Thinkpad R51e

[Vitus]

Hello!

I'm running Dapper Drake on my IBM Thinkpad R51e. I chose Dapper Drake because it was the first distribution to handle the ATI R200 out of the box. And I wanted something debian alike and a KDE.

Well, most things are working: ethernet, wireless, the screen runs at 1024x768 (not sure which driver, xorg.conf says "ati", system configuration tells me "vesa"). It's just the powermanagment:

- speedstep-centrino.ko can't be loaded. I've found the patch and will applied it when I find the time. In the meantime I'm using p4-clockmod.ko (which complains that I better should usespeedstep-centrino.ko :-))

- running Klaptop that icon disappears on first sleep and some processes hang around. Hibernation puts this machine into some powersaving mode, but it can't be reawakened (see below).

So I disabled this fancy battery monitor and used ascpitool directly. First enabled the powerbutton as wakeup source (acpitool -W 4) and then did a suspend-to-RAM (acpitool -s). The system stopped immediately, LED showed powersaving mode. By pressing the power button fan and disk restarts but screen stays dark (well, flickers once) and the keyboard remains dead. I may then switch the system on and off by pressing the power button but to get a running system I have to do a reset (pull the battery).

With Klaptop running the same thing happens on hibernation. And it doesn't matter whether I'm running on AC or battery.

Any helpfull pointers from you all? It's a nice system otherwise

Hello Vitus,

I run 6.06 B2 on an Acer Aspire 3500.

The only suggestion I can give you is do a search on the forums for Klaptop and see what comes up, I know the power control module isn't exactly 100%.......

Hi Will!

I will do the search for my suspend problems.

For the powersaving it's difficult to understand who is adjusting all those settings. There is the dialog "Systemeinstellung, Laptop/Batteries" where i can select different governours while on batterie/AC. And there is /etc/laptop-mode/laptop-mode.conf where I can select the same and some more. They aren't related, laptop-mode.conf seems to be ignored (unfortunately, there is finer control). And there a powernowd and simmilar programs, but i would like to NOT add another program. Another thing I have to search for.

The speedstep-centrino patch http://localhost.ruhr.de/~stefan/ace...dothan-3.patch is already applied to my dapper drake version, but doesn't support my CPU. /etc/cpuinfo:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Celeron(R) M processor 1.50GHz
stepping : 8

fdiv_bug : no

bogomips : 2995.21


That CPU ID is mentioned on http://www.thinkwiki.org/wiki/Pentiu..._underclocking, but the patch isn't complete and my guesswork didn't work. So I have to stick to p4-clockmod for a while.

So, that's the current state of affairs. The R51e isn't the best solution if one wants linux out of the box

Re: Thinkpad R51e

Hello Vitus,

I think the battery issue is a mixed bag with any laptop, I have not yet progressed that far in my tinkering. Just trying to get a stable desktop up and have my Atheros WiFi chip picked up on every boot.............seems to skip a boot every now and then.iwconfig will show no wireless extensions.
Nothing too serious and I like this distro.

Hi Will!

Yes, I like Kubuntu, too! Looks good, package feeds seem to be well maintained.

As for the Atheros, that's the same card as I have. No probs with it here other than I can't get DCHP to get an address for it as long as the ethernet card is connected. And I've added all settings to /etc/network/interfaces and don't use KWiFiManager, though.

KLaptop is history now on the machine. I'm running barebone with any fancy GUI stuff for power management at the moment. But I will probably test Kpowerdown next week.

If you using it, there is a syntax error on /usr/sbin/laptop_mode, line 606: should be $THIS_CPU_GOVERNOR, "CPU" is missing and prohibits automatic switching of govenors. I will see whether this is already logged as a bug somewhere.

Good Night,
Vitus
