[X200s]: Left side of the screen is considerably darker

Christoph Bier — 2010-03-08T13:33:10

Hi,

on Saturday I found that the left side of the screen of my X200s is
considerably darker than the right when on low brightness (half and
less of brightness). This does not occur on Windows Vista! I tried
to take a picture of it but failed. Any idea what's going wrong here?

Ubuntu 9.10
BIOS 3.11 (installed some weeks ago)
Kernel 2.6.30
TBH I don't know if I ever installed thinkpad-acpi on my own. How
can I determine whether I did or the version of thinkpad-acpi,
respectively?

Best
Christoph

VGA hotplugging

Richard Neill — 2010-03-08T04:46:20

Dear all,

Just wondering - has anyone got VGA hotplugging to really work elegantly 
and seamlessly?

So far, the gnome-xrandr tool (under Lucid) does a wonderful job of 
letting me manually reconfigure the desktop after I plug/unplug a monitor.

But what I really want is for the following:

  1. Plug in VGA cable
         -> Automatically configures dual-monitors as a larger
            screen (*)
-> Ideally, adds a 2nd taskbar to the other screen.
            so that each monitor has its own taskbar.

  2. Unplug VGA cable:
-> reconfigures virtual desktop back to the original
            size. The mouse is now constrained to the actual screen area
         -> All windows are moved back to the visible existing screen
   and resized.


(*) Depending on the user and the use-case, we may want to:
   -  clone the two displays (what happens if the aspect ratios differ),
   -  extend the desktop for dual-head
   -  clone the two displays, and make the internal resolution/aspect
     match the external one (when giving presentations)


Is there any way to do this already? Has anyone written any scripts to 
do it?

Thanks,

Richard

T43 - "no signal" on external monitor

Michael Rodden — 2010-03-07T11:18:24

I've got T43 with Ubuntu 9.10. Has always worked with any external monitor.
However - lost it all of a sudden. Don't know what I did. Checked cables.
Tried Fn F7. No good. Doesn't work on any external monitor. "No signal" is all
I get. Anyone got any ideas? Thanks.

ThinkPad 600... Xubuntu... Maxxed Out Memory

Simon Royal — 2010-03-03T15:01:18

Hi
I have been running my ThinkPad 600 300Mhz P2 with 160MB of RAM with Xubuntu 9.10.  It has been an ok experience. Better than you think. Better than Windows XP.
I ordered another 128MB RAM stick and it arrived today. So it is now maxxed to 288MB and I must say it runs a lot better.
It boots a lot faster and web browsing it a lot better. It doesn't seem to be accessing the hard drive so much, which is a good thing.
On a whole Xubuntu at such a low spec runs very well, but I recommend using the alternative CD which has a text based installer rather than the pretty Ubiquity installer from the regular Ubuntu/Xubuntu CD. As it installs a lot faster.
I have gotten quite attached to this little beast and with the extra RAM it makes it a lot nicer to use. I shall be keeping it a lot longer.

PCI video card in dock II is not detected

Lara Michaels — 2010-03-01T04:30:30

Hi everyone,

I got myself a Thinkpad Dock II (2877, http://www.thinkwiki.org/wiki/ThinkPad_Dock_II) happily thinking I could then use a dual-head video card (I picked one listed on Thinkwiki, the PNY Quadro NVS 280).

The trouble that, when my X31 is docked, the PCI video card does not show up in lspci's output at all. If I insert a Cardbus card into the dock, however, it shows up correctly -- so I know the dock is "alive". (Same goes for the PCI video card itself -- it works on an old desktop system I have here.)

I have tried a number of kernel boot options: acpi=off, pci=assign-busses, pci=noacpi, pci=routeirq and pci=nobios. Still, lspci never shows the PCI card. Strangely, it does show the PCI "bridge" on the dock itself.

Output of lspci -vvv: http://pastebin.com/ehDZ0Twk
Output of dmesg: http://pastebin.com/HFhhFnYX

Has anyone succeeded in using a PCI video card on Linux using the Dock II? What else should I try?

Thank you for any guidance,

~lara

How to get volume hotkeys working again on W500?

Marc MERLIN — 2010-02-28T17:39:49

[pleaes Cc me on replies so that I can see them faster]

I've read the list archives, I know ubuntu did something not much loved
where they generate X events on the hardware volume keys.
As a matter of fact, I get those:
KeyRelease event, serial 35, synthetic NO, window 0x6200001,
    root 0x126, subw 0x6200002, time 1337700564, (42,27), root:(550,1045),
    state 0x0, keycode 122 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

So, with an ugly hack, installing xbindkeys, and:
gandalfthegrey:~$ cat .xbindkeysrc 
"aumix -v -10"
XF86AudioLowerVolume

"aumix -v +10"
XF86AudioRaiseVolume


I was able to make things work again.

But this made me curious: why can't I get the hardware keys to work at the
OS level anymore like they used to?

My W500's hotkey mask comes with:
gandalf:~# cat /sys/devices/platform/thinkpad_acpi/hotkey_recommended_mask
0x038c7fff

linux/Documentation/laptops/thinkpad-acpi.txt gives the hotkey mask
and 
0x1015  0x14    VOLUME UP       Internal mixer volume up. This
                                key is always handled by the
                                firmware, even when unmasked.
                                NOTE: Lenovo seems to be changing
                                this.
0x1016  0x15    VOLUME DOWN     Internal mixer volume up. This
                                key is always handled by the
                                firmware, even when unmasked.
                                NOTE: Lenovo seems to be changing
                                this.
0x1017  0x16    MUTE            Mute internal mixer. This
                                key is always handled by the
                                firmware, even when unmasked.   

As a result, I tried to add the 0x14 and 0x15 bits to the hotkey mask and fed
gandalfthegrey [mc]# cat /proc/acpi/ibm/hotkey
status:         enabled
mask:           0x03bc7fff
commands:       enable, disable, reset, <mask>

(0x03bc7fff instead of 0x038c7fff)

Yet, using the mute key still works.
When I mute, the vol up and vol down keys do unmute, but this happens in the bios. 

tpb doesn't see the keys anymore (while tpb does see mute), and acpi_listen
does not see the keys either (strace of tpb or acpid doesn't show anything
registering in tpb or acpid when I push vol up and vol down).

I used to have tpb control master mixer volume, which I can't do anymore now.

I guess I can live with making this work through X, but any idea what
changed or what I'm missing?

Thanks,
Marc

Xubuntu vs Ubuntu

Simon Royal — 2010-02-26T10:56:07

HiI am a big fan of Ubuntu. It got me really interested in Linux and gave me the push to leave Mac and Windows behind. I had Ubuntu 9.10 running on a Samsung A10 1.1Ghz Duron and loved it, then the laptop died. I then was given an IBM ThinkPad 600 and after running a few ' lightweight' distros have been quite impressed with Xubuntu 9.10 on it.A few people said not to both with Xubuntu, some even said it was more RAM intensive than Ubuntu. So I am beginning to wonder whether my ThinkPad would run better with Ubuntu rather than Xubuntu.I tried Xubuntu with LXDE window manager and didn't like it and didn't find it very fast. I like the Xfce as it is very close to Gnome. Is it more than just RAM that would pose a problem with Ubuntu as opposed to Xubuntu.I know a bit more RAM would help whatever distro I use, but 160MB seems to handle the basics under Xubuntu, but would it be enough for Ubuntu - even though there are reports Xubuntu is more RAM heavy than Ubuntu.According to the specs Ubuntu only requires a 300Mhz and Xubuntu requires 333Mhz, but I have Xubuntu running on a 300Mhz just fine.Ultimately my question is, would Ubuntu run better than Xubuntu? I am trying to squeeze every ounce of power out of this beast.Regards
Simon Royal

Page left/right buttons

Richard Neill — 2010-02-25T17:12:23

Dear All,

Is there a simple way to make the page left/right buttons (part of the 
Arrow keys) do absolutely nothing?

They map to back/forward in Firefox, which is a great way to lose data 
when one is trying to scroll up and down.

xev tells me they are
   XF86Back and  XF86Forward
so perhaps the best thing is to just xmodmap them into oblivion?

FWIW, I have a similar problem on the Ultranav USB keyboard; but on this 
one, the key actually emits a two-key combination: "Alt + Left-Arrow"
or "Alt + Right Arrow".  This is therefore not distinct from the real 
"Alt" + "X_Arrow", so I believe it can't be remapped.
I just removed the keycap and physically destroy the switch.

But I'm reluctant to do this to a laptop.

Richard

Which distro for ThinkPad T400s

Petar Milin — 2010-02-25T15:53:13

Hello!
I am now in doubt which distro to use for my T400s: Debian testing 
(amd64 net-install) or Ubuntu 9.10? Which one suits this T-version?

Thanks,

Thermal allert for ThinkPad T400s

Petar Milin — 2010-02-25T09:27:39

Hello ALL,

I just installed Debian testing on my new ThinkPad T400s. Everything 
went like a charm, but, when I reboot or shutdown, just before 
everything turns off message appear:
thinkpad_acpi: THERMAL ALLERT: unknown thermal allert received
Please, help: what is this? Is it serious? Any idea? How to fix that?

Also, I would be very happy if I could turn off Bluetooth permanently, 
not having it on every time when I log in. Fn+F5 turns of both the WiFi 
and the Bluetooth.

Thanks!

freeze on thinkpad x61

francesco tartaglia — 2010-02-19T10:57:01

Hi all.
My problem is hard freeze on thinkpad x61 with linux.
I try Debian, fedora 12, Ubuntu 9.10, 8.04 etc
but my Thinkpad keep freezing and they are more and more frequent.
The only way to stop freeze is set ACPI=off.
But this option is limiting because there isn't sound, usb etc.
Maybe right solution is remove only a few ACPI module from BIOS.
Is it a good idea?
How Can I remove this modules from BIOS?

Have you got other idea?


thanks a lot.
bets regards
f.t.

thinkpad stuck on lowest speed [cpufreq, acpi]

D. Sen — 2010-02-18T23:14:53

I seem to have struck a strange problem. The clock on my Thinkpad is 
stuck at the lowest possible speed. Nothing I do seems to be able to 
change the clock rate from its slowest (800000 Hz) speed.

I have tried changing the governor manually, automatically through 
cpufreqd, KDE's power-devil all to no avail.

Both the following are stuck on 800000:

/sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
/sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq

I have tried to manually enter the max frequency into these without any 
success.

The machine/OS details are as follows:

Core 2 Duo processor T9600 thinkpad machine (W500).
64 bit Mandriva 2010.

I notice the following running:

hald-addon-acpi: listening on acpid socket /var/run/acpid.socket
/usr/lib64/hal/hald-addon-cpufreq

Killing those processing also has no effect.

Any ideas?

T400 does not enter C4/C6 sleep state with USB devices connected

Pedro Ribeiro — 2010-02-18T13:34:15

Hi all,

I spent lots of hours trying to figure out why my T400 would not enter
C4 and C6 sleep states.

Here are my findings for anyone which is interested:
- When a USB device is connected, even if it supports USB autosuspend,
the cpu will never go down more than C3 (apparently the mode is
disabled by the BIOS).
- After removing all the USB devices, in AC it enters C4 and in
battery it enters C6.

So one more reason not to use USB devices while on battery...


Regards,
Pedro

T400s BT not working properly

palim palim — 2010-02-16T16:19:31

Hi everyone,

my new TP T400s (2808 D5G) has got a BT-PCI-Card:
$ lsusb|grep Blue
Bus 004 Device 006: ID 0a5c:2145 Broadcom Corp. Bluetooth with Enhanced Data 
Rate II

With Debian Squeeze files can be sent to my mobile phone, but not vice versa.
# hciconfig hci0
hci0:   Type: USB
        BD Address: 00:24:2C:C1:32:C1 ACL MTU: 1021:8 SCO MTU: 64:1
        UP RUNNING PSCAN
        RX bytes:43223 acl:1190 sco:0 events:3020 errors:0
        TX bytes:1255118 acl:5829 sco:0 commands:82 errors:0

 In fact, the TP cannot be detected unless I do a
# hciconfig hci0 piscan
This will make the BT visible.
Though iscan is enabled:
$ cat /etc/bluetooth/hcid.conf|sed '/#/d'|sed '/^$/d'
options {
        autoinit yes;
        security user;
        pairing multi;
        passkey "1234";
}
device {
        name "%h-%d";
        class 0x100100;
        pscan enable; iscan enable;
        lm accept;
        lp rswitch,hold,sniff,park;
}
, the iscan-option has to be set manually.
question no.1: how do I set the iscan-option automatically, as the hcid.conf 
seems to be ignored.
question no.2: how to manage pairing, which does not work initiated from the 
phone.
thanks!
p. alim

Changing display of X61 to one with higher res possible?

Jan Girlich — 2010-02-16T00:11:43

Hi folks,

I got a X61 (7676-A14 bought in Singapore, but I live in Germany) with a
1024x768 resolution and just broke my screen. So now I'm researching
into repairing because my international guarantee doesn't cover Europe
as I just found out.

Anyway, I found the replacement part numbers in the Maintenance Manual
but I was wondering if anyone knows if it's possible to replace the
screen with another one which has a higher resolution like 1400x1050
like some other X61's have.

The Maintenance Manual says those part numbers work for my model, but
they're all just XGA:
13N7094
13N7096
42T0343
42T0435

So if anyone knows if these are compatible to some higher resolution
screens I would appreciate it!

R31 hard drive replacement

James Knott — 2010-02-14T17:46:08

I recall reading about some issues to consider, when replacing the hard 
drive in some ThinkPad models, but I've forgotten what those issues 
are.  Does anyone have that info handy?  I have an R31 2656-6FU.

tnx jk

LCD Life Expectancy

David Woodfall — 2010-02-14T04:30:16

I have a T42 that looks like the backlight has just gone on it. This
was a used display I bought after the original died. Now I'm 
wondering what the expected life of a display is?

The T21 I'm using right now seems to be good so far. No idea of it's
age though it must be getting on a bit.

So how long do these things keep going for?

Also I noticed the screen had a pink tinge to it on boot. Is this a
sign of anything about to go?

T400 on an Advanced Mini Dock - thoughts?

Pedro Ribeiro — 2010-02-14T01:32:56

Aggressive Powersaving

Karsten König — 2010-02-09T13:16:32

Heya,

the new kernels really brought down the power consumption and I am interested 
in getting it a little bit further, on the road I don't use my DVD drive nor 
ExpressCard nor USB nor Firewire nor Touchpad, is there a way to cleany cut 
the power to these devices/buses?

I don't know about VGA and modem, but I think they aren't that easy accessible 
because they are part of the graphics driver and alsa (it does drive the 
winmodem right?)

Or is there nothing to gain? I noticed pulling out the dvd drive was ~0.5W 
less, so I take it getting the other stuff offline might be nice too.

I don't mind echos to some sysfs file, the simpler the better, I just want to 
make a small script which I can run as root to just get power down 
aggressivly.


Thanks for your ideas,
Karsten

tp_smapi won't load after kernel upgrade 2.6.31.12

Jonathan Pritchard — 2010-02-08T02:03:02

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I was wondering if anyone could help me. I'm using Fedora 12.

I was using tp_smapi successfully until my kernel upgrade and now I can
no longer load it using as root "modprobe tp_smapi". I have been using
an akmod and have restarted the akmods service which gives me no errors.

modprobe gives me the following error message:
[root< at >Jon-Laptop ~]# modprobe tp_smapi
FATAL: Error inserting tp_smapi
(/lib/modules/2.6.31.12-174.2.3.fc12.i686.PAE/extra/tp_smapi/tp_smapi.ko):
Invalid module format

dmesg gives me the following output also, which appears to show some
sort of mismatch with regards to the kernel. However I do not know how
to solve this:

thinkpad_ec: version magic '2.6.31.9-174.fc12.i686.PAE SMP mod_unload
686 ' should be '2.6.31.12-174.2.3.fc12.i686.PAE SMP mod_unload 686 '


Thank you in advance for any help. I really need to get this working as
I last set my battery charge threshold to 40%!
