I have a W520 (just issued by IBM as my new work laptop). = =A0I installed Ubuntu Quantal on it, which comes with a 3.5.0 kernel, and u= se of the brightness up key yields a very low-level hang that needs a power= cycle to fix.

When booting in UEFI mode with CSM disabled, you get a white on black=

I did some more digging...

I can c= onfirm the following workaround allows full brightness control:

<= br>

nox2apic kernel param

AND

In Device section of xorg.conf:

Opt= ion "RegistryDwords" "EnableBrightnessControl=3D1"

It seems to be a problem with using 64 bit= , a vm, and discrete graphics (all of which I need).

I still have other problems with suspend/re= sume that I need to look into now...

It should just work. What did you have plugged into the mini-dockstation? The ports are of course going to read as disconnected until you have a monitor plugged into them. Depending on the port and the monitor, if you have a monitor that supports multiple inputs, you may need to have the monitor selected to use the input in question or it will still show as disconnected.

-Ethernet cabe (working fie)

To be honest I= don't think I would need to select anything on the external monitor si= de. I expect just to plug the VGA cable and, at least, xrandr -q should sho= w it.

The external monitor works fine, I've tested it with ano= ther pc.

It should just work. =A0What did you have plugged into the
mini-dockstation? =A0The ports are of course going to read as

Hi Theodore.

I resolved it:

1. Plugging the VGA cable to the= dock station

2. Rebooting the laptop

3. Entering the BIOS

5. Saving changes and starting up the OS

So you did have the VGA cable plugged in when you tried running the xrandr command?

We usually prefer that to integers for any boolean variable, and keeping the module_param bool has the advantage that you can use the 'Y' or 'N' aliases instead of '0' or '1'. BTW, using the "_named" variant of the macro seems unnecessary here, given that the parameter and variable have the same name...

I've seen something vaguely similar with ubuntu 12.4 LTS on a T520. I posted here about it: http://marc.info/?l=linux-thinkpad&m=133897083013428&w=2 I never found out what the problem was, I use a wired connection at home to get around the problem and haven't seen the problem reccur in outside networks. I also previously had a problem with ipw2200 repeatedly disconnecting, on a t43P running ubutu, which I solved by reflashing my router (linksys 54G) from DD-WRT to Tomato: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/607064 In both cases, I think the problem started to occur after an update to the kernel. -- Steven J.

I'm not sure if others have been experiencing this issue, but it's something to be aware of. I've had success working around it by either passing "nox2apic" on the kernel command line or by using the nvidia binary module and blacklisting the video module (with the caveat that closing the lid can hang the computer). Aaron Lu has been exceedingly helpful in isolating the issue and I am very grateful for all of his efforts. If any of you are interested in the gory details, take a look at .

Did some more experimentation -- this is how it seems to b= ehave:

pwm1_enable =3D=3D 0

fan speed: 3= 800rpm

pwm1_enable =3D=3D 1

fan speed: 3100rpm to 0 depending on value in pwm (255 to 0)

pwm1_enable =3D=3D 2

fan spe= ed varies automatically according to temperature, but is never above 3100

Are those RPMs too low? =A0Does this me= an I need a new fan?

But it may not need a new fan. Have you cleaned it up yet? The two common defects that cause this are: (1) dirt, and (2) cracked thermal interface. (2) is far more serious, a recurring problem on thinkpads (especially if you ever handle it in any way that causes even minute flexes of the mainboard, such as holding it with just one hand) and you must repair it as it slowly damages it for good.

To repair (2), you need to remove the heatsinks, remove all the old thermal compounds, and replace them with an extremely high performance compound (Arctic Silver 5 is one I can recommend, but others that are medium to high-viscosity, *non* reactive, *non* conductive _and_ as good or better at thermal conducitivty will also work). To repair (1), remove the keyboard and blow the lint away, hold the fan stopped while at it as it is not a good idea to spin it at extreme speed, and that can easily happen while blowing the lint away with compressed air. -- "One disk to rule them all, One disk to find them.

I can second this. I did this procedure on my T400 which went into themal shutdown every time I launched a VM. The procedure is well documented by Lenovo and was at least for me a success, the old thermal grease was very dry and gone on one corner of the CPU, that corner also was of a different tint, I assume to the bad thermal bridge to the fan. > To repair (1), remove the keyboard and blow the lint away, hold the fan > stopped while at it as it is not a good idea to spin it at extreme speed, > and that can easily happen while blowing the lint away with compressed air.

I'll also second the suggestion of thinkwiki.org, it will answer a lot of this sort of question. Off the top of my head... The T-series are what I've always got, and they've always been the ruggedest thinkpads. There is no such thing as a ruggedized thinkpad, AFAIK, but stock T-series thinkpads pass a large chunk of the standard semi-ruggedized laptop tests. I believe the T stands for Transportable. They're made for road warriors, people who will be constantly moving around with them. They're a little lighter, typically have slightly less powerful specs than the R and W series, and have historically had certain extra toughness features added in (like a "roll cage" frame built inside the case). Note: It's hard to say which of these features are available in any given model, I vaguely remember reading about certain of the toughness features that were later added to all models. R stands for desktop Replacement, for a laptop that will spend most of its life doing the same thing as a desktop, i.e. sitting on your desk, but will occasionally be moved around. They're typically heavier, a bit more powerful, a bit less tough. W is (relatively) new and stands for Workstation. They're like the R only more so - much heavier, much better CPU and etc. They were originally designed for as graphics workstations. They don't make a 17" W-series anymore, but there used to be one that had an extra pop-out 10" screen as somewhere to drag your Photoshop tools palette :-). > Depending on the responses to the above question, I'm leaning toward > the T or W series.

Especially with linux, be wary of bleeding edge features. Be especially wary of Nvidia. I have a t520 with nvidia optimus. Of course we all know nvidia's driver support for linux sucks. What I didn't realize was that the thinkpad's external monitor support depends completely on the nvidia hardware. So I haven't been able to drive my shiny new dell 24" monitor.

I bought some Arctic Silver, replaced the old thermal glue on the cpu, chipset, and heatpipe, and rebuilt it -- it didn't make much difference I think. I tried both a very thin layer and a slightly thicker layer as well. Maybe a slight improvement but I still have to be very careful with cpu utilisation to avoid reboots. This laptop has been through hell and is nearly 4 years old so quite likely the original thermal compound was not working as well as it should. I also tried blowing out the dust -- there actually wasn't that much. The airflow can be easily felt around the grilles. The heatsink doesn't seem that hot either, certainly not anywhere near the temperature reported by the core2duo. It seems like either the heatpipe has a problem (unlikely) or the fan isn't going fast enough. It doesn't matter which since the replacement part is a heatpipe/heatsink/fan combo unit and I've got a cheap one on order from Hong Kong now. This probably not the best source of spare parts but I guess this laptop isn't going to last a whole lot longer now... :) On Sun, Apr 28, 2013 at 3:42 PM, Bill Hudacek wrote: > Behavior is consistent, but his results and mine don't agree.
