Jump to: navigation, search

I have the ThinkPad X200, and I was wondering if anybody had success with hibernate, sleep, and general power saving?

Also, can anybody find the right framebuffer module and configure it for the 1200x800 screen resolution?

See my Fedora 9 on X200 article

I am now running Fedora 10-Alpha/rawhide on my X200 and everything basically functions (gigabit ethernet, 5100AGN wireless, webcam) except I have to use the vesa driver with xorg.conf instead of the i810 which causes machine crashes. (Apparently it is a known bug upstream and I'm just hoping for some newer xorg-x11-drv-i810 to try out from rawhide). You can set a 1280x800 mode in xorg.conf with the vesa driver.

Hmm... I run debian testing so I may or may not be able to help, but it appears that at least in X in debian, all the intel chips have been integrated into an 'intel' video driver, which works fine for me. The question about the 1200x800 mode was just for setting it in the framebuffer. Also, it appears that the option to disable HV expansion in BIOS has disappeared, has it not?
Hibernate and sleep have the problem of immediately resuming—I don't believe any of the workarounds I found on the ACPI page have any effect.

Hibernate works well with me. Suspend has the backlight issue. The resume is ok but the screen is dark. In fact on certain angles it is possible to see the image displayed...

I mentioned i810 but that is just the package name on Fedora which includes the "intel" driver which is being loaded to operate the card when I tried it. It works after reboot but crashes after suspend/resume and hibernate/resume and there is a bug in the Fedora bugzilla (for rawhide/Fedora 10) already with multiple reporters for Thinkpad X200 models.
Rdemaria: Are you using the vesa driver? I think the backlight works after suspend with the vesa xorg driver, if the i915 kernel module is loaded so it handles power management... however, I have not done enough cycles to be sure everything is reliable. I still have crashes on resume if I use the intel xorg driver. I use vesa and have modprobe i915 in my rc.local.
Yes it works!!!

Harrisonts: I wrote up a hardware issue in the known problems page. I had to have my X200 mainboard replaced, to make it stop resuming immediately from suspend, hibernate, and poweroff actions. It was painful to get through the layers of Lenovo tech support to do this, having to convince each person over again that there was a problem!

Does the X200 have AMT?

Does anyone know whether the X200 has Intel AMT support? I don't see anything in the BIOS or during POST, but I've already destroyed the windows and recovery partitions and cannot check whether there are any other utilities to gain access...

What is the "perfect" desktop kernel .config for the X200?

I'm trying to set up the "perfect" kernel configuration for the X200 when hardware is concerned. Questions like whether or not it should be compiled with legacy IDE support spring to mind, as well as how to take out all drivers and options for hardware not found on the box...

I know running a stock distribution kernel is the recommended way, but where's the fun and learning process in that? For those who want a deeper understanding, kernel tweaking seems to be one of multiple answers.

My first attempt at optimal kernel .config

Since I'm brand new here : Is this the right forum for such a discussion, and is the use of pastebin the appropriate place to share the kernel .config?
