The newest Lenovo Thinkpads will require you to update Mesa, libdrm, xf86-video-intel and the latest kernel 4.0.0-4x.
On another note and number of patches have been added to improve the functionality of the new touchpad and trackpad buttons.
They can be found in the latest “xf86-input-synaptics”, “xf86-input-evdev”, kernel 4.0.0-4x desktop, kernel-sources, kernel-syms and kernel-devel packages.
That is great news! You found the updated Intel driver for the Xorg X server.
I mentioned the kernel due to a number of patches added recently for the newer Lenovo Thinkpads for 2015.
It now supports the new touchpad and trackpoint buttons.
I’m also thinking about getting Lenovo Thinkpad X1 Carbon 3rd Generation 2015 or the T450 series.
We are very happy that Lenovo listened and got rid of the older touchpad including the annoying interactive strip.
When you get a chance and have confirmed that everything is working, please add your laptop to our hardware database.
I think it is a bit too early to praise compatibility
In the meantime i have the latest kernel from git, the latest firmware images (needed at least for iwlwifi to function), latest xf86-video-intel compiled from source (git clone).
Still having the following issues:
grub video like slow-motion when in graphics mode (looks like standard VGA resolution)
completely unreadable video when booting “failsafe” (white bricks on black canvas)
video loosing sync on graphics console containing systemd’s messages
systemd endless “a stop job is running …” when trying to reboot with a cifs share mounted
color seams on the right and bottom edge of some videos playing full-screen
VirtualBox completely freezing when trying to start a VM (only tried with 3.x kernel yet because i still need to figure out how to compile vbox modules to run under 4.x)
The other issues with synaptics and the function keys i could easily handle, but there must be something going deeply wrong with this new laptop and linux. I was hoping at least intel knew how to drive their hardware but it doesn’t fully seem to be the case.
The resolution for Grub2 can be adjusted using Yast2 Boot Loader.
Start Yast -->System -->Boot Loader.
Click on Kernel Parameters tab
Under Vga Mode, click on the drop-down arrow and select a higher resolution. Try 24-bit.
Under Console resolution, click on the drop-down arrow and select a higher resolution.
Click on Desktop Effects–>Advanced tab.
Set Compositing type to OpenGL 3.1.
Qt graphics system should be set to Native.
Reboot your laptop.
Can you post your Xorg.0.log? In the meantime, I would create a Xorg and systemd bug report with Bugzilla.
PS If you are using btrfs you may consider using ext4.
changed from “Unspecified” to 2560x1440 24 bits (mode 0x37f) -> no change in appearance

Changed from GL2.0 to GL3.1, Qt was already set native, rebooted
There was no change in appearance, however, i double checked the color seam issue on videos. I discovered only videos played by kaffeine exhibit the issue. Playing the same video with mplayer makes it disappear, so this could well be a kaffeine and/or underlying codec problem. I have attached Xorg.0.log below anyway because it reveals information about my ill-behaving machine. But facts suggest that intel Xorg driver is not the culprit here. http://paste.opensuse.org/66738763

[drm:gen8_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
in dmesg when switching between FB and X VTs
I’ll better start a separate thread for both the FB console issue and the Grub issue, respectively.
I’ll file a bug with virtualbox.org for the VirtualBox kernel crash issue.
@Romanator: will you file the systemd cifs shutdown bug? (I have experienced it on 5 machines, both OS 13.1 / OS 13.2)
Let’s hope I can start to use this $2500 paperweight one day Fortunately, I still have got an X1 Carbon Gen.1 as a workhorse where OS13.1 has run smoothly ever since its first install.
Unfortunately I can’t file the systemd bug report as the Bugzilla people will be asking for additional information about your machines.
This may include uploading files.
I did that a couple of days ago. it somewhat fixed the distortion artifacts at the price of a horrible performance: viewing a flash video full screen was impossible with uxa driver method.
But, i am currently happy with the results of the xf86-video-intel driver i pulled from freedesktop.org git. So X is ok. I previously mis-attributed a kaffeine/gstreamer bug to xf86-video-intel.
For freeze ups add to line GRUB_CMDLINE_LINUX_DEFAULT
i915.semaphores=1
to /etc/default/grub
Run grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot.
Tried it and it actually does freeze up KDE start so i reverted the change.
In response to the “[drm:gen8_irq_handler [i915]] ERROR CPU pipe A FIFO underrun” message looks like the kernel.
I believe that we have to leave it up to the Bugzilla people to resolve this issue.
Phoronix has tested Ubuntu, Fedora and openSUSE Tumbleweed as running out of the box on your laptop.
If you don’t want the entire Tumbleweed installation. You can update specific packages from the Tumbleweed repo to resolve this problem.
It’s worth giving it a try.
I actually read the post by Phoronix even before I got my nex X1. I don’t know what exactly he has tested. I have actually tested Ubuntu 15.04 and Kubuntu 15.04 which both had similar video problems. They just don’t appear directly during installation. Furthermore Phoronix’ configuration does not include the high-dpi display that i have. My X1C 1st gen. (1920 resolution like Phoronix’) also did never exhibit video issues.
Well, let’s close this Thread. The Xorg distorted Video issue (initial topic) was solved by a fresh xf86-video-intel from git, so that’s a success at least.
Fortunately, I still have got an X1 Carbon Gen.1 as a workhorse where OS13.1 has run smoothly ever since its first install.
