Hello everyone,

I've just received my new laptop yesterday. It's the Lenovo ThinkPad Edge E420S with the Intel HD 3000 graphics, SSD and WWAN module installed. Detailed specs below. So, just after I got home from work I installed my beloved system on it, Ubuntu 10.04. This is what I've been using on my old laptop and which worked like a charm. So does it on this new laptop. The only isses are the graphics solution being stuck at 1024x768 and the fingerprint reader not working.

I'm a software engineer so you can talk a bit more technical with me :)

What I've been researching and finding out by now:

- The resolution issue is due to the kernel/drivers just being too old for this kinda new Sandy-Bridge graphics. On the other hand, newer kernels make me issues with the trackpoint not working (except for the live-install systems) WWAN module being instable sometimes (no PIN asked when connecting/booting and then failing all the time, which is obvious).

--> I've tried newer distros like Fedora 16, Ubuntu 11.10 or Linux Mint 12 which then work for graphics but have the issues I mentioned.

- The trackpoint is recognized as PS/2 Mouse by Ubuntu 10.04 and so I easily can enable wheel emulation for the middle button of the trackpoint. This is also the case with Debian 6 so I'm relating this to the kernel version.

--> Newer distros don't recognize the trackpoint at all in p.ex. the gsynaptics settings manager.

- The fingerprint reader is secondary not just because it's not working very well on linuxes but because I won't use it anyway I assume.

--> I tried openSUSE 12 as well which has a Fingerpint GUI preinstalled and it doesn't recognize it there... But let's leave that issue out for now.

So, if anyone got experience with backport graphic drivers or enabling trackpoints on newer distros, I'd be glad to get some help!

I got it to work flawlessly with a 32bit Ubuntu 10.04 and backport kernel from natty. PERFECT!

I followed the instructions here, works like a charm:

One last little problem I still have... The WWAN module is working perfectly although Ubuntu won't ask me for the PIN everytime and so the connection will fail until I remove the SIM card from the laptop and reinsert it thus forcing Ubuntu to reload the whole thing and then ask for the PIN...

Anyone got any idea what this could be about?

Thanks a lot!!
