[lucid] Blank screen with KMS on Thinkpad X201 with Arrandale (i915)

[Hendrick Musche]

Hi all,
On my new Thinkpad X201 with Core i5 and integrated Arrandale graphics with lucid i get a blank screen (no backlight) as soon as the i915 kicks in during boottime. Booting continues, i can hear the loginsound, but the display stays dark. External screen shows a picture, although with wrong resolution. Booting with the i915.modeset=0 results in working graphics, but only X with vesa. I tried several kernel-versions, including karmic livecd and the newest daily build from the kernel mainline ppa, both 2.6.33 and 2.6.34, all to no avail. The only kernel that works is from this ppa (https://launchpad.net/~csurbhi/+archive/karmic-stable) from bug #515246, but I couldn't isolate why. This could be a duplicate of that bug, but it has been marked fixed, but still remains with me.
The problem seems to be that the i915 cannot initialize the internal display properly. Following snip from syslog:

[Allan Day (allanday)]

I'm experiencing the exact same thing. New x201, everything works, but nothing is displayed on screen.

[Greg Rayburn (greg-motava)]

Same here, get the black screen when booting up. Lenovo X201, although for me the only kernel that works currently on Lucid is 2.6.32-14. Anything newer than that and I get no graphics.

[Allan Day (allanday)]

I'm still experiencing this bug. A few more details: I've tried a number of Lucid dailys as well as the recent beta 2. I've also tried Karmic and Fedora 12. They all have the same problem. (This is on an x201 with an i5.)

The problem itself: a blank laptop screen. Everything seems to work fine(ish) apart from that. Login comes up as normal, and I can use an external monitor. I get the following error message:

[drm: intel_crtc_mode_set] *ERROR* Couldn't find PLL settings for mode!
[drm: drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc f426800

Needless to say, I'm anxious to get this working!

[Hendrick Musche (hmu)]

Ok, if 2.6.32-14 is the last working kernel version, I tried to find out the changes to -15. One line related to Ironlake (the GPU integrated in the Core i5) is this in upstream kernel changes:

* drm/i915: disable hotplug detect before Ironlake CRT detect

Corresponding patch is available at http://lwn.net/Articles/375436/. IANAKernelHacker, but my guess is its got something to do with this.

[Hendrick Musche (hmu)]

Just FYI, the problem persists with linux-image-2.6.23-20, at least for me.

[Greg Rayburn (greg-motava)]

Just tried 2.6.32-21 and the problem is still there.

[Dennis Stone (dennis-infomaniak)]

This means that people like me that want to install Ubuntu 10.04 RC on their X201 need to specify "xforcevesa i915.modeset=0" at the boot command line for the installer, then in grub for the first boot, and finally edit /etc/default/grub to make the change permanent.

[Jonathon James (isamaranga)]

I can confirm that the screen of my X201 remains blank when trying to install and boot Ubuntu 10.04 RC. The workaround suggested by Dennis Stone works for me, although I cannot enable visual effects (an admittedly small caveat). Hopefully this will get resolved soon.

[Jonathon James (isamaranga)]

I almost forgot: my kernel version is 2.6.32-32.32

[Jonathon James (isamaranga)]

^^^ wrong version - should be: 2.6.32-21.32

[Jeremy Foshee (jeremyfoshee)]

Hi Hendrick,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

    [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Jonathon James (isamaranga)]

Not sure if this is helpful, but in the course of my experiments, I've discovered that I only need to add "i915.modeset=0" to the boot line in order get graphics. The "xforcevesa" option is not necessary for me.

[Greg Rayburn (greg-motava)]

Tried Mainline version: linux-headers-2.6.34-999-generic_2.6.34-999.201004281008_i386.deb & linux-headers-2.6.34-999_2.6.34-999.201004281008_all.deb

But problem is, it won't boot up now, just sits there with a flashing cursor in the upper left corner.

[Hendrick Musche (hmu)]

@jeremyfoshee
just tried the daily version from the ppa (2.6.34-999.201004281008), no change. Sorry for the question, but do i remove the needs-upstream-testing tag anyway?

[Jonathon James (isamaranga)]

Just updated to 2.6.32-22 from lucid-proposed and the bug persists.

[S Johnsen (ubuntubugs9901)]

Hi,
Had the same problem with my new X201 (core i5), but managed to get a working 9.10 setup, that is everything including the eye-candy works, with these instructions:
http://www.linwik.com/wiki/using+the+intel+arrandale+intel+graphics+media+accelerator+hd+with+ubuntu+9.10

HTH

[Jonathon James (isamaranga)]

@ Stian Flage Johnsen,
The newest xorg packages and mainline kernel (either 2.6.32 or 2.6.33) do not solve this issue for me in Ubuntu 10.04. Still need to boot with i915.modeset=0 to get graphics.

[rampage (gfoster9055)]

I have a Toshiba Satellite A505-S6020, 9.10 installs ok basic graphic, NVIDIA drivers install fine. I straight 10.4 install gets me the black screen (no back light either) before the grub menu comes up. I have the i5 with 310M graphics, will help with anything i can, I would love to run 10.4 and get the other issues fixed also.

[Andy Whitcroft (apw)]

@rampage -- you mention an NVIDIA chipset for your issue, this bug is specifically about Intel graphics and so you must have a separate bug. Please could you file a new one with ubuntu-bug linux. Thanks.

[Andy Whitcroft (apw)]

@Hendrick -- could we get a dmesg from a 'boot to black' 'KMS enabled' boot from your system with -proposed enabled and the -22.33 kernel or later installed please. The original dmesg is somewhat old and predates the update to DRM .33. Thanks a lot!

[Andrew Bortz (abortz)]

I also have a Thinkpad X201, with the same problem, with the same dmesg output as earlier in the thread. In an attempt to isolate the problem, I tried the following kernel versions:

mainline 2.6.32.9 -- works
mainline 2.6.32.12 -- works
ubuntu 2.6.32-14.20 -- works
ubuntu 2.6.32-15.22 -- works
mainline 2.6.33.1 -- doesn't work
ubuntu 2.6.32-16.25 -- doesn't work
ubuntu 2.6.32-22.33 -- doesn't work
mainline edge -- doesn't work

Turns out -14.20 wasn't the last ubuntu kernel to work. I wasn't able to get my hands on debs for ubuntu 2.6.32-16.23, but I suspect it wouldn't work as well. Looking at all the changelogs, all this points to the update to DRM .33 as the culprit. But that is a big patch, and I'm totally out of my league. Help?

[Jonathon James (isamaranga)]

@Andrew Bortz, where do you find the old ubuntu kernel versions?

[Martin Th. (ma-th)]

@ Jonathon James: http://kernel.ubuntu.com/~kernel-ppa/mainline/
Anything new here? I've also tried 2.6.34 RC6. Didn't work out...

[Hendrick Musche (hmu)]

@andy whitcroft: sorry, i'm currently on a three month vacation and have no means to ssh to my machine to get the dmesg output. Maybe someone else here can help?

[Stefan Gold (stefan-gold)]

Hi,
here are my dmesg from a 'boot to black' 'KMS enabled' boot of the latest lucid 2.6.32-22-generic kernel and the latest 2.6.34-rc7 mainline kernel.

The problem occurs on my X201 with those kernels too. Btw, I'm using the recent BIOS 1.14-1.08/1.08 from Lenovo, released 2010/04/23.

[Steve Conklin (sconklin)]

It appears that the following upstream patch may be the fix:

b91ad0ec52770dcb622b94fc1f57e076686f427a drm/i915: Rework DPLL calculation parameters for Ironlake

Here's an upstream mailing list thread about it:
http://markmail.org/message/4yq3ejcke7uhe63i#query:+page:1+mid:ljfvjcr7or7yrd6n+state:results

I'll have a look and see about getting it into a test kernel, I'm busy at UDS this week

[Steve Conklin (sconklin)]

The patch above is already in the tree as part of the .33 drm backport, so I'll continue to investigate

[Steve Conklin (sconklin)]

This red hat bug no longer applies as it is now being used to track a network card issue.

[mabawsa (mabawsa)]

I am awaiting delivery of an X201 and wondered if anybody has tried the following ppa?

https://launchpad.net/~glasen/+archive/intel-driver

[Alexnader Trofimov (a-trofimov)]

mabawsa, it doesn't work:(

[Stefan Gold (stefan-gold)]

I've tried a self-compiled 2.6.33.4 vanilla kernel, in which I assume the patch from #27 is already included (Please correct me if not!!!). Unfortunately, that approach hasn't solved the problem yet.

[Jeffrey Baker (jwbaker)]

The supposed workaround hard locks my laptop with a flashing caps lock LED, with or without xforcevesa.

[Mubes (dave-marples)]

Datapoint; With latest X201 BIOS (BIOS: 1.14 / ECP: 1.08/1.08) from lenovo I can get i915 driver working on the external display by removing the modeset and vesa elements from the kernel command line. I also get full effects etc. and i915 is in use according to lsmod. This is using 'stock' 64 bit 2.6.32-22 generic kernel. I cannot get any display on the LCD panel at all, although It will wake up the backlight if I try to switch on both screens.

This new BIOS has improved a few items - I understand that the ACPI is now more stable and certainly the display on the external (4x3) monitor 'fits' a lot better than it did before.

Not sure it's much use, but just in case....

DAVE

[Eshat (eshat-deactivatedaccount)]

Same issue here on the Debian (sid) side using a X201 with latest BIOS from 23 Apirl.
I get same blinking CapsLock and freeze as Jeffrey Baker described.
Also I would like to add, that the blank screen remains with kernel 2.6.34-1-adm64 (from experimental and a self compiled one).

Booted with an external monitor connected (which works with wrong resolution, as mentioned above) my syslog says:

anyone knows if the kernels from this PPA:

I tried a 2.6.34 kernel from that repo and it didn't help at all.

In the Xorg bug I linked here, there is a proposed one-line patch that some commenters report has worked for them on a X201, although others say it doesn't. Still others report that BIOS updates fix the problem (didn't help me).

[Thomas Uehlinger (thomas-uehlinger)]

I can confirm that the following patch solves the bug for me (X201, latest bios version 1.14, patch applied to the offical 10.04 kernel 2.6.32-22)

+++ intel_display.c
        bool found;
        /* approximately equals target * 0.00488 */

Thomas, Your patch solves the problem for me too. Typing this from a machine running with the new drivers...

DAVE

[mabawsa (mabawsa)]

So I want to get this working. How do I do it?

[Jonathon James (isamaranga)]

Yes, please provide information on how to apply the patch. Is this
something we need to perform directly on the source code?

[Eshat (eshat-deactivatedaccount)]

Also workes for me on Debain sid with current kernel 2.6.34 from kernel.org.

To apply simply add

err_most += 50;

to line 882 in drivers/gpu/drm/i915/intel_display.c before compiling the kernel like described here:
http://bugs.freedesktop.org/show_bug.cgi?id=27471#c12

[Jeffrey Baker (jwbaker)]

Yep, fixed for me too.

[Jeffrey Baker (jwbaker)]

And here's the corresponding headers. For whatever reason after I installed this kernel I had to manually instruct update-initramfs to make a new initrd, and then update-grub manually as well.

[mabawsa (mabawsa)]

Just to recap
run failsafeX from the recovery tools (I had to append the i915.modeset=0 to the boot options)
download and install Jeffrey's debs.
Run:
sudo update-initramfs -c -k 2.6.32.11+drm33.2-x201
sudo update-grub
sudo reboot

Thanks Jeffrey Windows 7 was really bugging me. Will this patch be pushed into release?

[Mark (mark-wege)]

Cah someone give some more detailed instructions how to put this in to a kernel? I am running the 32 bit version of Kubuntu so I can not make used of this compiled packages. Furthermore I have already a patch for the problems with the GOBI WWAN from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/554099/comments/14 which I do not want to loose.

[aleij (alejoduque)]

yes, i can also confirm that running: sudo dpkg -i on the .debs (hint @Mark, the linux-image one is the kernel) submitted by jeffrey baker worked well, now i can suspend resume and control the brightness of the screen. this will dramatically improve my battery times.

[Mark (mark-wege)]

@aleij: My problem is that I can not use this precompiled deb-package because I have another patch already. That is why I need to know how to patch and compile the sources to do it myself.

[Jeffrey Baker (jwbaker)]

Mark, since you already have a custom kernel package with your local
changes, it stands to reason that you already have a patched kernel
tree on your system somewhere. If that's the case, simply apply the
patch from this bug and rebuild your package. I use make-kpkg but
I've been told there are more Ubuntu-like ways of building the kernel.

[Mark (mark-wege)]

@Jeffrey: I have edited the sources as in the patch above. The problems is that the instructions in the above mentioned bug appear to be very specific of rebuilding only the parts that needed and copying them. So I do not know what I have to do to extend these in a way that it works for the above patch too.

[Anthony Liguori (anthony-codemonkey)]

I can confirm that the package in #45 fixes the problem.

[Martin Th. (ma-th)]

Also for me the debs from Jeffrey fix the 10.04 bug. But I now run into freezing x-problems with enabled compiz effects. I compiled a 2.6.34 kernel, but I must have made a mistake because it blew up my whole system. Anyone tried this solution with a newer kernel?

[Thomas Uehlinger (thomas-uehlinger)]

@Martin Th.: the abovementioned patch also works perfectly on a 2.6.34 kernel for me (which then also solves the USB resume problem). I'm using the Ubuntu Maverick (10.10) kernel from kernel.ubuntu.com (ubuntu/ubuntu-maverick.git).

[Jeffrey Baker (jwbaker)]

FYI there's yet another new BIOS for the X201 series. Version 1.15 came out on six days ago. There's nothing in the changes that indicate it might fix this error, but I'm going to load it up and find out.

[Martin Th. (ma-th)]

@Thomas: Thanks, works fine for me too. No crash in the last hour even with a zoo of eye candy.

[Jim Gettys (jg-laptop)]

https://bugs.freedesktop.org/show_bug.cgi?id=28070 may be the same bug, being worked on upstream.

[Jeffrey Baker (jwbaker)]

Maybe 28070 and 27471 should be merged upstream?

[Jim Gettys (jg-laptop)]

It isn't clear yet if this is the same bug or not; many things could cause a panel not to work. The HP Elitebook 2540p I have has an eDP internal panel, which Ajax hadn't seen in the wild before at all. The IBM x201 has been out a number of months longer, so it may have an LVDS panel. Until/unless it is confirmed both have eDP displays, it is unwise to presume they are duplicates.

[aleij (alejoduque)]

anyone out there with working kernel that could share its .config file? i will like to try the patch but will like to go on the safe with the so many kernel config options.

[Julien Rebetez (julien-rebetez)]

@aleji: You should follow this guide to compile your kernel : https://help.ubuntu.com/community/Kernel/Compile. Alternatively, use "make localmodconfig" to generate a .config that has the same configuration as your running kernel.

I am attaching the working kernel and headers (recompiled by apt-sourcing ubuntu kernel and applying only the patch - no change to config) for x86.

[Jon Skulski (jskulski)]

i have a new x201 lenovo 3249-CTO and am seeing the blank screen on boot problem

I have successfully booted and installed 10.04 amd64 with the kernel parameters 'i915.modeset xforcevesa nomodeset'.

However, I can not boot the actual install with the same (or no kernel parameters) in both regular and recovery mode.

As far as I can tell, it is the same kernel. Not sure why I am seeing this behavior. Is there more information I can provide?

[Lei Wang (raywang)]

Hi, I also encountered this problem.
the backlight is black when boot up from CD.
After I add a "i915.modeset=0 in the kernel command line", I'm able to boot into desktop, and add the option to /etc/default/grub, and run "update-grub", I can enter to system, but no brightness control, no virtual effect.
#45 might have fixed this issue, but what about i386 package?

[Dave Moskovitz (dave-thinktank)]

How's progress on this?

[Haitao Zhang (minipanda)]

Hi, I can't reproduce this bug on my X201,
Product ID: 3626AM9, Intel i7 + i915, BIOS 1.05
it's working just fine with both Lucid i386 and amd64.
I will try to trigger this bug after upgrade BIOS to latest.
and still need further investigation on more i5/i7 X201.

BTW: some people also report if just "increase the "err_most" variable"
does not solve the black screen problem on X201s in upstream kernel.

[mabawsa (mabawsa)]

Hi here are my details,
Product 3249CTO, Intel i5 +915, latest BIOS 1.15
Blank screen 100% reproducible whenever I try to boot to the default latest kernel.
Works without flaw when I use err_most += 50; and compile the kernel.

Anything else I can do to help debug this please let me know.

[fanofanne (fanofanne)]

Hi, Can reproduce consistently as mabawsa reports. My latop is the x201 (not the x201s)
Product 3626FBU, Intel i5 +915, latest BIOS 1.15.
This laptop screen has a resolution of 1280x800.

[Haitao Zhang (minipanda)]

After upgrade BIOS to 1.15 (6QET45WW), Embedded Controller Verison 1.09
my i7-M620 X201 still won't affect with this bug, but I already reproduce this bug on another i3 X201.
Looks through http://en.wikipedia.org/wiki/Arrandale_(microprocessor) page,
i3/i5/i7 are all in "Arrandale" Family, so it's really confused why this bug only happened on i3/i5.

Thanks for your update, mabawsa and fanofanne,
could guys please help me test whether mainstream kernel also have this bug on your X201?

[mabawsa (mabawsa)]

For me the bug is still present on the kernel downloaded from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/

linux-image-2.6.35-999-generic_2.6.35-999.201006151505_amd64

[Jeffrey Baker (jwbaker)]

Yep, I've tried a number of the mainline versions and they have all had this problem.

[Eshat (eshat-deactivatedaccount)]

I compiled the Current 2.6.35 vanilla kernel today, and it also fails showing anything on the LVDS.
I also would like to add, that though patching the kernel with the "err_most += 50;" works for me, but I still get the mentioned DRM error message, when sometimes connecting or disconnecting an external monitor, so maybe the above workaround isn't the best way to solve this.

I am on a Thinkpad X201 with Core i5-540M and BIOS 1.15.
I am ready to provide any needed information and do any testing to help solving this issue.

[Jeremy Kerr (jk-ozlabs)]

A patch has been posted in the freedesktop.org bug (comment 29). Haitao is in the process of building a test kernel with this patch.

[Haitao Zhang (minipanda)]

test kernel uploaded to http://people.canonical.com/~hzhang/554569/linux-image-2.6.32-23-generic_2.6.32-23.38_i386.deb

[Eshat (eshat-deactivatedaccount)]

Applied the patch to 2.6.34 from kernel.org and it works.

However as with err_most+=50 I still get the wrong resolution on external monitor when booting with VGA Cable connected.
2.6.32, which didn't have the KMS bug, booted with correct resolution on external monitor. So maybe someone can check, what changed from 2.6.32 to 2.6.33.

This is the only machine I have with intel graphics. I did try the kernel on a machine with nvidia G8400 and a machine with a Radeon Mobility 9700 and it worked fine.

[Greg Wilkins (gregw-wiltel)]

I updated x201 with kernels/headers from #63/#64 and it now does not have a blank screen.
However, the display does lockup now about once per day. I can ssh into the machine and all looks OK, but X cannot be killed with a gdm stop. It even hangs around after a kill -9. However, one I kill all the user processes (kill -9 -1) and the display then responds to a restart of gdm.

I'll provide more info next time it happens.

[Andrew Klossner (o-launchpad-klossner-org)]

Dave Airlie's patch (mentioned in #85) fixes this problem on my Dell Latitude E6510 (i7-620M Arrandale/Ironlake). I applied it to the upstream 2.6.34 kernel and am running it on an otherwise vanilla fully-updated Lucid.

Hello @Haitao The kernel you provide works for me, but it appears that it takes a little bit longer during unpacking the kernel, for me, it takes about 15 seconds.

[Daniel Schröder (ddr-laertis)]

Hi,

I know that you are all experts with upgrading the kernel and so on. I'm not!
Please, can anybody tell me how to update the kernel with the image posted in #97 ?!?
As far as I found out at http://www.unixmen.com/linux-tutorials/780-upgrade-your-kernel-the-safe-way-in-ubuntu-linuxmint I will need 3 files...so why is there only the image file posted?

Please help!!!

[Lei Wang (raywang)]

@Danial, hi, it's very easy, #97 is just a normal deb package, what you need to do is just run "sudo dpkg -i linux-image-2.6.32-24-generic_2.6.32-24.39_i386.deb" (if your arch is i386), and please be noticed that when you reboot, please select the newly installed kernel entry. :-)

[Daniel Schröder (ddr-laertis)]

@Ray Wang
Thanks for the reply. Now I tried as you explained and I also selected the right kernel at the boot procedure. So here's what happend:
No black screen anymore (yeah) but a blinking cursor remains for ever. However, now the brightness keys are working.
Really got frustrated by this "bug"... :o(

It appears the patch in question is now officially upstream and included in the upstream v2.6.35 kernel:

Since Maverick has already been rebased on top of upstream v2.6.35, it subsequently already contains this patch. I'm therefore marking the Maverick linux task as Fix Released. The Lucid task still remains open and going through the SRU process.

[Martin Th. (ma-th)]

I use this now on my x201: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35.2-maverick/

[Daniel Schröder (ddr-laertis)]

yeah nice one...finally #127 works for me!

edit:

worked for me!!!!!!! terrible thing happend, after trying the X201 with docking station xserver could not start,
even without docking station no graphic appears since xserver error is somethin about:

(EE) intel(o): No kernel modesetting driver detected.
(EE) Screens(s) found, but none have a usable configuration.
Fatal server error: no screens found

What the **** is the problem here....I donnt know if I should either cry or destroy the laptop for gods sake...

edit:

working now quiet good every 20th startup or so. the 19 times before that every time a different error occurs. sometimes even the blank screen appeared again. other times the touchpad did not start and therefore xserver stopped.

might be because of the maverick alpha version?

[Cima (andrea-cimatoribus)]

On my machine I don't really want to test an alpha release of a kernel, but I gave a try to #127. It doesn't boot on my laptop (core i5 540), but I think that's not connected with graphics but something else. Anyway, the good thing is that I can see the normal splash screen, so the screen doesn't go blank after grub. There is hope...

I've updated my Lucid Installation to the latest Maverick alpha and

Booting continues, i can hear the loginsound, but the display stays dark. External screen shows a picture, although with wrong resolution. Booting with the i915.modeset=0 results in working graphics, but only X with vesa.

Have a brand new i5 540-based x201 and encountered this issue with 10.04 x86_64. #107 is working for me as well. After deb install and reboot X would not start though:

  (EE) VESA: Kernel modesetting driver in use, refusing to load
  (EE) No devices detected

Restarting X and removing /etc/X11/xorg.conf seemed to take care of it. Found the fix here:

FWIW, I took the Maverick Kubuntu amd64 10.10 beta live CD for a spin today, and everything seemed to work beautifully.

hi dave, have you tested the analog video out with a 2nd display?

[Dave Moskovitz (dave-thinktank)]

Yep - works!

i installed the beta and i still have the problem with a second monitor, when it is plugged in during boot. when plugging in after the start up, it works most of the time. also laptop display brightness goes down...

[Dave Moskovitz (dave-thinktank)]

Well, the latest production kernel, 2.6.32-25-generic-pae seems to fix everything on my X201, so long as /etc/X11/xorg.conf has been either moved or deleted. W00t! It's only taken six months, but I guess it was worth the wait to have a laptop I can use with a projector :-)

[Daniel Schröder (ddr-laertis)]

Finally!!!
I tried the same kernel (2.6.32-25-generic) and graphics is now working perfect, even brightness control.
Did not try external monitor, but will do soon.

Hate to disappoint, but 2.6.32-25 (64-bit) still doesn't work properly on my X201 3249-CTO.

As before, I have to run with i915.modeset=0 and the vesa driver, or I get a hard freeze on boot.

Now I find I need xvideo, though, which vesa doesn't have. Any idea what I can do to help?

[mabawsa (mabawsa)]

Jobo, are you running the latest BIOS?

[Jobo (arkazon)]

I was running 1.17. Just updated to the latest version (1.22). Now it works if I specify i915.modeset=1 on the grub command line. Thank you!

[Hooman (hooman118)]

I just installed 10.10 (64-bit) on my X201 3249-39C and experienced this black screen dead.
My BIOS just updated to 1.22, and the kernerl was 2.6.35-22-generic.

I have to specify i915.modeset=0 to login into tty1.
But no graphic appears since xserver error is somethin about:

(EE) open /dev/fb0: No such file or directory
(EE) intel(0): No kernel modesetting driver detected.
(II) UnloadModule: "intel"
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

[Hooman (hooman118)]

BTW, live CD and graphics installation works fine. It's strange.
Should I try 32bit kernel?

[[e-mail] (rgrover1)]

I upgraded to 10.10 (64-bit) on my X201. I then deleted my /etc/X11/xorg.conf. Now I can boot correctly without needing the i915.modeset=0 boot parameter. Brightness controls also work correctly.
