I wanted to post on HCL, but I’m lacking privilege to edit it. So I hope people who need it will be able to find/google it here.
I would certainly love to know this before getting the laptop.
Laptop: Lenovo Thinkpad x220, Intel i7-2620M, webcam, USB 3.0, 12.5" Premium HD (1366x768-IPS) LED Backlit Display, Intel® HD Graphics 3000, No Fingerprint Reader, Intel Centrino Advanced-N 6205 (2x2 AGN)
Install was flawless including working dual boot with included Win7 Pro 64
I did SW update during the install which solved one or two glitches later.
Though on-line update was not necessary to get the laptop working
Both ethernet a wlan works out of the box
Login to KDE works - though KDE eventually crashes on me - disabling Desktop Effects in System Settings solves the crashes (guaranteed)
graphics - The system works and it is usable for common tasks. There are serious performance and driver quality issues mainly related to Flash playback and transparency/overlay functions - at times this makes it unusable, but it does not crash the system with the exception of KDE. Maybe not all API is implemented/working yet.
Sound works out of the box, though it could be louder
Touchpad - its button is useless although it is great to have for pointing. I use track pad buttons instead - they work like mice buttons should including middle button. So … bless Lenovo/IBM for the treackpad
Screen (IPS in my case) is brilliant in terms of viewing angle colour depth/rendering. Out of the box colour calibration/accuracy is not bad. I calibrated mine and I did see slight difference, but not in the colour tome/perception as is common. The resolution could/should be better than a bit arcane 1366x768. I’d recommend this screen definitely.
320GB,7200rpm,Hitachi - about 1 minute to login screen + additional 1 minute to usable KDE
300GB,Intel SSD - about 15 seconds to login screen + about 40 seconds to working KDE
KDE boot time is really bad - probably result of graphics/driver issues mentioned above.
Battery life - ThinkPad Battery 29++ (9 cell) - between 6-9 hours depending on what is running and the screen brightness. I disabled suspend on closed screen (closing screen will power the display panel) and got about 9 hours playing streaming web radio over Wi-Fi using mplayer with closed screen.

[/size]As you can see CPU is in turbo mode almost for 12% of the time because of lousy graphics driver. This could dramatically improve battery live if addressed.
Overall all, I feel that all good and more or less working. I’m not disappointed. And if Intel improves the driver - I would be over the moon.
On 11. Power usage, 4 gfx and 9. boot times
With suggestion from “oldcpu”, I tried to Ctrl+Alt+F2 & Ctrl+Alt+F7 while waiting for KDE start up. It cut the startup time from over minute to 15 seconds and it reduced time spent in turbo mode from 12% to about 8% this improving battery live by about 2 hours according to powertop.
Thanks for posting this thread. My wife spent some time looking at Netbooks on Friday and Saturday this week (with me checking for GNU/Linux compatibility in parallel for each Netbook she considers) and your post was helpful. She is thinking of purchasing the Lenovo X220.

of course thats not all that useful. More helpful would be: ’ lspci -nnk ’ , but it typically takes users to be using GNU/Linux a while before they learn that the " nnk " option makes a BIG difference in understanding the PCI hardware.

So it appears likely this IS a uvc compatible webcam.
My wife had some hiccups in ordering the Lenovo X220 which have now been sorted. But it won’t be September until she gets the netbook, so it will likely be end September or early October before she allows me to install openSUSE GNU/Linux on it. Dependent on what I read about the SandyBridge graphics and 12.1 milestones, I may just install Tumbleweed-11.4 or openSUSE-12.1 RC version on it instead of 11.4 (where the schedule for 12.1 in that timeframe has):
Thu, Sep 22 2011, openSUSE 12.1 Milestone 6
Thu, Oct 13 2011, openSUSE 12.1 RC 1
Fri, Oct 27 2011, openSUSE 12.1 RC 2
Thu, Nov 03 2011, openSUSE 12.1 Goldmaster
Fri, Nov 11 2011, openSUSE 12.1 Public Release
I’ve read Sandbridge graphics on GNU/Linux can be a finicky beast, which is why I have not yet decided what openSUSE version to install on the laptop.
For the Intel DRM graphics driver in the Linux kernel there is frame-buffer compression clean-ups, high color support, ring frequency scaling, shared LLC support, and hang-check module disabling. Compared to the Linux 3.0 kernel, the driver improvements significantly boost the open-source graphics performance for Intel Sandy Bridge hardware.
Mature Intel Sandy Bridge support. The Intel Sandy Bridge (HD 3000) graphics support has been improved a lot since its January launch. Intel SNB graphics are much faster and more stable in Mesa 7.11, as a number of Phoronix articles have shown in recent months.
… however that is earmarked for Mesa-7.11 and even though just released, I am skeptical that will make openSUSE-12.1 and we may need to wait for openSUSE-12.2. Because of the potential impact of a Mesa update on Tumbleweed, I would be a bit skeptical if we see Tumbleweed-12.1 having a different Mesa version than openSUSE-12.1.
openSUSE will automatically come with the xorg-x11-driver-video rpm that has a recent Intel tarball with the latest open source graphic driver for intel inside. However for best graphic performance, one also typically needs the latest Mesa, which may need the latest X and a very recent kernel. openSUSE may not come with the latest Mesa nor the latest X which may mean one may not have the best graphical performance on openSUSE for the Sandybridge HD 3000 graphic hardware in a Thinkpad X220.
The question as to what Mesa version would be included in openSUSE-12.1 (which is under milestone development) was raised on the factory mailing list, and thus far it appears to be a bit tight and problematic for that Mesa version to make it in openSUSE-12.1. Updating to the the latest X and latest Mesa in openSUSE-11.4 is difficult for an average user to accomplish successfully, with there being a significant risk that that average user may break their system in doing any such update. Its also not the sort of update that would be easily part of Tumbleweed due to the large possibility of significant system graphics breakage in any such update.
just wanted a bit of info on my experience with x220 here.
I got a Lenovo Thinkpad x220, Intel i7-2620M, webcam, USB 3.0, 12.5" Premium HD (1366x768-IPS) LED Backlit Display, Intel® HD Graphics 3000, With Fingerprint Reader and Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01) Wi-Fi adapter.
On a vanilla Suse 11.4 wifi didn’t work and KDE4 graphics had glitches (like random transparent regions or stripes here and there). After I’ve update to Thumbleweed everything started to work as intended, except the Wi-Fi which was unreasonably slow. I had to compile and install latest driver from Realtek site (Realtek). After doing this wi-fi started to work perfectly well.
Oh, after some additional testing it turned out that wi-fi speed drops down drastically after some time. Just after reboot it’s totally o.k., but after some load on wi-fi ti goes down to approximately 1MBit/second. For example if I go to speedtest.net and start the download, first several seconds it goes on 20Mbit/second and then drops to 1Mbit/s permanently. Any help appreciated.
My wife picked up a Lenovo Thinkpad x200 while on vacation (shipped to my sister’s place), but in our case (at my suggestion) she ordered one with an Intel Centrino Advanced N-6205 AGN wireless. I have not yet installed openSUSE on it (my wife is still struggling a bit with tuning Windows 7 on it so she does not want to let me use it yet until she is happy with all her Windows7 apps (this could take a while)). When I get the chance I’ll try openSUSE with wireless on it. Although from what I have read, the Intel Centrino Advanced N-6205 AGN wireless should work well.
When I search the Think wiki for the X220 the Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01) Wi-Fi adapter is not mentioned as an X220 option. I also searched the Lenovo Canada site and the RTL8188CE is not an option for new Lenovo X220s.
I then searched the Thinkwiki site for the 10ec:8176 and found some information on it. That site suggested that the RTL8188CE is only on the ThinkPad Edge 13 series of Thinkpads and it needs the 2.6.38 kernel (which explains why you needed Tumbleweed).
It does appear to me that your X220 is unusual in its configuration.
Is yours an early or late model version of the X220 ? Is the ThinkWiki site not up to date ? Or do you have a ThinkPad Edge 13 ?
Another flaw I’ve noticed is that I can’t get bluetooth mice working. They pair and connect just fine and appear in list of connected devices, but cursor doesn’t move for some reason. Here is dmesg output I get when mice are getting connected:

I experienced a similar (same?) problem. I had a cheapish bluetooth mouse that suddenly stopped responding and I just assumed it had given up on me and settled for the using the Trackpoint for the time being. However, I recently bought a new Thinkpad Bluetooth Laser mouse and that one did not work either. It paired and connected perfectly but did nothing. I tried it on a friends Mac book and the mouse came to life.
After finding nothing in error logs (or anywhere) I went back to 11.4 (from Tumbleweed) i.e. went to kernel 2.6.37 from 3.0.4 and now Bluetooth is flawless again.
