm.conf: > device=/dev/psaux > responsiveness= > repeat_type=raw > type=ps2 > append="" > sample_rate= > > and XF86Config-4: > ... > Section "InputDevice" > Identifier "Touchpad" > Driver "mouse" > Option "CorePointer" > Option "Device" "/dev/gpmdata" > Option "Protocol" "PS/2" > ... > > I prefer to say it as I personaly spent sometimes on it. > > Also, I experienced NO problem about 16bit mode under XFree86. > If you want my complete XF86Config-4 to test, just ask me. > > For additionnal information about it (french/english): > > http://babou.org/equipment/lebanon.fr.html > http://babou.org/equipment/lebanon.en.html > > 2) My questions: > ---------------- > > About this famous suspend-to-disk partition, actually I directly put > another hard disk in the laptop (from my previous one) exchanging the > two hard disks.

First, the 'firmware' supports those sleep levels, but afaik there's no software behind it to actually force a suspend. In fact, on the acpi-devel list in the last couple of days Pavel Machek (one of the developers) said: "[If you say S4 works I'll not believe you, and if you say S3 works, I'll be very pleasently surprised. S1 has some chance of working.]" Just like apcid runs init when you press the power button, I think we'll need to supply the functionality to do the suspend to disk. I haven't finished reading the acpi docs either... My experience was that S1 seems to work (echo 1 > /proc/acpi/sleep), but the inspiron is incapable of resuming from it (the keyboard can't regain control). Hitting the power button does put it through an orderly shutdown. S4 is ugly. I haven't checked exactly what it did, I just know it wasn't nice, and I couldn't power down properly :-) S5 looks like it wanted to do a suspend to disk but all it really did was an abrupt power-off. If you're interested in working with me on this, I'd suggest we keep trying and report back to this list and acpi-devel with our results. We seem to be at a pretty similar point. > I gave a look at the suspend-to-disk patch, because I experienced how > Windows 2000 does suspend-to-disk: it actually uses its own filesystem, > creating a hiber....sys file.

I haven't tried it yet - in fact my next change to the kernel was going to be to add ext3 because a number of testers of acpi have enthused about the value of journaling filesystems when they're testing power management. > Also, I cannot switch off the display.

Not having a dark room, I can't be certain it really powered off, but it blanked the screen. I know when my screen blanks normally (after 15 minutes of inactivity) it does _not_ power off. > It also does not switch off on the text console. > > Last question: I saw that under windows, the touchpad driver can make the > right side of the pad working as scrolling wheel.

I quit trying to make the TP do anything but ordinary mouse movements, because I found it too flakey - and I hate how it works under Windows ME - but if you want it to work as a wheel mouse, you'd definitely need it to be an IMPS/2 not a PS/2. I guess I have it working as a wheel mouse in WinME but I can't figure out how to control the wheel function. It's always scrolling on me when I don't want it to. Perhaps if I had this functionality in Linux I'd get use to it, but I only use Windows for Quicken :-) derek -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
